A Quality Based Foundation for IP Network Multiplexing

Why Just Add More Bandwidth Does not Work Well in Access Networks

Trading Best Efforet for Managed Reliability

This report lays the foundation for further reports on the efforts of Predictable Network Solutiuons a consultancy that has been offering a paradigm changing approach to the issue og Quality of Service in IP networks. Telecommu nications networks both analogue and now digital have been based on the application of multiplexing which is to say thew weaving together of  shared traffic  in a wy such that the flows in a way such that ideally users feels as though they have the infrastructure all to themselves.  With thge huge growth of traffic at the end of two decadesa of tghe ckommercial internet, this feat is getting more and more difficult to pull off in any kind of coat effecvtrive way.

Our report examines the basic approach of neil Davies ansd associates in building a multiplexing that assumes one no longer trties to stuff the maximum amount of data through a pipe.  Rather networks that are  sustainable from here on will strive to balance load and responsiveness in a new approach to multiplexing. Thi sshort issue introduces the basic concepts.
