Carrier-Grade Network Management Extensions to the SDN Framework
The concept of Software-Defined Networking (SDN) recently gained huge momentum in the industry, driven mainly by IT companies interested in datacenter applications. In this paper, however, the authors consider SDN applied in the carrier domain, which poses additional requirements on the network architecture, including network management functions. They derive concrete requirements for the use-case of a virtualized multi-provider access/aggregation network based on carrier-grade SDN. They then provide initial architectural considerations for integration of network management extensions to the SDN framework as defined by the Open Networking Foundation (ONF).
