[RFE] bgp-dragent-hosting-multiple-speakers

[vikram.choudhary]

[Existing problem]
The number of BGP speakers a BGP driver can host may vary. For instance Ryu can support only 1 BGP Speaker while Quagga can host multiple. In the current BGP dynamic routing implementation [1]_, the BGP DrAgent and DrScheduler cannot adjust themselves as per the driver support which might be required for effective scheduling.

[Proposal]
There could be 2 ways for achieving this:
1. Admin can hard code the support information in the configuration file and the same could be read by BGP DrAgent and DrScheduler during start-up.
2. New interface can be exposed by BGP DrAgent to DrScheduler using which DrScheduler retrieve this information during start-up.

[Benefits]
- Effective scheduling.

[What is the enhancement?]
- Configuration file changes. [Proposal-1]
- New interface between BGP DrAgent and DrScheduler will be designed. [Proposal-2]

The feature which this RFE depends on is not yet implemented.
The requested feature can be implemented during the current proposed implementation.
is it really an RFE or a feature-backlog bug?

[Akihiro Motoki (amotoki)]

I marked this as Incomplete temporarily.

[Akihiro Motoki (amotoki)]

On a second thought, it is reasonable and valid as a feature request, so I reset the status to New.
I would like to check how we will deal with this kind of RFEs.

[Armando Migliaccio (armando-migliaccio)]

Thanks for the update. I think it's fair to say that until [1] is feature complete (blueprints implemented - i.e. basic code, tests, docs), bugs [2-7] are blocked. My suggestion would be to go and yell/help the assignee/approver of [1] and make sure that the work can complete successfully asap so that we can start focusing on 2-7 knowing on what grounds we can continue building.

Let's wait for driver's team confirmation..

[Armando Migliaccio (armando-migliaccio)]

Assumed that by the end of Newton (or sooner if possible) the BGP repo is up and running and rock solid based on the efforts put into Mitaka, I see no reason why these requests should not be vetted and addressed by the BGP team directly. So please make a recommendation.
