| Abstract: | This paper designs and implements a high-precision network emulator based on protocol filtering by employing network driver interface specification technology based on Windows platform. The emulator is capable of emulating various kinds of the network transmission conditions of WAN links in real-time, including network bandwidth, packet loss, transmission delay, and out-of-order transmission. Experimental results indicate that the network emulator achieves high-precision, low-load design requirements. Realization of the emulator can help to study the QoS of multi-media network applications, analyze network protocol, and verify network control algorithms. |
