Inside plant 10G fiber specs?
by Jeff Kell 16 Mar '10

16 Mar '10

I am working up network specs for a new building, and trying to accomodate a 10G distribution from the start. The safe bet of running singlemode everywhere doesn't quite fit due to cost of the optics and the need for multimode for some other (non-network) devices anyway. We have a legacy 62.5u/MM campus, inside and out. The 100M to 1G transition led to some outside plant singlemode additions due to length restrictions on MM (even with conditioned LH optics), but the inside plant gig was fine with multimode (typically SH optics). 10G appears to break the inside 62.5u/MM fit, with the addition that there is no option of "LH over MM" for the little extra push beyond the SH limit that worked with 1G optics. Cisco's references give 10G SH over 62.5u/MM at 26m or 33m, depending on the "modal bandwidth" of the fiber. At those distances it is of little benefit except some limited vertical risers. 10G over 50u/MM looks better, depending on the "modal bandwidth" of the fiber (66m, 82m, 300m). So, a couple of questions... (1) Do you have a good vendor specification (or sample cables) for multistrand 50u/MM suitable for the 2000Mhz/km (300m) advertised reach? (2) Inter-operability issues with legacy equipment where we have always used 62.5? We have at least two alarm half-duplex loops over 62.5 that will have to "mate" with devices in this building... if I can avoid running both types MM that would be great. (3) Any other considerations or words of advice would be welcomed. Thanks in advance. Jeff

Hi I have questions about security I am using mozila to access gmail as https://mail.google.com/mail Why mozilla prompts me the alert box? "You have requested an encrypted page that contains some unencrypted information. Information that you see or enter on this page could easily be read by a third party." 1/ Can network software help to check? if yes. which software and how? 2/ How mozilla knows I have data not encrypted? 3/ ls https secured? If not. why it is PCI? Thank you Send instant messages to your online friends http://uk.messenger.yahoo.com

The massive deployments of FTTH around the globe (now tens of millions of end points per quarter) have been responsible for driving price points for singlemode optics down considerably, and it's only going to get a lot cheaper over time before bottoming out. Plan to the trajectory, not the history. OM3 & OM4 MMF will provide considerably greater reach than their forebears, but if you're looking to centralize servers and avoid myriad intermediate TRs and LAN rooms due to distance constrains along the way (cascading bottlenecks), then give singlemode a closer look. You may also want to give IEEE 10GE PON (ratified last year) some consideration, or <forsooth!> the ITU emerging variant of 10GPON for your desktop and lab areas, fwiw.

Avaya CNA/RouteScience masters
by Drew Weaver 14 Mar '10

14 Mar '10

Howdy, this might be slightly off-topic here, but. I know they likely only sold 50 or so of these units but I was wondering if anyone still uses them that has any technical prowess with these units. I've run into a recurring technical snag and obviously since they are EOS (and Avaya seems to have cleared the support staff) I can't really get 'official support' for it. So if anyone who has touched one of these recently or still uses them can hit me off-list I would be grateful, I am also looking to purchase used CNA 336s for spares if anyone has any that are currently being used as a coffee table. Have a nice weekend. -Drew

4bytes ASn and RFC1745
by Bit Gossip 14 Mar '10

experts, what are the consequences of 4bytes ASn (RFC4893) for RFC1745 - BGP4/IDRP for IP---OSPF Interaction? In particular with regards to storing the AutonomousSystem in the lowest 16 bits of the External Route Tag (=32 bits)? Thanks, bit

YouTube AS36561 began announcing 1.0.0.0/8
by Nathan 13 Mar '10

13 Mar '10

Hello, I'm hoping to alleviate the "what's going on!?" type messages here this time. :) Here's an except from the APNIC provided LOA I provided to a couple networks, to carry a new announcement... "To whom it may concern, APNIC and YouTube are cooperating in a project to investigate the properties of unwanted traffic that is being sent to specific destinations in the address block of 1.0.0.0/8. This address block has been recently allocated to APNIC from the IANA, and APNIC and YouTube are wanting to undertake this investigation prior to the commencement of ordinary allocations. Accordingly, APNIC authorizes AS36351 to periodically advertise a route for 1.0.0.0/8 from now until 21 March 2010, and requests that AS36351's peers and upstreams accept this as a legitimate routing advertisement." In a continuation of last weeks experiments... we are now announcing 1.0.0.0/8 instead of 1.1.1.0/24 and 1.2.3.0/24. Cheers ,N (nathan(a)youtube.com - AS36561)
