Eliminate Network Blind Spots with Visibility from Cisco Nexus 9000 Switches and ThousandEyes

Your organization depends on your network. As networks become more and more complex, the question arises: How do you know what the network is really doing?

Today’s data centers can extend far beyond their on-premises physical location. Data and applications can be with a co-location provider or across multiple cloud providers. For many organizations, data is distributed all around the globe in a web of micro-services and containers and, consequently, outside direct view and control.

With this wide variation of locations, the deployment of Cisco Nexus 9000 switches varies as well. They might provide a Data Center Interconnect (DCI), Cloud to Cloud Connectivity, or external connectivity to sites on the Internet. However, across this vast variation in deployment use-cases, one thing is common—there can be blind spots!

Consider that, whether for the Internet, Cloud Connectivity or Data Center Interconnect, the transport infrastructure is often provided by an external entity. This external entity, either a Service Provider or your Backbone team, more than likely doesn’t give you operational access and visibility into what some might call the “sausage making” of networking. And that limits visibility and therefore control.

Gaining Deeper Visibility

Visibility into transport infrastructure is essential to optimize the efficient and reliable management of the network. Deeper visibility provides key performance indicators (KPI) such as throughput, path information, latency, jitter, and loss. This information assists in rapidly detecting and remediating transient network degradations—those that can only be detected with continuous monitoring of KPIs over time. Even more importantly, recording this data effectively provides visibility back in time to not just mitigate issues, but to identify and correlate their root causes so they can be eliminated before they reoccur.

In the past, IT used a variety of approaches to attempt to collect actionable KPI data. For example:

◉ Placing compute resources in a co-location for the purpose of collecting telemetry data

◉ Connecting a server outside the DMZ for the purpose of measuring performance

◉ Adding a collector to the DCI to provide visibility

Figure 1. A Server Used as a Telemetry Sensor

However, as Figure 1 shows, they might not be in the exact data path through which all traffic will pass. Also, using passive data collection does not provide critical visibility into the network paths that data traverses.

Integration with a ThousandEyes

In August 2020, Cisco completed the acquisition of ThousandEyes, an Internet and cloud intelligence platform capable of expanding visibility into, and delivering insights about, the digital delivery of applications and services over the Internet and the cloud. With Cisco’s strong Cloud and Data Center network portfolio, the integration of the ThousandEyes vantage points into the Nexus 9000 enables unprecedented visibility through ThousandEyes from Nexus 9000 switches.

Instead of placing additional compute resources in co-locations, connecting them outside your DMZ, or adding them to your DCI, you can install ThousandEyes Enterprise Agents on Cisco Nexus 9000 switches. The agents measure across the exact paths that data passes gathering crucial KPIs wherever a Cisco Nexus 9000 is present (see Figure 2).

Figure 2. Cisco Nexus 9000 hosting ThousandEyes Enterprise Agent

ThousandEyes and Nexus 9000 Integration Details

The Cisco Nexus 9000, in ACI or NX-OS mode, provides a hosting environment embedded in the switch’s Network Operating System (NOS) itself. Within NX-OS is a dedicated and secured Linux Container (sLXC) environment for the ThousandEyes Enterprise Agent called Guest-Shell. The agent is hosted in the sLXC and can access the switch’s bridging and routing tables for all its reachability needs. As communication to and from the agent resides in the Nexus 9000 itself, Control Plane Policing (CoPP) can enforce the allowed data-rate for additional protection. Figure 3 shows a schematic diagram of the ThousandEyes Enterprise Agent in a Cisco Nexus 9000 with NX-OS.

Figure 3. ThousandEyes Enterprise Agent hosting in Cisco Nexus 9000 (NX-OS)

Scalability, of course, is a key consideration. With tens, hundreds, or even thousands of switches in a network, simplified agent lifecycle management is crucial. While the ThousandEyes Enterprise Agent can be manually installed into the NX-OS Guest-Shell, the Cisco Nexus Dashboard Fabric Controller (NDFC) provides an integrated workflow to activate the functionality with a single click (see Figure 4).

