Kandula et al (2005) Walking the Tightrope: Responsive Yet Stable Traffic Engineering (SIGCOMM)

October 21, 2009 paper

This paper is about how to do traffic engineering in a multipath network, so that traffic can be splitted to different paths and in the same time, change the splitting ratio to adapt to network utilization levels. [more]

GDB 7 on OS X

October 21, 2009 blog system

GDB 7 is released. It is nice to know that it now supports Darwin systems, a.k.a. Mac OS X. [more]

Downey (2007) TCP Self-Clocking and Bandwidth Sharing (ComNet)

October 19, 2009 paper

This paper describes the case when the congestion window of a TCP is greater than the BDP. The BDP is defined as the bottleneck bandwidth multiplies by the end-to-end propagation delay. It finds that, in such scenario, the TCP is undergoing self-clocking transfer which means the cwnd does not play... [more]

Bansel et al (2001) Dynamic Behavior of Slowly-Responsive Congestion Control Algorithms (SIGCOMM)

October 16, 2009 paper

This paper evaluates different flow control algorithms and it is the first to propose the term “TCP-Friendliness” or “TCP-Compatible”. The motivation is that, a lot of algorithms are proposed to date to avoid the TCP’s AIMD, which changes the rate too drastic and thus not suitable for media streaming use.... [more]

Laor and Gendel (2002) The Effect of Packet Reordering in a Backbone Link on Application Throughput (IEEE Network)

October 16, 2009 paper

A paper in the early year to investigate the effect of packet reordering to application throughput (esp. TCP). The conclusion is trivial but it gives some numbers: [more]
