To CCAMP WG co-chairs and IEEE-IETF liaisons: From: IEEE 802.1 Working Group Thank you for your query of June 4, 2007, reproduced below so that it is clear what question is being answered: "Body: The CCAMP Working Group of the IETF notes the recent approval of a PAR for the 802.1Qay project, and we understand that part of the intent of this project is to support provisioning systems that explicitly select traffic engineered paths within Provider Backbone Bridge (802.1ah) Networks." This is correct. The first meeting of P802.1Qay (PBB-TE) was in May 2007. For your information, the official home page of the project can be accessed at "It has been suggested that GMPLS protocols developed within the IETF under the care of the CCAMP Working Group are suitable aids to such provisioning systems. We propose to investigate the applicability of GMPLS protocols to the control of 802.1Qay networks, and we would like to work with the IEEE by proposing suitable GMPLS protocol extensions for use in single and multi-domain networks subject to 802.1 reaching consensus on the definition of the data plane." IEEE 802.1 currently has no GMPLS related protocol work under development and therefore has no opinion on whether GMPLS is suitable to control 802.1Qay networks. Note that the scope of P802.1Qay is single domain networks. "Please confirm that in your opinion the use of GMPLS control plane protocols in this way is appropriate, and that IEEE 802.1 has no objection to the IETF CCAMP Working Group starting work in this area." Although IEEE 802.1 holds no opinion on GMPLS control plane work, the IEEE 802.1 working group does not object to work that is compatible with IEEE 802.1 data planes. Note that IEEE 802.1 reserves the right to develop its own control planes for PBB-TE. For your information, the only projects currently underway that are related to control planes is P802.1aq for Shortest Path Bridging and P802.1Qat for bandwidth reservation. Regards, Tony Jeffree Chair, IEEE 802.1 Working Group
