Hi Christopher, Christopher J. Wolff wrote: Jane, This brings up a good point about IM. IMHO, IM is a security risk and I am establishing a company standard where users behind the firewall are prohibited from using IM, IRC, and peer-to-peer file sharing programs. My opinion is that these types of programs contribute more to lack of productivity than to real problem solving. I think the road you've chosen is a tough one. A great many people have contributed to this who are far more experienced than I. I believe we won't see IM going away. Everyone uses it, and like all humans, make it forbidden and the people in your company will view it as all the more desirable. There are a great many management tapes and videos and books out there, and they basically say the same thing. Trust your people to do their job and don't worry if they play games or talk on IM. Measure them by the metrics you've given them. And don't sweat the small stuff. (Easy to say, I know.) My teenager can play a computer game, chat with his friends through IM and talk on the phone, all while he's writing his science report. And the reports not all that bad because I proof everything he turns in (except the French). As long as his grades are in the A-B range, I restrict nothing. well, almost nothing. But if his grades drop . . . the ax comes down. If the issue is viruses, there are a great many ways to screen viruses even through IM. I trust our staff to be sure they are all implemented. My two cents, for what its worth. I've tried micro managing and it never never (I'm restraining myself from saying never 20 times) works. So my question for the group is, do chat programs (IM, IRC, yahoo) serve a substantial network support purpose or are they more of a distraction, allowing staff to communicate with friends, relatives, drifters, interlopers on company time? I think people do this anyway, we used to chat around the coffee pot. I think its funny when office mates are chatting away on IM. People cannot produce 24/7 or even 8/5. They have to take a break every hour or so. Human nature. We have a game room here at work . . . People are going to play, so create the environment where they can.

I'm not sure what you are saying regarding filling up an OC3 with NTP, Unicast or Multicast/Broadcast? Either way it will be difficult, and take any number of computers to do. but i do know you can calculate simple latency I believe, measurements from normal NTP = but strategically analyzed from remote sources and correctly configured i.e. all s/1 or s/2 with drift. This is not so true for you folks though, NTP assumes that the outbound trip is identical to the inbound trip and with routing agreements (hot potato and otherwise) and the Routing Arbiter, this simply is not true anymore. So the 1/2 time alg. doesn't quite work right these days. I wont' say I'm the expert at this, I'm the bb wiretap guy :), not the ntp latency guy...but I've been around a bit. Well - I am one of the NTP latency guy's, and I personally operate three (3) of NIST's stratum-1 public access time servers... And I would not use NTP. As it happens most all NTP users really don't understand the NTP weighting or the physic's of impulse time propagation. Besides what you are looking for is not exact information as to the Time of Day, but the elapsed time between any two nodes of a network from the point of the commencement of your test. What you want is really a precision heartbeat and there is no better place to get one than from GPS unless you have your own local oscillator backed clocks and a regimen to keep them properly tuned and synched. My favorite way to achieve this is to get two GPS-backed clocks together and then count the bytes... Remember that packet sizes must vary too otherwise the routers get lazy. BTW - GPS offers lousy reliability as an absolute timebase because of how easy it is to spoof or shutdown in denial-of-service, and that it is physically impossible to prove anything from a GPS source for what should be obvious reasons (i.e. there are a number of passive beams of data that are correlated by the receiver and so never reproducible), but when it (GPS) is operating properly it provides the coolest 1PPS heartbeat. The heartbeat of the US Government so to speak. And as it happens, most all of the GPS Birds in orbit (24 of them) have at least Datum Cesium Beam Atomic Clocks or Datum Rubidium Clocks. So if you need critically accurate and provable time of day, what you do is to take what is called an Initialization Event from ACTS or other reliable timesetting instance, and that is jam-set into the clock's control register and you run from there. From that point on there are any number of methods of disciplining the clock base. Oh and use something like a SNIFFER to generate the traffic. Most of what we know of as commercial computer's cannot generate more than 70% to 80% capacity on whatever network they are on because of driver overhead and OS latency etc etc etc. It was funny, but I remember testing FDDI on a UnixWARE based platform and watching the driver suck 79% of the system into the floor.

