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


4
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 Offload
Orchestration 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:

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
 NfV is an endgame which is
enabled by SDN.
 NfV needs cloud
management stuff – and
more.
 Network & Application
aware orchestration.
