What are the problems with traffic engineering a IP backbone?
Provider Backbone Bridge Traffic Engineering (PBB-TE) is a computer networking technology specified in IEEE 802.1Qay, an amendment to the IEEE 802.1Q standard. PBB-TE adapts Ethernet to carrier class transport networks.
May 22, 2007 · An essential requirement of many provider networks is supporting traffic engineered paths. Complete route selection freedom must be allowed for a large number of connections. This amendment enables a Service Provider to traffic engineer provisioned connections in a Provider Backbone Bridged network using familiar 802.1 bridging technology.
IEEE 802.1ah Provider Backbone Bridging Overview. The Institute of Electrical and Electronics Engineers (IEEE) 802.1ah PBB feature encapsulates or decapsulates end-user traffic on a Backbone Edge Bridge (BEB) at the edge of the Provider Backbone Bridged Network (PBBN).
In a standard Provider Backbone Bridged Network (802.1ah PBBN) traffic engineering is limited as a consequence of the use of IEEE 802.1Q MSTP control plane protocols which control the population of the bridge filtering tables.
What is PBB-TE? Provider Backbone Bridge Traffic Engineering (PBB-TE) is a computer networking technology specified in the IEEE 802.1Qay standard. It builds upon the foundation of Provider Backbone Bridging (PBB), another Ethernet-based technology designed for carrier-grade networks.
Jan 1, 2010 · This chapter is a hands-on description of the practical structure and implementation of IP backbone networks and is principally motivated by the observation that in large carrier networks, the IP backbone is not a self-contained entity; it co-exists with numerous access and transport networks operated by the same or other service providers.
Nov 5, 2009 · Localize changes in traffic distribution due to failure or maintenance actions. It is anticipated that Traffic Engineered bridged networks will be widely deployed when the PBB-TE (IEEE Std. 802.1Qay) standard becomes available. Currently, only a hierarchy of end-to-end 1:1 TESI protection is specified.
