10. command execution control assembly: according to the control content of command sequence, carry out relevant command operation, finish relevant configuration task to equipment.
End-to-end path selects assembly and business object schematic diagram illustrating all to call the resource query assembly, carries out the inquiry of resource information from Object Management group platform or third-party resource management system.
Four, about service fulfillment resource model based on general object modeling and data management platform:
Resource model is abstract to network, business, client in the real world and of concerning between them, the process of service fulfillment is exactly the process that resource status changes in essence, just the Internet resources of physical/logical is changed into a process of service resources.
Service fulfillment resource model of the present invention adopts the method for object to describe, and is realized that by the Object Management group platform service of resource data is provided, and the present invention also can support all to meet the resource management system of OSSJ API standard.
Model-driven is the soul of system, the present invention has adopted the method for general object modeling, node (can be equipment, port, terminal) in the description network and the annexation (can be relaying, circuit, path etc.) between the node, and the annexation between network and the network (virtual connections), adopt unified data description and tissue, adopt the support of multilayered model realization from the universal model to the Professional Model, for the service application exploitation provides the basis.The foundation of resource model is divided into three levels (as Fig. 2): lowermost layer be object layer, it is abstract on this level all Internet resources examples to be carried out general characterization according to the thought of OO fully, adopt the form of unified standard to describe, form the general object (in this level, object all is an independent entity) of tissue in order; The intermediate layer is the object relationship layer, and the application characteristic according to object on this level defines and describes relation between objects (such as inclusion relation, adduction relationship and other incidence relations etc.), forms the resource object model of specific area; The superiors are Business Logics, define specific operation or the method that object is had in specific area on this level, and carry out combination with relevant applied logic, thereby form a general resource model of specific area at last.
In addition, the present invention also supports the resource model of the resource model of service fulfillment and traffic supervision is unified, and for behind service fulfillment, immediately the business realizing dependent surveillance of being opened is provided the basis of resource data.Pass through model-driven, realized separating of data, model and application, complicated service is opened problem divides and rule, the resource data management platform that the service fulfillment of multi-vendor for realizing, multi-level, multi-service, cross-region provides a flexible expansion and realized fast, this has also effectively supported the realization based on the component technology of data flow driven.
Five, about generic configuration engine based on template and parameter replacement:
Fig. 3 has described the structure of the generic configuration engine in the CAP platform, under the driving of data flow, by service parameter template audit component, at first the different business required parameter that info is represented carries out validity and accuracy audit, info is the data structure body that adopts XML to describe, different service fulfillment request data structures are different, increase a kind of new business is opened configuration, need increase a kind of masterplate of describing the new business data structure in the predefine template, this assembly just can be handled new business.The parameter transition components receives through the relevant parameter in the atom business object of audit, obtains corresponding parameters conversion mapping and computing configuration, and service parameter is converted to the parameter that the configuration order template needs.The command analysis assembly, be associated with relevant manufacturer, unit type, operating system version, continuous item in command parameter and the template is replaced, formed and finish an atom business operation, device-dependent configuration order sequence, and command sequence is put in the command queue.By the job scheduling assembly, command sequence is sent to command execution and affairs control assembly, finish configuration to particular device.
The characteristics of generic configuration engine are:
1. realized separating of business description and command description feature: in the process that order generates, with template audit, parameter replace, the process of command analysis carries out processed by data flow driven.Template is replaced can realize unified business description, Info atom business object is mapped to the masterplate of the device parameter replacement of different vendor, different model; Parameter is replaced the command analysis parameters needed that the service parameter in the order can be mapped in the template, to realize the independence of professional and device command; The process of command analysis is just replaced the parameter of order the variable in the template, to generate command sequence.
2. the generative process of Ming Ling execution and order is independent fully, the command sequence in the formation is carried out the scheduling of FIFO by the job scheduling assembly
3. the extensibility of system is good, can dispose a plurality of different command execution assemblies, and a command execution assembly can dispose different command interaction modes such as telnet, ssh.
By above technological means, the present invention can accomplish the service fulfillment to any kind, only need customization relevant template and parameter maps table, just can realize being described to the mapping of device command sequence from business, and and equipment between command sequence alternately.
Six, about resource-based cost model routing algorithm:
1. the foundation of cost model
In essence, the process of service fulfillment is exactly the path of service point equipment in the network or service point equipment composition to be carried out the configuration of automation.In the human configuration process, service point equipment or path all are by manually selecting to specify according to selective rule, for automatic open system, solve the selection problem in service point equipment or path with regard to needs.
