A scheduler and method for use in packet communication systems apply a generalized discrete-rate scheduling technique which removes the limitation of the linear increase in sorting complexity with the number of supported service rates. The set of supported service rates may be increased without increasing...http://www.google.se/patents/US7031255?utm_source=gb-gplus-sharePatent US7031255 - Method and apparatus for guaranteeing data transfer rates and delays in data packet networks using generalized discrete data transfer rate approach
