Today’s Internet is increasingly strained to meet the demands and requirements of these Internet services and their users, such as scalability to accommodate the increasing number of network components and host devices, high availability (i.e., “always-on” services), robustness, mobility and security. As the universal “glue” that pieces together various heterogeneous physical networks, the Internet Protocol (IP) suffers certain well-known shortcomings, e.g., it requires careful and extensive network configurations – in particular, the need for address management and configuration, inherently reactive approaches for handling network failures, relatively poor support for mobility, and so forth. In addition, despite the potential benefits offered by a larger address space, transition from IPv4 to IPv6 has been difficult and slow; among a variety of other factors, the tight coupling of addressing, routing and other network layer functions clearly make such transition not an easy task. While Ethernet is largely plug-&-play, as it was originally developed for small, local area networks, this traditional layer-2 technology can hardly meet the scale as well as the demanding efficiency and robustness requirements imposed on today’s large, dynamic networks.
