A method and system for dynamically configuring network simulator event queues

Abstract

The invention proposes a method and system for dynamically configuring the network simulator event queue. The method for dynamically configuring the network simulator event queue includes: step 1, constructing a virtual network topology, and initializing the event queue of the network simulator; step 2, creating a parent process; step 3, controlling the parent process to create a child process; step 4, controlling The current child process executes the scheduling task of the current event queue, and the parent process monitors the user's dynamic configuration signal in real time; step 5, judge whether the parent process has listened to the dynamic configuration signal, if so, end the current child process, and the parent process adds the dynamic configuration signal to the event queue event, return to step 3, otherwise, return to step 4. With the present invention, after the network simulator is running, events can be added to the event queue according to user needs, and by creating parent-child processes, the network simulator can be clearly managed, so that the network simulator continues to schedule subsequent events in the event queue at a specific point in time. event.

Description

technical field [0001] The invention relates to the technical field of network simulation, in particular to a method and system for dynamically configuring a network simulator event queue. Background technique [0002] With the development of virtualization and network simulation technologies such as simulation and emulation, more and more researchers use virtual machines, network simulators, and appropriate physical equipment to build virtual network environments instead of complex and time-consuming physical test environments. It means that the network simulator has become a basic tool for network activity research such as network technology research, tool testing, scene reproduction and backtracking deduction. [0003] The network simulator is based on the scheduling framework of discrete events, and realizes the complete simulation of network behavior through the network simulator engine. The so-called discrete event system means that the state of the system changes at ...
