The Choice: IPv4 Exhaustion or Transition to IPv6
by JORDI PALET MARTINEZ 02 Jul '07

02 Jul '07

Hi all, I've published a document trying to analyze the IPv4 exhaustion problem and what is ahead of us, considering among others, changes in policies. http://www.ipv6tf.org/index.php?page=news/newsroom&id=3004 I guess this could be useful in order to understand possible implications of modifying existing policies, or setting up new ones, or even just to create some debate about those changes. The document was completed last April, but didn't had the time to tidy up until a few days ago.

Half day will be presented by a single Instructor, or a Full day tutorial may be presented by a team of two instructors working together. Tutorial Instructors are encouraged to also sign up to be a Speaker in the Technical Conference Program as well. You can sign up to give a tutorial and/or conference session presentation by following the instructions at the end of this message for signing up as a speaker or instructor. Tutorial topics which have successful in the past, or have been requested for this year are: - Network security, IPSec, Auditing/Forensics, DDoS Mitigation, VoIP Security - Address planning, conservation, responsibility and migration to IPv6 - High performance IP backbone routing and management - BGP MultiHoming - MPLS - IPv6 implementation - Network planning, management and traffic engineering - Internet exchanges, construction, peering and collocation - Operations, NOC, Helpdesk and other support aspects - BIND, DNSSEC, Split Horizon DNS, and Reverse and multilingual DNS - Broadband first/last mile access technologies - Mobile and wireless technologies - Content, Applications, streaming and multimedia infrastructure - VoIP, Unified messaging, scaling e-mail infrastructure, Asterisk, etc. - Hosted Essential Services (mail, DNS, etc), Server scaling, Open source The program committee will consider proposals for tutorials in any of these areas, and also in new areas. There will be two days of Tutorials. Tutorials last 1/2 day or a full day and can cater to beginner through to advanced audiences. Tutorial days are typically split into four 1.5 hour sessions. If you have an idea for a tutorial subject that is not listed, please feel free to submit it to us. TECHNICAL CONFERENCE SESSIONS ----------------------------- The Main Conference Program for 2008 will be made up of two days, with three streams each day. In addition there will be a colocated meetings of the Asian Broadband Summit and the Asia Pacific IPv6 Task Force. The Asia Pacific Top Level Domain (APTLD) will also hold their members meetings during APRICOT. Each stream will consist of four 1.5 hour sessions, with each having three or four presentations. This allows 20-30mins per presenter. Presentation longer then 25 minutes should be submitted as tutorials. Sessions are chaired by persons of appropriate expertise in the subject matter of the session and will include ample time for questions from the audience. Successful presentations from past APRICOTs have covered topics relevant to current operational deployments or new technologies not yet in wide deployment. Proposals for conference presentations are invited for topics fitting into the six streams outlined above. If you would like to give a presentation at one or more of the sessions, follow the instructions at the end of this message for signing up as a speaker or instructor. PEERING ---------- If you are an ISP or Content Provider that can share some experiences peering in Asia and abroad, please consider contributing an abstract for the Peering track in the Inter Provider Relationship stream. Given that this track has been highly popular, with enough support this will evolve into the Asian version of the Global Peering Forum. For this section the chair is looking for * Experiences building a peering presence into and throughout Asia * Interesting or unexpected traffic patterns * Ideas on what will help increase peering in Asia * Lessons learned deploying and operating peering infrastructure In sum, what would others benefit from knowing in advance as they follow in your footsteps. If you have some operations experiences to share, please submit it online following the procedure outlined below. Alternatively, send a note to bill.norton(a)gmail.com with the subject: "APRICOT 2008 Peering Track Idea". LIGHTNING TALKS ---------------- After the successful introductions of Lightning talks at APRICOT 2007, we will continue with it. Call for papers for Lightning talks will be made during APRICOT, and will be limited to participants of the conference. CFP SUBMISSION -------------- When considering a presentation or tutorial, remember that the APRICOT audience is mainly comprised of technical network operators and engineers with a wide range of experience levels from beginners to multi-year experience. There is a strong orientation to offer core skills and basic knowledge in the tutorials and to address issues relevant to the day-to-day operations of ISPs and network operators over the next 12 - 18 months in the conference sessions. The deadline for submissions is 30 September, 2007. Draft slides for both tutorials and conference sessions MUST be provided with CfP submissions. Final slides are to be provided by 15 January, 2008. While the majority of speaking slots will be submitted by 30 September 2007, a limited number of slots may be available for presentations that are exceptionally timely, important, or of critical operational importance. Please submit online at http://submission.apricot.net/paper/user/login.php?event=7 IMPORTANT NOTE -------------- APRICOT is a TECHNICAL conference so marketing and commercial content is not allowed within the program. The program committee is charged with maintaining the technical standard of APRICOT, and will therefore not accept inappropriate materials. It is expected that the presenter be a technical person and not a sales or marketing person. The audience is extremely technical and expects that the speakers are themselves very knowledgeable. All sessions provide time for questions, so presenters should expect technical questions and be prepared to deliver insightful and technically deep responses. FUNDING AND SUPPORT ------------------- 'APRICOT is a not-for-profit event that tries to keep the cost to attendees low so we are unable to pay the travel costs of speakers. Speakers from developing countries may be eligible for the APRICOT Fellowship Program which provides basic assistance to successful fellows to cover local living and registration expenses associated with attending the conference.' More information on the APRICOT Fellowship program can be found at the APRICOT 2008 website at http://www.apricot2008.net/ Accepted tutorial speakers will receive complimentary registration to both the tutorials and conference. SUBMISSION DETAILS ------------------ If you would like to be considered as a tutorial instructor, session speaker, or a convener of a BOF, please fill in the form at http://submission.apricot.net/ More information on the conference is available at http://www.apricot2008.net/ Thanks.

Cable-Tying with Waxed Twine
by Dan Mahoney, System Admin 30 Jun '07

30 Jun '07

Hey all, This seems a wee bit off topic, but definitely relates to network operations (somewhere below layer 1) and I can't think of a better place to ask. Upon leaving a router at telx and asking one of their techs to plug in the equipment for me, I came back to find all my cat5 cables neatly tied with some sort of waxed twine, using an interesting looping knot pattern that repeated every six inches or so using a single piece of string. For some reason, I found this trick really cool. I have tried googling for the method, (it's apparently standard, I've seen it in play elsewhere), and for the type of twine, but had little luck. I was wondering if any of the gurus out there would care to share what this knot-pattern is actually called, and/or if there's a (illustrated) howto somewhere? -Dan "Tired of getting scratched up by jagged cable ties" Mahoney -- --------Dan Mahoney-------- Techie, Sysadmin, WebGeek Gushi on efnet/undernet IRC ICQ: 13735144 AIM: LarpGM Site: http://www.gushi.org ---------------------------
