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
The present invention relates to the communication technology, be specifically related in the ASON, especially the soft permanent SPC in the ASON connects method for building up.
Background technology
Automatically exchange light networking ASON utilizes control plane to finish automatic exchange and the optical transfer network that is connected control, and it is to be the physical transfer medium with optical fiber, the optical transfer network with intelligence that optical transmission systems such as SDH and OTN constitute.The ASON server is a network intelligence, comprises that signaling, route and automatic discovery feature are to realize the intelligent network controlled function.The ASON network configuration can be divided into three planes according to function: control plane, transmit plane and management plane, also comprise the data communication network that is used to control with supervisory communications in addition.Wherein control plane is the core of ASON, and it is made of one group of control assembly that specific functions such as route and signaling are provided, and is supported by a signaling network.The major function of control plane comprises: set up, remove and safeguard the end-to-end ability that is connected by the signaling support, select suitable route by route for connecting; Automatically find syntople and link information, the issue Link State; During network failure, execute protection and restore funcitons.
According to the promoter who connect to set up with set up the different of mode, have following three kinds of connection: PC, SPC and SC in the ASON network.By network management system one by one the connection of the point-to-point set up of the network element on the configuration path be called as permanent connection Permanent Connection, be called for short PC, it does not use signaling; Initiated by client, the connection of setting up by the mutual signaling message between Control Node is called as switch type and connects Switched Connection, is called for short SC; And initiate by network management system, use PC at network edge, the connection of using signaling procedure to set up in network internal is called as soft permanent connections SoftPermanent Connection, abbreviation SPC.
Traditional SPC sets up, and as shown in Figure 1, thick line is that SPC connects 4 among the figure, and dotted line is the control information in the establishment step, and the process of foundation comprises following concrete steps:
110) operating personnel send SPC by network management system 1 and set up request, and the request that network management system 1 will have been carried various parameters sends to control plane 2;
120) after control plane 2 is received request, carry out route and calculate, initiate signaling procedure according to the path that calculates then, the order transmission is carried out in pointwise 21 in control plane;
130) control plane pointwise 21 sends to transmission plane 3 with the intersection information of each point, transmits plane 3 and carries out cross-over configuration according to configuration information in corresponding node 31;
140) signaling procedure executes, and transmits the configuration on plane 3 and also finishes simultaneously, and control plane 2 feeds back to network management system 1 with link information, checks for operating personnel.
From said process as can be seen, SPC also disposes transmitting the plane, after receiving the feedback of control plane when carrying out route calculating and signaling transmission, operating personnel can see the information of SPC from network management system, include, but are not limited to route, time slot or wavelength.If through after checking analysis, operating personnel think that control plane is unreasonable for this SPC connects the route and the time slot that distribute, need adjust, the plane is set up because SPC is connected transmission, operating personnel must delete this connection from transmitting the plane by first transmitting order to lower levels, and then carry out new connection and set up the purpose that reaches oneself.In the process of adjusting, need the operation on transmission plane repeatedly, not only efficient is low, and has increased the risk that breaks down.
Summary of the invention
The technical issues that need to address of the present invention are how soft permanent connection method for building up in a kind of ASON is provided, and can submit necessary information in advance by transmitting the foundation operation on plane, the risk that reduction is broken down after operating personnel's affirmation again.
Above-mentioned technical problem of the present invention solves like this, and soft permanent connection method for building up in a kind of ASON is provided, and it is characterized in that, adopts the preview connected mode, may further comprise the steps:
1.1) the ASON network management system sends soft permanent connection by network management protocol to this ASON control plane and set up request;
1.2) described control plane carries out route according to the subsidiary parameter of described request and calculates, draws access path and initiate signaling procedure between Control Node by this path: the order transmission is carried out in pointwise, preserves the routing iinformation of this access path simultaneously;
1.3) described control plane utilizes network management protocol to feed back to described network management system described routing iinformation and check and preview for operating personnel;
1.4) operating personnel transmit actual foundation on plane according to described checking with this access path of object command of preview in the dismounting of described control plane or at this ASON.
According to method for building up provided by the invention, described step 1.4) demolishing process in may further comprise the steps:
