Problems solved by technology

[0004] 1. It is difficult to set the heartbeat cycle
[0005] The length of the heartbeat cycle is generally set artificially, but this cycle is often difficult to meet various application scenarios
If the network management system uses a fixed heartbeat cycle, it may weaken the availability of the network management system
[0006] 2. The impact of heartbeat packets on the performance of the network management system
If faults such as link anomalies need to be detected in time, the frequency of sending heartbeat messages must be increased. The network management needs to frequently process heartbeat detection data, which affects the efficiency of the network management, and the frequency of sending heartbeat messages is too high, which will increase the burden on the network. Seriously, it will cause network paralysis

[0047] In the first embodiment of the present invention, an adaptive method for a heartbeat cycle, such as figure 2 shown, including the following specific steps:

[0048] Step S101, within a set time, calculate a reference heartbeat period according to network load conditions.

[0049] Specifically, within the set time, a reference heartbeat period is calculated for the network element load carried in each heartbeat message combined with the network management load condition, and the reference heartbeat period is set as T 1 , the current heartbeat period is T, and the calculation method is as follows:

[0050] in a and b respectively represent the values ​​of the load status of the current network management and network elements, a' and b' respectively represent the values ​​of the load conditions of the network management and network elements when the last heartbeat message was received, 0≤a, b, a', b '≤1, the value of the network management load status is the actual ...

[0062] In the second embodiment of the present invention, an adaptive device for a heartbeat cycle, such as image 3 As shown, it includes the following components:

[0063] The reference heartbeat period calculation module 10 is used to calculate the reference heartbeat period according to the network load within a set time.

[0064] Specifically, the reference heartbeat cycle calculation module 10 calculates a reference heartbeat cycle for the network element load situation carried in each heartbeat message in combination with the network management load situation within a set time, and the reference heartbeat cycle is set as T 1 , the current heartbeat period is T, and the calculation method is as follows:

[0065] in a and b respectively represent the values ​​of the load status of the current network management and network elements, a' and b' respectively represent the values ​​of the load conditions of the network management and network elements when the last heartb...

[0075] The third embodiment of the present invention, this implementation is based on the first and second embodiments, combined with the example of handshake and heartbeat detection between the network management system and the network element in the network management system, introduces the self-adaptive process of the heartbeat cycle in detail, details as follows:

[0076] 1. The handshake process between the network management system and the network elements includes the following steps:

[0077] A1. The network management initiates a link establishment command based on TCP (Transmission Control Protocol) and actively queries network element devices;

[0078] A2. Determine whether the network element can be used normally. If it can be used normally, the network element will feedback the link building command, and start sending heartbeat messages based on UDP (User Datagram Protocol, User Datagram Protocol), and enter step A6. If If it cannot be used normally, go to step A...

Abstract

The invention discloses an adaptive method and device for a heartbeat cycle. Within a set time, a reference heartbeat cycle is calculated according to network load conditions; based on the deviation of the reference heartbeat cycle itself and the deviation between the reference heartbeat cycle and the current heartbeat cycle Determine whether the current heartbeat period needs to be recalculated; after recalculating the current heartbeat period, when the network is not in a congested state, enable the recalculated current heartbeat period. The invention realizes the dynamic adjustment of the sending period of the heartbeat message, and avoids the influence of important services caused by the inappropriate setting of the sending period of the heartbeat message when the network manager or network element is overloaded. At the same time, it avoids the waste of bandwidth and system resources caused when the heartbeat cycle does not adapt to the network conditions, and the impact on network management performance.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a heartbeat period self-adapting method and device. Background technique [0002] In the network management system, the network management server (referred to as the network management) and the network element equipment (referred to as the network element) managed by the network can communicate through the network management to check the network elements, or the network elements periodically send heartbeat messages to the network management. link detection. like figure 1 As shown, if the network management system conducts periodic information exchange through the heartbeat message, when the network element is normal, the network element sends a heartbeat message to the network management, and the heartbeat message indicates that the network element is currently in the ready state, and the network management After receiving the heartbeat message, it is considered ...
