ABSTRACT:
A method, system, and device for maintaining routes are provided. A communications network includes multiple point of presence (PoP) groups, where each of the PoP groups includes one or more PoP nodes. PoP nodes within the same PoP group issue routing information of the same super prefix. PoP nodes within different PoP groups issue routing information of different super prefixes. The method further includes the following steps. A PoP node acquires routing information of a detailed prefix covered by a super prefix issued by the PoP node and synchronizes the routing information of the detailed prefix with other PoP nodes within the same PoP group. The method, system, and device reduce flow of data forwarded by each PoP node.
