Service supply setting device and method by connection check message packet

The present invention relates to an Ethernet connection fault management detection technology, which provides an automatic service provisioning setting in a network, and when performing the IEEE 802.1ag standard connectivity check message by the device and the method, The Organization-Specific TLV carried in the packet is placed in a predefined service provisioning setting information, so that when the remote device receives the connectivity check message packet of the corresponding end, the setting can be automatically completed, and the mechanism can be simplified in the network. It is inconvenient to set the service provisioning parameters for each device.

Traditional telecommunications networks have well-defined and fully functional Operation Administration and Management (OAM) functions, but traditional Ethernet networks cannot fully meet the service quality assurance required by telecom operators due to their simple technology. Develop the technical standard functions required for integrated network management such as supply, maintenance, and ordering of telecommunications. Therefore, in order to meet the needs of the electric operators, many international organizations have invested in the development of technical standards for the management and maintenance of Ethernet operations, such as IEEE 802.1ag for connectivity management and ITU for providing obstacles and performance monitoring. -T Y.1731, and IEEE 802.3ah for point-to-point inspection, etc., to achieve monitoring and obstacle detection purposes.

The IEEE 802.1ag standard provides connectivity barrier management and defines three management messages to assist administrators in detecting Ethernet networks, including Connectivity Check Messages (CCMs) and Link Trace Messages (Link Trace Messages). LTM) and backhaul messages (Loopback Message, LBM) and other three kinds of messages: (1) Connectivity check message: The periodic message sent by the maintenance endpoint can be used by the maintenance endpoint to detect whether the remote maintenance endpoint loses service connectivity. (2) Link tracking message: This is the message that is requested by the maintenance manager and transmitted from the maintenance endpoint to track a path point by point to the specified maintenance point so that the maintenance endpoint can obtain the important connection of the transmission path. Sexual information. (3) Return message: This is a message sent by a maintenance endpoint to identify the connectivity of a particular maintenance point when requested by the administrator. According to the definition in the IEEE 802.1ag standard, a Maintenance Point (MP) can be classified as a Maintenance End Point (MEP) or a Maintenance Intermediate Point (MIP). The maintenance endpoint exists at the edge of the maintenance zone, while the maintenance mediation point is inside the maintenance zone.
