Re: [Teas] Initial version for liaison text //答复: CALL FOR VOLUNTEER - New Liaison Statement, "Achieving Packet Network Optimization using DWDM Interfaces"

[Daniele Ceccarelli <[e-mail]>]

Hi Haomian, all,



Thanks for starting putting together the reply. Please find some updated proposals from my side.



===========================

The working groups in IETF routing area would like to thank you for sending this liaison. We much appreciate BBF on the effort of packet over optical, and sending the document to IETF CCAMP, TEAS and PCE WGs for review. This project defines a set of control plane requirements that the Physically Separated Model should be satisfied. We have some questions and comments:



Questions:

·         It is not clear to us how the communication between the packet layer and the optical layer occurs. E.g. control channels, signaling and so on.

·         We would like to see some more details on the management aspects between the packet domain and the optical domain.

Comments:

·         When referring to PCE and related issues, e.g., in [R-26] and [R-27], it seems only stateless PCE (RFC4655) and corresponding PCEP (RFC5520) are included in the current version. As IETF PCE working group is investigating on stateful PCE, PCE Initiation and PCE as a Central Controller, which are planned to be published in the future, it is better to specify which kind of PCE is now referred by this documents. Moreover, RFC 5623, PCE-based inter-layer MPLS and GMPLS Traffic Engineering, may be a good reference for this document.

·         In section 4.4 when talking about SDN, Openflow is mentioned as a standard protocol to interact between packet nodes and DWDM nodes. We would like to suggest add PCE Protocol (PCEP) as another example, as it is currently used in IETF. Besides, it is suggest to reference to RFC 3413 about SNMP, and RFC 4208 about GMPLS UNI.

·         In section 4.5, [R-36] is not clear whether to be applied to the north-bound of SDN controller, or between the packet NE and SDN controller. We prefer the latter one.



It seems to us the requirements proposed in the current document could be addressed by the referenced RFCs defined for GMPLS, so we would like to make sure if you have identified any gaps, which need an update on GMPLS/PCEP to satisfy these requirements. IETF CCAMP is discussing to define a framework for Management and Control of DWDM optical interface parameters and GMPLS protocols that need to be updated, which might be relevant to your project, but this work in CCAMP is still in individual drafts stage. We would like to receive your input.

============================



Thanks

Daniele
