Problems solved by technology

[0007] However, Ping technology is used to detect faults in the existing HSAPN. In the process of realizing the present invention, the inventors found that the Ping command needs to be manually initiated by the network administrator. Commands require a lot of work; moreover, they are only executed when the network administrator thinks it is necessary, so there is no guarantee that all faults will be detected effectively and quickly

Embodiment Construction

[0026] Throughout the description, the preferred embodiments and examples shown should be considered as exemplars of the invention and not intended to limit the scope of protection of the invention.

[0027] The application scenarios of the embodiments of the present invention are as follows figure 1 As shown, including HSAPN network, packet switching network (for example, IP network, ATM network or FR network) and border entity (E.D) equipment, HSAPN network communicates with IP network, ATM network or FR network through E.D equipment, in HSAPN network All equipment and E.D equipment are equipped with an HSAPN address, and all equipment and E.D equipment in the IP network are assigned IP addresses. Because the addresses of the HSAPN network and the IP network (taking the most widely used IP network as an example) are different, the HSAPN network also includes an address translation entity (ADT), and the mapping relationship between the IP address and the HSAPN address is stor...

Abstract

The embodiment of the invention discloses a fault detection method in layered ordered address packet network, comprising the following steps of: after receiving a fault detection conversation building request, and after receiving the fault detection conversation building request by a first node on a path to be detected, judging that the fist node is not the outlet node of the path to be detected according to the outlet node information carried in the fault detection conversation building request; building a first fault detection conversation with the next hop; and detecting the fault, after detecting the fault, sending fault notification information to the inlet node of the path to be detected or a terminal applied on an upper layer. The invention further provides a corresponding system thereof and equipment thereof, so that fault detection conversation is automatically built between each two node routers on the path to be detected so as to detect the fault of all the node routers on the patch to be detected.

Description

technical field [0001] The invention relates to a layered and ordered address grouping network, in particular to a fault detection method, system and equipment in the layered and ordered address grouping network. Background technique [0002] With the development of technology, the telecommunication network has successfully completed the transition from analog technology to digital technology, and digital technology has experienced the transition from circuit switching technology (such as TDM) to packet switching technology (such as IP, ATM and FR). In the evolution process, the transition from TDM (Time-Division Multiplexing, Time-Division Multiplexing) technology to packet switching technology is currently underway. The following three packet switching technologies (IP, ATM, and FR) will be introduced respectively. [0003] The transition from TDM technology to ATM (Asynchronous Transfer Mode, asynchronous transfer mode) packet technology has not been realized due to techn...
