Abstract
Providing different levels of quality of service for different data flows being transported over a data link requires a very fast way to schedule individual packets for forwarding on the data link. The invention provides scheduling methods which give preference to higher priority packets while treating lower priority packets fairly. The methods can provide shorter latencies for higher priority packets than can many prior scheduling methods. The methods and apparatus of the invention are readily adaptable for use with scheduling rules provided in the form of hierarchical policy trees.
