To reduce the burst blocking probability and protect the quality of service(QoS) in optical brust switching(OBS) networks,a resource reservation mechanism based on window with continuous-time variable offsets in emulated-OBS(E-OBS) networks is proposed.The mechanism sets a resource reservation window in the control channel of the E-OBS core routers,and it will determine whether control bursts are allowed to reserve the link resource for data bursts.A fixed-point approximation equation based on t...
