Bob Briscoe (Chief researcher at the BT Network Research Centre) is on a mission to tackle one of the biggest problems facing the Internet. He wants the world to know that TCP (Transmission Control ...
In December, we wrote about researcher Bob Briscoe's problems with TCP's fairness in handling different protocols. Specifically, unattended peer-to-peer bulk data transfer applications (e.g., ...
It’s hard to imagine now, but in the mid-1980s, the Internet came close to collapsing due to the number of users congesting its networks. Computers would request packets as quickly as they could, and ...
We previously wrote a newsletter about the TCP window size (see link below). The responses we received to that newsletter convinced us that we should occasionally devote future newsletters to ...

One of the major requirements of any network is high speed and reliable communication. TCP itself provides such high speed communication over the dedicated channel to perform the dedicated and ...
Bufferbloats—an amusing word for a less-than-delightful issue (we reported on these last year). A bufferbloat is the proliferation of more and more buffering of IP packets in routers, switches, modems ...
On Thursday the 14th of November 2019, M.Sc. Ilpo Järvinen will defend his doctoral thesis on Congestion Control and Active Queue Management During Flow Startup. The thesis is a part of research done ...
