- Optical Burst Switching (OBS) is one of the most important switching technologies for future IP over wavelength division multiplexing (WDM) networks. In OBS Network, the burst assembly technique is one of the challenging issues in the implementation of the system. It has the influence on the burst characteristic, which gives an impact on the network performance. In this paper, an efficient hybrid burst assembly approach based on approximate queueing network model has been proposed. An approximate queueing network model has been used to reduce the time complexity in comparison to exact model. Throughput performance is investigated taking into account both burst loss probability and the time complexity of the proposed approach. Simulation results indicate that the hybrid approach based on variable burst length threshold and fixed maximum time limitation provides the lowest loss probability and assembly delay time as compared to conventional techniques. Estimation results show that burst buffering delay is reduced and needless bandwidth reservation is prevented. The hybrid approach utilizes Latest Available and First Fit Unused Channel with Void Filling (LA-FFVF) scheduling algorithm for resource reservation. Results represent a good trade-off between burst blocking performance and scheduling time.
