... ..........................................................VLAN Tagging per IEEE 802.1q, Q-in-Q Mapping per 802.1ad, Provider Backbone Transport (PBT) per 802.1ah; Carrier Ethernet Services Attributes per Metro Ethernet Forum (MEF) 9 and MEF 14 VLAN Support .......................................... ...

... . But Ethernet needs circuit-like capabilities to displace and replace SONET/SDH--this is the purpose of new Ethernet tunneling protocols, including PBT (provider backbone transport), PBB-TE (provider backbone bridging-traffic engineering), MPLS-TP, and others. The Ethernet tunnels will eventually allow ...

... . Using PBB-TE in 4G Wireless Backhaul Networks In early 2007, IEEE 802.1 commissioned a project to standardize Provider Backbone Transport (PBT) as PBB-TE. Known as IEEE 802.1Qay, the effort will produce a standard that defines enhanced Ethernet-based techniques for transporting services across diverse ...

White Paper Beyond Carrier Ethernet: Making Ethernet Performance-Grade Introduction TODAY, VIRTUALLY ALL NEW END-USER and most new machine-tomachine applications are designed around the Internet Protocol (IP). Within 99 percent of Local Area Networks (LANs), Ethernet is used to carry those IP packets ...

Introduction: The Importance of Optical Transport Network (OTN) Cable operators' Hybrid Fiber-Coax (HFC) plants pass within half a mile of some 80 percent of business locations. Therefore, extending the fiber plant to reach mid-sized to large businesses has never been easier or more rewarding. These ...
