Cisco Orchestrated Assurance Powered by Netrounds

Automated Verification of Network Service Quality

What if you could automatically verify that each provisioned service works when delivered and continues to work throughout its lifetime?

Netrounds’ active test and monitoring capabilities, orchestrated and fully automated through Cisco® Network Services Orchestrator (NSO), help enable you to improve customer experience and ensure that provisioned services are delivered as promised.



Cisco NSO has just configured a new service. Does it work across all network layers and domains? Will it continue to work throughout its lifetime?

Many times, end-to-end services depend on network components not configured by NSO. In addition to device configuration, dynamic behavior such as varying network load can also influence service quality. Netrounds helps you actively verify that a provisioned service works at the time of deployment, before your customers begin using the service.

After successful verification of service provisioning, Netrounds provides continuous service quality insight from your customers’ viewpoint. This insight helps you to discover issues earlier and resolve them faster.

Netrounds provides out-of-the-box capabilities to actively test and monitor performance metrics for Layer 2 and 3 connections, as well as voice, video, and data services.

NSO automatically drives all active test and monitoring activities when the service is provisioned through Netrounds’ NETCONF and YANG API.


  • Actively verify that services work after they are provisioned by Cisco® Network Services Orchestrator (NSO). Generate real-world traffic to help ensure that services are delivered correctly before they are exposed to end-users and deliver birth certificates to key stakeholders.
  • Help ensure that provisioned services continue to work throughout their lifetime. Get service quality insights from the end-user perspective through active, real-time measurements.
  • Resolve problems faster. Take advantage of remote testing capabilities; automate advanced test scenarios through Cisco NSO; and test across layers, services, and domains.
  • Reduce manual and field test efforts. Automate test sequences and use remote troubleshooting to reduce manual field efforts, dispatching technicians to fix problems, not to find them.
  • Get started easily today. Netrounds’ components are easily installed and interwork with the network devices already deployed in your network. In addition, Cisco NSO has a prebuilt integration module to enable full Netrounds automation.


Deliver High-Quality Services Right the First Time

Customers expect immediate and flawless service turn-up. This expectation creates high demands to deliver the service “right the first time.” To achieve this goal of agile, assured service creation and delivery, active testing must be an integral part of the service provisioning process.

Today’s bandwidth- and media-intensive services also require a consistently high level of quality. An inability to monitor and assure end-to-end service quality from the end-user’s perspective will lead to customer dissatisfaction and churn. Active, multilayer monitoring is required to gain real-time insights into service quality.

CSPs will need an extremely efficient and economical operational model; a model that provides business agility, enabling CSPs to instantiate and tear down new services on demand and in near real time. Automation will make this vision a reality.

Anil Rao, Senior Analyst, Analysys Mason, from Automated Service Assurance Is Critical for Operationalizing NFV/SDN: Active Testing Automation Presents an Early Opportunity

Solve Current Operational Issues

Testing and monitoring from an end-user perspective using traditional, resource-focused assurance solutions is practically impossible as the connection between the network resources and the service consumed by the end-user cannot be accurately defined. Active tests across network and service layers, from the right network location, is the only way to understand the end-to-end service quality your customer is experiencing. In addition, introducing software-based active testing does not require an overhaul of your entire network and management systems or additional infrastructure investments.


Evolve with Complex and Dynamic Service Topologies

Services are now evolving towards a mix of virtual network functions in datacenters together with physical networking elements. These services are often delivered over-the-top with a high rate of change resulting from self-service portals and automation loops.

In this dynamic environment, traditional assurance solutions do not have the agility to keep up - attempting to interpret end-to-end service quality based on passive resource and infrastructure monitoring status will not be successful.


The Importance of a True Real-time View of Your Customer’s End-to-End Service

Service providers looking for winning strategies should focus on the services that customers have bought instead of infrastructure faults and performance monitoring (PM) data pulled from network resources. A comprehensive view of the end-to-end service that you are delivering requires activation testing upon delivery and continuous monitoring from your customer’s perspective.

How do you ensure the service you are delivering is meeting the quality that the customer expects?

What You Get

The Cisco Orchestrated Assurance solution powered by Netrounds includes two main Netrounds components (Figure 1):

  • Netrounds Control Center with relevant feature packs
  • Netrounds Test Agents with active traffic-generation capabilities

Figure 1. Netrounds Components

Netrounds Control Center provides a graphical designer environment for developers to build activation testing templates and other automatable test sequences. NSO triggers these templates using the NETCONF and YANG API to achieve closed-loop automation. The Netrounds Control Center GUI environment also presents test reports and real-time key performance indicators (KPIs) of actual end-user experience through dashboards and drill-down charts.

