Cisco and Intel Demonstrate Interoperability for Open RAN

Cisco and Intel validate interoperability between Cisco Nexus 93180YC-FX3 Switch and Intel® Ethernet 800 Series Network Adapters that feature enhanced timing capabilities for faster and lower cost Open RAN (Radio Access Networks) deployments.

The emergence of Open RAN (O-RAN) standards and solutions is based on the virtualization of network functions and a multi-vendor ecosystem to grow innovation while driving down 5G network operation costs. But an open ecosystem requires each network element to communicate and interoperate with the others. Cisco and Intel have collaborated on a network solution for communications service providers (CoSPs) that delivers on the O-RAN promise.

To address integration challenges faced by CoSPs when deploying Open RAN network infrastructure, Cisco and Intel have combined forces to validate seamless interoperability between Intel® Ethernet 800 Series Network Adapters with enhanced network timing capabilities and Cisco Nexus 93180YC-FX3 network switches.

The Promise of Open RAN

Radio access networks (RANs) historically have been built from proprietary equipment and systems that relied on hardware-centric, centralized, single-vendor components. These systems locked CoSPs into specific vendors and costly integrations, often limiting their ability to scale and innovate. The O-RAN set of standards specifies open, intelligent, virtualized, and fully interoperable RANs supported by multi-vendor interoperability, with a scalable, secure, cloud-native infrastructure that enables service delivery to the network edge, closer to the user.

Solution disaggregation and the use of open interfaces opened the door for the first time for commercial-off-the-shelf (COTS) servers, routers and other networking equipment. But it also increased the need for interoperability between network systems.

One area where this is critical is fronthaul synchronization (Figure 1). The fronthaul in 5G networks is part of cloud-based RAN connecting standalone radio units (RUs) and distributed units (DUs) installed at remote cell sites with centralized units (CUs) that can aggregate multiple DUs and exist in the cloud. This architecture pushes compute power to the network edge and enables support for applications that require high bandwidth and extremely low latency.

Figure 1 Open RAN fronthaul transport configuration incorporating Cisco Nexus 9300 Series switches.

Fronthaul synchronization involves the network adapter and the network switch to ensure that data packet order is accurate, secure, and consistently delivered between data source and endpoints without data loss or corruption so that products from different vendors can seamlessly communicate.

The synchronization plane (S-Plane) controls timing and synchronization between the DU and the RU, and highly accurate timing and synchronization is required for processes such as multiple input/multiple output (MIMO), time-division duplexing (TDD), and carrier aggregation of multiple O-RUs.

Figure 2. The S-Plane synchronizes between the O-DU and O-RU using PTP and SyncE timing protocols.

Validated Interoperability

In this application (Figure 3), interoperability needs to be considered for these S-Plane functions. To address interoperability challenges faced by CoSPs when deploying Open RAN network infrastructure, Cisco and Intel have combined forces to verify interoperability between Intel Ethernet Network Adapter E810-XXVDA4T and Cisco Nexus 93180YC-FX3 network switches.

This collaboration is part of Intel’s interoperability verification program, which features a dedicated Intel lab that evaluates Intel Ethernet 800 Series Network Adapters connected to a wide range of media types and Ethernet switches. The goal of the interoperability verification program is to test and ensure compliance to IEEE standards and also to quality-assure the PHY functionality of Intel Ethernet Network Adapters.

Cisco and Intel successfully performed the following tests:

Test 1: Cisco Nexus 93180YC-FX3 Switch and the Intel Ethernet Network Adapter E810-XXVDA4T successfully passed 25Gbps line rate radio traffic.

Test 2: Clocking features such as 1588 PTP Telcom Profile 8275.1 and frequency synchronization (SyncE) demonstrated.

Test 3: Clock received by virtual DU over the network using 1588 PTP and SyncE.

Figure 3. Example Distributed Unit (DU) deployment using Intel Ethernet Network Adapter E810-XXVDA4T and Cisco N9K-C93180YC-FX3.

Result: Through this verification and quality assurance of interoperability, Intel and Cisco have worked closely to simplify platform integrations and accelerate validation and deployment to deliver a solution that assures ease of integration for Open RAN deployments. Intel and Cisco plan to continue these interoperability tests with upcoming products from both companies.

