TABLE OF CONTENTS This section discusses the different ways that metro Ethernet can be used for simple, effective applications. These applications include e-commerce ( electronic data interchange [EDI]), streaming video, streaming audio, connectivity to ASPs, distance learning, video conferencing, content distribution, business continuity, LAN extension (TLAN), SANs, virtual Ethernet, and e-mail transmissions.

The common threads among the applications for GigE and 10 GigE transport are
A demand for higher bandwidth Metro area bandwidth requirements have expanded rapidly as a result of application outsourcing, campus/building connections, and the general growth in Internet traffic. New collocation services (such as carrier hotels) require high-speed communication for data centers, application hosting, and so on. The new last-mile solutions (such as xDSL, wireless broadband, and cable modems) are also forcing metro network providers to upgrade core network capacity to keep up with their customer s use of high-bandwidth services.
Provisioning of feature-rich services Although having larger pipes is fundamental, the real key to competitive success is to create value-added services. Rapid service provisioning, priority services, and integrated management are examples of features that need to be built into an intelligent network. Service features should also be transparent and consistent across the LAN, MAN, and WAN environments.
Integration and convergence The mix and nature of traffic on the network will change...
