[Nets-seminars] Talk tomorrow, Friday 23rd, 4pm GS/302

[Richard G. Clegg]

Don't forget tomorrow's talk by Bob Briscoe from UCL computer science 
and also BT.  Should be a fascinating one.

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.
