Research on High-Fidelity Router Emulation Technologies Based on Cloud Platform

A cloud platform that incorporates virtualization technologies, and SDN technologies has the advantages of strong scalability and a high fidelity of host node emulation. However, this type of cloud platform is not designed specifically for network emulation, and the shortcoming of low fidelity remains in router emulation. For this reason, based on the cloud platform, this paper combines virtualization technology with router software technology, proposes a programmable router emulation method that supports multiple routing protocols, and designs a highly realistic congestion control strategy emulation scheme. Experiments show that the proposed router emulation scheme can support the emulation of multiple routing protocols while maintaining high fidelity in virtual router congestion control.
