This is a crock. It is but nobody worries about that, we trust route servers at IX carrying way more traffic than most of these access circuits. brandon

Programmable SFP+ Transcievers
by Colton Conor 26 Jan '16

26 Jan '16

What options are out there for re-programmable SFP and SFP+ transceivers? So far I have found both https://www.flexoptix.net/en/flexbox-v3-transceiver-programmer.html and http://solid-optics.com/tools/multi-fiber-tool/so-multi-fiber-tool-id1768.h… Is there anything else out there? Any opinions on these two companies? I believe they both require you to use their SFPs in order to program them, but I could be wrong.

The general case doesn't care about your network, it assumes you'd engineer that appropriately for the criticality and do something different/better if you need to. brandon

OT: ID/RFC formatting
by Jay R. Ashworth 25 Jan '16

25 Jan '16

I know we have to have a few people on here who've written technical RFCs (as opposed to 1 April ones like my RFC 2100)... Any tips on 1) how to do inline boldface and 2) what to do with ASCIIart illustrations that are too wide for the page? I'm using Stefan Santteson's nroffEdit (since I'm presently stuck on Windows), but it doesn't seem to like .B/.R or \fB / \fP for the former, and on the latter point, it's simple unclear how I should approach the thing (a four-column time-sequence diagram of a network transaction, similar to that of the four-point SIP call.

Call for presentations RIPE 72
by Benno Overeinder 25 Jan '16

25 Jan '16

Dear colleagues, Please find the CFP for RIPE 72 below or at https://ripe72.ripe.net/submit-topic/cfp/. The deadline for submissions is 13 March 2016. Please also note that speakers do not receive any extra reduction or funding towards the meeting fee at the RIPE Meetings. Kind regards, Benno Overeinder RIPE PC Chair https://www.ripe.net/participate/meetings/ripe-meetings/pc -------------------->>><<<-------------------- Call for Presentations A RIPE Meeting is an open event where Internet Service Providers, network operators and other interested parties get together. Although the meeting is mostly technical, it is also a chance for people to meet and network with others in their field. RIPE 72 will take place from 23-27 May 2016 in Copenhagen, Denmark. The RIPE Programme Committee (PC) is now seeking content proposals from the RIPE community for the plenary sessions, BoFs (Birds of a Feather sessions), panels, workshops, tutorials and lightning talks at RIPE 72. See the full descriptions of the different presentation formats, https://ripe72.ripe.net/submit-topic/presentation-formats/. Proposals for plenary sessions, BoFs, panels, workshops and tutorials must be submitted for full consideration no later than 13 March 2016. Proposals submitted after this date will be considered depending on the remaining available space in the programme. The PC is looking for presentations covering topics of network engineering and operations, including but not limited to: - IPv6 deployment - Managing IPv4 scarcity in operations - Commercial transactions of IPv4 addresses - Data centre technologies - Network and DNS operations - Internet governance and regulatory practices - Network and routing security - Content delivery - Internet peering and mobile data exchange Submissions RIPE Meeting attendees are quite sensitive to keeping presentations non-commercial, and product marketing talks are strongly discouraged. Repeated audience feedback shows that the most successful talks focus on operational experience, research results, or case studies. For example, presenters wishing to describe a commercial solution should focus on the underlying technology and not attempt a product demonstration. Presenters should indicate how much time they will require. In general, the time allocated for the different presentation formats is as follows: - Plenary presentations: 20-25 minutes presentation with 5-10 minutes discussion - Tutorials: up to two hours (Monday morning) - Workshops: one hour (during evening sessions) to two hours (Monday morning) - BoFs: approximately one hour - Lightning talks: 10 minutes The following general requirements apply: - Proposals must be submitted using the meeting submission system, https://ripe72.ripe.net/submit-topic/submission-form/. - Lightning talks should also be submitted using the meeting submission system (https://ripe72.ripe.net/submit-topic/submission-form/) and can be submitted any time up to and including the meeting week. The allocation of lightning talks will be announced on short notice---in some cases on the same day but often one day prior to the time slot allocated. - Presenters who propose a panel or BoF are encouraged to include speakers from several (perhaps even competing) companies and/or a neutral facilitator. - All presentation proposals will only be considered by the PC if they contain at least draft presentation slides (slides may be updated later on). For panels, proposals must contain a clear description, as well as the names of invited panellists, presenters and moderators. - Due to potential technical issues, presenters/panellists should be physically present at the RIPE Meeting. If you have any questions or requests concerning content submissions, please email pc [at] ripe [dot] net. -- Benno J. Overeinder NLnet Labs http://www.nlnetlabs.nl/

Equinix 350 E. Cermak
by Mike Hammett 25 Jan '16

25 Jan '16

Do any of you have excess space within Equinix at 350 E. Cermak? It needs to be both of those due to the number of cross connects to other players within Equinix 350 E. Cermak. Equinix direct is pricing full cabs at a ridiculous price. Given that we need 1/4 cab or less, it's hard to justify the full thing at those rates. Every time we think we've got someone lined up, their space is actually Equinix out in Elk Grove or 350 E. Cermak, but in TelX or Steadfast instead. I see a lot of partially filled cabinets when I walk through to our existing space. Come on now.... ;-) ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com

Cisco CMTS SNMP OID's
by Lorell Hathcock 24 Jan '16

24 Jan '16

All: Does anyone out there have some valuable OID's for a Cisco CMTS? The ones I am looking for are: Signal to Noise per upstream channel Cable Modem counts of all kinds connected / online ranging offline I opened a ticket through Cisco's help desk. I have a SmartNET contract for the unit, but they were not very helpful. The OIDs they suggested did not yield any useful data. ("0" when I know there are CMs connected, etc). Thanks in advance.
