The invention discloses a small cross point buffer high-property crossbar dispatching method for cross points, which mainly comprises queuing technique and a crossbar dispatching algorithm. The small cross point buffer high-property crossbar dispatching method is characterized in that sub groups are stored at input ends and crossbar cross points, the arrived sub groups are divided into cells with fixed lengths and placed into corresponding queues to queue according to objective transfer ports of the sub groups, each cross point is provided with small-capacity buffer so as to decouple matching couplings of input and output, an input end and an output end respectively utilize dispatchers, the input end utilizes a longest queue forecasting mechanism algorithm to select one cell into a corresponding cross point buffer, and the output end utilizes a simple round robin algorithm to select cells in one cross point buffer to output. The dispatching method is stable and high-efficient, is low in complexity, and is adaptable to large-capacity high-speed routers/exchangers.
