The present invention provides a method for switching a communication link and a receiving end. The receiving end receives the communication data sent by the sending end; if the communication data is sent by the first sending end, the first timeout count corresponding to the first sending end is cleared, and the The second timeout count corresponding to the second sender is increased by 1; if the communication data is sent by the second sender, the second timeout count is cleared and the first timeout count is increased by 1; according to the timeout count threshold, the first timeout count and the first timeout count Two timeout counts to determine that the communication link with the first sending end or the second sending end is a working communication link. In this solution, when the receiver receives the communication data sent by the sender, it clears the timeout count of the sender and increments the timeout count of the other sender by 1. According to the timeout counts of the two senders, it is determined that the communication link with the first sender or the second sender is a working communication link. When the working communication link fails, it can quickly switch to another communication link, thereby ensuring normal communication work.
Description
technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method for switching a communication link and a receiving end. Background technique [0002] In an application scenario that requires high availability of communication, a redundant configuration of communication links is usually adopted, that is, when a working communication link fails, the redundantly configured communication link undertakes the communication work. [0003] The current communication link redundancy configuration method is as follows: the receiver selects a communication link as the data source according to the default settings. As long as the data transmitted by the selected communication link is continuously received, the communication link will not be switched. The communication link is switched after the selected communication link communication times out. However, since the time for detecting the communication timeout is long and mu...
