2. 26th July 201078th IETF @ Maastricht Overview As we have decided in last IETF meeting, we create a separate MIB document for the P2MP PCE. This draft describes managed objects for modeling of Path Computation Element communication Protocol (PCEP) for communications between a Path Computation Client (PCC) and a Path Computation Element (PCE), or between two PCEs in P2MP scenarios. MIB Draft contains –Objects related to P2MP –Objects common for both P2P and P2MP

3. 26th July 201078th IETF @ Maastricht MIB Architecture (P2MP) Two new tables are added, the relationship to the two existing tables in PCE-PCEP-MIB is: – pcePcepSessionTable -------->pcePcepExtSessionTable – pcePcepClientTable ---------->pcePcepExtClientTable An arrow above shows that the MIB table pointed from contains a reference to the MIB table pointed to.

4. 26th July 201078th IETF @ Maastricht New Objects Added 1 New Objects added into pcePcepExtClientTable pcePcepClientPathKeysGenerated; pcePcepClientOverloadStatus; pcePcepClientOverloadDuration;
