Cisco ConfidentialPresentation_IDNew Kids on the BlockEmerging and Revisited Ideas1. 802.1ay Provider Backbone Bridging Traffic Engineering (PBB-TE) / PBT2. Transport MPLS (T-MPLS) ITU G.81103. These are initiatives by traditional telecom vendors4. Common characteristics are:their goal is leveraging the installed base of SDH / L2 gearforce customers towards proprietary solutionsthe rely on NMS / OSS systems ( no dynamic control plane in the network )No multi service capabilities16 2008 Cisco Systems, Inc.

In a sentence:Basically using 802.1ah data-plane functionality with OSS/NMS provisioning in lieu of IEEE control protocols (MSTP, GVRP, etc.) to setup P2P VCs.2. It Consists of the following three components:Data-plane based on 802.1ah OAM based on 802.1agA protection switching mechanism similar to MPLS TE Path Protection (protection path switching between two edge switches)17 2008 Cisco Systems, Inc.
