Abstract: The disclosure discloses a method and apparatus for controlling information element switch. The method comprises the following steps: a switch board determines that it has received a link request information element from each ingress line card, wherein the link request information element carries the request time stamp information; the switch board performs link allocation according to each request time stamp information, wherein the link is the link connecting the switch board with each egress line card; and each ingress line card transmits a data information element according to the result of the link allocation. With the disclosure, the problems of time delay and jitter in an information element switch process are solved, the input end flow of the switch board can also be controlled, and the requirement for the egress line card cache and difficulty in data packet recombination are reduced.
