OK, sorry, I think we're addressing different points of the same comment. I was looking very much at the second half of "all residential users get PI so that if their ISP disappears their network doesn't break", ie the reason *why* they'd want PI. I assumed that was "disappears" as in "has an outage", rather than goes bust, user changes ISP etc - and if you've only got one ISP, you don't need PI or ULA to have *local* connectivity work through an ISP outage. I agree, on the current routing platforms we have, PI for every end site is insanity. Whether we should be looking for routing platforms (or a different architecture - LISP?) that allows PI for every end user is a different question... Regards, Tim.

datacenter traffic distribution
by paljak＠mit.bme.hu 01 Nov '10

Hi, I'm wondering if there's a reliable and public survey, statistics about the distribution of datacenter (or cloud, if you wish) traffic, according to protocols or traffic types? E.g. the share of iscsi/fcoe/etc in storage, or the share of TCP/UDP, and so on. For general, Internet traffic, i've found several, for example: - Cisco Visual Networking Index, http://www.cisco.com/en/US/solutions/collateral/ns341/ns525/ns537/ns705 /ns827/white_paper_c11-481360_ns827_Networking_Solutions_White_Paper.ht ml - Arbor Networks survey, http://www.arbornetworks.com/en/arbor-networks-the-university-of-michig an-and-merit-network-to-present-two-year-study-of-global-int-2.html I'd be interested in seeing something similar for datacenter traffic, for research purposes. Thanks for you help in advance, Gergely -- Gergely Paljak

Clarification from Pica8 (was Fwd: Mystery open source switching company claims top-of-rack price edge)
by Christopher LILJENSTOLPE 01 Nov '10

01 Nov '10

I just talked to Lin Du (who I worked with when I was at Woven), who is the current CEO of Pica8. Don't know anything about the product, but this didn't seem like Lin's style. Turns out Fontaine GUILLAUME has registered pic8.org(a)gmail.com, has no relation to the company - and is trying to prove to them that he should be a reseller. Lin has told GUILLAUME to stop (not that that will do any good). Some e-mail fragments below.

Optical Wireless
by james edwards 31 Oct '10

31 Oct '10

I am looking for some vendors that make PtP optical wireless (laser) gear. I have a project where I have to link 2 buildings separated by a 5 lane road. Buildings are at least 10 stories high. Multiple reasons why RF (WiFi) or fiber under the street will not work, plus some layer 8 issues. I need 100 mbs, Ethernet is the protocol transported. PoE would be nice but not a show stopper. Anyone have experience with this kind of gear and can suggest a vendor ? Thanks, -- James H. Edwards Network Systems Administrator Judicial Information Division jedwards(a)nmcourts.gov