Conclusion

Cisco and Intel have a long history of collaboration and their commitment to interoperability for CoSP applications is showcased in their tight integration of network adapters and switch solutions for Open RAN applications eased deployments, faster time-to-market, lower total cost of ownership, and scalability and customizability for CoSPs committed to the advantages of O-RAN.

Cisco Silicon One Breaks the 51.2 Tbps Barrier

In December 2019, we made a bold announcement about how we’d forever change the economics of the internet and drive innovation at speeds like no one had ever seen before. These were ambitious claims, and not surprisingly, many people took a wait-and-see attitude. Since then, we’ve continued to innovate at an increasingly fast pace, leading the industry with innovative solutions that meet our customers’ needs.

Today, just three and a half years after launching Cisco Silicon One™, we’re proud to announce our fourth-generation set of devices, the Cisco Silicon One G200 and Cisco Silicon One G202, which we are sampling to customers now. Typically, new generations are launched every 18 to 24 months, demonstrating a pace of innovation that’s two times faster than normal silicon development.

The Cisco Silicon One G200 offers the benefits of our unified architecture and focuses specifically on enhanced Ethernet-based artificial intelligence/machine learning (AI/ML) and web-scale spine deployments. The Cisco Silicon One G200 is a 5 nm, 51.2 Tbps, 512 x 112 Gbps serializer-deserializer (SerDes) device. It is a uniquely programmable, deterministic, low-latency device with advanced visibility and control, making it the ideal choice for web-scale networks.

The Cisco Silicon One G202 brings similar benefits to customers who still want to use the 50G SerDes for connecting optics to the switch. It is a 5 nm, 25.6 Tbps, 512 x 56 Gbps SerDes device with the same characteristics as the Cisco Silicon One G200 but with half the performance.

To achieve the vision of Cisco Silicon One, it was imperative for us to invest in key technologies. Seven years ago, Cisco began investing in our own high-speed SerDes development and realized immediately that as speeds increase, the industry must move to analog-to-digital (ADC)-based SerDes. SerDes acts as a fundamental building block of networking interconnect for high-performance compute and AI deployments. Today, we are pleased to announce our next-generation, ultra-high performance, and low-power 112 Gbps ADC SerDes capable of ultra-long reach channels supporting 4-meter direct-attach cables (DACs), traditional optics, linear drive optics (LDO), and co-packaged optics (CPO), while minimizing silicon die area and power.

Figure 1. Cisco Silicon One product family

The Cisco Silicon One G200 and G202 are uniquely positioned in the industry with advanced features to optimize real-world performance of AI/ML workloads—while simultaneously driving down the cost, power, and latency of the network with significant innovations.

The Cisco Silicon One G200 is the ideal solution for Ethernet-based AI/ML networks for several reasons:

~ With the industry’s highest radix switch, with 512 x 100GE Ethernet ports on one device, customers can build a 32K 400G GPUs AI/ML cluster with a 2-layer network requiring 50% less optics, 40% fewer switches, and 33% fewer networking layers—drastically reducing the environmental footprint of the AI/ML cluster. This saves up to 9 million kWh per year, which according to the U.S. Environmental Protection Agency is equivalent to more than 6,000 metric tons of carbon dioxide (CO2e) or burning 7.3 million pounds of coal per year.

~ Advanced congestion-aware load balancing techniques enable networks to avoid traditional congestion events.

~ Advanced packet-spraying techniques minimize creation of congestion hot spots in the network.

~ Advanced hardware-based link-failure recovery delivers optimal performance across massive web-scale networks, even in the presence of faults.

Figure 2. Benefits of large radix 51.2 Tbps switches

~ Using a common software development kit (SDK) and standard Switch Abstraction Interface (SAI) layers, customers need only port the Cisco Silicon One environment to their network operating system (NOS) once and make use of that investment across diverse network roles.

~ Like all our devices, the Cisco Silicon One G200 has a large and fully unified packet-buffer optimizing burst-absorption and throughput in large web-scale networks. This minimizes head-of-line blocking by absorbing bursts instead of the generation of priority flow control.

