Abstract

The invention discloses a link processing method and apparatus. The link processing method comprises: a first terminal device switches on a first member interface of the first terminal device and a second member interface, physically connected with the first member interface, of a second terminal device through execution of a negotiation process; the first terminal device receives a first extension keep-alive message repeatedly transmitted by the second terminal device according to a preset time interval, wherein the first extension keep-alive message comprises first negotiation information and second negotiation information in the second terminal device, and content of the second negotiation information is changed when the second member interface is abnormal; and if the first terminal device determines that the received first negotiation information and the second negotiation information are different from the first negotiation information and the second negotiation information of the first terminal device, the first member interface is switched off. According to the method and apparatus, the problem of poor reliability of links in the link detection method provided in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a link processing method and device. Background technique [0002] High-Level Data Link Control (HDLC for short) is a bit-oriented data link layer control protocol that transmits data on a synchronous network. HDLC can provide transparent point-to-point transmission for upper layer protocols. [0003] Users can realize low-load data transmission and link detection functions through HDLC. Specifically, the packet header of the HDLC protocol only occupies four bytes, so in the case of the same Maximum-Receive-Unit (MRU for short), larger data packets can be transmitted, especially for short packets The transmission of text, such as link detection messages, has greater advantages. HDLC provides a timing detection function for the link, which can be realized through the keepalive message (keepalive message) in the standard protocol. As long as the member interfaces t...
