Method and system for detecting end-to-end connectivity of telecommunication grade ether private wire

Abstract

The invention discloses an telecommunications level ether private wire end-to-end connectivity detecting method and system terminal, including: detecting the connectivity of subscriber circuits in operator network by the operational maintenance management OAM of telecommunications level Ethernet, and operators, through telecommunications level Ethernet apparatus, actively initiating internet packet ping test message to subscriber terminals of local network side and remote network side through a two-layer circuit; judging whether the response message returned form subscriber terminals are received, if so, judging that the circuit from the operator to the subscriber terminals is communicated. By the invention, the operator can perform full distance telecommunications level ether private wire end-to-end connectivity detection without participation of subscribers, thereby providing differential service for subscribers and advancing perception of subscribers.

Description

technical field [0001] The invention relates to a two-layer private line realized by carrier-grade Ethernet technology, in particular to a method and system for detecting end-to-end connectivity of a carrier-class Ethernet private line circuit. Background technique [0002] Traditionally, when Layer 2 leased lines are used for interconnection, user routing is transparent to operators, so the security and autonomy of user networks are better than Layer 3 leased lines, and are favored by high-end users who have high security requirements. [0003] In this case, generally, there are two ways to judge the connectivity of the carrier-grade Ethernet leased line: the first is that the operator detects the connectivity within the operator's network segment through carrier-grade Ethernet OAM (Operation, Administration, & Management). The second is that the user realizes the end-to-end Layer 3 connectivity detection of the user circuit by pinging the IP (Internet Protocol, Internet Pr...

Problems solved by technology

[0004] However, there are certain problems in the existing two methods: the first method does not detect the circuit connection between the edge of the operator's network segment and the user's network terminal; the second method requires the user to actively initiate a ping (Internet packet Explorer) test, which may affect the perception of some users

Therefore, the above-mentioned two-layer circuit detection method cannot meet the needs of some specific users, that is, the users themselves are unwilling or unable to do the ping circuit connectivity test, but fully trust the network security of the operator, and hope that the operator can replace the user to complete the test.
