Description
Technical field
The present invention relates to the resource division in the ASON network, a kind of specifically based on the method that realizes resource division in the ASON network of SDH.
Background technology
Because ASON network (Automatically Switched Optical Network, ASON) can provide service dispatching ability more flexibly, Feng Fu type of service relatively, shorten and set up the professional time, alleviate the workload of service maintenance, therefore it enjoys industry to pay close attention to, and uses also more and more.
According to G.8080 (G.ason) suggestion of ITU-T, the ASON network is divided into the independently aspect of three on plane, control plane, management plane that transmits.Wherein, transmitting the plane provides the two-way or unidirectional information from an end points to another end points to transmit, finish optical signal transmission, multiplexing, configuration protection is switched and function such as interconnection.Control plane provides foundation, removes and safeguards the end-to-end ability that is connected by signaling, selects suitable route by routing for connecting; When network breaks down, control plane execute protection and restore funcitons; Control plane can also be found syntople and link information automatically, and the issue link-state information is set up, removed and recover to support to connect.Management plane is implemented transmitting the management function of plane, control plane and system, guarantee the collaborative work between all planes, management plane provides the M.3010 management function of regulation, comprises performance management, fault management, configuration management, accounting management and safety management.
Three kinds of professional connection types of ASON network support promptly forever connect PC, exchange connection SC and the soft permanent SPC of connection.The permanent PC of connection is initiated by management plane, along the specified path mode that connects of network element one by one, and remains to this connection always and is deleted by management plane.It is that networking client passes through the initiation of UNI signaling interface that exchange connects SC, use the route and the signaling capability of ASON network to set up automatically, networking client can be regarded the user of network as, automatically initiate service request, service request is issued control plane by uni interface, and the interconnection configuration was set to transmit the plane after control plane calculated automatically.Soft permanent connection SPC is initiated by management plane, uses the route and being connected that signaling capability is set up automatically of ASON network.The permanent PC of connection is the connection of being initiated by management plane with the soft permanent SPC of being connected, distinguishes to be that the process that optical-fiber network inside connects utilizes webmaster order or real-time signaling.Soft permanent connection SPC is connected the SC business with exchange and is set up by control plane and safeguard.Concrete condition is as shown in the table:
| The permanent PC that connects | Exchange connects SC | Soft permanent connection SPC | |
| The professional initiation | Management plane | Networking client | Management plane |
| Professional foundation | Management plane | Control plane | Control plane |
| Service maintenance | Management plane | Control plane | Control plane |
At present in the ASON network based on SDH, the local resource of managing in the control plane is that time slot with data link is a unit usually, and the high-order time slot type of support comprises: VC4, VC4-4C, VC4-8C, VC4-16C, VC4-64C and VC4-256C.
In traditional SDH network, to have only management plane and transmit the plane, professional initiation, foundation, maintenance are all finished by management plane, and above-mentioned all local resources all return management plane to use, and therefore do not need to carry out resource division.And in the ASON network based on SDH, increased and to have finished the professional foundation and the control plane of maintenance, if all being soft permanent connection SPC/ exchange, the business in the network connects SC business (promptly all business are all set up by control plane and safeguarded), its all local resources all return control plane to use, and also can not have problems.But in practical engineering application, partial service is to be initiated by management plane, foundation and maintenance, and partial service is just initiated by management plane or networking client, set up and safeguard by control plane, the business that business that management plane is set up and control plane are set up exists in real network is used simultaneously, the business that management plane is set up the local resource control plane of process do not know, and the business that control plane is set up the local resource management plane of process do not know, therefore some local resource need be managed by management plane and use, some local resource needs the management of Be Controlled plane and uses, this just causes and following phenomenon may occur: the local resource of the business that control plane is set up is taken by management plane, and the local resource Be Controlled plane of the business that management plane is set up takies.In addition, (promptly set up the link traditional protection attribute business that is provided with) in the business of the traditional protection that control plane is set up, control plane need be reserved a part of local resource and be used for professional traditional protection.
