-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 > Netoptics work great. Check out their aggregation taps. Some 4-port fiber gig taps, including Netoptics ones, drop frames when aggregate utilization exceeds 1 Gbit/s. That can be 500 east + 501 west or 1001 west, or 251 in each of 4 ports or whatever. I'd heard about a kiddie porn case getting tossed because the defense successfully argued law enforcement's tap may have dropped frames. I didn't believe it until I measured this myself with a packet blaster. I used VSS taps in my tests. Brian Chee of the University of Hawaii tried this before me with a Netoptics tap, with similar results: Endicott-Popovsky, B.E., Chee, B. and Frincke, D.

Can a Comcast.net email admin please contact me? One of your non-outermost email servers is running an SPF/SenderID filter (so all messages from domains with -all SPF/SenderID records are getting rejected, regardless of sending server). Thanks, Adam Stasiniewicz

I guess I mis-read Chiyoung's shorthand, i.e., "giga fiber", which I took to mean beaucoup fibers. Please excuse the noise. Frank A.

Unless I'm misreading the requirement, this sounds like a job for a Calient or a Glimmerglass optical switch, capable of non-intrusive bridging and/or insertion. For large jobs, in any case. A demo of the Glimmerglass device can be viewed on the company's "Government Signals Monitoring and Analysis" page: http://www.glimmerglass.com/defense.aspx Frank On Thu Nov 29 22:22 , "Christopher Morrow" sent: >On Nov 29, 2007 6:58 PM, Sean Donelan sean(a)donelan.com> wrote: >> On Fri, 30 Nov 2007, 정치영 wrote: >> > Because of some reasons, I have to install some giga fiber tap for packet >> > monitor into critical lan point, and the taps must be there permanently. >> >> Some folks speculate the NSA likes using ADC monitor and splitter modules >> http://www.adc.com/Library/Literature/104215AE.pdf >> >> I prefer using Netoptics network taps >> http://www.netoptics.com/ >> > >I've used both of these, I like them both, so 2 votes for these 2.... :)

Re: [nanog] Connections among ASes (fwd)
by Chengchen Hu 30 Nov '07

I agree that IXPs could be connected. Let me explain the problem more clear. Suppose the following example. ISP A has a router A1 in IXP1 and a router A2 in IXP2; and ISP B has a routers B1 in IXP1 and a router B2 in IXP2. It is possible that we have DIRECT link A1A2 and B1B2 to connnect two IXPs, but I don't think there may be DIRECT link like A1B2 or A2B1. Since it should be much cheaper and easier for ISP A and ISP B to be connnected in the same IXP using links like A1B1 or A2B2. Am I right? So in your case, all the suppliers and peers DIRECTLY connected to any one of your routers are located in the same IXP? ------------------------------------------------------------- From: Tuc at T-B-O-H.NET Data: 2007-11-29 19:29:12 To: huc(a)ieee.org CC: Subject: [nanog] Connections among ASes (fwd) > > > Hi, > > I am not sure about whether the following two conditions are true or not: > > 1) there is no such a direct link between two routers located in two Internet eXchange Points-IXPs (even in same city) if they are from different ASes. For example, a router A belongs to AS x located in IXP1, and router B belongs to AS y located in IXP2, there is no link between A and B. > 2) small AS will not use one router to connect to 2 different providers in differnet IXPs. It is much cheaper using one router to connect with different ASes in a same IXP. > Hi, REPLY IS OFFLIST.......... Not quite sure I understand this... But, giving the old college try (Even though I didn't go to college)... Just because someone is at an IX, doesn't mean they peer with EVERYONE on the IX. IX's can also be interconnected, so even though ISP1 is at IX1 in 1 place, and ISP2 is at IX2 in place #2, they potentially COULD be interconnected but don't HAVE to be. IX's inherently aren't interconnected, but there are some places where they are. NYIIX has 2 sites. NYCX has 3. NYIIX and LAIX were supposed to be tied together, but not sure if it ever happened. As for small ISP with 1 router... When we were at the NYIIX, we had 1 router (Cisco 6509) and connected to 3 bandwidth suppliers AND ~40 peers at the NYIIX. We also had 2 routers, both were connected to each other, as well as both to our suppliers + our Peers at the NYIIX peered at 2 addresses with us. We had redundant routers, so never saw the need to split functionality apart. Tuc