Btw, if you've got a bit of time on your hands, the Click router components have some extremely-low-overhead drivers (for specific ethernet cards under Linux). They can generate traffic at pretty impressive rates. They used them for testing DOS traffic for a while. http://pdos.lcs.mit.edu/click/ (Most of the driver overhead you see is interrupt latency; click uses an optimized polling style to really cram things through). Also, the new FreeBSD polling patches should make it so you can get more throughput from your drivers when doing tests.

Re: Testing Bandwidth performance
Hi Alan, What are some tools to test bandwidth perfomance? I've used iperf, but = are there other tools or ways to generate traffic for testing purposes = to see a links maximum capacity? Especially greater than a 100mb. Iperf can be used to generate OC3+ class TCP flows above if the host configuration is correctly tuned. See, for example, the excellent paper by Stanislav Shalunov at http://www.internet2.edu/~shalunov/gigatcp/ ...and systems have only gotten better since that was written. For example, relative to what folks had available a year or so ago (which still performed quite well), you can now buy a system like the Supermicro SuperServer 6022L-6 2U ( http://www.supermicro.com/PRODUCT/SUPERServer/SuperServer6022L-6.htm ) off the shelf with: -- 2x Xeon 2.4GHz/512K L2 cache (Stas's quoted box was working with only 2x1GHz PIII CPUs) -- PCI buses which have gone from 64 bit/66Mhz to PCI-X 64 bit/133MHz -- DDR with 2 way interleaving is now an inexpensive production memory option (the quoted box had used SDR) -- The previous ServerWorks ServerSet III/HE has now been upgraded and improved in the form of the ServerWorks GC-LE chipset (see: http://www.serverworks.com/products/GCLE.html ) I would also suggest one of the Syskonnect gig cards, rather than the 3Com or Netgear gig cards cards. In some configurations we've seen a 300Mbps increase in throughput over the local area (relative to what an Intel gig card delivered) simply by swapping in a Syskonnect SK-9843. Of course, the real killer is still that the path MTU across most of the world is still abysmally small, typically 1500 octets. If folks really want to routinely go fast, they need to be working toward getting 9K frame sizes supported end to end (but that will be tremendously hard/impossible to make happen across the generic Internet).

VM It used to be that from our servers to my cable modem at VM home, it was Exodus - Teleglobe - Rogers. Now, after a VM massive round of depeering, it's Exodus - CW - Sprint - VM Teleglobe - Rogers. It's like that with pretty much VM everything: you used to have some networks who peered VM directly with Exodus, now traffic to them goes through CW VM and UUnet first, etc. The question is how it affects the bottom line. I have a client who used to colo at Exodus. After being quoted in excess of $1500 to set up BGP (!), refusal to cross-connect, and seeing the effects of the depeering, they bailed, and asked us to help build a network the right way so that they can _compete_ with Exodus. I doubt this is an isolated incident. What goes around comes around. As much as I'll whine about the stupidity of excessive depeering, my capitalist side loves it... it's much easier to set up a network with routes far superior than those who decide to force traffic the long way.

Most of what we know of as commercial computer's cannot generate more than 70% to 80% capacity on whatever network they are on because of driver overhead and OS latency etc etc etc. It was funny, but I remember testing FDDI on a UnixWARE based platform and watching the driver suck 79% of the system into the floor. Btw, if you've got a bit of time on your hands, the Click router components have some extremely-low-overhead drivers (for specific ethernet cards under Linux). Good Point. They can generate traffic at pretty impressive rates. They used them for testing DOS traffic for a while. http://pdos.lcs.mit.edu/click/ Still there are very few parametric engines that will generate more than 100Mb/S traffic - continuously. (Most of the driver overhead you see is interrupt latency; Depends on which OS you are running, and what encapsulation or other packaging/unpackaging is done in the Driver also accounts for a substantial amount of the compute model. If those services are done mostly in HW then the systems I have played with will give you up to about 80% capacity. And on ethernet that is not Collision-Free (i.e.run as full duplex), then you have to deal with the line characteristics so with both engines competing to flood the net you may actually get less than 80% total performance... click uses an optimized polling style to really cram things through). Also, the new FreeBSD polling patches should make it so you can get more throughput from your drivers when doing tests. I understand there are similar things for Linux.

