It's really not that tough, and most apps/devices have them today because working products sell better than non-working ones. My VoIP phone (full disclosure: I work for the vendor) operates just fine at home over a DSL line, across four ISPs, through two NATs, and to a gateway in Canada. The voice gets a little choppy when a 10MB powerpoint hits my Inbox (sadly, several times per day), but it self-corrects after a couple seconds. > Doesn't anyone really remember the whole smart-v.-stupid network > analogy?

I think you'll get further by arguing that intelligent networks with small pipes cost more to maintain than dumb networks with fat pipes. Less likely to induce sleep in your bean-counters.

Google to Open Research Facility in Pa.

This story was sent to you by: Fergie -------------------- Google to Open Research Facility in Pa. -------------------- By DANIEL LOVERING AP Business Writer December 15, 2005, 10:27 PM EST PITTSBURGH -- Google Inc., the leading online search engine company, will open a new engineering and research office in Pittsburgh next year to be headed by a Carnegie Mellon University professor, the company said Thursday. The facility will be charged with creating software search tools for Google. It is expected to create as many as 100 new high-tech jobs in the Pittsburgh area over the next few years, said Craig Nevill-Manning, director of Google's New York engineering office. The office will be headed by Andrew Moore, a Carnegie Mellon professor of computer science and robotics who currently runs a research laboratory of 30 students, programmers and faculty members. Moore, 40, is an expert in data mining and artificial intelligence. "Andrew Moore has built his career on the twin challenges of developing techniques to extract patterns from large data sets and applying these machine learning methods to real-life problems," said Randal Bryant, the dean of Carnegie Mellon's computer science school. The office will be one of several Google has opened near universities. The company recently joined Microsoft Corp. and Sun Microsystems Inc. in backing a $7.5 million Internet research laboratory at the University of California, Berkeley. It also has facilities in New York, Phoenix, Santa Monica, Calif., and Mountain View, Calif., where the company is based. Google has overseas offices in Japan, Switzerland and India. * __ On the Net: Google: http://www.google.com Carnegie Mellon University: http://www.cmu.edu Copyright (c) 2005, The Associated Press -------------------- This article originally appeared at: http://www.newsday.com/technology/wire/sns-ap-google-carnegie-mellon,0,3281… Visit Newsday online at http://www.newsday.com

I certainly don't endorse placing _all_ of the intelligence in the application, but look at it this way -- if you expect to have a 'stupid' CPE handset rely on 'intelligence' in the network for voice quality, you're probably going to be disappointed. And no amount of leveraging smoke-and-mirror QoS frobs to generate additional revenue will help you out. :-) $.02, - ferg -- Sean Donelan <sean(a)donelan.com> wrote: On Fri, 16 Dec 2005, Fergie wrote: > Doesn't anyone really remember the whole smart-v.-stupid network > analogy?

Trying to stick it all in the application is not exactly a win-win proposal either. The problem with religious dogma is it leads to a lot of burning people at the stake, for more stupid analogies. Finding the right blend of what applications can do well, what the network can do well, and how they interact is the challange. For example, smart applications don't handle DDOS attacks very well, and regardless of how much network capacity you provision, there is always a DDOS that is bigger. -- "Fergie", a.k.a.

Grant vs. Stern: animosity or respect?

This story was sent to you by: Paul "Fergie" Ferguson -------------------- Grant vs. Stern: animosity or respect? -------------------- ANDY EDELSTEIN December 15, 2005 There's a connection between the two provocative New York radio personalities who will soon be leaving their longtime gigs. Bob Grant was one of Howard Stern's radio heroes. As a Long Island high-schooler in the early 1970s, Stern avidly listened to Grant's afternoon talk show on WMCA. The once and future radio talk titans even met each other. Grant told Paul D. Colford, author of the 1996 Stern bio, "Howard Stern: King of All Media," about being approached at a public appearance by Ben Stern, Howard's father, his teenage son in tow. Father introduced son to Grant and told him of Howard's desire to go into radio. "I looked at this big, gawky kid and I said to him, 'Just be yourself,'" Grant recalled. Obviously, Stern took Grant's advice to heart. And in a 1985 interview with CNN's Larry King, when Stern was asked which broadcast personalities he liked, the soon-to-be king of all media could only name one: Grant. But, Colford notes, as Stern's popularity increased, he began changing his opinion of Grant - at least in public. Grant always thought Stern's new, more negative assessment was just "part of his act."

Because there is more to it than just that. :) there is the matter of whether they are represented by 2 bytes, or 4 bytes _in_transmission_. '0x00004F4F' is a '4-byte' AS number that has a value less than 65,536. It _should_ be treated identically with the 2-byte AS number '0x4F4F', as I understand the currently-proposed methodoloty, but there is no intrinsic reason why that _must _be the case. A two-byte AS number, and a 4-byte AS number with the SAME numeric value, _are_ distinguishable as =different= entities. > > 1.

Is it? <grin> Do you represent AS 17 in two bytes, or four? if you use 2 bytes, do you, "somewhere down the road", change to representing it with 4 bytes? or do you deal with 'mixed-length' codes "in perpetuity"?

Imposter: Google to Open Research Facility in Pa.

All: I did not sent this crap to the list. As has happened before, someone obviously thinks it's funny to spam the list from a web-based e-mailer at tribuneinteractive with my name. - ferg ---------- Forwarded Message ---------- This story was sent to you by: Fergie -------------------- Google to Open Research Facility in Pa. -------------------- By DANIEL LOVERING AP Business Writer December 15, 2005, 10:27 PM EST PITTSBURGH -- Google Inc., the leading online search engine company, will open a new engineering and research office in Pittsburgh next year to be headed by a Carnegie Mellon University professor, the company said Thursday. The facility will be charged with creating software search tools for Google. It is expected to create as many as 100 new high-tech jobs in the Pittsburgh area over the next few years, said Craig Nevill-Manning, director of Google's New York engineering office. The office will be headed by Andrew Moore, a Carnegie Mellon professor of computer science and robotics who currently runs a research laboratory of 30 students, programmers and faculty members. Moore, 40, is an expert in data mining and artificial intelligence. "Andrew Moore has built his career on the twin challenges of developing techniques to extract patterns from large data sets and applying these machine learning methods to real-life problems," said Randal Bryant, the dean of Carnegie Mellon's computer science school. The office will be one of several Google has opened near universities. The company recently joined Microsoft Corp. and Sun Microsystems Inc. in backing a $7.5 million Internet research laboratory at the University of California, Berkeley. It also has facilities in New York, Phoenix, Santa Monica, Calif., and Mountain View, Calif., where the company is based. Google has overseas offices in Japan, Switzerland and India. * __ On the Net: Google: http://www.google.com Carnegie Mellon University: http://www.cmu.edu Copyright (c) 2005, The Associated Press -------------------- This article originally appeared at: http://www.newsday.com/technology/wire/sns-ap-google-carnegie-mellon,0,3281… Visit Newsday online at http://www.newsday.com
