L3 Router Offload Service Orchestration Use Case Internet edge Offload
Extending the life of edge interfaces by keeping intra-metro traffic in the metro
Data Centre Gateway optimization Selective routing of inter-DC traffic before traffic hits the DC
gateway. Provide fine-grained control of traffic flows to support low
latency/cost DC interconnect

L3 Router OffloadOrchestration Requirements OpenFlow used for south-bound control to keep the
solution open & flexible. Dynamic OpenFlow methodology used to discover
offload physical topology. SDN controller talks BGP to learn logical topology. Mapping between existing and new offload topology
configured via API. Policy-Based Offload:
Traffic analysis determines candidate routes for offload L3 switch FIB limiting factor in solution scalability

Data Center Interconnect (DCI) Scenario Virtualization has made compute all singing and
dancing Network aren’t currently as agile
Lack of orchestration mandates too much or not enough…

NfV is an endgame which is enabled by SDN.
NfV needs cloud management stuff – and more.
