Title: High delay link determination method and apparatus, and route distribution method and apparatus
Inventor: LIU GUOLIANG
IPC: H04L45/121
Filed: 2020-10-12
Abstract: Disclosed in an embodiment of the present application is a high delay link determination method. Whether a link between a first PE and a second PE is a high delay link can be determined by the first PE, wherein the second PE is the next hop of the first PE. Specifically, when an actual delay corresponding to the link between the first PE and the second PE is determined by the first PE, the first PE can determine whether the link is a high delay link by comparing the actual delay with a first delay threshold value. When the actual delay is greater than or equal to the first delay threshold value, it means that the foregoing actual delay exceeds an upper delay limit corresponding to the link between the first PE and the second PE, such that the first PE can determine the link to be a high delay link. In this way, there is no need to wait for a network administrator to determine whether the link between the first PE and the second PE is a high delay link. After the first PE determines the actual delay corresponding to the link between the first PE and the second PE, whether the link between the first PE and the second PE is a high delay link can be determined in time.
