I'm on board with that as far as it goes, but has the scenario of adjustable launch powers so that you don't ever need attenuators plus the economy of scale that would come from having *one* type of interface for 1m-10km runs been considered? It seems to me based on what I've seen of the optics market that once you make something a mass-produced commodity the price falls awfully far - suppose the price difference was $250 vs. $375, that's a big difference on a percentage basis but pocket change on an absolute basis. ---rob > > Chris > > -----Original Message----- > From: Robert E.

Hi, I am looking for a typical percentage of external(inter-domain) routes versus typical percentage of internal (intra-domain) routes in a core router with couple of hundred thousand entries in the routing table. Can anyone please help me in this? Best Regards, Sana Sohail

Creating a crystal clear and pure Internet
by Sean Donelan 05 Dec '07

05 Dec '07

Some people have compared unwanted Internet traffic to water pollution, and proposed that ISPs should be required to be like water utilities and be responsible for keeping the Internet water crystal clear and pure. Several new projects have started around the world to achieve those goals. ITU anti-botnet initiative http://www.itu.int/ITU-D/cyb/cybersecurity/projects/botnet.html France anti-piracy initiative http://www.culture.gouv.fr/culture/actualites/index-olivennes231107.htm

Is anyone aware of recent by-protocol traffic data in the public domain?
by Alexander Harrowell 05 Dec '07

05 Dec '07

Excellent public studies of Internet traffic by protocol exist from NSFNet times up to 2002 or 2003; we thank Odlyzko, Claffy et al for their work. However, has anyone else noticed a serious lack of data after the end of the studies summarised in "Longitudinal study of Internet traffic 1998-2003", Fomenkov, Keys, Moore & Claffy, 2003? (This has been discussed in the past, I think.) All that seems to be available is vendor handwaving of the sort Andy Odlyzko takes so much trouble to debunk; and that without any source data. Curiously, no-one seems to be funding this stuff in Europe, either. Alexander Harrowell

http://www.theaustralian.news.com.au/story/0,25197,22869272-15306,00.html Southern Cross Cable operations vice president, Dean Veverka, has confirmed that hurricane-strength storms and flooding have wiped out the carrier's Oregon cable route and halved its bandwidth between Australian and the US. Southern Cross's customers in Australia include iiNet, Internode and AAPT.
