• 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
