Need of more bandwidth is increasing day by day. To fulfill this demand high speed fiber optical communication can be used. In fiber optic networks buffering is a phenomenon, by which except one other contending packets are stored in fiber delay lines. In network due to random connections among the nodes, path traverses from a source node to destination node varies, thus cost also varies. More over intermediate nodes also affect the performance of the networks. Therefore in past study both buffering and deflection routing for load balancing was suggested to tackle contention problem. In this work it is shown that in network deflection will increase un-necessary traffic in the networks and contention problem become more severe. Therefore, it is concluded that buffering of contending packets in better choice.
