Embodiment Construction
[0046]To make the technical solution, objectives and merits of the present invention more comprehensive, the embodiments of the present invention are described in detail with reference to the accompanying drawings.
[0047]In order to reduce flow of data forwarded by a PoP node in a case of maintaining routes by adopting the core-router integrated overlay (CRIO) technology, according to the embodiments of the present invention, multiple PoP groups are set in a transmission network, and one or more PoP nodes are set within each PoP group. PoP nodes within the same PoP group issue routing information of the same super prefix respectively; and PoP nodes within different PoP groups issue routing information of different super prefixes. The PoP nodes within the same group maintain the routing information of the detailed prefix covered by the same super prefix. In this way, when different data packets are transmitted, different PoP nodes within the same group can share load of the data packe...
