TCPSpeaker: clean and dirty sides of the same slate

As new approaches toward clean-slate network transport continue to emerge in the wireless domain and beyond, so grows the difficulty of conducting reproducible, head-to-head evaluation and comparison of such protocols against one another. The challenge alone of clean-slate transport protocol deployment onto end-user systems makes evaluation on existing networks with real user traffic impractical. To address these challenges, we present TCPSpeaker, a transportprotocol translator designed to enable clean-slate transport to run and be evaluated in today's networks. Built on the Click Modular Router, TCPSpeaker is a tool to enable clean-slate transport approaches and evaluation in applesto-apples fashion, on existing networks with live, real enduser generated traffic. We present the design and implementation of our tool, highlighting an initial use case along with a performance evaluation.
