Abstract: This application provides example traffic balancing methods, network devices, and electronic devices, and relates to the field of communications technologies. An example electronic device can create or maintain a first flowpac, and classify a packet that uses a first node as a destination into the first flowpac. When a network balancing parameter meets a preset condition, a second flowpac is created or maintained. A subsequent packet that uses the first node as a destination is classified into the second flowpac, where packets belonging to a same flowpac have a same destination node and a same sending path, and a sending path of a packet in the second flowpac is different from a sending path of a packet in the first flowpac.

Abstract: The present disclosure provides a switch fabric system, the system including M first crossbar units (CUs) and N second CUs, where each first CU includes L first input ports, a first arbiter, a first crossbar, and N first output ports. Each second CU includes M second input ports, a second arbiter, a second crossbar, and one second output port. M×N first output ports of the M first CUs are respectively coupled to N×M second input ports of the N second CUs, where N first output ports of each first CU are respectively coupled to and in a one-to-one correspondence with one second input port of each second CU in the N second CUs. In the example system, N equals M×L, and M, N, and L are all positive integers.

The method includes: obtaining, by a first sending end, a first timestamp compensation time; adding, by the first sending end, the first timestamp compensation time to a first timestamp carried in a first cell, where the first timestamp is a sending time of the first cell; and sending, by the first sending end to a receiving end, the first cell that is added with the first timestamp compensation time, so that the receiving end forwards the first cell according to the first timestamp that is added with the first timestamp compensation time. In the present invention, a first timestamp compensation time is added to a first timestamp carried in a first cell, which improves cell forwarding efficiency of the receiving end and prevents the occurrence of cell accumulation in a link.
