NANOG 42 Peering BOF XVII and APRICOT 2008 Peering Forum
by William B. Norton 11 Jan '08

11 Jan '08

Hi all - In about a month (starting Feb 17 specifically) there will be two back-to-back events specifically for network engineers and peering coordinators; at NANOG 42, Feb 19, we will have the 17th Peering BOF (http://www.nanog.org/mtg-0802/agenda.html) and the following week, at APRICOT 2008, Feb 25-26 there will be an AP Peering Forum (http://www.apricot2008.net/P09.html#t1) held in Taipei, Taiwan. I need volunteer speakers and topics for both of these, and if you are a network operations person, I bet you might have a story to share with the group ! I'm looking for stories of interest to the peering community, such as: What processes did you use to transition an upgrade to your network? What worked well and what did not? What did you wish you knew when you built into and throughout different regions or countries? How did you select these locations (transport, transit, peering costs? attractive market? customers?) What was unexpected, or what lessons learned would you share with folks who would walk in your footprints? (technical, business, ops, legal, etc.) How did you decide which countries to build into, and what were the hidden costs and snafus? Basically, anything you would like to hear or would like to have heard would be appropriate. I have 45 minutes left to fill in the NANOG Peering BOF and a lot of time left for the APRICOT Peering Forum. If you can share your experiences on these or other topics at either or both of these forums, please send me a note ASAP. Also, we will once again have the Peering Personals at the Peering BOF and at the APRICOT Peering Forum, providing a chance for peering coordinators to introduce themselves to the group, describe their network and the types of networks they would like to peer with. If you would like to stand up and introduce yourself to the group, please fill out and send me the Peering Personals Form below. Thanks - William B. Norton for the Fabulous Internet Traveling Circus PS - Here is the URL to my working copy of the NANOG 42 Peering BOF Agenda - send me an email with additions, corrections, comments, etc. If you would like to edit the agenda that can be arranged as well: http://docs.google.com/Doc?docid=dddj3pds_41f5cwctng&hl=en -------------------------------- Peering Personals Form ------------------------- Peering Coordinator 1) Name: _____ 2) email: _____ Company: 3) AS#: ______ 4) Peering Locations Now: ______ 5) Peering Locations (Planned or future): _____ 6) Transit traffic volume: ___ Mbps or Gbps 7) Traffic mostly outbound or inbound? ______ 8) What are you looking for in a peer? ______ (I'll ask this when you stand up to introduce yourself) 9) Why should folks want to peer with you? _____ (I'll ask this also when you stand up) This information will appear on the screen behind you as you introduce yourself to the Peering BOF community. That way they can jot down whatever info they need and can put a face to a company, and hopefully have a discussion about peering at the break. We have found this to be a valuable way to facilitate the interaction between people who may not have an easier way to meet each other while at NANOG or APRICOT. I will allocate spots for 5 or so peering personals. ---------------------------- /Peering Personal Form ------------------------------ -- //------------------------------------------------ // William B.

Fwd: UKNOF9: London, Monday 14th January - Agenda
by Andy Davidson 11 Jan '08

11 Jan '08

Hi, For the small number of us in the UK who have not seen this notification, the ninth UKNOF meeting is going to happen on Monday - there are some spaces left, so why not visit and meet some of your counterparts in the industry ? For those who are not local, remote participation is available by following the 'Webcast' link on http://www.uknof.org.uk/uknof9/ The listed times are in GMT, so the kick off would be 5am on the east coast. I hope to see some of you there. Best wishes Andy Begin forwarded message: > From: Keith Mitchell <keith(a)uknof.org.uk> > Date: 4 January 2008 20:22:10 GMT > To: uknof(a)uknof.org.uk > Subject: [uknof] UKNOF9: London, Monday 14th January - Agenda > Reply-To: uknof(a)uknof.org.uk > > Happy New Year.

Microsoft's Black Tuesday bandwidth impact?
by Frank Bulk 10 Jan '08

10 Jan '08

Every month I look at my upstream bandwidth graphs and I see no blip in the hours before 3 am on Microsoft's Black Tuesday. I would think that with the thousands of PCs out on our network downloading updates around that time that I would see *something*. I know every Black Tuesday I see my three PC's blinking a logon screen. Are MSFT's monthly updates really a non-event in regards to internet bandwidth? Frank

Re: Using x.x.x.0 and x.x.x.255 host addresses in supernets.
by Joshman at joshman dot com 10 Jan '08

It's funny that you ask. The organization I am working with that spawned this question in the first place has /22 dhcp pools at multiple sites-- for both VoIP and workstations. "For future growth..." they said. Why the decision was made not to scale with additional VLANs at a later date is beyond me(or my pay-grade). They thought it was preposterous that I suggested that there are a lot of providers/networks that exclude .0 and .255 host addresses from DHCP pools/etc, and do not use them as a matter of convention/best practice. I casually suggested this fact and was subsequently chided. The reason I posed this question in the first place, is that in my experience, most organizations I have worked with do not use them. It appears from the thread that there are some legitimate concerns with using .0 and .255 hosts, even though many consider these concerns dated or legacy. Thanks to everyone for their opinions.

Date: Tue, 8 Jan 2008 05:45:36 -0800 (PST) Hello all, As a general rule, is it best practice to assign x.x.x.0 and x.x.x.255 as host addresses on /23 and larger? I realize that technically they are valid addresses, but does anyone assign a node or server which is a member of a /22 with a x.x.x.0 and x.x.x.255? Is it just a manner of preference on whether or not to use them, or are there functional reasons you shouldn't; either with rfc 1918 addresses or public addresses.

RE: ISPs slowing P2P traffic...

I'm not aware of any modern cable modems that operate at 10 Mbps. Not that they couldn't set it at that speed, but AFAIK, they're all 10/100 ports.
