The one item I've found missing in the open source NMS tools I've examined is functional and aesthetically pleasing mapping, i.e. the big picture network map with ability to drill down. If anyone has found a nifty solution for this please let me know! Regards, Jade Jade E.

OT: Slowing the speed of light to improve networking?
by Fergie (Paul Ferguson) 29 Sep '04

29 Sep '04

A colleague brought this article to my attention. Slightly off-topic, but interesting nonetheless: "Researchers at UC Berkeley, along with scientists from the University of Oregon and the University of Illinois, say they can slow the speed of light in a way that could help speed the delivery of movies to your PC. "Scientists at the university managed to slow the speed of light traveling through a semiconductor to 6 miles a second, or 31,000 times slower than the 186,000 miles per second that light normally travels in a vacuum. "Slowing the light pulses could lead to a more orderly traffic flow in networks, ....."

Bill, With the right amount of prep work and understanding of how the stacking works, you can control everything you complained about. I complained about the same stuff until I read the document that explains how to: 1) Renumber a switch in the cluster (and all of it's interfaces with it) 2) Hot swap a new switch into the cluster 3) - and this one's sweet - upgrade the s/w on the entire cluster in one shot, even if they're different models 4) Control which switch is the master so that adding a new switch to the stack doesn't chance screwing up your configs. 5) Permanently remove all stacking config from the switch The actual backplane has lived up performance wise in the testing I've done, but I haven't come anywhere near testing it to 32gbps. Just the same as thousands of people have wiped out every VLAN on their network by putting in a switch with a higher VTP revision number with no VLANs defined, it takes a learning curve to work well with these suckers. Granted - the software has been somewhat buggy - but those aren't the merits I'm debating. http://www.cisco.com/en/US/customer/products/hw/switches/ps5023/products _configuration_guide_chapter09186a00801a6558.html > -----Original Message----- > From: owner-nanog(a)merit.edu [mailto:owner-nanog@merit.edu] On > Behalf Of Bill Woodcock > Sent: Wednesday, September 29, 2004 11:33 AM > To: Deepak Jain > Cc: Frederic NGUYEN; nanog(a)merit.edu > Subject: Re: 10GE access switch router > > > On Tue, 28 Sep 2004, Deepak Jain wrote: > > Just a note, if you want redundant 10GE uplinks you > need to get two of > > these and stack them.

Re: 10GE access switch router

Thanks to everyone for your answers. Actually it would only be an access switch router. BGP is not really necessary. OSPF or static routing would be just fine. The most important need is wire-speed switching/routing capabilities and multicast support. IPv6 support may also be of use. Fred ----- Message d'origine ----- De : "Erik Haagsman" <erik(a)we-dare.nl> À : "Frederic NGUYEN" <fnguyen(a)t-online.fr> Cc : <nanog(a)merit.edu> Envoyé : mardi 28 septembre 2004 22:54 Objet : RE: 10GE access switch router Depending on what Layer 3 features you need you might check out Foundry's new FastIron Edge Switches, the FES4xx: http://www.foundrynet.com/products/l23wiringcloset/fastiron/FESX424_X448.ht… Don't support BGP afaik, but can run basic routing and OSPF quite well in a bit less than 2U. I'd expect a small formfactor NetIron with 10GigE support to come out as well which could also solve your BGP issues (depending on the amount of traffic), though I doubt any of their switches are able to route a full 10 GigE worth of traffic. Extreme also has a Summit doing this, with just about the exact same features, though usually a bit more RAM (and buggier L3 code ;-) Cheers, Erik

The Cisco Catalyst 3750G-16TD is a 1RU switch and I believe has a single 10GE Xenpak uplink; not sure how many ports you are looking for.
