In the past several months, we have presented several talks and blog posts about the importance of network programmability for configuration management of VNFs in an NFV environment. This month we are releasing a new whitepaper “Trends in NFV Management,” which takes an in-depth look at this topic. The whitepaper examines some of the new configuration management challenges of NFV, the limitations of traditional configuration management techniques, and why network programmability becomes even more important for implementing automation in the world of NFV.
The promise of Network Functions Virtualization (NFV) is to help provide a wide-range of benefits from lower operating costs to faster time-to-revenue. However, all of these depend on a core assumption: that the provisioning of Virtual Network Functions (VNFs) can be automated through straightforward management and configuration processes. In theory, this is not controversial. In practice, it can still be elusive. Network Element Providers (NEPs) need to leverage NETCONF and YANG to introduce a more standardized Application Programming Interface (API) into their network elements and unlock the value of full NFV automation.
As programmability becomes the bridge to automate NFV provisioning, it is important to understand what network programmability offers, what an API is in the context of network programmability, and the importance of standards-based APIs. Ultimately, you will learn how critical NETCONF and YANG are to achieving true network programmability using a standards-based API.
