Embodiment Construction

[0024] The embodiment of the present invention aims at the defect that the backup network port of the network device of the main and backup network ports cannot be realized in the network layer path state detection, and proposes a method, device and system for path state detection to detect the network of the backup network port. Layer path status, to avoid the problem that when the network layer of the standby network port fails, the main and standby equipment will be switched back and forth continuously, and the system reliability will be affected.

[0025] The active and standby network port devices described in the embodiment of the present invention can be CSCF, HSS, ATS, RM9900, MRF6600, CCF, DNS and other service network elements in the MSC and IMS product families. Products, SGSN and other equipment, as long as they are equipment with primary and backup network ports, no matter they are equipment supporting IPv4 or equipment supporting IPv6, they can be implemented acco...

Abstract

The invention discloses a method, equipment and a system for detecting path status. Aiming at the problem that the standby path status of the main standby gateway equipment cannot be tested in the prior art, the invention provides the method, the equipment and the system for detecting the path status; a detection message on the standby path status of the main standby gateway equipment is transmitted, the source IP address in the detection message is configured as a preset IP address that is not used for communication, so that the receiving equipment of the detection message does not need to change the current service path, namely, the communication path between the main gateway of the main standby gateway equipment and the receiving equipment does not need to be changed, furthermore, the path status detection of the standby gateway can also be carried out simultaneously, so that the path status of the standby gateway can be acquired in time, therefore, the reliability of the system isincreased and no special IP detection address for the standby gateway is needed; in addition, the IP resource can be saved, the possibility of IP address collision cannot be caused, thus realizing the simple and reliable detection of the path status.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method, device and system for path state detection. Background technique [0002] In a communication network, in order to increase the reliability of the system, communication devices are usually configured with active and standby network ports. The IP addresses of the active and standby network ports of the device configured as the active and standby network ports are the same. Under normal circumstances, the IP address on the primary network port is enabled, and the Media Access Control (MAC, Media Access control) address of the peer IP can be detected through the Address Resolution Protocol (ARP, Address Resolution Protocol), and the IP address on the standby network port is disabled. The network port cannot send IP and ARP packets, nor accept these packets; when the path of the primary network port fails, the backup network port will be activated. [0003] In the fie...
