System and method for controlling packet transmission in a communication network

摘要

A system for controlling packet transmission in a communication network includes: a classifier for classifying a plurality of packets into different types and for transmitting the classified packets based on a service level agreement (SLA); a meter for determining whether data arrival rate of packets received from the classifier is more than a token rate, and if so, considering the packets as in-profile packets, or otherwise, considering the packets as out-profile packets; a marker for re-marking packets received from the classifier and out-profile packets that need to be transmitted first based on the SLA; a traffic adjuster for discarding out-profile packets that do not need to be transmitted first based on the SLA; and a classifying server for providing differentiated bandwidths for packets received from the classifier and the traffic adjuster. A related method for controlling packet transmission in a communication network is also provided.
