Embodiment Construction

[0041] Such as figure 1 As shown, the present invention includes two adjacent cross-node J0 byte processors. The cross node J0 byte processor includes a time slot / space cross-connect device (X), an overhead processor (C), a discovery agent (DA), a protocol controller (PC) and a management agent (MA), and the overhead processor ( C) Connected to the time slot / space cross-connect device, on the overhead byte read signal lines (R1, R2...RN) of the overhead processor (C) and each signal at the input of the time slot / space cross-connect device (X) The overhead read circuit (11, 1...1N) of the overhead processor (C) is connected to read the overhead byte of J0; the overhead byte write signal line (W1, W2...WN) of the overhead processor (C) is connected with Overhead writing circuits (21, 22...2N) on each signal at the output of the time slot / space cross-connect device (X) are connected for writing overhead bytes of the output channel. The Discovery Agent (DA) is connected to the P...

Abstract

The invention discloses a method and system for finding multiplex section neighbors by regenerator section trace byte, and the method comprises: 1) source node and destination node determine to start neighbor finding course by signaling; 2) the source node writes the information about neighbor finding identification, finding course type and multiplex section resource identification into regenerator section trace byte, and send the information through transfer plane link to the destination node, and the destination node extracts the resource information from the regenerator section trace byte and finds the resources; 3) the destination node sends finding success signaling to the source node, and the source node confirms to end the finding course. And the system comprises regenerator section trace byte processor, which comprises time gap / space cross-linking device, finding proxy, protocol controller, management proxy, overhead processor, overhead reading circuit and overhead writing circuit. And it can find multiplex sections by regenerator section trace byte (J0) and raise finding efficiency.

Description

technical field [0001] The invention relates to a method and system for discovering multiplex section neighbors, in particular to a method and system for realizing multiplex section neighbor discovery by using regenerating section trace bytes (J0). Background technique [0002] The current network is a network of information explosion. With the surge of data services, this development has brought great results but also brought heavy pressure to the actual transmission network. There are clear requirements for innovation and development. Actual requirements force the traditional network to evolve to the next generation network that supports multi-channel, high-capacity, configurable, and intelligent networks. In this evolution process, the point-to-point WDM system has taken the first step to solve the problem. After having the WDM (Wavelength Division Multiplex, wavelength division multiplexing) capability, the optical transport network has the capability of directly cross...
