Abstract:

For solving the problem that the CBR services have a large transmission delay through the hybrid switching networks, a sliding window-based time slot allocation method is proposed, which can decide the packet transmission delay by determining the CBR packets' slot position in the switching network. This method strictly constraints the absolute interval in a smaller range between the input and output time slots to ensure the packets' smaller transmission delay. Simulation results show that compared with the random allocation method, the sliding window-based allocation method can reduce the transmission delay effectively and the switching cache capacity.

Key words: hybrid switching network, sliding window, time slot allocation, delay
