Generic Tunnel Subsystem (ONOS-1276) and L1/L0 (OTN/ROADM)extensions (ONOS-676):
1)Initial Work for ONOS-676: OTN/ROADM (L1/L0 NE) support in ONOS by extending the device/port modeling;
- extending device type to include L1 OTN NEs;
- extending port type to include ODUCLT port(T-port), OCH-port(L-port), OMS-port (WDM-port);
- more standard annotations related to OTN/ROADMs support will come from PCEP provider as well as TL1 providers;
2)Intial Work for ONOS-1276: generic Tunnel subsystem in ONOS for both packet (L3/L2) networks and optical (L1/L0) networks
- supporting PCEP framework, which is capable of interacting with the PCEP provider;
- supporting any other kind of tunnel provider;
- each Tunnel is associated with at least two Labels (abstracted logical entity/Id for virtualization of physical port);
- same type of Tunnels can be formed as a reachablity graph for other services and NB applications use;
