Strong AT&T Involvement in IETF GMPLS and ITU/OIF UNI/E-NNI protocols

AT&T an initiator of many basic GMPLS concepts – IP control of optics, shared mesh restoration, SRLGs, managing all-optical impairmentsAT&T strong contributor from very beginning at IETF, OIF, ITU

Editor of OIF�s Carrier Requirements document in the OIF Carrier WG � only industry group exclusively focused on carrier requirementsLead of IETF�s Design Team on GMPLS support of ITU ASON requirementsActive in work across all critical standards / interop forums on signaling, routing and restoration documents

AT&T Research - Leading-edge, early prototype demonstrations of feasibility (2000-2002)Participant in OIF interop-demos (inter-working across carrier labs across the world)
