Embodiment Construction

[0039] The SPC connection establishment method of the present invention, concrete process is as Fig. 2, and among the figure thick line is SPC connection 4, and dotted line is the control information in the establishment step, and corresponding establishment step comprises:

[0040] 200) (the operator 11 sends a request to establish the SPC connection 4 through the network management system 1,) the network management system 1 sends the request carrying various parameters to the control plane 2.

[0041] 210) After the control plane 2 receives the request, it performs route calculation, and then initiates a signaling process according to the calculated path, transmits commands point by point 21 in the control plane, and saves the connected routing information (including time slots) in the control plane. or wavelength information).

[0042] 220) The control plane 2 feeds back the routing information (including information such as time slot or wavelength) of the SPC connection 4 ...

Abstract

The invention relates to a method for building soft permanent connection in intelligent light network. Wherein, it comprises that network manage system (1) sends soft permanent connection (4) request; the control plane (2) based on request and parameter calculates out route, obtains connection path, initializes the signal process in control nodes (21), and stores the route information; the control plane (2) feedbacks the route information via network manage protocol to the network manage system (1) to be browsed by operator; based on the browsed result, instructing the detachment of said connection path at the control plane (2) or build at the intelligent light network transmit plane (3). The invention browses the connection method to replace direct build, with which the connected route information can be seed before building SPC at transmit plane.

Description

technical field [0001] The invention relates to communication technology, in particular to a soft permanent SPC connection establishment method in an intelligent optical network, especially in an automatic switching optical network. Background technique [0002] Automatic switching optical network ASON is an optical transport network that uses the control plane to complete automatic switching and connection control. It uses optical fiber as the physical transmission medium, and is an intelligent optical transport network composed of optical transmission systems such as SDH and OTN. The core of ASON network is network intelligence, including signaling, routing and automatic discovery functions to realize intelligent network control functions. The ASON network structure can be divided into three planes according to functions: control plane, transmission plane and management plane, and also includes a data communication network for control and management communication. Among t...
