Abstract
Conventional packet network nodes react to congestion in the packet network by dropping packets in a manner which is perceived by users to be indiscriminate. In embodiments of the present invention, indiscriminate packet discards are prevented by causing packets to be discarded according to bandwidth allocations that intelligently track flow sending rates. Flows are allocated bandwidth based on policy information. Where such policy information indicates that the flow should be treated as delay-sensitive, the present invention includes means to allocate an initial minimum rate that will be guaranteed and such flows will also have the use of an additional capacity that varies depending on the number of such flows that currently share an available pool of capacity. This provides a congestion alleviation method which is less annoying to users since communications that have been in existence for longer are less susceptible to component packets being deleted.