Resource-based cost model and be the method that this programme solves end-to-end Path selection in the professional opening process automatically based on the routing algorithm of cost, the cost here is not the value of the amount of money weighing apparatus in the economics, but the notion of an expansion, cost is that one group of factor that influences Path selection is (as bandwidth, shortest path, the factor of cost and user's particular provisions) overall target that is combined to form according to weight, cost need be followed the variation of its influencing factor and be changed, cost is directly related with the resource object (for example, equipment) of seeking footpath node representative.
By combining with resource model, make cost become the attribute that each resource object all has, the relation between resource model and the cost model is as follows:
Cost model is to form in the basic enterprising line translation of the combination of network model and resource model.No matter be from using, still from technical standpoint, network model is the skeleton of whole communication network, each deviceelement in the network is treated as a point, description be the relation between all network element points in the network; Resource then is that each equipment itself is described as the network element object, has represented the feature of device object.
Network model and resource model combination, conversion is the cost model of formation afterwards, not only possesses the framework of network model, has possessed the content of resource model simultaneously.The binding site that forms cost model is a network element, map function is not only calculated and has been produced cost factor, and the structure to network model is adjusted, cost model has followed the structure of network model, but its edge is given prominence to, the edge object is strengthened, non-edge object is hidden shielding, only inner as seen in present networks, make network object concern that being reduced to only is the connection between the fringe node between the network with layer; On each layer of structure of cost model, what present all is the simple graph that Points And lines forms, on the line between cost is embodied in a little.
Solid black initial point among Fig. 4 is exactly the edge network element, and 3 subnet objects of 3 big same levels of ellipse representation, the line between the subnet represent that the edge connects the cost of this access path of numeral on the line; The single node line on both sides has represented to have exceeded the boundary node and the line of range of management.
It between the neighbouring two-layer subnet object of cost model the C/S relation, connection between per two edge end points in the C network of upper strata all will have in the S of the lower floor network object of at least one correspondence and the connection (as above Fig. 5) between object, makes that the service clientage between the C/S can be carried out smoothly;
Set up cost model, just set up theoretical foundation for Path selection.
2. routing algorithm
Carry out Path selection, at first be exactly to produce a Path selection sterogram that meets cost model, the Path selection reference diagram is to observe cost model, and is concrete in conjunction with actual network model figure and actual resource model entity, and changes the result with the cost factor computing.The computing of cost factor is according to service needed, determines to influence the key element of Path selection, and specifies the weight and the operational formula of each elements affect, Path selection is influenced key element compile and become an algorithm factor.
With layer network cost figure is basically on the basis of network model figure, distinguishes edge and inside, sets up the edge connection respectively and is connected with inner, and the relevant cost factor is to each connection.
The generation of levels network cost figure is that of making progress of the cost figure of lower floor converges and simplifies: hide last being connected in internal node and the network, only fringe node and edge are connected in the upper layer network object and expose, and the inside that rises to the upper strata object connects or the edge connection;
Having formed choosing footpath figure according to cost model, how therefrom to have selected a path that meets business demand, then is the work of routing algorithm.
Mention selection algorithm, two kinds of choice directions are technically arranged, one is the degree of depth, and one is range.
The routing algorithm of CAP is based upon on the cost model basis, is the algorithm that combines the degree of depth and range dual mode.Path selection be exactly on cost model be that carry out on the basis, generation feature according to cost model, Path selection is divided into the two kinds of processes in layer choosing footpath and levels choosing footpath, with layer choosing footpath is the range algorithm, levels choosing footpath is a degree of depth algorithm, Path selection request is exactly the combination by dual mode, crosses one another, and finishes the selection of optimal path at last.The levels Path selection is exactly that primitive by C/S is realized, request last time directly entrust to lower floor realize (Fig. 5 image expression the levels algorithm selected); With choosing footpath between the layer be divided between network object and network object in two kinds, Path selection is exactly to select connection between the subnet according to cost between network object, only has annexation between network object, do not have intermediate point, and the quantity that connects is generally seldom;
The choosing footpath is the most complicated in the network, adopts the algorithm of ' breadth First ' at this level.(the Path selection reference point must be the network edge point at first to select the Path selection reference point, and be the node of upper strata appointment, determine), obtain and all alternative connections of selecting the reference point direct correlation according to cost model figure relation, according to the cost alternative condition, determine the connection an of the best then; When determining best the connection, the best of selecting reference point to move to connect a last reference point connect to end points, by that analogy, up to the output marginal point of network.Determining of output marginal point generally also is upper strata appointment when entrusting, and determines.