(Nasdaq: WCOM, MCIT) today announced it intends to restate its financial statements for 2001 and the first quarter of 2002. As a result of an internal audit of the company's capital expenditure accounting, it was determined that certain transfers from line cost expenses to capital accounts during this period were not made in accordance with generally accepted accounting principles (GAAP). The amount of these transfers was $3.055 billion for 2001 and $797 million for first quarter 2002. Without these transfers, the company's reported EBITDA would be reduced to $6.339 billion for 2001 and $1.368 billion for first quarter 2002, and the company would have reported a net loss for 2001 and for the first quarter of 2002. The company promptly notified its recently engaged external auditors, KPMG LLP, and has asked KPMG to undertake a comprehensive audit of the company's financial statements for 2001 and 2002. The company also notified Andersen LLP, which had audited the company's financial statements for 2001 and reviewed such statements for first quarter 2002, promptly upon discovering these transfers. On June 24, 2002, Andersen advised WorldCom that in light of the inappropriate transfers of line costs, Andersen's audit report on the company's financial statements for 2001 and Andersen's review of the company's financial statements for the first quarter of 2002 could not be relied upon. The company will issue unaudited financial statements for 2001 and for the first quarter of 2002 as soon as practicable. When an audit is completed, the company will provide new audited financial statements for all required periods. Also, WorldCom is reviewing its financial guidance. The company has terminated Scott Sullivan as chief financial officer and secretary. The company has accepted the resignation of David Myers as senior vice president and controller. WorldCom has notified the Securities and Exchange Commission (SEC) of these events. The Audit Committee of the Board of Directors has retained William R. McLucas, of the law firm of Wilmer, Cutler Pickering, former Chief of the Enforcement Division of the SEC, to conduct an independent investigation of the matter. This evening, WorldCom also notified its lead bank lenders of these events. The expected restatement of operating results for 2001 and 2002 is not expected to have an impact on the Company's cash position and will not affect WorldCom's customers or services. WorldCom has no debt maturing during the next two quarters. Our senior management team is shocked by these discoveries, said John Sidgmore, appointed WorldCom CEO on April 29, 2002. We are committed to operating WorldCom in accordance with the highest ethical standards. I want to assure our customers and employees that the company remains viable and committed to a long-term future. Our services are in no way affected by this matter, and our dedication to meeting customer needs remains unwavering, added Sidgmore. I have made a commitment to driving fundamental change at WorldCom, and this matter will not deter the new management team from fulfilling our plans. Actions to Improve Liquidity and Operational Performance As Sidgmore previously announced, WorldCom will continue its efforts to restructure the company to better position itself for future growth. These efforts include: Cutting capital expenditures significantly in 2002. We intend 2003 capital expenditures will be $2.1 billion on an annual basis. Downsizing our workforce by 17,000, beginning this Friday, which is expected to save $900 million on an annual basis. This downsizing is primarily composed of discontinued operations, operations technology functions, attrition and contractor terminations. Selling a series of non-core businesses, including exiting the wireless resale business, which alone will save $700 million annually. The

If the MEDs are the same for both routes, the IGP metric for each BGP next-hop is likely making the decision. http://www.nanog.org/mtg-9811/ppt/avi/tsld010.htm Those are the criteria, in order, which BGP uses to make its decision. I am assuming synchronization, route to next hop, and router-local decisions (IBGP vs EBGP, weight) are non-issues in this scenario. Since localpref would be set internally, and AS path is the same (as I would assume origin code is), that leaves the MED as the first criterion, followed by shortest next-hop metric (IGP metric, typically). -c

