Description
Technical Field
The invention relates to the technical field of internet, in particular to an island self-healing method of a network system based on an SNMP protocol.
Background
SNMP (simple network management protocol) is currently the most widely used network management communication protocol. With the increase of new hardware chip energy, the SNMP server device manages more and more client devices. These devices may be trans-regional or even boxed, fail to locate efficiently once they fail, affect the user experience, and can be very costly to maintain.
The network system architecture based on the SNMP protocol mainly comprises three parts, namely client equipment, an SNMP agent and SNMP server equipment, forms a complete communication management system, and is widely applied to mobile communication networking and robot cluster networking.
In the operation and maintenance process, uncontrollable faults may occur to main equipment in the network in the process of configuring, modifying parameters or upgrading, and if the client equipment is disconnected from the server or is in single-pass connection, the client cannot be connected with the server, so that an island is formed, a maintainer cannot locate the fault reason at the first time, the user experience of the area where the client equipment is located is influenced, and the operation and maintenance cost is increased. Therefore, it is very important to provide a method for island detection and self-healing.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide an island self-healing method based on an SNMP protocol network system, so as to reduce operation and maintenance cost, efficiently locate faults and recover equipment operation through the self-healing method under certain conditions.
The technical scheme adopted by the invention for realizing the purpose is as follows: an island self-healing method based on an SNMP protocol network system comprises the following steps:

Establishing an inquiry link between each client device and a server, wherein the client device sends a heartbeat packet to the server, the server also sends a heartbeat packet to the client, and the heartbeat packet sent by the client device and the heartbeat packet sent by the server are independent; the client device and the server respectively detect heartbeat packets sent by the opposite side, and if the client device and the server can continuously and stably receive the heartbeat packets sent by the opposite side, the server and the client device are judged to be in normal communication;
(2) sending the modified configuration parameters or the new version to the client
When the server and the client equipment are judged to be in normal communication through the step (1), the server sends a modification configuration parameter or a new version to the client equipment, a heartbeat package is sent to the client equipment after the modification configuration parameter or the new version is sent to indicate that the modification configuration parameter or the new version is sent, the client backs up the original parameter or the original version after receiving the modification configuration parameter or the new version, the client equipment sends the heartbeat package to the server after the backup is finished to indicate that the modification configuration parameter or the new version is received and the original parameter or the original version is backed up, and the client equipment modifies the received configuration parameter or installs the new version after the heartbeat is sent;
(3) client device islanding detection
After the client equipment modifies the received configuration parameters or installs a new version in the step (2), the server continues to send heartbeat to the client equipment, if the client equipment does not receive heartbeat packets sent by the server continuously for multiple times, the disconnection of a direction link from the server to the client equipment can be judged, the client equipment starts a reset timer, and the link is still not recovered within the set time of the reset timer, so that the client equipment is determined to be in an island state;
(4) client device reset and black box information recording
After the client device is subjected to island detection through the step (3), if the client is determined to be in an island state, the client device backs back the backup parameter data and resets the client device to record black box information, the black box information comprises the starting time and the ending absolute time when the heartbeat is lost and the modified configuration parameter and the version information before the reset, a request link between the server and the client device is reestablished, the heartbeat package sent by the client device and the server is ensured to be stably received and sent, the server makes corresponding modification after analyzing the fault reason, and the configuration parameter modification or version upgrading operation is carried out again.
In the step (3), the server sends the heartbeat packet to the client device, and the client device also sends the heartbeat packet to the server, if the server does not detect the heartbeat packet sent by the client device for a plurality of times continuously, the server stops sending the heartbeat packet to the client device, recovers resources, and records the absolute time of the last heartbeat packet.
And (4) in the step (3), the client device and the server do not receive the heartbeat packet sent by the opposite side continuously for 10 times, and the heartbeat packet is used as a standard for judging whether the server and the client device are disconnected.
And (4) the time set by the reset timer in the step (3) is 2 hours.
And (4) the island state in the steps (3) and (4) is that the client equipment and the server equipment lose contact, and the server end cannot perform subsequent maintenance operation on the equipment.
The client device is a device which carries out SNMP protocol communication with the server through an SNMP agent program, and the set distance between the client device and the server is not limited by geography.
The server can be deployed with one or more groups in a network system, manage a large number of client devices, and perform maintenance operations such as parameter configuration, modification, version upgrade, state alarm query, new energy statistics and the like on the client devices.
The heartbeat interval of the heartbeat packet is set to be 1 second, and the network connection between the client device and the server includes but is not limited to a fiber network.
The invention has the beneficial effects that:
1. determining that the server and the client equipment are normally communicated through heartbeat mutual sending detection in the step (1), after the server and the client equipment are normally communicated, sending configuration parameter modification or a new version to the client through the step (2), modifying received configuration parameters or installing the new version by the client equipment, performing island detection on the client equipment with the received configuration parameters or the new version through the step (3), judging whether the client equipment is in an island state, if the client is in the island state, resetting the client equipment and recording black box information through the step (4), and performing corresponding modification after analyzing a fault reason according to the black box information, wherein the whole processing process is simple and efficient, and the operation and maintenance cost is well reduced;
2. by adopting a mutual heartbeat sending mode, the problem of the disconnection of an uplink link and a downlink link can be more accurately analyzed and positioned, wherein the uplink link refers to a client, and the downlink link refers to a link from a server to client equipment, so that the high-efficiency positioning of the fault can be ensured;
3. although the client device enters an island, the service provided for the user is normal, and the link with the server is tried to be restored, so that the influence on the user can be reduced to the minimum, and under the condition that hardware has no problem, the device can be reset, the configuration parameters or versions can be modified in a backspacing mode, the link with the server device is built again to restore the operation, and the operation of the device can be restored by a self-healing method.