Optimization across the entire value chain

~ The Cisco Silicon One G200 has up to two times higher radix than other solutions with 512 Ethernet MACs, enabling customers to significantly reduce the cost, power, and latency of network deployments by removing layers of their network.

~ With our own internally developed, next-generation, SerDes technology, the Cisco Silicon One G200 device is capable of driving 43 dB bump-to-bump channels that enable co-packaged optics (CPO), linear pluggable objects (LPO), and the use of 4-meter 26 AWG copper cables, which is well beyond IEEE standards for optimal in-rack connectivity.

~ The Silicon One G200 is over two times more power efficient with two times lower latency compared to our already optimized Cisco Silicon One G100 device.

~ The physical design and layout of the device is built with a system-first approach, allowing customers to run system fans slower, dramatically decreasing system power draw.

Innovative load balancing and fault detection

~ Support for non-correlated, weighted equal-cost multipath (WECMP) and equal-cost multipath (ECMP) load balancing capabilities with near-ideal characteristics help to avoid hash polarization, even across massive networks.

~ Congestion-aware load balancing for stateful ECMP, flow, and flowlet enables optimal network throughput with optimal flow-completion time and job-completion time (JCT).

~ Congestion-aware stateless packet spraying enables near ideal JCT by using all available network bandwidth, regardless of flow characteristics.

~ Support for hardware-based redistribution of packets based on link failures enables Cisco Silicon One G200 to optimize real-world throughput of massive scale networks.

Advanced packet processor

~ The Cisco Silicon One G200 uses the industry’s first fully custom, P4 programmable parallel packet processor capable of launching more than 435 billion lookups per second. It supports advanced features like SRv6 Micro-SID (uSID) at full rate and is extendable with full run-to-completion processing for even more complex flows. This unique packet processing architecture enables flexibility with deterministic low latency and power.

Deep visibility and analytics

~ Programmable processors enable support for standard and emerging web-scale in-band telemetry standards providing industry-leading network visibility.

~ Embedded hardware analyzers detect microbursts with pre- and post-event logging of temporal flow information, giving network operators the ability to analyze network events after the fact with hardware time visibility.

A new generation of network capabilities

Gone are the days when the industry operated in silos. With its one unified architecture, Cisco Silicon One erases the hard dividing lines that have defined our industry for too long. Customers no longer need to worry about architectural differences rooted in past imagination and technology limitations. Today, customers can deploy Cisco Silicon One in a multitude of ways across their networks.

With the Cisco Silicon One G200 and G202 devices, we extend the reach of Cisco Silicon One with optimized high-bandwidth devices purpose-built for spine and AI/ML deployments. Customers can save money by deploying fewer and more efficient devices, enjoy new deployment topologies with ultra-long-reach SerDes, improve their AI/ML job performance with innovative load balancing and fault discovery techniques, and improve network debuggability with advanced telemetry and hardware analyzers.

If you’ve been watching since we first announced Cisco Silicon One in December 2019, it is easy to see that this is just the beginning. We’re looking forward to continuing to accelerate the value addition for our customers.

Stay tuned for more exciting Cisco Silicon One developments.

Security automation with Cisco XDR

Security Operations Centers (SOC) continue to face new and emerging threats that test the limits of their tooling and staff. Attackers have simple, affordable access to a plethora of cloud-based computing resources and can move quicker than ever. Keeping up with threats is no longer about adding more people to the SOC to watch logs and queues. It’s about leveraging automation to match the speed of your attackers. This past April, at the RSA Conference in San Francisco, Cisco announced our new eXtended Detection and Response (XDR) product: Cisco XDR. Cisco XDR combines telemetry and enrichment from a wide variety of products, both Cisco and third party, to give you a single place to correlate events, investigate, and respond to automatically enriched incidents. No modern XDR product is complete without automation, and Cisco XDR has multiple automation features built in to accelerate how your SOC battles their enemies.

Response Playbooks

Having visibility from an incident is step one, but being able to quickly take meaningful response actions is vital. In Cisco XDR, the new incident manager has what we’re calling the response playbook. The response playbook is a series of suggested tasks and actions broken down into four phases (based on SANS PICERL):

• Identification – Review the incident details and confirm that a breach of policy has occurred.
• Containment – Prevent malicious resources from continuing to impact the environment.
• Eradication – Remove the malicious artifacts from the environment.
• Recovery – Validate eradication and recover or restore impacted systems.

