Abstract: Embodiments of the present disclosure disclose a method for controlling data stream switch and a relevant equipment. The method includes: obtaining bandwidth demand information of a data stream; calculating a BWM according to the bandwidth demand information, the physical bandwidth of at least one ingress port and at least one egress port of the data stream, and TDM service bandwidth information; performing sequencing on entries of the BWM, to obtain a bandwidth sequencing information table; performing cell even sequencing processing on the data stream according to the bandwidth sequencing information table, to obtain a cell table; and controlling, sending of cells of the data stream according to the cell table. Through the solutions provided, processing complexity may be effectively reduced, the problem of scale limitation on a bufferless switch structure is solved, and meanwhile, a delay jitter during switch processing is also decreased.
