Class-Based Rate Control Using a Multi-Threshold Leaky Bucket

摘要

The controller has a leaky bucket with an initial maximum number of tokens that decreases as packets are received in an associated output buffer. Multiple token availability threshold level registers (206) specify multiple token amounts defining token availability regions. A packet transmission suppression controller selectively suppresses the transmission of a packet based on a current token availability level. Independent claims are also included for the following: (A) an communication network node (B) an ingress rate controller monitoring content traffic received at an edge network node of a packet-switched communications network node (C) a method of effecting egress rate control.
