Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
According to the application, when the node communication is abnormal, a communication detection signal is sent to the node, and when the response information is not received within the preset time, the node is judged to have a fault, and the target node is selected from the rest nodes, so that the communication task of the node is taken over, and the stability of the cluster communication is improved.
In order that the above-described aspects may be better understood, exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
Example 1
In the audio and video communication process, the signaling negotiation is carried out, the media transmission only supports memory level backup, communication abnormal faults are easy to occur, for example, telephone software and an IP telephone interface display call are caused, but no sound phenomenon exists, and the automatic recovery is avoided. Although the audio and video platform generally supports the cluster, the problem of call recovery still cannot be solved when a single service fails. In order to quickly recover communication and improve stability of trunking communication, an embodiment of the present application provides an abnormal communication recovery method, and referring to fig. 1, fig. 1 is a schematic flow chart of a first embodiment of the abnormal communication recovery method of the present application.
In this embodiment, the abnormal communication recovery method includes:
Step S10: judging that the first node has a fault when response information of the first node based on the communication detection signal is not received within preset time, and acquiring signaling and media information of the first node from a database;
In this embodiment, the communication service adopts a cluster manner to deploy the communication server, and each node corresponds to at least one service device, i.e., a node server. Communication nodes in the cluster can communicate with each other. Each communication node comprises a signaling system, a media system and a sentinel. The signaling system can monitor, select and operate the communication according to the signaling of the communication node, the media system can complete the information transmission function in the communication process according to the media information, and the whistle can monitor the signaling system and the media system to ensure the normal operation of the signaling system and the media system. In addition, the node servers of the respective communication nodes in the cluster share a database. The database stores signaling and media information for all nodes.
In the implementation, when the response information of the first node based on the network detection signal is not received within a preset time, a sentinel in the communication node can judge that the first node has a fault, and the state is network abnormality and/or equipment abnormality. The sentinel will obtain the signaling and the media information of the first node in a cluster database shared by the clusters.
Alternatively, the time of signal transmission may be different due to the different distances between the different nodes. In order to ensure the quick recovery of abnormal communication, in the cluster, the sentry most quickly determining that the first node has a fault acquires signaling and media information of the first node in a database, and marks information corresponding to the first node in the database so as to avoid repeated acquisition of other sentries. It should be noted that, the first node is a node corresponding to communication detection in the cluster, and the second node is another communication node except the first node in the communication cluster.
Step S20: selecting look target nodes from the second nodes based on a preset election algorithm;
In this embodiment, the communication node may send an election signal to all the sentinels of the second nodes in the cluster via the sentinels. And returning an election response to the communication node initiating the election when the sentinel of the second node receives the election signal and when the load of the corresponding second node is smaller than the preset load. The election response comprises the load of the corresponding second node and the real-time operation parameters of the signaling system and the media system.
Specifically, the communication node may directly select the target node according to the load condition of the second node, or may score the second node through a weighted summation algorithm, so as to select the target node according to the scoring result.
As an alternative embodiment of electing the target node, the communication node initiating the election may choose the target node based on the load of the second node. After receiving the election response, the communication node may determine a load of the second node according to the election response, determine the second node with the smallest load, and select the second node as the target node.
As an alternative embodiment of the election target node, the communication node may also score each second node according to the election response. The communication node may calculate the weight according to the preset weight, for the real-time operation parameter of the signaling system, the real-time operation parameter of the media system, and the load, respectively. By summing the weights, a final score for each second node may be determined. The score may more fully evaluate the communication processing capability of the second node. The communication cluster may select the target node based on the score.
Step S30: and sending the signaling and the media information to the target node, wherein the target node performs communication recovery based on the signaling and the media information after receiving the signaling and the media information.
In this embodiment, after determining the target node, the communication node sends the acquired signaling and media information to the signaling system and the media system of the target node through the sentinel respectively.
Further, when the communication node initiating the election is selected as the target node, the sentinel in the communication node will send signaling and media information to the signaling system and media system of the communication node.
