A method, a device, and a system for offloading network traffic are provided, which are applied in the field of mobile communications. An offloading device located before a Serving General Packet Radio Service Support Node (SGSN) receives a data stream of a user sent by a base station, obtains an offloading policy of the user from the offloading device and/or obtains the offloading policy of the user from a policy server, and forwards the data stream according to the offloading policy. Accordingly, the offloading device can obtain the corresponding offloading policy according to the data stream sent by a forwarding plane, send a data stream of low value, low real-time performance requirement, or low priority to the Internet or another specific networks, and send a data stream of high value, high real-time performance requirement, or high priority to high-value devices, thereby reducing the networking cost.

Method, device and system for offloading network traffic

The invention discloses a method for implementing link state passing-through in network, for informing the peer of link fault, including: the service device detecting whether there is a link fault in the network; in case of link fault, the service device transferring link fault information to peer service device with a control frame; in response to the control frame containing link fault information, the peer service device disconnecting the user's link and performing corresponding processes; the user at the faulty peer communicating with peer user through the spare network; when the link recovers to normal, the service device at the recovery peer sending a control frame containing link fault recovery information to peer service device to reestablish communication between the users on the link. The invention is capable of reducing extra overhead under normal network conditions as much as possible.
