Embodiment Construction

[0046] In the embodiment of the present invention, the first device adds reply address information in the path tracing request message received from the external network device, and the second device can know to send the path tracing reply message according to the reply address information in the path tracing request message. The packet is sent to the first device, so that the external network device can track the forwarding path of the packet in the network that needs to be switched, thereby improving the efficiency of network maintenance and management.

[0047] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0048] Such as figure 1 As shown, the system for processing path tracing request packets in this embodiment of the present invention includes: a first device 10 and at least one second device 20 .

[0049] The first device 10 is configured to encapsulate the first network header of the pa...

Abstract

The invention relates to the field of communication, in particular to a method, a system and a device for processing a path tracking request message to solve the problem that extranet equipment cannot track the message in forward paths in a network needing label switching in the prior art. The method comprises the following steps that: first equipment encapsulates a first network packet header of a received path tracking request message sent by the extranet equipment, arranges replay address information in the path tracking request message, sets the survival time of the first network packet header, and continues to send the path tracking request message; and second equipment receiving the path tracking request message of which the survival time of the first network packet header is equal to a preset value generates a path tracking reply message, takes the self loopback address as a source address of the path tracking replay message, and returns the path tracking replay message according to the reply address information. The method improves the efficiency of maintaining and managing the network.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, system and device for processing path tracing request messages. Background technique [0002] With the rapid development of the network, there are more and more devices in the network, and the sending end needs to pass through multiple devices to transmit a message to the receiving end. If a device does not work properly during the transmission process, the message cannot be successfully transmitted. At this time, it is necessary to quickly and accurately locate which device has the problem. It will undoubtedly take a lot of manpower and material resources to check each device manually, so tracking the path has become the fastest way for network maintenance. [0003] The current tracking method of IP (Internet Protocol, Internet Protocol) network: [0004] The device A end constructs an Echo Request (reply request) message (the source IP address is the IP address of the devi...
