Reviewer: Mark Meras (mm446)

Main Contribution

This paper by La and Anantharem discusses a new pricing scheme for TCP communication that would optimize total user utility using only the information available at the end hosts.

Key Ideas

Critique of Contribution

The work seems a good contribution to the set of knowledge about bandwidth pricing schemes. Its major impact is the subdivision of the problem into the user and network subproblems, allowing the users to evaluate their pricing on an end-to-end model.

Open Question

Is there a way to incorporate level pricing into the scheme, a hybrid of flat-level and per-unit pricing that allows users to pay for "levels" of access? This scheme is used in the cellular industry, for example.
