How to meet the challenges of virtual network functions assurance

By: Kevin Landry, Product Marketing Manager, Alcatel-Lucent

As they move into the cloud era, network operators need a service aware network operations tool to assure virtual network functions (VNF) management. They’ll need it to efficiently perform a variety of network operations tasks, including:

  • Service impact assessment
  • Fault localization
  • Identification of true root-cause (from symptomatic faults)
  • Taking corrective actions to resolve problems fast

As described in a vEPC post related to converging NMS and VNF manager functions within the ETSI Management and Orchestration (MANO) architecture, operators need to evolve their network operations tools for NFV through tighter coupling the NMS and VNF manager functions. Specifically for VNF assurance, the blog states “Troubleshooting is simplified because traditional NMS faults/events are correlated with VNF related events/faults. The VNFM provides lifecycle management and automates the self-healing of VNFs.”  

Answering the Question of How to Manage NFV Effectively with an vEPC

By: Mae Kowalke, TMCnet Contributor

The advantages to mobile operators of network functions virtualization (NFV) and moving to a virtualized evolved packet core (vEPC) have become clear, and mobile networks operators are pretty much sold on the technology in theory.

As the technology side has been figured out and operators begin to plan commercial deployments of NFV and vEPC, however, discussion is starting to move toward operational requirements and challenges. Mobile network operators need to figure out how best to manage these new virtual network functions (VNFs) and the NFV infrastructure, and also how to modify the existing network operations model when these VNFs are deployed.
