Problems solved by technology

However, there are currently the following problems: the PPPoE server disconnects the PPPoE session, but the PPPoE client does not disconnect the PPPoE session, and still sends data packets to the PPPoE server through the PPPoE session. After the PPPoE server receives the data packet, due to the corresponding The PPPoE session has been removed, so data packets will be discarded, resulting in traffic interruption

Abstract

The application provides a session dismantling method and device. The method comprises the following steps: receiving a data message sent by opposite terminal equipment, wherein the data message carries feature information; querying a PPPoE session table according to the feature information; if a session table entry corresponding to the feature information does not exist in the PPPoE session table, constructing a connection interruption message by using the data message; and sending the connection interruption message to the opposite terminal equipment to ensure that the opposite terminal equipment dismantles a PPPoE session between the opposite terminal equipment and local terminal equipment according to the connection interruption message. According to the technical scheme provided by the application, the opposite terminal equipment can dismantle the PPPoE session in time, and thus the opposite terminal equipment can reestablish the PPPoE session with the local terminal equipment, and the network interruption time can be reduced.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for tearing down a session. Background technique [0002] PPPoE (Point-to-Point Protocol over Ethernet, point-to-point protocol based on Ethernet) is an extension of PPP. By establishing a PPPoE session on Ethernet and encapsulating PPP packets in Ethernet frames, it provides The point-to-point connection solves the problem that PPP cannot be applied to Ethernet. Moreover, because PPPoE can combine the economy of Ethernet, the scalability of PPP, and the management and control functions of PPP, PPPoE is widely used in environments such as community access networking. [0003] In a PPPoE network, after the PPPoE client establishes a PPPoE session with the PPPoE server, the PPPoE client sends data packets to the PPPoE server through the PPPoE session, and the PPPoE server sends data packets to the PPPoE client through the PPPoE session. Ho...
