Embodiment 1

[0042] Example 1 Establishing a Metamodel

[0043] First, domain experts and modelers abstract domain knowledge and establish domain metamodels through domain tools. Including the establishment of domain concepts and domain relationships and domain constraints, as well as icons presented by model elements, views of the internal structure of complex model elements, and so on.

[0044] image 3 Is a specific network domain meta-model.

[0045] The meta-model shows that a network topology diagram includes one or more meta-model elements: router (Router), switch, host (Host). In addition, the relationship between each element also needs to be included as a meta-modeling element. Including association relationship and aggregation relationship. A router and a switch may contain one or more ports (Port), which are represented by an aggregation relationship, and links between a router and a switch, and a switch and a server are represented by an association relationship. At the sa...

Embodiment 2

[0050] Example 2 Establishing a model

[0051] When modeling, corresponding model objects can be established according to various types of elements and their relationships established by the domain meta-model.

[0052] Such as Figure 4 As shown, a network model is established, that is, the core of the network uses two CoreBuilder9000, and they are interconnected through two Gigabit Ethernet links, which not only improves the reliability, but also increases the connection between the two devices. bandwidth. Each CoreBuilder 3500 is connected to different CoreBuilder 9000 through 2 optical fiber Fast Ethernet links, and all servers are inserted with 2 network cards, which are respectively connected to different core switches, thus forming a network backbone with high reliability and high bandwidth . When you want to establish a link between routers, switches and routers, the constraint validator of the domain model tool will perform verification to ensure that this modeling ...

Embodiment 3

[0053] Example 3 Verify the correctness of the model

[0054] (1) Syntax mapping

[0055] Carry out grammatical mapping on the network domain model diagram, and map it into a logic diagram represented by xKL. This part of the function is realized by a converter from graphic elements to text elements. The converted code is as follows:

[0056] abstract class Device{

[0057] / / Indicates the aggregation relationship between Device and Port

[0058] attribute ports: Port[1..*]

[0059] attribute deviceType: String

[0060]}

[0061] class Router extends Device{

[0062] attribute cpuNum: Integer

[0063] property fastEthNum:Integer

[0064] getter is done

[0065] this.ports.each{e|

[0066] if (e instance of FastEthernet)

[0067] result:=result+1

[0068] }

[0069] end

[0070] / / Association from Router to Switch, and specify your participating role name

[007...

Abstract

The invention relates to a modeling method, belonging to the field of telecommunication, which is based on executable meta languages and belongs to the technical filed of telecommunication network management. The method is more particularly relates to the modeling method for the network equipment, the network properties and the network faults in the filed of telecommunication as well as a verification method thereof. The key for realizing a modeling process is an executable meta language xKL which is suitable for the field of telecommunication. The executable meta language guides an element modeling process, describes and dynamically instantiates a field model as well as validates and executes the instantiated model so as to ensure that the generated model is executable. The method has the advantages of having excellent flexibility and adaptation; having excellent reusability; having the performability of an object model; the field model can build an excellent mapping relation betweena system requirement and a bottom layer realization; can shorten the launching time of a product, improve the product quality and increase the satisfaction of a client.

Description

technical field [0001] The invention belongs to the technical field of telecommunication network management, and in particular relates to a modeling method of network equipment, network performance and network failure in the telecommunication field and a verification method of model correctness. Background technique [0002] With the rapid development of the telecommunication industry, the competition among various telecommunication operators is becoming increasingly fierce, and the rapidly developing user group, diversified business and business competition environment put forward higher and newer requirements for the service quality of telecommunication enterprises. Facing market challenges, telecom operators need to improve management efficiency and network management level. Therefore, it is imperative to build a cross-platform integrated network management system. This platform can intuitively, comprehensively and quickly analyze and judge the operation quality of the op...
