Public bug reported:
[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]
