Investigation on TCP/IP Congestion Control in Optical Burst Switched (OBS) Network

摘要

Transp ort Cont rol Proto col (TCP) is the dominant protocol in mo dern co mmunica tion net work s, in which the i ssues of relia bility, flo w, a nd congestion co ntro l must b e ha ndled efficiently. In t his review pa per an a nalytical swit ching is used to explo it the huge b and widt h of opti cal fibers fo r fut ure high sp eed internet backbone. It carries multipl e pa ckets, in their turn. Different agg rega tion schemes have been considered and evalua ted.TCP performance greatly dep end s on the TCP co ngestion window behavi or that i s rel ated to lo ss event s occurri ng in the op tical burst swi tched network, there is a sp ecia l term called traffic shapi ng b y which we co ntro l over the network accord ing to t he netwo rk l oad .that means we increase o r decrea se t he send rat e accord ing t o the net work demand .
