Introduction:This paper presents a minimum delay congestion control in differentiated Service communication networks. The premium and ordinary passage services based fluid flow theory is used to build the suggested structure in high efficient manage. The established system is capable to adeptly manage both the physical network resource limitations and indefinite time delay related to networking system structure.Methods:The effectiveness of the suggested congestion controller system is demonstrated with mathematical consequences in formal framework by using modified sliding controller (MSMC) techniques. This technique provides high utilization and less delay after adapting the state feedbacks controllers with sliding mode controller. The Quality of Service (QoS) requirements in term of effective and dynamic regulation of network resources have been achieved in the existing design.Results:The capacity and bandwidth limitations are considered as a restriction on the input of network. The results of this approach are developed and compared with a conventional design.
