Rob, Ok. Do you want to share your experience? No point of taking this offline! Are you looking at market share, attributes and functionality on these new appliances? In this competitive world everyone has a say to the well-known Cisco and Juniper product set. What is the ASIC board type across all products? I can't see any 40Gig card support ....or any new OS features like most have available on their roadmap. http://www.geant2.net/upload/pdf/GN2-07-154v7-Deliverable_DJ4_2_2_Feasibili… .//ID and yes, looking for a job! --- On Wed, 2/11/09, Robert D.

We used DXM10 at Caltech to connect the switches at colo in downtown LA during supercomputing 2008. Configuration is pretty straight forward and box is well stable. No errors / link flaps seen on the ports. Few of the ports were LR for 7606 and some were SR for servers connecting Myricom 10GE NICs. -Azher

Hi I would like to ask your professional experience about switch throughput I have Gig Switchs eg: H P3400 /3500, cisco c4 948../ dlink In their spec, they said that it can handles Gig So far, I couldn't see their ports are used up over 200M in mrtg graph when I try to transfer 3G size files to files between computers ls there any limitation in those switchs? or I have to do configuration eg: put it full duplex instead of auto Thank you for your help

Call for data: IPv6 enabled service logfiles for analysis
by George Michaelson 11 Feb '09

11 Feb '09

Call for data: IPv6 enabled service logfile analysis APNIC is seeking operators of high-traffic webhosts, and other public facing services who can provide logfiles for their IPv6 enabled instances. Our intention is to analyse these for the distribution of IPv4, and the various sub-classes of IPv6 (native, tunnelled, Teredo, 6to4). APNIC will of course respect client privacy and sign an NDA, only abstracted data outcomes would be presented from any participant. -All participants would be acknowledged for their support in any presentations. While our preference is for access to raw logs, there may be people out there who cannot share this due to contractual or other restrictions. If you are willing to filter data according to our example Perlcode, we'd be happy to receive abstracted data if neccessary. Our tools assume the apache 'combined' log format, or things which can be simply converted to a close analogue. If anyone is interested in participating in the data collection exercise, please contract research(a)apnic.net -George

97.128.0.0/9 allocation to verizon wireless
by Jeff S Wheeler 10 Feb '09

10 Feb '09

Dear list, Since IPv4 exhaustion is an increasingly serious and timely topic lately, I would like to point out something that interests me, and maybe everyone else who will be spending a lot on Tylenol and booze when we really do run out of v4 IPs. I have trouble understanding why an ARIN record for a network regularly receiving new, out-sized IPv4 allocations on the order of millions of addresses at once would publish a remark like the one below, indicating that Verizon Wireless has about 2 million IPs allocated. OrgName: Cellco Partnership DBA Verizon Wireless CIDR: 97.128.0.0/9 Comment: Verizon Wireless currently has 44.3 Million Comment: subscribers with 2.097 Million IP addresses allocated. RegDate: 2008-04-14 This may be unscientific and full of error, but if you add up all the IPs behind AS6167, you get a pretty big number, about 27 million. If I make more dangerous assumptions, I might argue that a network with a need for 2 million IPs, at the time this /9 was handed out, already had about 19 million. Then it received 8 million more. Sure, smart phones are becoming more popular. It's reasonable to assume that virtually all cell phones will eventually have an IP address almost all the time. But that isn't the case right now, and the ARIN is in the business of supplying its members with six months worth of addresses. If everyone is expected to run out and buy a new phone and start using "the Google" right away, and stay on it all the time, maybe cellular operators really need a lot more IP addresses. If not, why does Verizon Wireless have 27 million IPs when the above comment indicates they need only a tenth of that? - j

RE: Private use of non-RFC1918 IP space

Michael Hallgren <m.hallgren(a)free.fr>: > > Really really LARGE scalability testing that needs more addresses than > > RFC1918 gives you. > > Use IPv6. For an IPv4 scalability test? Interesting idea... Apart from the basic incompability here, my opinion of IPv6 is that it just gives you 2^96 more addresses to repeat all the old mistakes with. --Johnny