Each of these four phases has their own tasks that guide the analyst through completing relevant steps, but the one to focus on from an automation perspective is containment. Let’s say you have a few endpoints you want to isolate but they’re managed by multiple different endpoint detection and response (EDR) products. Two are managed by Cisco Secure Endpoint and another is managed by CrowdStrike. With both of these products integrated into Cisco XDR, all you need to do is click “Select” on the “Contain Incident: Assets” task, select the endpoints to contain, and click “Execute.” We’ll handle the rest from there using an automated workflow in Cisco XDR Automation (explained in more detail in the next section). The workflow will check which endpoints are in which EDR and take the corresponding actions in each product. Improving the analyst’s ability to identify and execute a response action from within an incident is one of the many ways Cisco XDR helps your SOC accelerate its operations.

Automated Workflows

With automation being a core component of how we achieve XDR outcomes, it should come as no surprise that Cisco XDR has a fully featured automation engine built in. Cisco XDR Automation is a no-to-low code, drag-and-drop workflow editor that allows your SOC to accelerate how it investigates and responds, among other things. You can do this by importing workflows from Cisco or by writing your own. To take automation to the next level in Cisco XDR, we have a new concept called Automation Rules. These rules allow you to define criteria that determine when a workflow is executed. Here are some example rule types and when you might use them:

• Approval Task – Take response actions after an approval task is approved, or notify the team if a request is denied.
• Email – Investigate suspicious or user-reported emails as they arrive in a spam or phishing investigation mailbox.
• Incident – Enrich incidents with additional context, take automated response actions, assign to an analyst, push data to other systems like ServiceNow, and more.
• Schedule – Automate repetitive tasks like auditing configurations, collecting data, or generating reports.
• Webhook – Integrate with other systems that can call a webhook when something interesting happens. A message being sent to a bot in Webex, for example.

Cisco XDR Automation allows you to move data between systems that don’t know how to communicate with each other, use custom or third party tools to enrich incidents as they’re generated, or tailor how your analysts respond to threats based on your standard operating procedures.

APIs

Finally, the core of what powers much of Cisco XDR is its APIs. Cisco XDR has a robust set of APIs that allow you to extend most of the functionality you see in the product out to other systems. You can use Cisco XDR APIs to scrape observables from a block of text (shown below in Postman), gather intelligence from integrated products, conduct an investigation, take response actions using integrated products, and more. The flexibility to use Cisco XDR via APIs allows your SOC to customize your processes at a granular level. Want to enrich tickets in your ticketing platform with intelligence from your security products? We have APIs for that. Want to allow analysts to approve remediation actions by messaging a bot in Webex? We can do that too. Cisco XDR has a full suite of APIs that can help you take your security operations to the next level.

Conclusion

The crucial takeaway from this blog is that automation is a key component of modern security operations. The threats we face evolve constantly, move quickly, and many security teams lack enough skilled staff to monitor all of their tools. We need to use automation to keep up and get ahead of bad actors. From an industry perspective, we also recognize that many teams are trying to do more work with fewer people. Automation can help with that too. We want to enable your SOC to automate the things they don’t want to do and accelerate the tasks that truly matter. All of this and more can be done with Cisco XDR.

The Power of 5G for the Connected Future

Trains, planes, automobiles… they all move fast — their network should, too. Transportation systems depend on a strong, secure network – drivers, passengers, employees, and even autonomous operations all rely on it.

5G connectivity is key to unlocking next-gen transportation networks and applications. Given the critical importance of safety in the transportation ecosystem, in addition to ensuring a seamless user experience, having ubiquitous and extremely reliable connectivity is mission critical. Managing multi-access technologies such as public 5G, private 5G, and Wi-Fi will play a pivotal role in ensuring reliable and secure connectivity across transportation use cases.

