Embodiment Construction

[0059] Various preferred embodiments of the present invention will be described in detail below with reference to FIGS. 1-5 .

[0060] The device and method for upgrading to automatic switching optical network equipment of the present invention are based on the existing transmission network equipment that has been widely operated, adding control plane functional units, so that the existing transmission equipment can realize the function of intelligent optical network equipment, thereby realizing the present There is a smooth transition from network to intelligent optical network.

[0061] The equipment upgrade method of the present invention needs to consider the following requirements: In the transmission equipment with cross-connect capability, the original cross-connect configuration is updated from static to dynamic, that is, the so-called dynamic switching capability is formed.

[0062] For this reason, the hardware feature of the new function structure of the present inv...

Abstract

This invention discloses one device and method to update automatic exchange network devices, wherein, the device comprises one control plane function unit to send support of three layers of intelligent network structure from traditional transmission network management plane; one device fix network element agent, one control function unit inner interface, one outer interface, at least one element agent inner interface, at least one agent outer interface, network element control unit and management plane function unit interface.

Description

technical field [0001] The present invention relates to an upgrading device and method of communication equipment, in particular to an upgrading device and method of optical transmission network communication equipment. Background technique [0002] With the rapid growth of new data services, higher requirements are placed on the transmission network. With the development and application of WDM technology, the bandwidth of the transmission link will no longer be the main contradiction in the development of optical transport network in the short term, and the flexibility, stability and intelligence of the network will become the focus of attention. So the industry has turned its attention to a new generation of intelligent optical network - Automatic Switching Optical Network (ASON). ASON was developed to meet the above requirements. Its concept system is to add a "control plane (ITU-T G.8080)" on the basis of the existing transmission network model, so that the optical netw...