RE: Big meetings should never be held at noon!
Jane, Couldn't you just use a full BGP feed from a provider and configure your inbound route-map/policy with the necessary parameters to obtain the part of the BGP table that you want? Or if this is just to populate something in a lab with a specific set of BGP info, you could obtain a copy of the table from someplace like route-views and load up the lab router or MRT (or equiv) in the lab and massage the table data within the lab. If this is for a customer/production router, I suppose you could coordinate with the upstream provider to do something similar with their outbound route-map/policy so that you only get a partial table. ___ Wayne Gustavus, CCIE #7426 Operations Engineering Verizon Internet Services ___ -Original Message- From: Pawlukiewicz Jane [mailto:[EMAIL PROTECTED]] Sent: Wednesday, June 26, 2002 1:54 PM To: [EMAIL PROTECTED] Subject: Big meetings should never be held at noon!

RE: how is cold-potato done?
Ultimately there won't be any ties, since BGP will eventually have to select a best path. If necessary, the decision will come down to RID. If the metrics really are the same then theoretically it doesn't matter which path it takes. If it does matter, you will have to modify your policy to make a decision based on some other criteria that you are also influencing via policy. ___ Wayne Gustavus, CCIE #7426 Operations Engineering Verizon Internet Services ___ -Original Message- From: Ralph Doncaster [mailto:[EMAIL PROTECTED]] Sent: Wednesday, June 26, 2002 2:08 PM To: Jared Mauch Cc: [EMAIL PROTECTED] Subject: Re: how is cold-potato done?

Re: how is cold-potato done?
Shortest-exit is the default because of the BGP decision process. This tends to favor heavy-content providers because the bulk of the data travels shorter distances out of the AS sending content to the AS receiving the content to their eyeballs. Shortest-exit is caused by IGP metrics (which shouldn't ever be the same for two paths, unless you actually want that to happen). IGP metrics are generally set by length of fiber paths or delay values. Provider backbones set these manually with ISIS or OSPF costs. There are many ways to do best-exit. People are always coming up with strange ways to do routing (ToS routing, MPLS-TE, DS-TE), and they can sometimes apply these techniques to best-exit. For those looking for something simple and standard, the two ways were made known in the first email - outbound MED's and delay-based routing from `traceroute' information. There are quite a few problems with this as well, documented in many various papers on the matter e.g.: http://www.ietf.org/internet-drafts/draft-ietf-idr-route-oscillation-01.txt For MED's, Avi spoke to the methods used in the following talks: http://www.nanog.org/mtg-9901/ppt/bgp102/index.htm http://www.nanog.org/mtg-9811/ppt/avi/index.htm One thing Avi mentioned here, I never quite understood.. http://www.nanog.org/mtg-9811/ppt/avi/sld031.htm He says set MED's in one direction only, but he doesn't say which direction or why. As to solving the aggregation problem making outbound MED's insignficant, there is some work trying to be solved using Communities (NO-PEER, supercommunities, redistribution, cost communities, link-bw, et al). Some of which is believed (and probably rightly so) to be overcomplicated and possibly even oscillatory just like the other methods. I enjoy the simple approach that RFC 3272 takes (surprisingly simple Inter-Domain traffic engineering coming from the super complex Intra-Domain TE based on MPLS/etc that the authors recommend). They have some suggestions on setting local_pref and inbound MED's that I found to be very clueful. http://www.ietf.org/rfc/rfc3272.txt (Section 7.0) Inter-domain TE is inherently more difficult than intra-domain TE under the current Internet architecture. The reasons for this are both technical and administrative. So maybe best practice today for doing best-exit is simply having the technical data (communities, tags, traffic, etc) and talking directly with the administrators of your peer-AS to find a solution (or reading their minds without their data, or inferring it, or guessing). I guess the final question is -- why is anyone concerned about best-exit at all? Doesn't shortest-exit still get the traffic there? I'm willing to bet there are a lot of different answers to all these questions. -dre On Wed, Jun 26, 2002 at 02:35:55PM -0400, Leo Bicknell wrote: In a message written on Wed, Jun 26, 2002 at 01:52:08PM -0400, Ralph Doncaster wrote: If I peer with network X in cities A and B, and receive the same route in Wow, I'm amazed at the wrong answers here.

