Abstract

The embodiment of the invention discloses a method and equipment for network duplicate removal. The method comprises the following steps: receiving grouping from an incoming interface; acquiring an outcoming interface according to a destination address of the grouping; carrying out duplicate removal on the grouping according to the outcoming interface; and switching the grouping after duplicate removal from the incoming interface to the outcoming interface. By adopting the technical scheme provided by the embodiment of the invention, the problems that flow duplicate removal of interior of network equipment and an interface line card can not be realized in the prior art, and the cache utilization rate of the network equipment is low are solved.

Description

technical field [0001] The present invention relates to the field of network communication, in particular to a method and equipment for deduplication in a network. Background technique [0002] There is a large amount of repeated content in the data packets transmitted on the network link, and the transmission of the repeated content not only occupies link bandwidth resources, but also reduces network transmission efficiency. Usually, the network deduplication (duplicate removal) technology is to deploy the deduplication function at both ends of the link, that is, the deduplication function is deployed on the outbound interface of the upstream network device and the inbound interface of the downstream network device. In this way, for the scenario where network traffic is transmitted in point-to-multipoint mode, the deduplication function needs to be deployed on multiple outgoing interfaces of the upstream network device, and the cache utilization rate of the upstream network...