Traditional networks forced data back to centralized nodes, which increased latency by being further way from where the data originated.  With 5G, these nodes can now be decentralized and distributed in cloud deployments, bringing applications and the internet closer to the vehicle, and allowing unprecedented low latency connectivity. Additionally, 5G provides improved security to aid car manufacturers and fleet managers to meet connected vehicle application security requirements.,

Next-gen experiences in the connected car

The connected car has evolved since the early days of sending a signal once the vehicle was in an accident.  Today’s connected vehicle has become a bidirectional communicational channel. It needs to be able to communicate with the internet, other vehicles, roadways, intersections, and more for traffic, safety and even entertainment use cases. Automotive OEMs must navigate how to seamlessly move a vehicle between environments, using multiple access technologies, and maintain network visibility, control, and reporting.

Connected cars are the most sophisticated Internet of Things (IoT) devices today with use-cases (onboard applications or services) ranging from notifying drivers of upcoming road hazards, emergency vehicles, or pedestrians in intersections, to telematics services that enable predictive maintenance of vehicle components, infotainment services to enable audio and video streaming apps (Netflix, Spotify), on-board Wi-Fi, high-definition maps, and a marketplace for retail use-cases.

In addition to these use-cases, OEMs are looking at 5G as a critical enabler for autonomous driving with V2X services – where the car communicates with neighboring vehicles, roadway infrastructure, and an edge cloud – which requires periodic mapping updates and predictive intelligence with automated assurance to detect service anomalies and drive corrective actions. Additionally, software defined vehicles require frequent software updates (FOTA/SOTA) which require reliable, high-bandwidth connectivity.

Webex integration is another application that OEMs are choosing to enable as a new service for their customers by making their vehicle a mobile connected office. Ford and Mercedes Benz AG’s recent partnerships with Cisco to enable WebEx conferencing in their vehicles pave the way for mainstream adoption by other OEMs.

Commercial Vehicle (CV) OEMs are also leading adoption of autonomous trucking (AT) technologies and building homegrown fleet management solutions. Pervasive connectivity with edge deployments supporting mission critical V2X communications is a pre-requisite for CV OEMs to embrace autonomous trucking. Platooning, considered to be the first commercial AT application, is expected to generate TCO savings of ~45% by the end of this decade. Fleet management solutions for electrified, autonomous trucks will subsequently leverage 5G connectivity for predictive diagnostics and maintenance of vehicle components and powertrain. Figure 1 has an overview of connected vehicle 5G-enhanced use-cases.

Figure 1. Connected vehicle 5G-enhanced use cases

Cisco’s vision for a 5G connected transportation future

To achieve this vision of a 5G connected future in transportation, we are enabling vehicle OEMs to take the control needed to deliver a safer and more sustainable fleet. That requires deep integration with networks and a deep understanding of the quality of service (QoS) that comes from it.

QoS becomes critical for services that depend on specific characteristics or SLAs like safety or autonomous driving. OEMs need to know how vehicles are performing, and to be able to address issues as they arise, not open a ticket with their communications service provider (CSP) and wait for a response. They need a framework where CSPs allow them certain control and configuration privileges, like applying a slice to a network service or deploying additional edge nodes when capacity dictates they are needed.

This level of control will allow OEMs to provide unique customer experiences, with a reliable QoS to deliver their services. The car becomes a digital extension of the passenger’s journey, whether it’s a privately owned vehicle, or a shared mobility service. And this goes beyond the connected car.

OEMs and municipalities must work together to build intelligent systems that will power the connected roads and corridors.  They must learn how to bring disparate sources of data together, process them into intelligent decisions and then feed that information back to drivers or infrastructure that can act upon it.

The next generation of both cars and networks will change transportation and mobile networks in ways we can’t even fathom yet. But unless you have a strategy for how to bring these two together, you will struggle to unlock the power that is just at our fingertips.

Announcing Cisco ISE 3.3

If you were at Cisco Live 2023 in Las Vegas, you surely saw that Cisco announced a lot of new products. One of these new products was the update to Cisco Identity Services Engine (ISE 3.3).

Every network admin or security operator has the same issue: you’re trying to enhance your network’s security, while adding visibility and boosting efficiency, all without sacrificing flexibility. In other words, you want more features without the complications. Cisco ISE 3.3 has that.

