Embodiment 1

[0032] see figure 1 , the basic flowchart of the network simulation method provided by Embodiment 1 of the present invention mainly includes steps:

[0033] S101, the simulation visualization interactive process located inside the network simulation platform receives the simulation command sent by the control process located outside the network simulation platform through an external process communication mode;

[0034] In the embodiment of the present invention, it is realized based on an existing general network simulation platform (such as Opnet, NS2, Omnet and J-Sim). Among them, the simulation visual interaction (Simulation Visible&Interaction, SVI) process is located inside the platform; the control process is located outside the platform, and is used to send simulation commands to the SVI process through external process communication. Specifically, the network simulation platform can be located in one physical entity (such as a certain PC or server), while the control...

[0046] The embodiment of the present invention describes the technical solution in detail based on the first embodiment.

[0047] In the embodiment of the present invention, the control process positioned outside the network simulation platform can be generated by a third-party program, for example, by creating a GUI program through programming languages ​​and tools such as MSVC, VB, JAVA and Delphi;

[0048] The simulation visual interaction process (SVI process) and the simulation network element process located inside the network simulation platform can be generated by the simulation platform. Specifically, the simulation platform determines and generates relevant simulation models according to the simulation scenario, and then generates corresponding processes according to these models. The network simulation scene here refers to a network scene that needs to be simulated. For example, it can be an IP network, or a wireless network, or other networks that need to be simulat...

[0082] In order to illustrate the technical solutions in the embodiments of the present invention more clearly, the embodiments of the present invention are described in detail in conjunction with specific application scenarios.

[0083] With the transformation of telecommunications to IP, more and more operators carry services on IP bearer networks. When networking scenarios become increasingly complex, it becomes a major challenge for network operation and maintenance to intuitively and quickly display the routing information of data packets in the case of network stability and failure. The technical solutions provided by the embodiments of the present invention can solve this major problem, as follows Figure 4 The network fault injection and route display shown in the simulation IP scenario are taken as an example for illustration.

[0084] Assume that the host / module address of the network simulation platform in this scenario is A, and the port is B.

Abstract

The embodiment of the invention provides a network simulation method and a network simulation device. The network simulation method comprises that: a simulation visualized interactive process positioned in a network simulation platform receives an simulation command sent by a control process positioned outside the network simulation platform in an external process communication mode; the simulation visualized interactive process transmits the simulation command to a corresponding simulation network element process in the network simulation platform in an internal process communication mode; the simulation visualized interactive process receives a simulation result output after the simulation network element process executes the simulation action according to the simulation command in the internal process communication mode; and the simulation visualized interactive process outputs the simulation result to the control process in the external process communication mode, so that the simulation result is displayed and output through the control process. Through the method, a user can simulate an appointed network element required to be simulated flexibly by inputting the simulation command and can obtain the simulation result in real time so as to improve the flexibility and simulation credibility.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a network simulation method and device. Background technique [0002] With the emergence of new network technologies, the integration of different types of networks has gradually become a trend. This trend has led to an increasing number of business types in network operations and an increasingly heavy network load, accompanied by increasingly complex network structures and scales. Therefore, new technical means are required to replace traditional network planning and design. [0003] In various network planning and design, network emulation is a new technology. By establishing models of various physical objects that may be used in network operations such as equipment, links, and protocols, and simulating traffic transmission in a real network environment, network simulation can obtain performance data required for designing or optimizing a real network. From the perspectiv...
