![]() ![]() The below API are implemented for tunnel provider in PCEP SBI SetupTunnel APIĭetails: This API is responsible for setting up a tunnel on the device. All communication between PCEP provider and ONOS Core uses Provider Service interface. In this case PCEP Tunnel Provider will invoke the respective API to notify ONOS Core about the result of create or update or release tunnels. The Report message can also be the result of PCE initiated messages for creating, updating or releasing tunnels. These report messages are notified to PCEP Tunnel Provider via message listener which in turn will inform the ONOS Core about the existing tunnels in the network. ![]() Implementation supports state synchronization with PCC reporting reporting LSPs’ state to PCEP protocol handler running on ONOS immediately after session established. Currently the messages supported are Open, KeepAlive, PCInitiate, PCUpd, PCRpt, PCLabelUpd, LSRpt, PCLRResv, PCErr and Close. ![]() Implement PCEP message handler, which will encode and decode PCEP messages between ONOS PCEP SBI and PCC. A channel handler will be created for each PCEP session to maintain the state machine and state of each PCC. Implement PCEP protocol handler, which acts as a server to listen on PCEP port 4189 to establish and manage session with PCCs. The implementation will also support learning of existing active tunnels which are on the network. Proposed workĪdd PCEP South Bound Interface (SBI) for MPLS TE tunnel management which will implement TunnelProvider API to support initiating, updating and releasing of PCE initiated tunnels using PCE communication protocol. Huawei project adds Path Computation Element Protocol (PCEP) as a southbound plugin in ONOS. ![]()
