A channel handler will be created for each BGP session to maintain the state machine and state of each Peer.
...
- Implement BGP message handler, which will encode and decode BGP messages between ONOS BGP SBI and BGP peer on network. Currently the messages supported are open, KeepAlive, update, Notification and BGP Multiprotocol message with Link state descriptions and its attributes.
...
- Implement BGP LS topology provider to update Node and Link subsystem of ONOS core when any node or link gets added/deleted or modified. All communication between BGP Linkstate provider and ONOS Core uses Provider Service interface.
