Multi-service Token Bucket Algorithm of MAC QoS System in Access Network
DU Li-guo · 2009
To adjust the traffic burst rate and support dynamic service flows,a multi-service Token Bucket Algorithm was proposed to Quality of Service architecture in Cable Modem of HFC access network,based on a token assignment module between token generator and bucket,and polling policy. The Acceptance Test Plan,defined by Cable Television Laboratories,was used to analyse the impact of queue depth on the delay and jitter and comparison output rate with input rate,the result shows that this algorithm meets the application requirements and controls the rate shaping effectively.
