Bandwidth Management with Congestion Control Approach and Fuzzy Logic

One of the problems with today's TCP/IP networks is their transmission system. If bandwidth a network full, human and physical factors must be used for new system higher capacity to provide its bandwidth, which very time consuming costly. In this article, we proposed method that in addition optimal use available if it will automatically transferred network. For purpose first, by designing fuzzy PID controller existing network, tried congestion control them make it. It can seen performs much better terms an output response, following queue length, stability uncertainly, compared classical controller. input data increased, more packets are lost reduces quality To solve problem using management, considering threshold loss each exceeding limit, switched solved causes subscriber satisfaction.
