Dear All
I like to understand more about LSPA Object defined in PCEP.
1. What will be content of the following fields?
* Exclude-any
* Include-any
* Include-all
2. More information can be added into PCEP RFC
3. What is the use-case of this object
4. If more than one request is present in a single PCReq message, How LSPA
object is associated with a single request present in the message?
General comment: PCEP RFC has lot of Typo errors and the same can be
rectified. I will also review and provide my comments in the mean time.
Thanking you,
Best regards,
S.SenthilKumar
7.11. LSPA Object
The LSPA object is optional and specifies various TE LSP attributes
to be taken into account by the PCE during path computation. The
LSPA (LSP Attributes) object can be carried within a PCReq message,
or a PCRep message in case of unsuccessful path computation (in this
case, the PCRep message also contains a NO-PATH object and the LSPA
object is used to indicate the set of constraints that could not be
satisfied). Most of the fields of the LSPA object are identical to
the fields of the SESSION-ATTRIBUTE (C-Type = 7) object defined in
[RFC3209] and [RFC4090]. When absent from the PCReq message, this
means that the Setup and Holding priorities are equal to 0, and there
are no affinity constraints.
LSPA Object-Class is to be assigned by IANA (recommended value=9)
LSPA Object-Types is to be assigned by IANA (recommended value=1)
The format of the LSPA object body is:
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
