Definitive guide to enterprise applications and carrier metro Ethernet Easy to read and understand, following the style of the best selling Internet service Metro Ethernet Routing ArchitecturesUnderstand appear as point-to-point packet-leased line services and multipoint-to-multipoint VPLSLearn to scale your Ethernet LAN beyond the enterprise wall and across geographic virtual private campusUnderstand drivers and challenges faced by the operator to change the metro to address data servicesUnderstand different metro deployment models using SONET / SDH, next generation SONET / SDH, Ethernet over SONET / SDH (EOS), virtual circuit, Generic Framing Protocol (GFP), and Resilient Packet Ring (RPR). Check the VPLS model and how MPLS can extend services in the MAN and WANLearn L2 on the characteristics of GMPLS architecture Metro networks have emerged as an area of growth for the networking industry and represent a major change in how the data services offered to business and residential customers. This is not only a shift in technology but also a shift in operational and business models that will allow incumbent operators to change the metro to offer enhanced data services. Ethernet has become the technology of choice for companies and now emerged as a preferred access interface to provide data services in the metro. It gives an overview of the current metro, which is based on TDM technology, and discuss the drivers and challenges to be faced in transforming the metro to address data services. Metro Ethernet discuss the mix of transport technologies deployed in metro and migration strategies that metro operators will adopt in moving away from SONET / SDH day to all Ethernet networks. GMPLS presents a major change in the operation and configuration of transport networks and will greatly influence the spread of future metro and WAN networks. This book is part of the Networking Technology Series from Cisco Press (r), which offers networking professionals valuable information to build efficient networks, understanding new technologies, and build a successful career.
