Verizon PSTN continued
by David Hubbard 08 Nov '06

08 Nov '06

The thread yesterday didn't seem to get into much detail; I'm wondering if anyone knows more about what is going on with Verizon? Our PSTN service with XO seems to be affected again by what XO claims is a Verizon problem but they wouldn't elaborate on why they feel that to be the case; I was just amazed to even get someone on the phone at XO since normally they are unreachable. I am inclined to partially believe them since I've found other numbers that I know to be with other carriers that are not working. XO claimed this was at least a regional issue of Verizon's that is affecting multiple carriers. David

Verizon PSTN issues?
by Jay Hennigan 07 Nov '06

07 Nov '06

I'll try not to be as vague as the last person... We are in Verizon (former GTE) territory in Santa Barbara, CA, LATA 740. For much of the day we have had complaints of reorder from dialup users as well as reports of reorder from people trying to call us from out of the area. I saw a note on another forum that claimed that Verizon was having "nationwide issues" but gave no other detail. Verizon rep hasn't returned voicemail, l-o-n-g hold time on repair, gave up.

Call for Presentations - NANOG 39 - Toronto
by Steve Feldman 06 Nov '06

06 Nov '06

The North American Network Operators' Group (NANOG) will hold its 39th meeting February 4-7, 2007, in Toronto, Canada. The meeting will be co-hosted by the Toronto Internet Exchange and Teleglobe, a VSNL International company. NANOG conferences provide a forum for information exchange among network operators, engineers, and researchers. Meetings are held three times each year, and include panels, presentations, tutorial sessions, and BOFs. NANOG solicits presentations highlighting issues relating to technology already deployed or soon to be deployed in the Internet. The NANOG community is invited to attend and participate in this forum, which offers numerous opportunities to share ideas, explore research and development, and interact with leaders in this important field of network operations. Vendors are encouraged to work with operators to present deployment experiences with the vendor's products and interoperability. General Session =============== The community is invited to develop panel sessions or present talks on topics relevant to the NANOG community, including: Network Operations Present-day operational case studies Everyday life in the NOC and tools of interest Exchange point technologies and implementation Peering/colocation coordination issues Content provider issues Security attacks/mitigation, tools, and analysis State of OAM tools for IP and MPLS networks Disaster recovery and planning Deployment Experience Mergers and their impact on interconnected networks Alternative and emerging last-mile technologies (metro/rural, broadband, radio, optical, etc.) VoIP deployment, architecture, peering, and interconnect Anycast IPTV Large-scale wireless Fiber and wavelength use by enterprises Research, Policy, and New Technology Approaches to securing the global routing system (e.g., s*BGP and/or other tools) Routing system scalability Capacity planning standards and tools Inter-provider MPLS/QoS/PCE RIR policy (e.g., implications of HD ratio) Active standards organizations and areas of interest IPv6: economics, deployments, and adoption rates Approaches to IPv6 scalability, e.g., Shim6 Panels ====== Panel selection will be based on the importance, originality, focus and timeliness of the topic; expertise of proposed panelists; as well as the potential for informative and controversial discussion. The panel leader should provide an abstract describing the panel theme, list of panelists, and an outline of how the panel will be organized. After acceptance, the panel leader will be given the option to invite panel authors to submit their presentations to the NANOG Program Committee for review. Until then authors should not submit their individual presentations for the panel. Lightning Talks =============== A lightning talk is a very short presentation or speech by any attendee on any topic relevant to the NANOG audience. These are limited to ten minutes; this will be strictly enforced. If you have a topic that's timely, interesting, or even a crackpot idea you want to share, we encourage you to consider presenting it. Signups for lightning talks will be accepted during the NANOG meeting. Research Forum ============== Researchers are invited to present short (10-minute) summaries of their work for operator feedback. Topics include routing, network performance, statistical measurement and analysis, and protocol development and implementation. Studies presented may be works in progress. Researchers from academia, government, and industry are encouraged to present. Tutorials ========= Proposals are also invited for tutorial sessions from the introductory through advanced level on all related topics, including: Disaster Recovery Planning Troubleshooting BGP Best Practices for Determining Traffic Matrices Options for Blackhole and Discard Routing BGP/MPLS Layer 3 VPNs BOFs ==== BOFs (Birds of a Feather sessions) are 90-minute informal sessions on topics which are of interest to a portion of the NANOG community. A typical BOF session includes some presentations, but usually is focused on community discussion and interaction. Frequent BOF topics include: Peering ISP Security Tools Registration Fee Waivers ======================== The meeting registration fee will be waived as follows: - General session talk: one speaker - General session panel: one moderator and all panelists - Research forum talk: one speaker - Tutorial: one instructor - BOF: one moderator How to Present ============== The primary speaker, moderator, or author should submit presentation information and an abstract online at: http://www.nanogpc.org Once you have done this, the you will receive instructions for submitting your draft slides. See http://www.nanog.org/presentations.html for complete submission guidelines. All submissions must include: Author's name(s) Preferred contact email address Submission category (General Session, Panel, Tutorial, Research Forum, or BOF) Presentation title Abstract Slides (attachment or URL), in PDF (preferred) or Powerpoint format (Slides are optional for BOFs.) You may instead submit the presentation information and draft slides in email to nanog-support(a)nanog.org. The deadline for proposals is Thursday, December 7, 2006. A limited number of slots may be available after that date for topics that are exceptionally timely, important, or critical to the operation of the Internet. Submissions will be reviewed by the NANOG Program Committee, and presenters will be notified of acceptance by December 17. Final drafts of presentation slides are due for review on January 19, and final versions for posting are due on January 26.

