Optical burst switching (OBS) network is viewed as two parallel networks, namely a data and a control network (plane). In this paper, the main focus has been given only on the impact of control-plane on performance of OBS. In high speed networks, several factors such as contention, insufficient offset-time, average burst length and scheduling operations may cause excessive delay in processing of control packets in an electronic core-node controller, thus as a result incur higher blocking probability, inefficient bandwidth utilization etc. In this paper, to address this, an analytical modeling, detailed analysis of control plane and its impact on OBS performance has been provided. Based on above, optimal performance oriented parameters can be selected such as average burst length, sufficient offset-time duration and scheduling and reservation operations in order to show the impact of control-plane negligible (as compared to data-plane) on OBS based system performance.
