Peering Carrier Ethernet Networks addresses interoperability of Carrier Ethernet networks—key to leveraging time-sensitive applications over the Internet—describing the context and problem while providing solutions and related industry standards. The book starts with a brief history of communication and data networks to show how a proliferation of different communication technologies led to the convergence around Ethernet as a unifying protocol. Convergence alone has not solved the interoperability therefore the need for peering these networks, a model that allows communications providers to offer their clients services through other providers. Peering Carrier Ethernet Networks provides an overview of circuit switching, multiplexing, and voice digitization that lead to the development of T1 and T3 for trunks. It interleaves these developments with describing the emergence of data networks and the associated OSI 7 layer model, packet switching, TCP for Layer 4, IP for Layer 3, and Ethernet for Layer 2 in LAN. It covers the evolution of wireless networks, exploring the emergence of multiple choices in Access networks and convergence in the back haul. It explores the multifarious access modes to meet the increased demand for bandwidth and to reduce latency and jitter, describing the limitations of supporting multiple protocols. Further, the book covers the emergence of Ethernet as the protocol leading to the Carrier Ethernet networks. It explores Carrier Ethernet networks technical standards, describing how service providers can offer services to "off-net" customers using peered Carrier Ethernet networks. It describes the Layer 2 and Layer 3 services on peered Carrier Ethernet networks, demonstrating the necessity of a robust OSS/BSS system and an industry standard for exchanging orders between operators. The book concludes by describing the evolution of OSS/BSS systems architecture to eTOM and NGOSS model for co-ordinating Marketing, Infrastructure, Physical and Virtual Inventory, Customer, Product, Resource, and Service, and Operations Management. Detailed coverage of end-to-end services across wide area data networks. Consolidates in one ready reference the latest applied research in this rapidly evolving field. Provides the context, advantages, and industry standards for peering Carrier Ethernet networks.
