Abstract: Embodiments of the present invention provide a data transmission method, a forwarding information update method, a communications device, and a controller. The communications device includes: a forwarding module and one or more interfaces, where the forwarding module receives a data packet sent to a receive end; determines, according to a correspondence between data filtering template information of the data packet and interface information in forwarding information maintained by the forwarding module, an interface for forwarding the data packet to the receive end, where if data packet transmission is performed by using a specific radio access technology between the communications device and a next hop to which the communications device forwards the data packet, the interface is an interface corresponding to the radio access technology; and forwards the data packet to the interface; and the interface receives the data packet sent by the forwarding module, and forwards the data packet.

Abstract: A solution to deduplication in a storage system is disclosed herein. In this solution, a controller stores, at a first storage address, a data block that is written for the first time, and inserts, in a fingerprint table, a first fingerprint of first data that is written for the first time, but does not establish a mapping relationship between the first fingerprint and the first storage address. When receiving subsequently written second data to be written, the controller allocates a second storage address to the duplicate second data, stores the second data at the second storage address, and establishes a mapping relationship between the first fingerprint and the second storage address in the fingerprint table. This reduces an amount of data in the fingerprint table.
