Description
Technical field
The present invention relates to optical-fiber network, refer to a kind of management system that ASON and non intelligent optical-fiber network are managed concentratedly especially, and the method that realizes crossing over the optical transmission business of ASON and non intelligent optical-fiber network.
Background technology
ASON ASON (Automatic Switched Optical Network) a kind ofly can utilize independently control plane, implements the network of automatic connection management by various transmission nets.Compare with traditional Optical Transmission Network OTN, the characteristics of intelligent Optical Transmission Network OTN maximum have been introduced control plane exactly.Control plane is the outstanding feature that ASON is different from conventional optical network, its basic function comprises providing calls out control, call admission control, connection management, connection control, connection permission control, and supports UNI/NNI (UNI:User NetworkInterface User Network Interface; NNI:Network Network Interface Network-to-Network Interface) interface reaches and other network interconnection, support is got in touch with network management system, connection management in the multi-domain environment, Dynamic Bandwidth Allocation is supported multiple connected mode, calling control and the separation that is connected control etc.
Management function to control plane mainly comprises: connection management, Topology Management, tactical management, physical arrangements management, service management, fault warning management, safety management or the like.This also is place different between ASON network management system and the traditional network management.
After the ASON technology occurred and obtains implementing, the optical transport network of operator's operation maintenance logically just may and be deposited two class transmission networks: intelligent Optical Transmission Network OTN and traditional Optical Transmission Network OTN.
Presentation mode professional in the ASON is with different fully with non intelligent optical network service.ASON can provide permanent connection (Permanent Connection, PC), soft permanent connection (Soft PermanentConnection, SPC) with the exchange be connected (Switched Connection, SC).SC wherein and SPC will be by the participations of control plane, and route planning is that control plane is finished.In ASON, the SPC service creation procedure is: the user issues the requirement (comprising sourcesink, bandwidth requirement, the grade of service etc.) of business to be created from webmaster to control plane, and control plane planning route also utilizes signaling technology to set up professional the connection.Whole route planning is not realized by webmaster.And before the ASON technology occurred, the mode of creating business between the across a network is: webmaster integrated planning route, the webmaster single-point issued intersection.The planning that is to say whole route is that webmaster carries out.
In order to realize the effective management to these two kinds of networks, can use the separation Managed Solution: different networks uses the network management software separately, and coordination is between the two then undertaken by more high-rise webmastering software.It is comparatively ripe that the administrative skill of traditional optical transport network of no intelligent characteristic has developed, and the network management technology of ASON, the especially management of control plane management and three kinds of professional connection modes of ASON also are among the research exploration.

In addition, existing webmaster planning teleservice, or be pure IN service, or be pure traditional business.Can't plan the teleservice that merges two types of networks.If according to traditional approach planning, what obtain on ASON so will not be IN service but traditional SDH (Synchronousdigital hierarchy SDH (Synchronous Digital Hierarchy)) business, just can't make full use of the advance of ASON.
" ASON " literary composition that Sun Junbai writes (is seen the Huawei Technologies newspaper, 2003.07.20 the 184th phase), under the ASON that proposes and the situation of legacy network mixed networking, the scheme of the end-to-end fast circuit business configuration of subnet is striden in realization, require circuit to set up in the process, must on the access node of ASON, increase UNI (User Network Interface) agent functionality, and the control channel from the access node to the ASON is provided.Implement also more complicated.
In addition, in existing ASON and the non intelligent optical-fiber network, the user, just need create the professional of new different stage again and delete original business if want to change its grade of service in case establishment is professional.
From present development, will be the situation of intelligence and unintelligent device coexistence in a long time.Operator wishes to see the end-to-end management of business-level, rather than with intelligence and isolated the treating of non intelligent business; In addition, if can realize level and smooth simple and easy conversion mutually fast between the different brackets business, the flexibility and the specific aim of operator's service will be improved greatly.

Fig. 2 realizes ASON and non intelligent optical-fiber network control schematic diagram for adopting optical network management system of the present invention, as seen from the figure, the present invention adopts optical network management system to realize the optical-fiber network that intelligent characteristic is arranged and the optical-fiber network of no intelligent characteristic are monitored and managed.A typical end-to-end planning implementation process of striding the business of mixed subnet just is reduced to directly by network level webmaster module planning B-＞A-＞C-＞D-＞E-＞F.
Wherein B-＞A-＞C is an IN service, and type of service is selected by the user.
The information flow of whole constructive process is:
User request-＞man-machine interface-＞network level webmaster module (planning end-to-end route)-＞business configuration module (put non intelligent intersection in order and create demand) in the intelligent object (putting intelligent establishment demand in order), conventional optical network functional module-＞the Network Management Equipment interface-＞equipment.
Fig. 3 crosses over the flow chart of the end-to-end optical transmission business of ASON and non intelligent optical-fiber network for adopting optical network management system of the present invention to realize.Referring to Fig. 3, comprise the steps:
Step S1: set up service path.
One of method for building up of service path: network level webmaster module is used as traditional network element to the intelligent net element in the whole network, uses dijkstra's algorithm to obtain the route of a PC mode.
Two of the method for building up of service path: definition subnet node and subnet address in network; Each subnet routing table of configuration in network level webmaster module; Search corresponding subnet routing table according to source node, destination node and the subnet address thereof of teleservice, determine a service path.
