Hello Anna, I agree with Ruediger. I think PCN WG should tackle IP/MPLS together because more and more high available applications use MPLS transport mechanism. IP based marking may not effectively improve the application QoS. It would be better to study both together.

At the same time, drafts relevant for PCN need to be discussed and announced to the PCN BOF/WG. And mpls-ecn certainly is one of them. So my position is discussion in both WGs. If it was of help in transforming the pcn bof to the pcn WG, then I'd favour the PCN bof as the home of draft-davie-ecn-mpls.

This is a very important function |for QoS. The draft charter covers many features from IP perspectives (I |think). Should we also cover features from MPLS perspective? Something |like PCN per LSP. How could PCN contain the sufficient informaton for |edge router or CL to take an action on it? For multiple |segements having congestion potential, could a consolidated PCN be |propagated to the ingress or egress edge router? |Should RSVP be used in PCN for a LSP or a bit is inserted in packets? | |Anyway this is a good starting point. | |Best Regards, |Lucy Yong | | |*************************************************************** |********* |******************* | This email and its attachments contain confidential information from |HUAWEI, which is intended only for the person or entity whose |address is |listed above.