Probably off-topic but I (Mozilla) am in a bind - I need a Cisco GLC-SX-MM (or one that works in a Cisco). I have some on order but they're on order. In Mountain View, if you can help. - mz -- matthew zeier | Network Engineer | Mozilla Corp. | (650)903-0800 x219

my problem or AT&T's?
by mliotta＠r337.com 06 Nov '06

06 Nov '06

We are AS35985 and provide transit for AS36845. Currently, AS7018 is able to route to us (AS35985), but not our customer (AS36845). I have checked every looking glass and traceroute site I can think of. Every network I have tried has a route through us to AS36845 except AS7018. I of course checked AT&T's looking glass and didn't find a route to our customer. I would expect AT&T to have a route to our customer via AS1299, but they don't. Any thoughts? -Matt

Re: CWDM equipment (current favorites) (fwd)

There's been some discussions more recently, such as (coauthored by yours truly): http://www.nanog.org/mtg-0606/pdf/lightning-talks/4-pilosov.pdf http://www.nanog.org/mtg-0610/presenter-pdfs/pilosov.pdf > Since then, I have actually touched some of the MRV product line > personally and found it (and their customer support)... less than ideal. > (not comparing to anyone else, and no one is really ideal). > > The bigger problem was that the devices seem to be less than intuitive, > but rock solid once they are working. (which is what everyone praised > them for). Passive CWDM gear is pretty much all created equal as far as intuitiveness in how to connect it (assuming gear is non-broken). You have muxes, you have SFPs/GBICs, and you plug GBIC output into the mux input. :) As far as the SFP/GBIC quality, I think MRV is very good. At one point, (maybe even still) Cisco OEM'd MRV gbics under their brand (and with attendant 1000% markup). You can also look at cubo and infineon optics, good quality at reasonable price. Be wary about chiwanese vendors - quality is questionable: high DOA rate, output light level and input sensitivity vary from one module to another. Pricewise, you might find that cubo isn't *that* much more expensive than chiwanese gear. Also, there's market (like, again, from yours truly) of the new-in-box MRV gear, which may also be an option. > We need to place a new order for some new fiber builds and were > considering some other vendors. Especially in the nx2.5G and nx10G (are > CWDM x-cievers even available in 10G yet?) range. Anyone have any new > favorites? 2.5G are only slightly more expensive than 1G - if you have OC48 gear that is SFP-capable, by all means, use that. 10G CWDM is *rumoured* to exist, but I don't think there are any production ones yet. Feel free to correct me. 10G is all DWDM, and so far very pricy.
