Abstract:
1. A method for delaying a burst, comprising: judging, by a core router, whether an overlap of bursts reaches an overlap threshold set for a link to be protected if a Burst Header Packet (BHP) received by the core router indicates that the bursts directed to the link to be protected will be overlapped on the link; if the overlap of the bursts reaches the overlap threshold set for the link to be protected, determing the burst to be delayed, specifying a proper delay length for the burst to be delayed, and reserving the resource for the burst to be delayed; if the overlap of the bursts does not reach the overlap threshold set for the link to be protected, performing no delay processing for the burst; generating a corresponding BHP according to the reserved resource; sending the generated BHP to a downstream core router; and sending the burst to be delayed to the downstream core router by scheduling the reserved resource after receiving the burst.
