Method for monitoring and maintaining multi-data link

Abstract

The invention discloses a multiple-data link monitoring and maintaining method, comprising: setting basic timers and establishing at least a timer queue. When the basic timers reach the timing every time, it separately detects each to-be-monitored link in all current timer queues to be processed and determines whether the link normally transmits and receives data: if the link is transmitting data, it will not detect until the timer of the link reaches the timing again; if the link does not transmit data, sending handshake data packet; if the data is normally received by the link, not detecting until the timer reaches the timing again; if no data is received by the link, recording corresponding information and reporting alarm information if need be. And it can largely reduce link transmission and increase equipment capacity.

Description

technical field [0001] The invention relates to link maintenance technology, in particular to a method for monitoring and maintaining multiple types of data links with multiple links in each type. Background technique [0002] In a communication network, all network devices must be connected through links to complete communication and information exchange between network devices. Usually, for each link, especially the important data link, such as the RNC inter-office signaling link in 3G, it is necessary to confirm whether the status of each link is normal in real time, so as to ensure the normal operation of network equipment and the entire communication system . Here, the link refers to a point-to-point data path, which can be a link directly connected between two network devices, or a link passing through multiple network device nodes in the middle; the link can be a link that supports Physical links of various protocols, such as AAL5 and AAL2 of Asynchronous Transfer M...

Problems solved by technology

Generally, the length of the data packet sent for transmitting the handshake signal is very short, but in order to ensure the real-time performance of the detection, the sending time interval is also very short, that is to say, it needs to be sent more frequently on the detected data link. The handshake signal, in this way, will increase the signal transmission volume of the data link, especially with the rapid development of the communication network, the number of links to be monitored is increasing, resulting in a sharp increase in the transmission volume of the handshake signal. In addition, the frequent sending and receiving and detection of short data packets such as handshake signals will consume and occupy more CPU processing power, making it difficult to greatly increase the capacity of the device

[0004] In addition, the current detection method of the handshake mechanism monitors each link independently, and there is no unified management, so resources will be wasted