RE: ARIN IP allocation policy, ip vs. name website hosting
Hello Matthew, I recall reading that ARIN was preferring the use of hostname based virtual websites over IP based, however I can't find that wording on ARIN's site. In early 2001 a policy proposal regarding name-based web hosting gained consensus at an ARIN public policy meeting and resulted in the ratification of a new policy. In July of 2001 this policy was reviewed and overturned. ARIN does not currently have a policy that requires the use of hostname based virtual web hosting.

RE: Sprint peering policy
Alex, *I* can't make any claims, since that would be making a forward-looking statement, y'know... and after today's WorldCom events, I can hardly say that trusting analysts is a good thing, but if you take the time to do some research on ALGX, you'll probably see things like: consistency in meeting Wall St. expectations, a stong management team (after all, they *did* build MFS), and a conservative balance sheet. We're talking about some experienced, reputable good ol' boys who know enough only acquire profitable businesses for pennies on the dollar, and only build from success-based capital. If you take a good, hard look at the company as a whole, you'll see a company that has yet to deviate from its original plan, regardless of economic climate, and will tell you is still on target for profitability. These are all things I've learned from my own due dilligence via research on the web, and I'm sure you'll find the same. I know. It is going to be a localy company to add to WCOM, MFNXQ, ADELA, Q and others like that for exact reasons that you have listed. Cheers, Alex

IMHO, IM is a security risk and I am establishing a company standard where users behind the firewall are prohibited from using IM, IRC, and peer-to-peer file sharing programs. My opinion is that these types of programs contribute more to lack of productivity than to real problem solving. So my question for the group is, do chat programs (IM, IRC, yahoo) serve a substantial network support purpose or are they more of a distraction, allowing staff to communicate with friends, relatives, drifters, interlopers on company time? Do such things contribute to time not spent on purely company-focused efforts? Undoubtedly. Is such lost time offset by happy employees? I think so. Additionally, I know I for one have picked up at _least_ as much useful knowledge from idling among really smart folk on IRC as I have from any other public forum, mailing lists included. IRC can be an _excellent_ forum for education. Like any tool, the utility or hazard mainly depends on those using it. I'm not sure the time you will gain by flatly denying use of these common tools to be worth the ill will garnered.

We're a fairly small ISP; we currently have a /24, a /25, and a /28 allocated piecemeal from our upstream's two /19s. (Upstream is Viawest). Now that we've rolled out DSL we're needing a bit more space - based on current trends about 200 addresses over the next 6-12 months. Viawest has just told me that their policy is that customers who go over a /23 worth of address space must request further space directly from ARIN. In other words, we're supposed to call ARIN up and get a private /24 for this. We're not multi-homed; we have absolutely no need for a private /24 instead of a chunk of Viawest's existing space. We're not growing rapidly and it's very unlikely we'll more than 4 class C's worth of address space in the next 4 years. Questions: can we actually qualify for a /24 from ARIN? Will all NSPs accept a private /24 announced from Viawest without us having to track down each NSP and negotiate with them? Will the ARIN fee be $2500? Is refusing to provide small blocks out of their own address space a common practise for NSPs? The private /24 issue makes me mildly grouchy due to the whole global routing table size issue, but the $2500/year makes me REALLY grouchy, especially as that same /24 would cost our upstream about $40/year.

What they (Viawest) are saying you is that they are too small to serve you. Your domain record says you are in Denver, so I'm guessing you must have many choices for ISP. Find another, have them toss a /22 or more your way, and put Viawest behind you. -mark
