The IEEE has ratified IEEE 802.1Qay, the industry\'s first packet-based connection-oriented Ethernet technology for next-generation service provider transport networks.
By adapting Ethernet technology to the role of providing carrier-class packet transport networks, IEEE 802.1Qay helps improve the ability of service providers to deliver cost-effective, high-bandwidth multimedia services to enterprise and residential customers.
IEEE 802.1Qay defines provider backbone bridge traffic engineering (PBB-TE), a technology that helps enable service providers to explicitly set up traffic engineered paths across a carrier Ethernet network.
