Paper Title: A Datastream Language for Protocols Letter grade: B- Numeric grade: Confidence Comments: Good paper, It wasn't clear who the audience was for these protocols. Are they intended for protocol designers working in the operating system, or for application designers who would like to try ILP and ALF? The paper is interesting, and should be in the workshop, but I believe that the authors must deal with two concerns before they get to the workshop: - the paper is motivated by performance, but there is no data to yet indicate that this is a good idea. In fact, intuition suggests that this approach will result in protocols that run more slowly than conventionally structured protocols. The authors may have some insight into why this intuition is not applicable, but they've not done a good job of presenting that insight. - the authors don't make a convincing case that something real, beyond very simple protocols, could be built. The other paper on automatic protocol construction (header prediction) is substantially stronger than this one, so if there are limited slots, the other one should be taken.
