Embodiment Construction

[0037] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0038] Such as figure 2 Shown, the structure of the layered data communication network of the present invention comprises:

[0039] 1) Select the PTN device at the core aggregation layer as the gateway network element, and use the out-of-band DCN method to carry it, and be responsible for the network management monitoring of itself and the expansion device on the transmission landing side;

[0040] 2) Select a network element in each access layer sub-ring (that is, access sub-ring) (or in some access sub-rings in densely distributed areas) as the gateway network element, and use the management network It is carried by the way of connecting DCN (in-band DCN) + out-...

Abstract

The invention discloses a networking method and device for a data communication network. The method comprises the steps that at least one sub-network node is selected as a sub-network gateway network element from an access sub-ring formed by hanging connection of two convergence nodes; an Ethernet port of a main control panel of the sub-network gateway network element is connected with an Ethernet port of a business veneer of the sub-network gateway network element; an Ethernet port of a business veneer of the convergence nodes is connected with an interchanger having access to a data communication network. Due to the adoption of the technical scheme, because the at least one sub-network node is selected as the sub-network gateway network element from the access sub-ring formed by the hanging connection of the two convergence nodes, the processing pressure of a gateway network element of a convergence layer is scattered to gateway network elements of different access sub-rings, the number of processed network elements does not surpass the limitation of equipment, and even through the number of network expansion elements increases continuously, the defects that the processing capability of the gateway network elements is weak can also be effectively overcome.

Description

technical field [0001] The present invention relates to packet transmission network technology in the field of communication, in particular, to a networking method and device for a data communication network. Background technique [0002] The network management of the packet transport network (Packet Transport Network, PTN) establishes communication with the network elements through the data communication network (Data Communication Network, DCN), and manages and maintains the network elements. According to the division of network management traffic, the PTN network management can adopt two deployment schemes: [0003] 1. Use out-of-band DCN network bearer, that is, use channels other than service channels to transmit network management information; [0004] 2. Adopt in-band DCN network bearer, that is, network management information is transmitted through the service channel of the device, including: [0005] (1) Intra-service port domain DCN: When PTN devices are connect...
