This is not only a technology shift, but also a shift in theoperational and business model that will allow the incumbent carriers to transform the metro tooffer enhanced data services.Metro Ethernet from Cisco Press looks at the deployment of metro data services from a holisticview. It describes the current metro, which is based on TDM technology, and discusses thedrivers and challenges carriers will face in transforming the metro to address data services.Metro Ethernet discusses the adoption of metro Ethernet services and how that has led carriersto the delivery of metro data services. With a changing mix of transport technologies, the bookthen examines current and emerging trends, and delves into the role of virtual private networks(VPN), virtual private local area networks (VLAN), virtual private LAN services (VPLS), trafficengineering, and MPLS and Generalized MPLS (GMPLS).