Illustrate this algorithm below.(this figure only reflects the situation before the following request execution to certain network choosing footpath figure of following Fig. 6, the path of selecting is after quilt deployment business, choosing footpath figure will change), (wherein node 10 to represent the fringe node of this network from the node of end surplus among the figure, 11 are connected to same external network), the node of ash end surplus is a network node, and the node of black matrix wrongly written or mispronounced character is the node (these nodes all are intermediate nodes) by the service fulfillment path process of determining after selecting; Solid line is that internodal circuit connects, and heavy line is represented the result of Path selection, and fine line is represented the possible path in the two paths selection courses; The numbering of this node of numeral in the node icon in network, the numeral on the solid line is the cost of circuit.
Require: selecting one to serve as the input node with node 1, is a path that cost is minimum of output node with 10 or 11;
[service features of the all-network node in the supposition among Fig. 6 all satisfies business demand]
Arthmetic statement: be the center at first with node 1, adopt wave pair to scan with the node that it directly links to each other, obtain all alternative path nodes (as 2 among Fig. 6,3,4), the node (circuit between the node 3 among Fig. 6 and 1 and 3 is connected) of selecting qualified path and passing through according to choosing footpath rule; Next be the center with 3, adopting uses the same method proceeds (note: the node of having selected can not be used as alternative node again), until arriving output node.In the process of selecting, certain node can occur all is identical cost (as the situation of node 5) to all paths of its next node, this is just need go on foot node down with regard to each to carry out respectively, obtain all alternative paths, concentrate from all paths of having selected at last and select the most qualified path (collection) again; Because the complexity of network, the situation that also can open circuit in the process of choosing footpath (in Fig. 6, if the cost of circuit also is between 6-4,4 to be starting point, just do not had the path that can select at 1 o'clock, at this moment, just abandon by this paths.
The result: follow above-mentioned algorithm, the end product in choosing footpath is: 1-3-5-6-9-11;
The result of Path selection must be the one or more of orderly combinations that can carry out the network object of service parameter configuration operation.
Seven, control about the affairs in the Business Processing process:
The front and back of service fulfillment, caused the change of network and resource object attribute and feature, particularly for the configuration that can relate in the service fulfillment process end to end to all or a plurality of network element devices on the entire path, the consistency of configuration data and integrality on the entire path are the emphasis problems that the service fulfillment configuration must be handled.In CAP, introduced transaction processing facility.
This notion of affairs (Transaction) is to use in database field at first, has effectively guaranteed the integrality and the consistency of data in the database.The affairs notion here and the notion of database field are consistent, and different is to be applied in the service fulfillment layoutprocedure control of field of telecommunications.
In CAP, affairs comprise two aspects (following Fig. 7): one is the affairs of service-oriented, has guaranteed the operational consistency of each business configuration involved network equipment in opening; Another is towards each network equipment, and what guarantee a business opens the integrality of configuration order on equipment; That is to say that affairs control is hierarchical control in CAP, the control of first top aspect is the user oriented service request, and a back control is network-oriented equipment.
In the affairs controlling Design of CAP, the minimum unit of affairs is service request action of configuration of opening at single network equipment, a service request is to have the combinations of transactions of a plurality of minimum units to form, CAP affairs controller is finished the decomposition of operation layer affairs to minimum transaction units, and monitors and manage the lifetime of each minimum transaction units.
The affairs control of CAP possesses stronger service feature, the life management of affairs can be carried out flexible configuration according to different service fulfillment features, such as for service fulfillment end to end, the minimum transaction units failure of in the whole service affairs any one, any one equipment disposition failure on the whole service path just, whole affairs are failure just, all rollbacks, operation layer affairs and mechanical floor affairs are one, no matter be that operation layer is handled or the mechanical floor configuration, arbitrary appearance failure, then whole service layer affairs and all rollbacks of mechanical floor affairs; Access service for multiple spot, each some configuration in the multiple spot is independent of each other, operation layer affairs and mechanical floor affairs are discrete, such as the MPLSVPN service fulfillment, affairs control is controlled minimum unit with regard to only needing, and guarantees the transactional of each point, a single point open configuration failure, do not need whole service layer affairs are carried out rollback, but the failure of operation layer transaction then will inevitably have influence on the mechanical floor affairs.
Therefore, the affairs of CAP control is the expanded application of the notion of affairs at the field of telecommunications service fulfillment, divides by the affairs of two levels, makes the more abundant of affairs and service feature combination, more meets the demand in field.
