NETWORK SWITCHING DEVICE AND TIME SLOT EXCHANGE METHOD

A network switching device and a time slot exchange method are used for solving the technical problem that the hardware consumption of the existing crossbar switching architecture is too high. The network switching device comprises a processor, N ports, at least N memories, each of the memories corresponding to one of the ports. The memory is used for storing traffic data received by the corresponding port at each time slot. The memory comprises a plurality of storage areas, each of which stores the traffic data received by the port at one time slot corresponding to the storage area. The processor is used for exchanging traffic data stored in the at least N memories respectively among each of the ports during the exchange cycle. The exchange cycle comprises a plurality of time slots. In each of the time slots, the processor controls each of the storage areas of the memory to be written a piece of traffic data or to be read a piece of traffic data. 种网络交换设备及时隙交换的方法，用以解决现有的Crossbar交换架构的硬件消耗过高的技术问题。该网络交换设备中包括处理器，
