Abstract

The invention discloses a link detection method and device, wherein the method includes: a local device sends a link detection message to a peer device, wherein the link detection message carries the state of the local device; The local device judges whether it receives a reply message of a link detection message sent by the peer device or a message indicating a link failure within the first predetermined time period, wherein the reply message carries the link detection message of the peer device If the local device does not receive a reply message or a message indicating that the link has failed within the first predetermined time period, it is determined that the link between the local device and the peer device is faulty. The present invention solves the problem that the link detection method in the CDN system in the related art may fail, and improves the reliability of the link detection.

Description

technical field [0001] The present invention relates to the communication field, in particular to a link detection method and device. Background technique [0002] The overall technical direction of triple play requires building a reasonable system architecture, realizing end-to-end standardization, improving user experience, and combining new technologies. Driven by the development trend of triple play integration, the IP MAN needs to be able to carry a wealth of self-operated high-quality services, such as IPTV, virtual private network, Ethernet leased line, etc., while providing users with simple bandwidth services. business experience. Therefore, the key technical points of high-quality service carrying are fast recovery from network faults, security, and stability. [0003] Against this technical background, traditional IPTV services are gradually replaced by new IPTV-related technologies, which is the currently popular converged content distribution network (Content ...