Its concrete method for building up is referring to Fig. 4, for using the otherness between element management software EMS shielding smart machine and the unintelligent device, the schematic diagram that on the EMS basis, uses centralized network management software NMS to carry out comprehensive service management and conversion thereof in the integration program between the intelligent sluggish network of Sun Jun cypress proposition.
As shown in Figure 4, the subnet of EMS (comprising EMS1, EMS2, EMS3) management belongs to same manufacturer, and the management system between the different sub-network can intercom mutually.The subnet at two ends is made up of traditional optical network device, and middle subnet is made up of intelligent optical network equipment, and sub-net boundary is defined on the node.Suppose: the subnet address is defined as X1, X3, X2, and the subnet address is the polymerization address of all nodes in the subnet, is polymerized to X3 as the address of F, C, D, G node port.
Equally, conventional optical network has also defined the subnet address, and need embody on webmaster.
The routing table that subnet X1 disposes on webmaster is:
Purpose subnet X3, X2 go out gateway node F or C.
The routing table that subnet X3 disposes on webmaster or node is:
Purpose subnet X1 goes out gateway node F or C;
Purpose subnet X2 goes out gateway node G or D.
The process that the user sets up an end to end circuit business from A to Z is as follows:
In parameters such as EMS1 input source/destination node port address, bandwidth, protection types, EMS1 finds one to go out gateway node C according to the routing table of destination node Z inquiry subnet X1 configuration, and EMS1 sets up the inner track A-B-C from A to C in this subnet;
EMS1 notifies EMS3, and EMS3 finds one to go out gateway node D according to the routing table of destination node Z inquiry subnet X3 configuration, and ASON calculates the path C-D of subnet X3 inside from C to D by distributed method, and connects;
EMS3 notifies EMS2, because destination node Z is in subnet X2, therefore, EMS2 directly sets up the inner track D-E-Z of subnet X2 from D to Z.
So far, the end-to-end path A-B-C-D-E-Z that crosses over mixed subnetworks all sets up.Same method can also be set up one and protect the path end to end, loses efficacy simultaneously for fear of operating path and protection path, and two paths should select difference to go out gateway node.
As can be seen, when the end to end circuit that adopts this method realization to stride mixed subnetworks connects, only need defined node and subnet address on webmaster, and do not need traditional optical network device is made any change.This shows that the present invention also can adopt this kind method to set up the service path of crossing over ASON and non intelligent optical-fiber network, only need configure each subnet routing table in network level webmaster module of the present invention and just can realize.
Step S2: the network level webmaster is according to the service path of determining, whether each the node network element on the point-to-point analysis path is intelligent net element, and judge whether this service path passes through two or more intelligent net elements continuously, if have, then the route segment between the continuous intelligent net element is designated the intelligence section, and the prompting user selects whether to create IN service on the intelligence section that is identified; Execution in step S3; If the service path of determining does not promptly have the intelligence section not continuously through plural intelligent net element in this service path, then go to step S5.
Step S3: whether on the intelligence section, create IN service by autonomous selection of user, if the user selects to create IN service, execution in step S4 then, otherwise, go to step S5.
Step S4: network level webmaster module issues teleservice and gives the intelligent network management module, creates IN service on described intelligence section; Issuing teleservice simultaneously creates non intelligent business for the traditional network management module on the residue highway section.
Step S5: network level webmaster module issues teleservice and gives the traditional network management module, creates non intelligent business on the whole piece service path.
If the user is chosen in the soft permanent connection IN service that the intelligence section is created 1:1 or 1+1 type, advise that then network level webmaster module is connected (SNCP) etc. to multiplex section and carries out verification with subnet, whether the multiplex section resource that meets the demands is arranged or sufficient link circuit resource is arranged for creating the SNCP business with checking.The method of verification is exactly: the multiplex section verification---whether created multiplex section protection on the verification intelligence section business route; Subnet connects verification---and whether can search out 1+1 on the verification intelligence section business route and connect to come with Dijkstra.
The user is provided with different intelligent attributes respectively can for each intelligence section, for example:
The restorability of IN service: for IN service, under the situation that existing link breaks down, can plan route again and switch on the new route, after original route is eliminated fault and is recovered to be communicated with, can switch again can former route attribute;
But the recovery time of IN service: occur to the time span of eliminating fault and recovering to be communicated with from fault;
The locking of IN service: after being set to locking, even former route recovery, the also attribute that the former route of business switching meeting is not got on.
After the intelligent network management module receives the request of the establishment IN service that network level webmaster module sends, issue the IN service request to create by intelligent object to control plane, the control plane IN service type of creating according to request after the order that accepts request is created IN service.Intelligent object among the present invention is responsible for control plane management and IN service and is realized as a standalone module in the optical network management system of the present invention.Other and traditional network management identical functions (for example configuration, fault, performance, alarm etc.) all can be responsible for by network level webmaster module of the present invention, to realize information synchronization between intelligent object and other conventional optical network functional module, so that update the equipment information such as configuration status, alarm performance at any time.
When if control plane is judged the current business path and can not be created IN service resources supplIes such as (for example do not satisfy) time slot collisions, then create permanent connection service automatically, guarantee the establishment success of teleservice.
In the said method, if analyze the teleservice path set up the network element of process all be intelligent net element, then network level webmaster module also can be controlled the intelligent network management module automatically and create IN service on the whole piece service path, need not selected by the user.
In the said method, if analyze the teleservice path set up the network element of process all be non-intelligent net element, then network level webmaster module is controlled the non intelligent business of traditional network management module creation automatically.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
