Description

technical field [0001] The invention belongs to the field of network simulation, in particular to an efficient and scalable network simulation scene generation method. Background technique [0002] With the continuous development of information technology, the modern communication network structure is becoming more and more complex, and the network scale is becoming larger and larger. As an important means of network design, network simulation technology provides a convenient solution for network planning, protocol verification and real scene testing. Among them, it is often an indispensable link in the actual development process to test and evaluate the design scheme in advance through network simulation software. Therefore, it is necessary to provide efficient and flexible simulation systems for network designers. [0003] At present, there are many network simulation software, the well-known ones are NS 2, NS 3, OPNET, NetSim, OMNeT++, J-Sim, QualNet and Mininet, etc. (i...

Problems solved by technology

[0004] Although the above-mentioned simulation software has its own characteristics, they all have obvious disadvantages: First, the operation is complicated and the learning cost is high. Designers often face some inherent simulation problems, such as having to spend a lot of time learning in order to use a specific simulation function. Corresponding software development environment

[0006] To sum up, because the information of network simulation scenarios is universal, but different network simulation software has different modeling mechanisms, and the original modeling mechanism has problems of insufficient flexibility and low efficiency. Therefore, considering the network description Due to the versatility and scalability of the language, it is necessary to apply the network description to the field of network simulation, and propose a simulation scene generation mechanism with a unified interface, which is widely applicable to a variety of simulation software, and provides high semantic abstraction