In ASON network based on SDH, be not repeated to use in order to guarantee the PC local resource professional and the SPC/SC business that control plane is built that management plane is built, need divide with clear and definite its purposes it.But existing ASON network based on SDH is not considered the professional and professional situation about coexisting of SPC/SC of PC, and this has just limited the ASON network in actual application in engineering.

With Fig. 5 is example, management plane is directly set up a PC business to the resource management module request by resource 1, the external command that send on resource management module receiving management plane, convert thereof into the driving incident of changing between state---set up the PC business, resource management module obtains the current resource status of local resource, find that resource 1 is in the control plane occupied state, resource status according to Fig. 1 is migrated figure, resource management module sends error message to management plane, and the notice management plane can not be set up the PC business by resource 1.
With Fig. 6 is example, the SPC business that management plane is set up by resource 1 by service management module request deletion, resource management module receives the external command that the service management module is sent, convert thereof into the driving incident of changing between state---discharge the SPC business, resource management module obtains the current resource status of local resource, find that resource 1 is in the control plane occupied state, resource status according to Fig. 1 is migrated figure, resource management module discharges the SPC business, is idle condition with the current resource status modification of resource 1.
As mentioned above, below resource status being migrated figure is described as follows one by one:
Idle condition: after resource was found to finish automatically, the initializing resource on the link was an idle condition, represents that this resource can be taken by any business;
Management plane occupied state: after management plane is set up the PC business, corresponding resource status is defined as the management plane occupied state, represent that the PC business that this resource set up by management plane is shared, this resource is invisible to control plane, can not be used to set up the SPC/SC business;
Control plane occupied state: after control plane is set up the SPC/SC business, corresponding resource status is defined as the control plane occupied state, the SPC/SC business that expression resource Be Controlled plane is set up is shared, and this resource is invisible to management plane, can not be used to set up the PC business;
Reservation state: (link traditional protection attribute/cancellation link traditional protection attribute is set) in the business of the traditional protection that control plane is built, the resource that is used to protect is divided out, is defined as reservation state, represents that this resource reservation uses to protection is professional.
Set up the SPC/SC business: after the driving incident of changing between this state was carried out, the resource conversion of idle condition became the control plane seizure condition.
Discharge the SPC/SC business; After the driving incident of changing between this state was carried out, the resource conversion of control plane seizure condition became idle condition.
Set up the PC business; After the driving incident of changing between this state was carried out, the resource conversion of idle condition became the management plane seizure condition.
Discharge the PC business; After the driving incident of changing between this state was carried out, the resource conversion of management plane seizure condition became idle condition.
Link traditional protection attribute is set; After the driving incident of changing between this state was carried out, the resource conversion of idle condition became reservation state.
Cancellation link traditional protection attribute; After the driving incident of changing between this state was carried out, the resource conversion of reservation state became idle condition.
It is that what order the resource status managed as required and every kind of resource status can accept and self-defining that the definition resource status is migrated figure.When not having new resource status or order, be changeless.At present, the driving incident that can receive of the resource under the idle condition for set up the SPC/SC business, to set up PC professional and the traditional protection attribute is set; Resource under the control plane seizure condition can only receive the driving incident that discharges the SPC/SC business; Resource under the management plane seizure condition can only receive the driving incident that discharges the PC business; Resource under the reservation state can only receive the driving incident of cancellation traditional protection attribute.
The local resource administration module of control plane is responsible for finishing the management of resource: control plane is set up the resource of professional process, and the local resource administration module checks whether this resource is taken by other business, if just do not carry out mark (resource division); When management plane is set up business, need be the local resource module of the resource notification control plane of this professional process, whether these resources of local resource module check are shared by other business, and check result returned management plane, if do not taken, carry out mark (resource division) by other business.
