public class PCEPMonReq
extends PCEPMessage

Path Computation Monitoring Request (PCMonReq) Message (RFC 5886).

The Message-Type field of the PCEP common header for the PCMonReq message is set to 8.

There is one mandatory object that MUST be included within a PCMonReq message: the MONITORING object. If the MONITORING object is missing, the receiving PCE MUST send a PCErr message with Error-type=6 (Mandatory Object missing) and Error-value=4 (MONITORING object missing). Other objects are optional.

Format of a PCMonReq message (out-of-band request):

::= [] [] [] where: ::=[] ::= [] [] ::=[] ::= [] [] [] [] [] [] [] ::=[]

The SVEC, RP, END-POINTS, LSPA, BANDWIDTH, METRIC, RRO, IRO, and LOAD-BALANCING objects are defined in [RFC5440]. The XRO object is defined in [RFC5521] and the OF object is defined in [RFC5541]. The PCC-ID-REQ object is defined in Section 4.2.

The PCMonReq message is used to gather various PCE state metrics along a path computation chain. The path computation chain may be determined by the PCC (in the form of a series of a series of PCE-ID objects defined in Section 4.3) according to policy specified on the PCC or alternatively may be determined by the path computation procedure. For example, if the BRPC procedure ([RFC5441]) is used to compute an inter-domain TE LSP, the path computation chain may be determined dynamically. In that case, the PCC sends a PCMonReq message that contains the PCEP objects that characterize the TE LSP attributes along with the MONITORING object that lists the set of metrics of interest. If a list of PCEs is present in the monitoring request, it takes precedence over mechanisms used to dynamically determine the path computation chain. If a PCE receives a monitoring request that specifies a next-hop PCE in the PCE list that is unreachable, the request MUST be silently discarded.