For example, after any communication node in the cluster is selected as a target node and receives signaling and media information, the received signaling and media information is identified, and the communication information is reloaded according to the signaling and the media information. In addition, the sentinel of the node can acquire the IP address of the first node in the database shared by the clusters, and reconstruct a monitoring network of signaling and media information according to the IP address.
According to the embodiment of the application, when the node communication is abnormal, the communication detection signal is sent to the node, and when the response information is not received within the preset time, the node is judged to have a fault, the target node is selected from the rest nodes, and the communication task of the node is taken over, so that the communication recovery speed is improved, and the stability of cluster communication is improved.
Example two
Based on the same inventive concept, the present application also provides a second embodiment, referring to fig. 2, fig. 2 is a schematic flow chart of a second embodiment of the abnormal communication recovery method of the present application.
In this embodiment, when the response information of the first node based on the communication detection signal is not received within the preset time as in step S10, it is determined that the first node has a fault, and before the signaling and the media information of the first node are acquired in the database, the method further includes:
step S11: monitoring a signaling system and a media system in a current node, and acquiring real-time operation parameters of the signaling system and the media system;
Step S12: and sending the heartbeat signal to all communication nodes in the cluster based on a preset time period and the real-time operation parameters.
In this embodiment, the sentinels of each node in the cluster are deployed in a one-to-one correspondence with the signaling system and the media system, and are configured in one or more servers. Each sentinel monitors the signaling system and the media system in the current node, and real-time operation parameters of the signaling system and the media system are obtained in real time, so that normal operation of communication is ensured.
In specific implementation, in order to prevent failure of the server from causing monitoring failure of the sentry, the sentry needs to generate a heartbeat signal according to real-time operation parameters of the signaling system and the media system based on a preset time period, and send the heartbeat signal to all communication nodes in the cluster, so that information of normal operation of communication is transmitted to the cluster.
In the embodiment of the application, the communication service monitors the signaling system and the media system of the current node through the whistle on the basis of cluster deployment and sends heartbeat signals to all communication nodes in the cluster at regular time, thereby ensuring the normal operation of communication.
Since the system described in the second embodiment of the present application is a system for implementing the method in the first embodiment of the present application, based on the method described in the first embodiment of the present application, a person skilled in the art can understand the specific structure and the modification of the system, and therefore, the description thereof is omitted herein. All systems used in the method according to the first embodiment of the present application are within the scope of the present application.
Example III
Based on the same inventive concept, the present application also provides a third embodiment, referring to fig. 3, and fig. 3 is a schematic flow chart of a third embodiment of the abnormal communication recovery method of the present application.
In this embodiment, when the response information of the first node based on the communication detection signal is not received within the preset time as in step S10, it is determined that the first node has a fault, and before the signaling and the media information of the first node are acquired in the database, the method further includes:
step S13: determining real-time operation parameters of a signaling system and a media system of a node corresponding to the heartbeat signal according to the received heartbeat signal;
step S14: judging that the first node is abnormal when the heartbeat signal of the first node is not received in preset heartbeat time or the operation parameter of the heartbeat signal is abnormal;
Step S15: a communication detection signal is transmitted to the first node.
In this embodiment, the communication node receives heartbeat signals sent by other communication nodes, and determines real-time operation parameters of the signaling system and the media system in the corresponding node according to the heartbeat signals. The communication node can judge whether the signaling system and the media system are operated normally or not according to the real-time operation parameters.
Specifically, when the heartbeat signal of the first node is not received within the preset heartbeat time or the operation parameter of the heartbeat signal is abnormal, the communication node judges that the first node is abnormal and sends a communication detection signal to a sentinel of the first node. The sentinel of the first node will return corresponding response information based on the communication detection signal. If the response information of the first node based on the communication detection signal is received, the normal working state of the sentry is indicated, the operation of the signaling system and the media system is abnormal, and if the response information of the first node based on the communication detection signal is not received, the first node cannot respond to the communication detection signal, and the first node has the problem of network failure or equipment failure.
