Dear Dhruv,Stephane,Zhenbin Li,Tarek and WG,
I just submitted a new version of the draft-peng-pce-entropy-label-position-05.
This draft has been presented in IETF 106 and 107. Many thanks for your
comments and discussions.
First, I think we have the consensus that in case of inter-domain scenario, PCE
would be useful for computing both SR path and the placement of entropy labels.
We should propose a set of extensions for PCEP.
Second, I fully agree with that the ingress MUST support the capability of
inserting multiple ELI/ELs and it needs to advertise the capability to PCE. So
I think we should add the capability in OPEN message from PCC to PCE. In the
current version, we define the E bit for a PCC to indicate that it supports
the capability of inserting multiple ELI/EL pairs and and supports the results
of SR path with ELP from PCE. What is your suggestion? If the E bit is enough?
Or should we define the BGP/IGP extension?
Finally, thanks to Zhenbin, I need to clarify that the ELI/EL pairs are
calculated for a specific traffic flow but the placement of the ELI/EL pairs
are calculated for a SR-path. In our draft, we propose the PCEs perform
computation of SR-path with the the placement of the ELI/EL pairs and the value
of ELI/EL pairs are calculated at the ingress.
I look forward and appreciate any comment and suggestion from you.
Thanks,
Quan
