Problems solved by technology

Using this method, there are the following disadvantages: the route between the ASON domain and the traditional domain needs to be manually specified, rather than automatically calculated by the routing algorithm, which is not easy to optimize; for a connection passing through the traditional device domain, it actually corresponds to the route on the control plane. Multiple independent connections, the signaling of these connections is not connected to each other, which brings troubles to the protection / restoration, maintenance and management of connections

Embodiment

[0033] figure 2 The network structure of the hybrid network including the ASON equipment and the traditional optical network equipment in this embodiment is shown.

[0034] Such as image 3 As shown, in this embodiment, the method flow of the intercommunication between the automatic switching optical network and the traditional optical network is:

[0035] The first step is to abstract the transmission resources of the traditional optical network equipment domain in the network, and abstract it as a virtual node; the abstract content includes: the port, link, and internal cross-connection relationship of the virtual node;

[0036] The concrete abstract method is:

[0037] 1. Hide the resources inside the traditional optical network equipment domain network, use the topologically connected ports of the traditional optical network equipment domain with the ASON domain as the virtual node ports, and identify the ports (different ports should have different Identification), record t...

Abstract

The invention discloses an intercommunicating method between an automatically switched optical network and a traditional optical network, which comprises the following steps: a device domain of the traditional optical network is abstracted as a virtual node, and sending resources of the virtual node, that are corresponding to the device domain of the traditional optical network, are obtained; a control node is configured in a control plane and taken as a mapping of the virtual node in the control plane, and a network administration system is used for configuring the sending resources of the virtual node for the control node and deriving links for penetrating the virtual node according to the sending resources; and when a connection that is used for penetrating the device domain of the traditional optical network is built, the control plane can be used for realizing the integrated control of the whole network including the traditional optical network and the automatically switched optical network in the way of the automatically switched optical network. The intercommunicating method of the invention completely utilizes the control capacity of the ASON, lowers the complexity of network operation and management, and improves the intelligent property of the whole network.

Description

Technical field [0001] The present invention relates to optical communication technology, in particular to a method for intercommunication between an automatic switching optical network and a traditional optical network. Background technique [0002] ASON (Automatically Switched Optical Network) is an optical transmission network that uses a control plane to complete automatic switching and connection control. It uses optical fiber as the physical transmission medium, SDH (Synchronous Digital Hierarchy, Synchronous Digital Hierarchy) and OTN (Optical Transport) Network, optical transmission network) and other optical transmission systems constitute an intelligent optical transmission network. The core of the automatic switching optical network ASON is network intelligence, including signaling, routing and automatic discovery functions to realize intelligent network control functions. The automatic switching optical network structure can be divided into three planes: transport pla...
