Router Benchmark

acceptance/router_benchmark/benchmark.py is a tool to benchmark an external router.

The usage is simply: acceptance/router_benchmark/benchmark.py.

Without any options, the tool outputs instructions. Those instructions comprise how to configure the subject router and how to re-execute the tool so it actually carries the measurement.

In order to accomplish the tool’s instructions one will need to:

• run two microbenchmarks on the subject router: coremark and mmbm.

• configure scion-router on the subject router with a custom configuration and topology.

• configure two of the subject router’s interfaces.

• connect these interfaces to two interfaces of the host where benchmark.py is going to run.

If the subject router is an X86_64 platform running Openwrt, then one should install the package scion-bmtools, which will not only configure scion-router for benchmarking, but will also run the coremark and mmbm microbenchmarks and make their results available for pickup by benchmark.py.

Otherwise these operations still have to be carried out manually. The mmbm and coremark tools can be found in: bazel-bin/tools/mmbm/mmbm_/mmbm and bazel-bin/tools/coremark/coremark.
