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.”  

5 areas OpenStack needs help to support NFV

By: Andreas Lemke, Marketing Lead, CloudBand NFV platform, Alcatel-Lucent
From original Alcatel-Lucent TechZine posting

OpenStack isn’t an as-is solution for telco network functions virtualization (NFV) infrastructures. OpenStack is an open-source cloud management technology that provides many of the capabilities needed in any NFV environment. And this has prompted interest among many telco service providers.

But to realize the full benefits of NFV, service providers need NFV platforms that provide additional capabilities to support distributed clouds, enhanced network control, lifecycle management, and high performance data planes.

Can the vEPC be deployed in the LTE consumer network?

By: Keith Allan, Director IP Mobile Core Product Strategy, Alcatel-Lucent

This article discusses the progress in the development and operational management of the vEPC to support the LTE consumer network. It answers the question: Is the vEPC commercially viable in large-scale, LTE network deployments? At Mobile World Congress 2015, Alcatel-Lucent will show a live demonstration of vEPC dynamic scaling together with simplified NFV management and orchestration.

Over the past several years, I’ve met with many mobile network operators (MNOs) and discussed their plans for virtualizing the evolved packet core (EPC). It’s clear from the more recent conversations that MNOs are now convinced that the vEPC is both financially and technically viable for their networks.  But is the vEPC ready for the MNO’s LTE consumer network?  In this article, I’ll discuss why I now think that’s possible.

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.
