Embodiment Construction

[0041] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the networking structure applicable to the embodiments of the present invention will first be described below.

[0042] See figure 2 , which is a schematic diagram of a traffic forwarding networking architecture provided by an embodiment of the present invention, as shown in figure 2 As shown, in this networking, the switch establishes a connection with the MEC through an interface group (also called a service loopback linkage group), and a connection is established between the switch and the EPC. Wherein, the interface group may include an outlet interface and a return port.

[0043] exist figure 2 In the shown network, the traffic diversion rule corresponding to the interface group can be configured on the switch. When the switch receives traffic from the eNodeB (base station) side, the traffic that matches the traffic diversion ru...

Abstract

The invention provides a traffic forwarding method and apparatus. The method comprises the following steps: periodically sending a detection message to an MEC through an outbound interface in an interface group; if the detection message is not received from a loopback interface of the interface group within a preset time, determining a traffic diversion rule corresponding to the interface group asan invalid state, wherein the traffic diversion rule corresponding to the interface group is used for forwarding the traffic matching the traffic diversion rule to the MEC through the interface group; and when the traffic is received from an eNodeB side, and it is determined that a target traffic diversion rule in the valid state matching the traffic does not exist, forwarding the traffic according to a local forwarding table entry. By application of the traffic forwarding method and apparatus provided by the embodiment of the invention, the reliability of networking can be improved.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a traffic forwarding method and device. Background technique [0002] MEC (Mobile Edge Computing, Mobile Edge Computing) is a key technology for the evolution of 5G (fifth generation mobile communication network). By deploying computing, storage, distribution, big data analysis and other functions in the wireless edge network, 4G (fourth generation mobile communication network) & 5G mobile network capabilities can be opened to Internet applications. The above-mentioned network deployment makes traditional wireless networks closer to users and carries localized services, thereby improving user experience and giving full play to the value of edge networks. [0003] At present, the schematic diagram of the network architecture for deploying MEC technology in the network can be as follows: figure 1 As shown, in this network, when the MEC fails, the switch will...