All testing and monitoring activities are performed using traffic-generating Netrounds Test Agents remotely located at strategic locations in your network.

To automate and orchestrate testing and monitoring through Netrounds Control Center using NSO, you use a prebuilt network element driver (NED) for NSO. In addition, you can dynamically deploy Netrounds Test Agents on virtualized compute hosts by extending NSO with the Network Functions Virtualization Orchestrator (NFVO) Core Function Pack.

Netrounds Test Agent Main Features

Netrounds Test Agents are software based and run as virtual machines on common hypervisors or directly on x86 bare-metal devices, such as Cisco Unified Computing System™ (Cisco UCS®) servers. For full automation, NSO can dynamically deploy Test Agents in these virtual environments at the time of service configuration.

Test Agents actively generate authentic traffic and analyze detailed, real-time measurements across multiple applications, services, and interfaces. Test Agents support concurrent measurement of network performance (UDP, TCP, Y.1731, and TWAMP), IPTV and OTT video, and the Internet (HTTP, ping, and Speedtest), as well as VoIP and Session Initiation Protocol (SIP) telephony.

All Test Agents are centrally managed and updated from the Netrounds Control Center using an automated call-home mechanism.

Integration with Cisco NSO: Simplified Example

Netrounds integration with NSO is simple using the prebuilt NETCONF and YANG driver to the Netrounds Control Center (Figure 5).

Figure 5. Simple Example of Netrounds and Cisco NSO Integration

The example starts with NSO receiving a service order (1). NSO then configures the devices and enables built-in test functions such as TWAMP and Y.1731 (2). NSO could optionally deploy Test Agents as Virtual Test Agent (vTA) virtual network functions (VNFs). After the service is provisioned, NSO asks the Netrounds Control Center to perform an activation test to verify that the service is working (3). This is done by using pre-deployed and shared Netrounds Test Agents sending active traffic and reporting test metrics back to the Netrounds Control Center (4), which provides a pass-or-fail outcome of the activation test to NSO (5). A passed test is required to hand over the service to the customer, whereas a failed test would require reconfiguration. A comprehensive report of the test results (6) and a real-time visualization of service quality (7) are made available in the Netrounds Control Center dashboard. As a next step, NSO could automatically trigger the Virtual Test Agents (vTAs) to begin active monitoring of the end-to-end service following successful service activation.

Table 2 provides some common use cases for the Netrounds and NSO solution.

Automation, Agility, and Assured Network Deliveries

TM Forum’s “Orchestration: Get Ready for the Platform Revolution” study reported that the main reason that service providers choose to automate their networks through orchestration is to increase agility. Seventy-five percent of all survey respondents ranked the capability to deliver services to customers more quickly in their top three reasons.

In a recent Netrounds customer survey, Netrounds’ service provider users reported that:

  • They can introduce new, assured services at least 20 percent faster using Netrounds automated service activation testing than using manual methods.
  • Customer frustration has decreased approximately 25 percent since their organization began using Netrounds.

Not only is the delivery of assured network services improved. Netrounds users also report that the number-one process significantly improved by using Netrounds is troubleshooting.

  • Eighty-four percent of respondents report that Netrounds helps them resolve network issues faster.
  • On average, Netrounds users can find and fix network issues 32 percent faster using Netrounds than using other troubleshooting tools and methods.

Service providers use Netrounds’ remote testing capabilities and automate advanced test scenarios through NSO, further reducing time to delivery of assured network services and improving visibility into network health for proactive problem resolution.


Global System Integrator Helps Ensure Diverse VPN Deliveries with a Single, Flexible Solution

Challenge: A global system integrator requires a versatile service activation testing solution to help ensure that the varied VPN services that the integrator is delivering meet the service quality SLAs and metrics promised.

Today, the integrator is delivering three types of VPN services:

  • Traditional MPLS-based Layer 3 VPN services on traditional customer-premises equipment (CPE)
  • Software-defined WAN (SD-WAN) Layer 3 VPNs on container or standard x86 CPE
  • Orchestrated SD-WAN or MPLS-based Layer 3 virtual VPN services on virtual CPE (vCPE)

Solution: The global system integrator chose Netrounds to tackle verification of VPN service deliveries for all these environments: physical, hybrid, orchestrated and virtual networks. The system integrator:

  • Verified each VPN delivery and created birth certificates prior to handing over services to customers
  • Used active monitoring from Netrounds when managing customer networks after initial delivery, allowing the integrator to receive alarms if service quality degraded and to find and fix problems proactively
