802.1Qay - Provider Backbone Bridge Traffic Engineering

The full title of this PAR is "IEEE Standard for Local and Metropolitan Area Networks---Virtual Bridged Local Area Networks - Amendment: Provider Backbone Bridge Traffic Engineering.".

This amendment will support provisioning systems that explicitly select traffic engineered paths within Provider Backbone Bridge Networks (P802.1ah) by allowing a network operator to disable unknown destination address forwarding and source address learning for administratively selected VLAN Identifiers, while allowing other network control protocols to dynamically determine active topologies for other services. These interoperable capabilities will be supported by SNMP MIB management of individual bridges, by extensions to the other control protocols specified in this standard, by the use of CFM with the addresses and VLAN Identifiers that specify traffic engineered connections, and by 1:1 path protection switching capable of load sharing. This amendment will not take account of multidomain networks.

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.

Provider networks rely on direct control of path routing so that traffic engineering can be used to allocate bandwidth, assure diverse backup path routing, and select path performance as required by service level agreements. Most major carriers, who will be the users of this standard, are currently deploying IEEE 802 based networks and will need traffic engineering capabilities, for load balancing, protection switching, bandwidth management, etc. The existing architecture of bridges and their associated protocols, as specified by 802.1 standards and P802.1ah (Provider Backbone Bridged Networks), allows the further specification of interoperable bridge capabilities that support traffic engineering at the required scale. This project will develop that specification, meeting the (as yet unsatisfied) demand for multi-vendor interoperability and a coherent management framework.
