Embodiment Construction

[0036] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] figure 1 It shows the relationship among the management workstation (NMS, hereinafter referred to as NMS), the managed network element (where a management agent is installed) and the SNMP protocol in the SNMP system. This system is a well-known technique in the art, and will not be repeated here.

[0038] figure 2 It shows the change diagram of the four connection states set by the NMS for the central office equipment. The four states are: not connected, connected normally, interrupted, and connected abnormally, where:

[0039] Unconnected means the connection state of the central office device initialization, which means that the device is waiting to update the connection state;

[0040] The normal connection means that the NMS and the central office equipment have been connected, and the normal connection status can only change to...

Abstract

The invention discloses a method for detecting the connection status of central office equipment in an SNMP network management system. The operating status of the central office equipment is set to four states: unconnected, normal connected, abnormally connected and interrupted. The terminal device sends heartbeat packets asynchronously, and sets the above four connection states of the central office device according to the heartbeat response returned by the central office device. The present invention obtains the connection state of the central office equipment through the heartbeat packet and the heartbeat response packet, supports concurrent processing of the judgment of the connection state of a large number of devices, and the judgment of the state between the devices does not affect each other, so as to avoid damage to the equipment when the network state is not good Misjudgment of the operating status can reflect the actual operating status of the device more realistically, and at the same time make a trade-off between the time interval for sending heartbeat packets to avoid frequent polling and increase the overhead of the device and network.

Description

technical field [0001] The invention relates to a network system based on SNMP, in particular to a detection method for the connection state of central office equipment in the SNMP network management system. Background technique [0002] At present, the network technology is changing with each passing day, the user scale of the broadband access network is constantly expanding, and the complexity of the network is also increasing. To ensure the normal operation of the network objects (routers, switches, lines, etc.) The workload of operation, maintenance and management such as network topology is also increasing. Therefore, the network management system is becoming more and more independent, more complex, and more complete in function. Network management has also developed into an important branch of computer network, and gradually becomes standardized and institutionalized. At present, the Simple Network Management Protocol (SNMP) has become a de facto industry standard in ...
