Lessons Learned Evaluation Platform Evaluation platform is useful for investigating DTN algorithms evaluation platform can be effectively leveraged in next phase Virtualization (User-Mode-Linux) proved to be a useful tool requires host and guest kernels to be configured initially Ns-2 emulator worked out well, but required significant effort many interactions had to be dealt with frequency scaling, ACPI, hyper-threading affect correct operation interactions between nse scheduler and Tcl/expect scripting we offloaded traffic generation entirely to UMLs Platform is compute-bound, emulated network is not congested certain scenarios can overload even a 4-way SMP system especially if the number of records in the KB goes into the hundreds running emulator at higher priority helps somewhat |