Figure 4. Agent Install on Cisco Nexus 9000 (NX-OS)

The automated install/uninstall in NDFC, provides all necessary configuration settings so the latest version of the ThousandEyes Enterprise Agent can be directly downloaded from the Cisco Repository. Furthermore, the agent will also be automatically onboarded to the ThousandEyes Dashboard for the Test Setup phase of deployment. While Cisco NDFC provides unified configuration and installation of agents, you can still choose to use other tools such as Ansible Playbooks to perform these tasks.

Better Together for Deep Visibility

Operating a data center network requires a versatile and flexible approach to management with deep visibility into the network, including transport infrastructure. The deep linking and integration of Data Center Interconnect (inter-DC) visibility (ThousandEyes) with data center infrastructure (Cisco Nexus 9000) provides access to the KPIs needed to measure performance, quickly detect and resolve network issues, and correlate root causes to eliminate issues in the future.

Cisco continues to integrate new capabilities into Cisco Nexus Dashboard to provide a granular view into the many corners of the extended enterprise network. Today Nexus Dashboard has deepening integrations with Nexus 9000 switches, Cisco Insights, App Dynamics, and of course ThousandEyes, to improve end-to-end visibility from data center, to cloud, to applications and the workforce. With Cisco Nexus Dashboard as a single-point of control for visibility and insights, IT has the ability to foresee and mitigate many of the potential issues that impact the workforce and business operations before they become impediments to progress and profits. And so, the journey continues…

Using Infrastructure as Code to deploy F5 Application Delivery and Cisco ACI Service Chaining

Every data center is built to host applications and provide the required infrastructure for the applications to run, communicate with each other, be accessed by their users from anywhere, and scale on demand.

To achieve this, your data center network must be able to provide different types of connectivity to different applications. This includes east-west connectivity between application tiers, as well as north-south connectivity between users and applications. Both rely on additional application delivery Layer 4 to Layer 7 services like load balancers and web application firewalls.

Cisco ACI and F5 BIG-IP Service Insertion

Cisco ACI’s powerful L4-L7 services redirection capabilities will allow you to insert services and redirect traffic from the source to the destination anywhere in your fabric without needing to change any of the existing cabling. This is where you can insert F5 BIG-IP load balancer, to provide application availability, access control, and security.

Read More: 500-440: Designing Cisco Unified Contact Center Enterprise (UCCED)

This is possible using the Policy Based Redirection (PBR) capabilities of the Cisco ACI fabric by configuring a Service Graph in APIC.

But PBR policy and Service Graphs entail a series of manual configurations. This can be tedious, error prone, and inefficient especially if the same configuration happens very often. On top of that, the configuration of the BIG-IP service itself requires information from the Cisco ACI Service Graph.

Simplified Service Insertion with Cisco and F5

This is why Cisco partnered with F5—a leader in the application delivery and web application firewall space around the Cisco ACI and the F5 BIGIP solutions—to simplify the deployment of F5-powered L4-L7 services using the F5 ACI ServiceCenter App for APIC.

This integration simplifies management of Virtual sever configuration on F5 BIG-IP and Service Graph configuration on Cisco ACI by providing a simple user-friendly UI.

In this blog, we will discuss an evolution of this integration for customers looking at Infrastructure as Code as the means to automatically deploy both Cisco ACI network infrastructure configuration and BIG-IP L4-L7 services for their applications and looking for opportunities to start progressing in their IaC journey.

End-to-End Service Insertion Automation with Infrastructure as Code

As a reminder, Infrastructure as Code is a journey that you can embark at different stages depending on your existing automation knowledge and needs. The goal of this journey is to translate manual tasks into reusable, robust distributable code and apply software development techniques such as version control (git), automated testing and CI/CD to achieve those goals.

