[Nets-seminars] Talk next Friday (23rd October) 4pm GS/302

[Richard G. Clegg]

Next Friday's talk is by Bob Briscoe from UCL CS and also BT.  It should 
be very interesting indeed.

Mending the Internet Value Chain... in One Bit

This talk shows that capacity sharing in packet networks has reached an
impasse, and offers a far better way forward. Ideally, everyone should
be free to use as much of the Internet resource pool as they can take.
But, whenever too much load meets too little capacity, everyone's
freedoms collide. Attempts to isolate users from each other (fair
queuing, usage & rate caps) have corrosive side-effects - discouraging
mutually beneficial ways of sharing the resource pool and harming the
Internet's evolvability. The talk also explains why TCP-fair congestion
controls are part of the problem, not the solution. Instead, an unusual
form of traffic policing is described that only pushes back against
those who use their freedom to limit the freedom of others. This offers
a vision of how much better the Internet could be (and all
multiple-access shared networks). To reach this future, a change to the
Internet Protocol has been designed using the last available bit. The
talk ends by reporting on the status of standards activities at the IETF
and elsewhere.
