Has anyone seen this? http://www.real-internet.org/whatisric.txt "It is widely recognized that, because of the speed limitation of electric circuit, Tbps or Pbps routers can be constructed only with massively parallel architecture with a lot of elementary routers combined by a high speed interconnection backbone. On the other hand, it is widely misunderstood that fine grain QoS assurance of individual flows is impossible, because, at the high speed backbone of the Internet, there are so many flows that signaling of the flows and routing (including policing and fair queuing) of packets of the flows do not scale. It is not widely understood that the backbone scalability problems of QoS assurance is solved by massively parallel nature of high speed routers. As a result, people in conventional standardization forum such as ISO, ITU and IETF are, in vain, trying to produce complex protocols to aggregate flows to reduce the complexity. However, it is easy to prove that such aggregation is impossible at least with multicast or QoS routed flows. Thus, in some IETF WG, QoS assurance is finally given up and CoS assurance, which is not useful for most applications, which is often obfuscated by the fallacy of calling CoS QoS, is pursued."

RealMedia feed
by Bora Akyol 12 Jun '00

12 Jun '00

The real media feed from the conference is very spotty and the server seems to be loaded too. Is it possible to drop the rate to 32 Kbps or 64Kbps from 80Kbps and get at least good quality sound instead of nothing at all? Bora

Re: GAO report on outages at online trading sites

There's a lot of interest in Washington in Internet outage reporting, as soon as they can figure out what an outage is and who should report it. But defining the criteria is very hard, as I'm sure I don't have to tell people on this list. --Steve Bellovin

Broken 3640?
by Jason Slagle 12 Jun '00

12 Jun '00

We have a 3640 on the edge running 12.0(9.6)S. It has 2 2W1E's with T1-DSU WIC's in it and 1 1FE NM. About once every minute, the FE card stops sending packets for about 10 seconds resulting in a HIGH and very annoying packet loss. Tries 12.0(10.x)S and replacing the FE cards to no avail. Also, the card has stuck 5 or 6 times with the output queue at 240/240 with no network activity until I reboot it. I'm at a loss here. Any ideas?

GAO report on outages at online trading sites
by Sean Donelan 12 Jun '00

12 Jun '00

Another government agency weighs in on the lack of public reporting of outage information. Early this year the FCC was working on a "voluntary" method for ISPs to report outages. So far, I haven't heard of a single ISP voluntering. This week the General Accounting Office issued a report on online trading web sites, and the lack of disclosure about network problems and system outages. http://dailynews.yahoo.com/h/is/20000609/bs/watching_the_stock_watchers_1.h… > Watching the Stock Watchers > (The Industry Standard) > When a system outage occurs at your online brokerage, the only way you might > find out is if you're stuck in the middle of a trade or if the media reports > the outage. But it happens more frequently than is reported. > > Many outages occur in small geographic areas and for just a short amount of > time. But brokerages aren't required to disclose these outages to customers, > the Securities and Exchange Commission or to any other regulatory body. Many > times they don't even keep records of their own on small outages. > > The U.S. General Accounting Office has a problem with that. [...] The full GAO report is http://www.gao.gov/new.items/gg00043.pdf One interesting statistic was 11 firms reported a total of 88 outages between January and September 1999. About 40 percent of the outages lasted for less than 25 minutes, but some firms didn't track any outage lasting less than 25 minutes. So there may be a statistical problem with the data. For comparison, the telephone industry reported a total of 170 outages between July 1998 and June 1999. The telephone industry doesn't track most outages lasting less than 30 minutes (except for a few special catagories). Even if you normalize for 3/4 of a year, it seems the Internet is actually more reliable than the telephone network. Or, what I suspect is really happening, both the telephone industries and the online brokers statistics are measuring the wrong stuff. But the real $64000 question is during periods of market volitility, would you be able to reach a broker by telephone easier than you would be able to access an online trading web site. The GAO didn't really answer that question.

Traditional traffic engineering tools/model
by Yu Ning 11 Jun '00

11 Jun '00

Hi nanog, Can any friend tell me that how the major NSP/ISPs do the traffic engineering work, i.e. how do they adjust their traffic to fit their physical bandwidth? I know there are several papers on this issue by Awduche of UUNet, and some engineers of Juniper. Most of them suggest MPLS is the final solution, but I just want to know if there is any best practice to adjust the traffic in a pure igp/metric fashion ? Any handy tools to figure out, or calculate the proper metric value? I tried Netsys, but any better one ? We use i-isis as igp, so any isis specific method ? thanks for any input. best regards, Yu Ning ------------------------------------------- (Mr.) Yu(2) Ning(2) ChinaNet Backbone Operation +86-10-66418105/66418121/66418123(fax) -------------------------------------------

Brown runs IHighway, an Internet access firm in Albuquerque, New Mexico. He'd like to give his clients the fastest possible link to the rest of the web world--but he can't.

And Brown can't afford $120,000 a year to lease a pipe running 530 kilometers to the UUnet hub in Phoenix, Arizona.... --------------------------------------
