Equipment in-band management achieving method based on media access control (MAC) frame

Abstract

The invention relates to an equipment in-band management achieving method based on a media access control (MAC) frame. A center terminal achieves complete isolation of equipment management and business, and nodal point terminals achieve analysis and execution of Ethernet service and operations, administration and maintenance (OAM). A downlink is defined from a center to nodal points and an uplink is defined from the nodal points to the center. The direction of the downlink is that Ethernet service data and OAM data are exchanged through a switchboard, and the switchboard is used for being connected to a center access point (AP) of a transport network. The direction of the uplink is that the Ethernet service data and the OAM data isolate business data flow and OAM data flow at different ports through the switchboard and in a virtual local area network (VLAN) exchange mode, and nodal point equipment topology automatic discovery, interface protection switching strategy, equipment outage alarm achieving and equipment business management achieving are specifically included. The equipment in-band management achieving method based on the MAC frame can achieve intelligently discovering the equipment topological structure, including point-to-point topology, single-point topology and the management of an equipment on-line state, an off-line state and an off-position state after a crossing packet transport network.

Description

technical field [0001] The invention belongs to the field of PTN (Packet Transport Network) data communication, and relates to a method for implementing in-band management of equipment based on MAC frames, specifically using Ethernet MAC frames to penetrate PTN, thereby realizing equipment management, and using store and forward to realize Ethernet data transmission . Background technique [0002] At present, the metropolitan area network of operators is mainly based on SDH (Synchronous Transmission System). Network construction, the existing SDH network is already difficult to carry user data services, so the operator is laying a new PTN network to meet the growing demand for bandwidth. When an operator provides private line access for VIP customers based on the PTN network, there are two types of user equipment solutions: [0003] The first is to use a fiber optic transceiver in the user computer room. User data is connected to the transceiver through an Ethernet cable. ...
