public class SRP
extends PCEPObject

SRP Object. The SRP (Stateful PCE Request Parameters) object MUST be carried within each PCUpd and PCRpt message and MAY be carried within PCNtf and PCEerr messages. The SRP object is used to correlate between update requests sent by the PCE and the error reports and state reports sent by the PCC. The P flag in the common object header of the SRP object MUST be set to 0. SRP Object-Class is [TBD]. SRP Object-Type is 1. The format of the SRP object body is shown in Figure 17: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Flags |R| +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | SRP-ID-number | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | // Optional TLVs // | | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Figure 17: The SRP Object format The SRP object body has a variable length and may contain additional TLVs. The SYMBOLIC-PATH-NAME TLV MAY be included as one of the optional TLVs. Flags (32 bits): None defined yet. SRP-ID-number (32 bits): The SRP-ID-number value combined with the source IP address of the PCC and the PCE uniquely identify the operation that the PCE has requested the PCC to perform on a given LSP. The SRP-ID-number is incremented each time a new request is sent to the PCC, and may wrap around. The values 0x00000000 and 0xFFFFFFFF are reserved. Every request to update an LSP receives a new SRP-ID-number. This number is unique per PCEP session and is incremented each time an operation is requested from the PCE. Thus, for a given LSP there may be more than one SRP-id-number unacknowledged at a given time. The value of the SRP-ID-number is echoed back by the PCC in PCErr and PCRpt messages to allow for correlation between requests made by the PCE and errors or state reports generated by the PCC. If the error or report were not as a result of a PCE operation (for example in the case of a link down event), then the reserved value of 0x00000000 is used instead. An SRP-ID-number is considered unacknowledged and cannot be reused until a PCErr or PCRpt arrives with an SRP-ID-number equal or higher for the same LSP. A PCRpt with state "Pending" is not considered as an acknowledgement.
