Proposal of Dynamic Bandwidth Allocation Technique for Low Delay/Low Jitter Realtime Communication and Its Evaluation by Using CBQ

摘要

Recently, traffic of real-time communication such as video or IP telephony is increasing in Internet. Low delay and low jitter communication is required to perform these kinds of services smoothly. CoS (Class of Services) scheme which con- trols traffic by the class unit such as application is currently being paid attention. It is considered to be efficient control mechanism which utilizes characteristics of Internet traffic. One of effective methods for queneing control to realize CoS is CBQ (Class Based Queueing).