Split Upgrade and Multi-Factor Classification adds flexibility

When it comes to flexibility, Cisco ISE 3.3’s Split Upgrade feature will change the way you look at ISE upgrades. Customers can be hesitant to update to the newest version of Cisco ISE, because it can take a long time for ISE nodes with large databases to complete the upgrade. Split Upgrades is a new process that is less complex, as files are downloaded before upgrades and prechecks are done. Split Upgrade gives you better control on which ISE nodes to upgrade at any given time, without any downtime.

Cisco Identity Services Engine (ISE) Dashboard

Another feature in Cisco ISE 3.3 provides a way to easily identify clusters of unidentified endpoints found on the network. These endpoints are unidentified because oftentimes a variety of endpoints connect to the network that are not directly provisioned by IT. This feature uses AI/ML Profiling and multi-factor classification (MFC) to quickly identify clusters of identical unknown endpoints via a cloud-based ML engine. From there, the devices can be reviewed by proposed profiling policies via the ML engine and have the devices labeled as either MFC Hardware Manufacturer, MFC Hardware Model, MFC Operating System and MFC Endpoint Type.

By placing the unidentified device into one of these four buckets, Cisco ISE has taken a big chunk of guessing what goes where out of the equation. From there it’s easier for the customer to determine what the endpoints are and what policies should govern them when on the network.

Unique to Cisco: Wi-Fi Edge Analytics

A Cisco-only feature called Wi-Fi Edge Analytics will allow network admins to mine data from Apple, Intel and Samsung devices to better improve profiling. Cisco Catalyst 9800 wireless controllers will pass along endpoint-specific attributes, such as model, OS version, firmware, among others, to ISE via RADIUS. From there this information will be used to profile common endpoints found on the network. Network Admins will now have more data allowing them to create more defined profiles. The more information that is at the fingertips of the admin, the more precise the profile.

Even More Flexibility with Controlled Application Restart

To increase efficiency, predictability and reduce downtime, Cisco ISE 3.3 offers Controlled Application Restart. It benefits customers by saving them time and eliminating a lot of the headaches that come with managing ISE admin certificates. Customers are now given the ability to control the replacement of the ISE administrative certificate allowing them the ability to plan for maintenance once their current certificate expires. Prior to this new feature, a certification replacement required a complete reboot of all the PSNs in the deployment without the ability to know or control the order to the reboot, which can cause some admins to allow the certification to lapse.

Changes to certificates require a restart since it affects systemwide configuration and cannot be done during operational hours since it requires significant downtime. However, Cisco ISE 3.3 now provides flexibility for these certifications to be scheduled the restart at the network admins’ convenience; during the middle of the night or on weekend when network usage is low. This eliminates the need for that downtime and helps to smooth security updates without disruption.

Controlled Application Restart is a response to an industry trend where customers are moving to a short-term certificate due to added security. This new feature is beneficial as the maintenance needed to update the certification—which can take upwards of 30 minutes per certificate—can be scheduled for the middle of the night, when network use is low, saving both time and resources.

Improved Insights with pxGrid Direct Visibility

pxGrid Direct Visibility has improved visibility from the last iteration of Cisco ISE (ISE 3.2) and now customers get improved endpoint attributes via external databases such as Service Now. These attributes can now be shown in Context Visibility. Whether the data comes from endpoints, users, devices or which apps are running over the network and its different attributes, it provides a lot of information such as the device type, device owner and other things like whether the device is operational.

Getting this endpoint data in an easily accessible fashion allows you to make better network decisions based on facts. This data can then be spun to run the network in a more efficient manner allowing for a safer network and less time spent on translating information.

Tougher Security with the TPM Chip

The new TPM Chip (for supported hardware) is a response to the need for increased security. Found on the new SNS-3700 models and in some virtual environments (in a form of Virtual TPM), the TPM chip is a dedicated chip where sensitive information can be stored. Previously if Cisco ISE used a password to connect to a database, it was stored in the file system, which is less secure. But now with the information housed on the physical TPM Chip, and with the ability to create true random numbers for key generation, it has proven to be more difficult to access thus providing a more secure place for information to be stored.

With the number of new features and functionality that comes to you with the latest Cisco ISE 3.3 update, your network’s security will be enhanced, and you will notice an increase in efficiency and visibility.
