High-speed networks are being built using the most up-to-date networking technologies such as optical fibers with Dense Wavelength Multiplexing (DWDM) in order to meet the performance constraints of large scientific problems (grid infrastructures) or new multimedia applications. As technologies are moving forwards, many high-speed network infrastructures have amazing capabilities in the order of several gigabits/s. The authors' focuses on very dynamic high-speed environments where the available best-effort bandwidth for regulated traffics can vary over time. Foreseen problems introduced by such highly dynamic environments are inefficiency due to convergence time and high amount of packet losses due to dramatic reductions of the available bandwidth.
