Method for packet network traffic regulation

摘要

A method of traffic regulation in a packet communication network involves a token bucket associated with a subscriber. Packets arriving at the regulator are handled in accordance with the token bucket configuration. The method involves measuring a demand placed on the network by the subscriber. The token bucket configuration is dynamically adjusted based on the demand. Another method of traffic regulation handles packets arriving at the regulator in accordance with first and second token bucket configurations. The first token bucket regulates packet rate while the second token bucket regulates data rate. Another method of traffic regulation involves handling packets in accordance with a token bucket configuration, where the amount of tokens to be removed is based on the amount of the flow and is further based on a classification of the flow. Packet-level devices for traffic regulation are also contemplated.

主权项

1. A method comprising:
receiving, by a device in a network, one or more packets corresponding to a packet flow associated with a user; removing, by the device, an amount of tokens from a token bucket, the token bucket having a token bucket depth and a sustain rate, wherein the amount of tokens is determined based on a flow amount associated with the one or more packets and a token multiplier associated with a classification of the one or more packets; determining, by the device and based on a remaining number of tokens in the token bucket, that a burst demand placed on the network by the user over a first period of time has met or exceeded the sustain rate and, in response to determining that the burst demand has met or exceeded the sustain rate, temporarily reducing the token bucket depth; and determining, by the device and subsequent to determining that the burst demand has met or exceeded the sustain rate, that a data traffic pattern associated with the user has remained under the sustain rate for a minimum period of time and, in response to determining that the data traffic pattern has remained under the sustain rate for the minimum period of time, restoring the token bucket depth.
