| Abstract: | This paper analyzed the effect of deflection routing on network performance and the sending end controlled deflection routing technology, propesed an improved scheme based on threshold checking and data updating. In this scheme, the edge nodes can quickly update the status informations of network, and transfer the informations such as the link blocking distribution through special control packets. The switching nodes can perform threshold checking, determine the burst transmission mode in the case of competition, so as to reduce the influence of deflection routing on network load, decrease the network blocking probability, and improve the network performance. |

| Keywords: | optical burst switching deflection routing blocking probability performance |
