System and method for seamlessly accessing physical equipment to network emulator

Abstract

The invention relates to a system and a method for seamlessly accessing physical equipment to a network emulator. The system comprises the physical equipment (such as a host and a router), a physical equipment access system and the network emulator, wherein the physical equipment access system comprises an ARP (Address Resolution Protocol) response module, an access test module, a packet capture device module and a repeater module, the ARP response module is used for guaranteeing that all data packets sent from the physical equipment reach a network card monitored by the system first, the access test module is used for detecting access information of the physical equipment in real time, the packet capture device module is used for capturing real network data packets sent by all the accessed physical equipment and forwarding the real network data packets to other modules in accordance with types of the real network data packets, and the repeater module is used for transforming and forwarding virtual network data packets and the real network data packets. The method for accessing the physical equipment to the network emulator, which is disclosed by the invention, corresponds to the system. The method can be used for seamlessly accessing the physical equipment and accessing a real router.

Description

technical field [0001] The invention relates to the field of network simulation, in particular to a system and method for realizing seamless access of physical equipment to a network simulator of a network simulation platform. Background technique [0002] Network simulation is an important method for studying large-scale networks at present. It is favored by network researchers because of its advantages such as high authenticity, large simulation scale, low development and operation costs, and can be used to study current and future network behaviors. . However, network simulation also has disadvantages: 1) Some parameters affecting performance that must be set before running the network simulation model are difficult to determine, and sometimes it is difficult to give reasonable values ​​or even correct modeling. For example, the time it takes for the CPU to process an instruction is usually affected by the CPU cache and whether it is multi-core. 2) Network simulation do...
