What's New

Pathrate v2.1.1 is now available. Pathrate is an end-to-end capacity estimation tool for Internet paths. This second version of pathrate is based on our recent study of packet-dispersion effects.

``Class Provisioning Using Proportional Delay Differentiation'', with P.Ramanathan. To appear at the ``Scalability and Traffic Control in IP Networks'' conference (SPIE ITCOM304), Denver CO, August 2001.

``Dynamic Class Selection: From Relative Differentiation to Absolute QoS'', with P.Ramanathan (to appear at ICNP 2001).

``What do Packet Dispersion Techniques Measure?'', with P.Ramanathan and D.Moore (Infocom 2001). A revision of this paper, with additional results, is also available (submitted to the IEEE/ACM Transactions in Networking).
