Hi all ,
Thanks very much for listening to my presentation during the London meeting and
providing feedback on the draft.
Based on the feedback received , I have re-written the draft as two drafts.
1) DPS-Requirements Draft :- (draft-arumuganainar-rtgwg-dps-requirements-00.txt
)
- This talks about problem statement , full requirements and general
framework for DPS
- I have also included existing implementation and Gap analysis
2) DPS Use cases :- (draft-arumuganainar-rtgwg-dps-use-cases-00)
- Document all the use cases for DPS
- Majority of the use cases taken from existing implementation. I have
also included one use case that currently on our roadmap
- As discussed draft can be amended if readers can come up with
additional uses case.
Since requirements and Use cases draft essentially covers everything , my
original draft(draft-aumuganainar-rtgwg-dps-00 ) do not hold any relevance.
Hence I have allowed my original draft to expire.
In addition to this I have also posted one more draft. In the current
implementation, signalling happens at control plane and hence DPS behaviour do
not changes when there are changes in network condition . For example DPS
behaviour when there is acute congestion on the primary link will be same as
when there is no congestion. This is because BGP is used for signalling . And
BGP is a control plane protocol. It do not have any information about what is
happening in the forwarding plane.
If we can move the signalling to forwarding plane then probably we can tune
the DPS behaviour to adapt to dynamic network conditions. I have documented
this requirement in a separate draft. This draft proposes to do the signalling
at the TCP layer . It would be great if you can review this draft as well
(draft-arumuganainar-rtgwg-dps-l4-ppn-00 ) .
It would be great if you can review this for me and let me know if there are
any feedback or comments.
Thanks and Regards

Subject: Requesting Comments about the Draft : draft-aumuganainar-rtgwg-dps-00
Hello all,
I have posted a following draft - Dynamic Path selection ( Based on Application
). http://www.ietf.org/internet-drafts/draft-aumuganainar-rtgwg-dps-00.txt
In the draft I have proposed a network design architecture for routing packets
via different paths available in the network based on application port number.
Primarily, this is targeted for Enterprise customers who have built up
redundancy at their WAN edge but are suffering from a congested primary link
whilst the secondary is idle.
The objective of this architecture is as follows
1) Offload bulky application on to the secondary link
2) Achieve the above without introducing asymmetric routing in the network
It would be great if you can review this draft and respond back with any
comments.
Thanks very much.
Thanks and Regards
