Abstract

Driven by lacking of a low-cost, large-scale, flexible and reconfigurable general purpose network emulation platform for space networking, ISTIN laboratory of Nanjing University designed a flexible and fully reconfigurable space network emulation platform supporting emulation of multiple network architectures and network protocols. We have carried out some space network protocol research based on the platform, such as DTN and IP. This paper constructs a spatial network scenario to evaluate OSPF and OSPF+ routing performance on this platform The emulation results indicate the emulation platform has the ability of IP routing emulation, which guarantees considerable reliability and provides a reference for subsequent emulation work of IP protocols.
