Abstract: Differentiated service network is used to provide QoS (Quality of service) in an IP network with the help of Dynamic admission control algorithm. Bandwidth broker, an important part of Diff-serv network, performing all the controlling function of Diff-serv network. Admission control module is an integral part of bandwidth broker. The aim of admission control algorithm is to achieve good quality of service by increasing network bandwidth utilization and efficient resources allocation. NS2 simulator is being used to perform the task of achieving QoS in Differentiated service network with Dynamic admission control algorithm.
Keywords: Differentiated service network, Bandwidth broker, Dynamic admission control algorithm
