Embodiment Construction

[0033] The realization method of the optical label of the present invention mainly makes multiple wavelengths in the optical network use the frequency of the label signal in time-division and in turn to transmit the relevant information of the wavelength. Such as figure 1 shown, including:

[0034] Step 101, divide the optical network into domains according to ROADM nodes, and assign one or more tag signal frequencies to each domain.

[0035] Step 102 , in each domain, transfer the assigned tag signal frequency between ROADM nodes and / or among wavelengths within the ROADM node according to a preset time-sharing rule.

[0036] Step 103, the wavelength sends the tag signal using the transmitted tag signal frequency.

[0037] Combine below figure 2 with image 3 The scheme of the present invention is described.

[0038] Such as figure 2 As shown, the optical network is divided into domains according to ROADM nodes, and the division method can be based on the IP addresses ...

Abstract

The invention discloses a realization method of an optical label, and the realization method comprises the following steps: carrying out the domain division of an optical network according to the nodes of an ROADM (reconfigurable optical add-drop multiplexer) and distributing one or multiple label signal frequencies for each domain; transferring the distributed label signal frequencies among the nodes of the ROADM and / or among the wavelengths in the nodes of the ROADM according to the preset time division rule in each domain; and transmitting label signals according to the label signal frequencies used by the wavelengths to transfer. The invention also discloses a realization system of the optical label. The scheme in the invention realizes the purpose of transmitting the label signals which have the multiple numbers of the wavelengths, reduces the requirements of the system on the label frequencies and is beneficial to the extraction of the label signals through fewer label signal frequencies.

Description

technical field [0001] The invention relates to an optical communication network, in particular to a method and system for realizing an optical label. Background technique [0002] With the development of wavelength division multiplexing (WDM, Wavelength Division Multiplex), the current optical communication network can simultaneously transmit multiple optical signals or optical channels of different wavelengths in the same optical fiber, and based on reconfigurable optical add-drop multiplexing The ROADM (Reconfigurable Optical Add-Drop Multiplexer) technology facilitates the on-demand configuration of each wavelength in optical communication, so that the wavelength in the optical network does not always go through the same path between two sites, or a certain wavelength does not always go through the same path. Always assigned to a constant two sites. [0003] In order to carry out network topology identification and optical channel detection, a low-frequency label signal...
