针对混合交换网络中恒定比特率业务对传输时延要求较高的问题，提出了一种基于滑动窗口的时隙分配方法，通过确定分组在交换网络中的转发时隙位置来决定分组的传输时延。该方法严格约束了输入输出时隙的绝对间隔在一个较小的范围内，保证分组传输时延较小。仿真结果表明，与随机分配法对时隙在整个复帧周期内任意分配相比，采用基于滑窗的分配法能更有效降低传输时延，减小交换缓存容量。

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.
