                Resource Management in Service Chaining
         draft-irtf-nfvrg-resource-management-service-chain-02

Abstract

   This document specifies problem definition and use cases of NFV
   resource management in service chaining for path optimization,
   traffic optimization, failover, load balancing, etc.  It further
   describes design considerations and relevant framework for the
   resource management capability that dynamically creates and updates
   network forwarding paths (NFPs) considering resource constraints of
   NFV infrastructure.