The first step in an Infrastructure as Code journey is to start by selecting a language or a toolset to express our intent for our Infrastructure as actual code. For this integration, we decided to join forces with HashiCorp, the leader in infrastructure automation and a shared partner of Cisco and F5 and chose HashiCorp Terraform as the Infrastructure provisioning tool and using HCL (HashiCorp Configuration Language) to define service configuration as our code.

F5 and Cisco both have verified HashiCorp Terraform providers, making it easy to create the needed configuration on both sides using HCL (HashiCorp Configuration Language) as our code.

To further simplify automation of the numerous configuration items, Cisco and F5 have worked together on a set of Terraform modules which provide best practices defaults for most of the configuration items and allow users to override specific items of the configuration.

By providing a single workflow, all the dependencies are taken care of, and the usage of the overall solution is simplified. Modules also defines outputs that can be passed from one module to the next and modules can depend on each other to represent the dependency relationship they have with each other.

As part of this solution, a simple workflow with 3 Terraform modules has been created:

◉ The Cisco ACI Service Graph Terraform module allow the user to create and deploy a complete service graph for Policy-Based Redirection (PBR) with the required bridge domains and other necessary constructs as documented in the Cisco ACI Policy-Based Redirect Service Graph Design white paper

◉ The F5 BIG IP VLAN Self IP Terraform module configures the interfaces of the BIG-IP (physical or virtual) facing the ACI fabric with the correct VLANs, and Self-Ips configuration.

◉ The F5 BIG IP AS3 HTTP Service Terraform module configures an HTTP Service using F5 Application Services 3 extension (AS3) to provide a load balancing function with a specific Virtual server (VIP) and the recommended configuration when used in conjunction with Cisco ACI PBR.

Instantiation of the modules allows the user to pass the parameters necessary and use default parameters for the rest of the configuration hiding all their internal complexity to the user. The following is an example of the instantiation of the different modules and their dependencies:

module "cisco-aci-service-graph" {

    source = "./modules/service-graph-lb-pbr"

    tenant              = var.aci_tenant

    vmm_provider_dn     = var.aci_vmm_provider_dn

    vmm_domain_name     = var.aci_vmm_domain_name

    vmm_controller_name = var.aci_vmm_controller_name

    vm_name             = var.aci_bigip_vm_name

    vnic                = var.aci_bigip_vnic

    device_name         = var.aci_bigip_device_name

    device_mac_address  = var.aci_bigip_provider_mac

    device_ip_address   = var.selfip_int

    provider_bd_subnets         = var.aci_provider_bd_subnets

    consumer_bd_subnets         = var.aci_consumer_bd_subnets

    provider_service_bd_subnets = var.aci_provider_service_bd_subnets

    consumer_service_bd_subnets = var.aci_consumer_service_bd_subnets

}

module "bigip_vlan_selfip" {

    source       = "./modules/vlan_selfip"

    vlan_int_tag = replace(module. cisco-aci-service-graph.internal_vlan, "vlan-", "")

    vlan_ext_tag = replace(module. cisco-aci-service-graph.external_vlan, "vlan-", "")

    selfip_int   = var.selfip_int

    selfip_ext   = var.selfip_ext

}

module "as3_http_app" {

    source      = "./modules/as3http"

    server1     = var.server1

    server2     = var.server2

    vip_address = var.vip_address

    snat        = var.snat

}

You can see that the “bigip_vlan_selfip” module uses the output of the cisco-aci-service-graph module to pass the VLAN automatically derived from the ACI VMM domain integration. This removes the need to statically define a VLAN and allow the reuse of this plan over and over. You can also see that the module definition uses a lot of variables creating a reusable piece of code that can be instantiated multiple times with different sets of variables.

With this joint solution, deploying BIG-IP application services on an ACI network infrastructure with a Terraform workflow and applying Infrastructure as Code principles, can greatly simplify, automate, optimizes, and accelerate the entire application deployment lifecycle in turn improving time to value.

