The invention provides a method for switching a communication link and a receiving end. The method comprises the steps of using the receiving end to receive the communication data sent by a sending end, if the communication data is sent by the first sending end, clearing a first timeout count corresponding to the first sending end, and adding 1 to a second timeout count corresponding to the secondsending end; if the communication data is sent by the second sending end, clearing the second timeout count, and adding 1 to the first timeout count; and determining that the communication link withthe first sending end or the second sending end is a working communication link according to a timeout counting threshold, the first timeout count and the second timeout count. In the scheme, when thereceiving end receives the communication data sent by the sending end, the timeout count of the sending end is cleared, 1 is added to the timeout count of the other sending end, and the communicationlink with the first sending end or the second sending end is determined to be the working communication link according to the timeout counts of the two sending ends. When the working communication link breaks down, the working communication link can be quickly switched to another communication link, and therefore the normal communication work is guaranteed.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method for switching a communication link and a receiving end. Background technique [0002] In application scenarios that require high availability of communication, 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: the receiving end selects a communication link as the data source according to the default setting, as long as it continues to receive the data transmitted by the selected communication link, it will not switch the communication link. After the selected communication link times out, the communication link will be switched. However, since the time for detecting communication timeout is long and much longer than the transmission period of ...
