nanog 43 draft agenda posted
by Todd Underwood 10 Apr '08

10 Apr '08

<hat type="program committee" role="chair" scope="NANOG"> the astute (or obsessive) among you may have already noted that the nanog 43 draft agenda was recently posted at: http://nanog.org/mtg-0806/agenda.html the program committee is excited about both the content that has already been selected and how early we have been able to get this announcement out to the community. we have received feedback indicating that announcing most of the agenda early significantly improves attendees' ability to obtain travel approvals and make travel plans. so here you have it. two months out. there are a few slots left and a bunch of great content still in the submission queue, so expect a final agenda announcement within a couple of weeks. if you have not already booked your travel and hotel for nanog 43 in brooklyn, please consider doing so soon. hotel rooms are a steal for NYC (only $239!) and the city is beautiful in june. thanks very much to telx for subsidizing the rooms to meet the cost standards of the unusually frugal (even miserly) group that we are! this is really what makes this nanog in brooklyn possible. i want to thank the community for the outpouring of interesting submissions that we received--there was a lot of good content to choose from. i also want to thank the program committee members for all their hard work recruiting, shepherding and reviewing content. it's not easy being on the program committee and we have a great team of people working hard to produce this conference. we think you'll like it. hope see you in brooklyn. todd underwood </hat> -- _____________________________________________________________________ todd underwood +1 603 643 9300 x101 renesys corporation general manager babbledog todd(a)renesys.com http://www.renesys.com/blog http://babbledog.com/

RE: fiber switch for gig
by Andrew Staples 09 Apr '08

09 Apr '08

I was asked to summarize what I found. I only had two personal recommendations based on respondents use/experience, so I don't have much of a rating to give back to the list. However, I did do some research as follows. Some disclaimers/explanations: 1. Best Price = no gbics. Total Price = includes gbics @ $80/each (generic brand GBIC, not sure it they work in all models. I've not had problems using generic gbics in FC switches.ymmv) 2. Feature set is my personal subjective rating based on high-level features important to me. Your feature-set needs may be different. 3. Couldn't find RPS info on two switches. As an alternative, I like to use Tripplite Digital Power ATS PDUs for all my single-power-supply gear. 4. There may be additional costs for various feature sets. 5. Best pricing usually means used/refurbed gear with warranties. I've added the base list price (without gbics) if you like shiny new. 6. No warranties expressed or implied as to the accuracy/completeness of the info below (I didn't call each manufacturer to verify their documentation). If you can clarify any inaccuracies, send me a note off-list. 7. I couldn't verify if the Force10 needed gbics or not.two different documents gave conflicting information, so I assumed worst-case. 8. No particular ranking is imputed by the table. 9. Delete the email rather than complain about the html format.

Lots of 48 port gig switches have 2-4 fiber uplink ports, but this means daisy-chains instead of hub/spoke. Looking for a central switch for a star topography to home fiber runs that is cost effective and works. Considering: DLink DXS-3326GSR NetGear GSM7312 Foundry SX-FI12GM-4 Zyxel GS-4012F I realize not all these switches are IEEE 802.3ae, Clause 49 or IEEE 802.3aq capable.

I doubt we'll ever see the day when running gigabit across town becomes cost effective when compared to running gigabit to the other end of your server room/cage/whatever.

XO Support Contact?
by Matthew Evans 09 Apr '08

09 Apr '08

Hello everyone, I'm having an issue with a customer that XO Communications and I have in common who is seeing outrageous latency. I've tried to submit a request via the XO website, but it appears their automated form is broken. If an XO support rep can contact me off-list I'd appreciate it; or if anyone has a direct email contact for XO Business Support, please email me personally and I'll buy you a virtual beer.

"Does TCP Need an Overhaul?" (internetevolution, via slashdot)
by Paul Vixie 09 Apr '08

09 Apr '08

in <http://www.internetevolution.com/author.asp?section_id=499&doc_id=150113> larry roberts says: ..., last year a new alternative to using output queues, called "flow management" was introduced. This concept finally solves the TCP unfairness problem and leads to my answer: Fix the network, not TCP. ... What is really necessary is to detect just the flows that need to slow down, and selectively discard just one packet at the right time, but not more, per TCP cycle. Discarding too many will cause a flow to stall -- we see this when Web access takes forever. Flow management requires keeping information on each active flow, which currently is inexpensive and allows us to build an intelligent process that can precisely control the rate of every flow as needed to insure no overloads. Thus, there are now two options for network equipment: o Random discards from output queues bIntelligent rate control of every flow -- creates much TCP unfairness o Intelligent rate control of every flow -- eliminates most TCP unfairness ... i wouldn't want to get in an argument with somebody who was smart and savvy enough to invent packet switching during the year i entered kindergarden, but, somebody told me once that keeping information on every flow was *not* "inexpensive." should somebody tell dr. roberts? (i'd hate to think that everybody would have to buy roberts' (anagran's) Fast Flow Technology at every node of their network to make this work. that doesn't sound "inexpensive" to me.
