Hi Gyan,

We have implemented PCEP in the past.&nbsp;
This experimental upgrade of PCEP to enable direct TE updates to PCE is worth to try and we'd be interested in the implementation of this work.

Regards,
Bin

Dear PCE WG,

We presented the PCEP-LS [1] I-D [2] in the IETF 110 with a quick recap and a summary of past discussions. Some new scenarios such as PCECC, H-PCE were highlighted where the PCEP session could be reused.&nbsp;

This is an experimental I-D with the aim to progress research and development efforts. This work is not a replacement for any of the existing mechanisms. There are specific scenarios highlighted where the reuse of PCEP sessions for this information is deemed useful. To make progress, it may not be useful to rehash the beauty context between everyone's favorite protocol :). What would be useful would be - finding out if there is still interest in this experimental work by some in the WG; are there strong technical objections for the experiment in its limited scope etc...&nbsp;

As a next step, it would be good to define the scope of the experiments and expected output especially targeting the scalability concerns as well as impact in other protocols and the network, etc. &nbsp;&nbsp;

Thanks!&nbsp;
