Ethernet has been the dominant technology for local area networks (LANs) for many years. With the introduction of circuit concept over Ethernet by the IEEE and MEF specifications, Ethernet is becoming a key technology for Metropolitan Area Networks (MANs) and Wide Area Networks (WANs). This book makes an attempt to describe various aspects of data networks and services based on carrier Ethernet, pseudowires (PWs), transport multi- protocol label switching (T-MPLS), multiprotocol label switching transport pro- file (MPLS-TP), and virtual private local area network service (VPLS). Chapter 2 describes the basics of Ethernet, such as protocol stack, bridges, switches, and hubs. Chapters 3, 4, and 5 cover the key techniques that are being used in building carrier class Ethernet networks and services, namely, synchronization, PWs, and protection, respectively. Chapter 6 begins describing Carrier Ethernet network architecture and ser- vices that are currently deployed in the industry and evolving. It is followed by Chapters 7 and 8, describing traffic management and Ethernet Operations, Admin- istrations, and Maintenance (OAM) capabilities of Carrier Ethernet1, respectively. Chapter 9 is devoted to circuit emulation services (CES) because of its complexity. For the same reason, Chapter 10 is devoted to Ethernet local management interface (ELMI). Addressing scalability of Carrier Ethernet is being questioned, despite of the availability of S-Tag and C-Tag combination. Provider Backbone Bridges (PBBs) and Provider Backbone Transport (PBT) resolve this scalability issue. Chapter 11 describes these technologies in detail. Three technologies, namely, T-MPLS, MPLS-TP, and VPLS can compete or work with Carrier Ethernet in forming data networks. Chapters 12, 13, and 14 describe them in detail.
