Hi,

Dynamic path selections draft is well written to have application based flexibility in the routing.

Seek clarification on following


-          Application based traffic offload/routing requirement most often comes from enterprise segment, never seen from service providers.
Since BGP is proposed in the draft to achieve application based routing but BGP is most often used between Autonomous systems (between Service providers and Enterprise and Service Providers), Why widely accepted and deployed IGPs (OSPF and EIGRP) cannot work to achieve proposed functionality? If IGPs are supported to have application based routing it will great value add for large Enterprises segment without any major change in existing routing.


-          Draft proposes static configuration to define application profile, how to achieve the routing for the applications dynamic in nature and use dynamic port numbers etc. ?
