Abstract:
Abstract— Network Function Virtualization (NFV) will change the way Telecom Service providers (TSPs) have been using network functions on the proprietary hardware for various telecom and networking services. Virtualization of network functions has provided many benefits to Telecom Service Providers (TSP). While NFV has bought numerous benefits to the TSP in terms of speed of deployment, flexibility and cost reduction, the additional virtual layers introduced directly impacts the reliability, resiliency and fault management. These include, but are not limited to, Latency between Virtual Machine (VM), Latency between Network Function Virtualization Infrastructure (NFVI) nodes, Network Interface Card (NIC) availability, and Processor availability. This paper outlines and summarizes the challenges regarding reliability, resiliency and fault management in the carrier-grade NFV environment and discusses various models and features of reliability, resiliency and fault management needed to deploy a Virtual Network Function (VNF) in the service provider environment.
