Where does most of the latency come from? Routers.
Uhh... what about longlines??
MAEs and NAPs are yesterdays ideas that everyone who has bought into the concept now has to live with it, they did not build the business around the fact they had to pay and manage to provide good service.
Hey, if that's your opinion then that's fine. Most of us aren't so ready to throw out *ANY* of the tools available to us to build networks. Routers have a place, IXPs have a place and switching has a place. You do things your way and we'll do it our own ways and next year we will see who had the best ideas.
The time is almost upon us that you pay for what you get on the internet and you must pay for the bandwidth that you use, not what you can over subscribe until your customer begin to leave. This is a tough model, few will make it.
What makes it tough is that there is very low customer demand for this sort of network. Every experiment with pay-per-use communications services over the past twenty years has shown that customers don't like it. The Internet boom of 1995 demonstrated quite graphically that flat rate telecom has an outrageously strong customer demand. Our job is to figure out how to continue to scale a network that can profitably provide flatrate services. That's the bread and butter of this industry.
Some day the internet will use measurements, such as QOS and customer will be willing to pay for those who have engineered their networks to provide QOS.
Yes, definitely. But that's still an extra cost luxury over and above the flatrate bread and butter services. ANd there is no certainty that ATM will be needed to provide QOS. There are some interesting options in certain routers as well.
I only have one more question for you; how many router hops, on your network, from New York to Los Angeles? If it is more than 1, then tell me what your latency is from end to end. Let's compare, shall we.
You aren't going to make latency disappear by replacing router hops with ATM switch hops. Those electrons still have to cross the continent. ******************************************************** Michael Dillon voice: +1-415-482-2840 Senior Systems Architect fax: +1-415-482-2844 PRIORI NETWORKS, INC. http://www.priori.net "The People You Know.