Illustratively, when a sentinel detects that a node is abnormal, a ping request is sent to the abnormal node to determine whether the node is a system fault or a network fault, and by the sentinel responding to the ping according to whether the abnormal node is responding to the ping, the reason of the abnormality of the abnormal node can be speculated, and corresponding actions can be taken.
In the embodiment of the application, the communication node determines the running state of the first node through the heartbeat signal, and diagnoses the abnormal state of the first node by sending the communication detection signal when the running state of the first node is abnormal, so as to determine the abnormal communication reason of the first node.
Since the system described in the third embodiment of the present application is a system for implementing the method of the first embodiment of the present application, based on the method described in the first embodiment of the present application, a person skilled in the art can understand the specific structure and the modification of the system, and therefore, the description thereof is omitted herein. All systems used in the method according to the first embodiment of the present application are within the scope of the present application.
Example IV
Based on the same inventive concept, the present application also provides a fourth embodiment, referring to fig. 4, and fig. 4 is a schematic flow chart of a fourth embodiment of the abnormal communication recovery method of the present application.
In this embodiment, the signaling and the media information are sent to the target node as in step S30, where after the target node receives the signaling and the media information, after performing communication recovery based on the signaling and the media information, the method further includes:
step S31: when receiving the communication detection signals sent by other communication nodes, determining real-time operation parameters of the signaling system and the media system, and sending the response information to the communication nodes based on the real-time operation parameters;
step S32: when the real-time operation parameters of the signaling system or the media system are abnormal and not recovered within the preset time, replacing the target IP address of the current node with an abnormal server IP, and controlling the restarting of the signaling system and the media system;
Step S33: and executing the step of selecting the target node in the second node based on the preset selection algorithm.
In this embodiment, when the sentinel receives the communication detection signals of other communication nodes, it is described that the communication node determines that there is an abnormality in the signaling system and the media service of the current node. The sentinel transmits the real-time operating parameters to the communication node based on the real-time operating parameters of the signaling system and the media system.
In particular implementations, the sentinel needs to make further acknowledgements to the signaling system and media services of the current node. When the real-time operation parameters of the signaling system or the media system are abnormal and are not recovered within the preset time, the signaling system and the media system are controlled to restart, and the target IP address of the target server is replaced by the abnormal server IP, so that the receiving of the communication is temporarily stopped.
When the sentinel determines that the signaling system and the media service operation parameters of the current node are abnormal, the sentinel of the current node initiates the election process of the target node. It should be noted that the method is equally applicable to the monitoring of the operation of signaling systems and media services by the sentry.
Optionally, the real-time operation parameter abnormality of the signaling system or the media system is determined at the sentry, and the signaling system or the media system can be reset through a reset mechanism provided in the communication node.
Since the system described in the fourth embodiment of the present application is a system for implementing the method of the first embodiment of the present application, based on the method described in the first embodiment of the present application, a person skilled in the art can understand the specific structure and the modification of the system, and therefore, the description thereof is omitted herein. All systems used in the method according to the first embodiment of the present application are within the scope of the present application.

Based on the same inventive concept, the present application also provides a fifth embodiment, referring to fig. 5, and fig. 5 is a schematic flow chart of a fifth embodiment of the abnormal communication recovery method of the present application.
In this embodiment, when the real-time operation parameters of the signaling system or the media system are abnormal and not recovered within the preset time as in step S32, the method further includes, after replacing the target IP address of the target server with the abnormal server IP and controlling the restarting of the signaling system and the media system in the current node:
step S34: after the signaling system and the media system are restarted, determining the running states of the signaling system and the media system in the target server;
Step S35: and when the running state is normal, sending a communication recovery signal to the target node, and replacing the abnormal node IP of the current node with the target IP address.
In this embodiment, after the signaling system and the media system are reset or restarted, the communication node determines, through the sentinel, whether the operation states of the signaling system and the media system are normal. When the running state is normal, the sentinel sends a communication recovery signal to the target node, and replaces the current abnormal node IP with the target IP address so as to recover the communication of the current node.
Optionally, when the signaling system and the media system are reset or restarted and the running state is still abnormal, the sentinel can reset or restart the signaling system and the media system again and send prompt information to the management terminal.
