Paper Identifies the Need for DevOps, New KPIs for Virtualized Environments

By Paula Bernier November 04, 2015

Nexius and The University of Texas at Dallas have developed key performance indicators that they say are bettered suited to the dynamic virtualized network that companies are now exploring implementing. The companies lay out those indicators in a new report called “Organizational Collaboration and New KPIs for NFV Success.”

“A much greater scale of configuration is needed to deploy the [virtualized] resource from scratch onto commodity hardware pools, as compared with the more subtle configuration changes of physical network elements in ad/remove service actions,” the paper notes. “Therefore, it is important to monitor metrics such as the number of times VMs are migrated between physical servers, time to discover an application or resource, and the time and compliance with complex application licenses required to deploy a function and its associated middleware, operating system and hypervisor.”

The partners suggest that operators should continue to classify network operations functions and KPIs using the International Standards Organization FCAPS framework, but with new metrics suited to NFV. They go on to say that change management functions should have infrastructure compatibility metrics, the network provisioning should have KPIs relative to software release cycle frequency, and that resource initialization should measure mean time to instantiate VNF.

The paper also talks about the importance of DevOps and the need to establish a framework for defining new KPIs. It also offers up a virtual DVR use case that Nexius and The University of Texas at Dallas say illustrates how a cable provider is employing these new KPIs.

As the partners note in the paper, network operators are embracing virtualized infrastructure to lower their costs and roll out new services and features more quickly in what has become an environment of shrinking margins. To make this transition a successful one, they go on to say, network operators should adopt the DevOps model, in which software development and network operations are tightly coupled, and introduce new KPIs, as discussed above.
