• An architecture designed with SDN in mind

• Applications finally control the network in

a scalable way

• Completely Standards-based/Open

Approach (IETF)

• Right balance between distributed

intelligence & centralised optimization

• IP architecture for the next 5/10 years –

option for NG-DC! Source Routing: the source chooses a path and

encodes instructions in each and every packet