To better collaborate with other members of your organization on provisioning this solution, HashiCorp Terraform Cloud can be used to provide remote state storage allowing your state file (which provides a system of record for what you have provisioned) to be stored securely and remotely.

Redefining the Cost Models for APAC Broadband Operators

In a market approaching 5.7 billion mobile subscriptions in 2021, broadband can sometimes feel to play second fiddle in Asia & Oceania (Omdia). However, 670 million broadband subscriptions are nothing to be sniffed at – especially in a region with hundreds of millions more underserved or unserved at all.

The global pandemic only exacerbated the need for high-quality fixed broadband services. For consumers, this was driven by the need to access digital healthcare, education, and entertainment services – in 2020 alone Omdia calculates Asia and Oceania OTT video subscriptions rose by 22 percent to more than 550 million. For service providers, the massive rise in this video and digital content traffic means they need more scalable broadband networks to deliver the best broadband services and to better supplement mobile networks which are also under strain from rises in data-intensive video and digital services. Operators also need their infrastructure deployments to be more cost-efficient to connect the millions still to be connected in the Asia & Oceania region.

The Asia & Oceania broadband subscribers are generally concentrated in high broadband penetration markets like China, Japan, & South Korea, but there is plenty of potential in low penetration countries like India & Indonesia with broadband penetration rates below 20%.

This pressure on operators to build out and improve the operations of their broadband networks comes at a time when they are moving towards distributed and cloud-native network architectures, as part of the latest iteration of Network Functions Virtualization (NFV) and software-defined networking (SDN). The development of these technologies was originally focused on core network functions, but are now becoming more common closer to the edge.

One such development is in Broadband Network Gateways (BNGs). Traditionally BNGs have been hardware-centric solutions, appliances with tightly coupled hardware and software. If operators needed to scale a deployment they would deploy more BNG appliances. To keep up with anticipated demand this model necessitates service providers to plan and deploy BNG nodes months or years in advance of expected demand.

Cloud-native BNG solutions promise to change these cost dynamics in two key ways:

◉ Disaggregation of hardware from software

   ◉ Provided operators have the deployed hardware infrastructure in place they can spin up BNG software licenses as required to meet demand, reducing upfront investment costs, and time to revenue for BNG solutions.

   ◉ There is the potential to re-purpose existing BNG hardware appliances or use commoditized hardware to maximize existing BNG investments, rather than having to rip & replace all existing hardware.

◉ Implementation of Control /User Plane Separation (CUPS) architecture

   ◉ This allows operators to simplify BNG configuration by only configuring a handful of BNG control plane nodes to manage the potentially 100s of BNG user plane BNG nodes that make up the network.

   ◉ This leads to greater levels of network automation, supporting streamlined OPEX, and greater levels of network optimization to provide a better quality of service for end-users.

Figure 2 shows an example of what a cloud-native BNG solution deployment could look like. From these changes in cost dynamics, Omdia believe there is scope for total cost of ownership (TCO) savings vs traditional deployment models in the region of 10-30% over a five-year period.

To achieve these savings operators do need to prioritize investment in supporting skillsets to manage and automate cloud-native BNG solutions. These investments will in time make a clear difference to the deployments themselves and the wider business as operators look to orchestrate and automate cloud-native network solutions across network domains. Telenor is an example of an operator who is beginning to reap the benefits of broad skillset and organizational investment in the context of their network transformations. In 2019 Telenor reskilled approximately 6.4% of its employees, investing in virtualization, cloud, automation, and other adjacent technical skillsets. This supported an OpEx decrease of 7% YoY on a constant currency basis in 2020 (excluding figures from Telenor’s acquisition of Finland’s DNA).

The Omdia “Evolution of the BNG in Asia and Oceania” white paper focuses on the changing nature of BNG solutions and what they mean for operator cost models and the ability to develop services to support new revenue streams.
