Abstract

See full text

A system and method for reducing network node congestion by filtering out comparatively low priority packets prior to execution of other node functions, such as routing and switching, in packet-based network transmissions. The volume of packets is reduced by intercepting the information packets prior to their input to the network node. A portion of the intercepted packets are filtered out based on parameters corresponding to a probable packet acceptability at the network node. The remaining portion of the intercepted packets are forwarded to the network node for processing by the network packet functions.
