Multipath Routing Mechanisms for Traffic Engineering and Quality of Service in the Internet

The success of the IP architecture is largely due to the simplicity, robustness and scalability that resulted from its the connectionless design methodology. As the Internet evolves it must support new services such as QoS and when extensions are made to the IP architecture to support such services, its basic connectionless model must be preserved to retain the scalability and robustness that made it so successful. In the past few years, with the Internet becoming the main communication infrastructure IP networks are faced with two challenging problems that require immediate attention traffic, engineering and supporting guaranteed services providing efficient, robust and scalable solutions to these problems within the framework of the connectionless IP has become extremely important and urgent.
