Abstract
Based on the previously developed network emulator named MininetE [1], this paper proposes an improved scheme of lightweight network emulator for large-scale space information network (SIN) emulation. The improved MininetE still has the ability to emulate network link characteristics such as bandwidth, latency and packet loss, while generating real network traffic. Through the setting of network configuration parameters, not only DTN protocol but also IP-based OSPF protocol can be run in the new MininetE, making it possible to build a SIN emulation environment where multiple network protocols coexist. Based on this, a SIN scenario with the improved MininetE is constructed to evaluate the performance of OSPF and the coexistence of OSPF and DTN respectively. The results show that the emulation platform has the DTN and IP-based routing emulation capability and ensures considerable reliability, which provides a reference for further optimization of MininetE emulation platform in the future.
