OS Router Challenges Proprietary Networking
Jane Walker writes "Dave Roberts talks about Vyatta's open source router and how open source technology may soon alter the landscape of enterprise networking." From the article: "Initially, we believe that the x86 PC running Vyatta -- given the range of hardware that's available in the PC world -- can basically replace the midrange of the router market; to use Cisco terminology and model numbers, simply because it's convenient shorthand, basically from the 2800 series to the 7200 series. There's a whole host of equivalent products from Nortel and Alcatel -- but essentially in that range. I wouldn't describe it as Cisco model numbers so much as T1 branch office to gigabit LAN product categories."
Here's why:
1) it takes an RTOS to make things work well. You can grind all the driver code you want, but an RTOS foundation is required with lots of cache
2) only PCI-X bus gets close, and most 1Us don't have it. That gives you a real ceiling in terms of port-port throughput; don't kid yourself
3) the algorithms needed to maintain cross-bar speed are gruesome. You don't find this kind of code in anything but sledge-hammered C and assembler, and code that only a mother (and an embedded systems engineer) could love. There is very little forgiveness here.
Yes, a 1U can make a decent router. But don't kid yourself into believing that you can beat F5, Cisco, Alcatel, etc.
You can certainly embarrass them, but on the high end, it doesn't work.

All depends on what they provide in the way of PCI/PCI-X cards- or whatever the future buses might be...
I'd say that odds are good you'd get about the same number of media interfaces and what you didn't
have would very probably have a media adapter or bridge that's standalone to take care of the gaps.

...they buy "world-class support", but having tried to use said support on occasion, I can say that I feel sorry for the world. Sure, it's better than a kick in the head, but not so much that it's worth the cost. I believe the record for longest repair ever was at the University of Manchester, in England, where a Cisco router corrupted the 1518th byte in every packet (thus only corrupting packets with a 1500 byte payload or 1496 bytes over 802.1q). Took them NINE MONTHS to fix. The first three of those, they denied there was even a problem.
It's a small world and it smells funny; I'd buy another if it wasn't for the money; Take back what I paid (SoM)
This software would have to offer much more that just WIC modules to even have me consider using it. Cisco routers may have low clockspeeds on the core chip, but its the ASICs that give them value. Also, take the 6509 for instance, slap in a SUP720B and you now have a 720 GBps back plane. No PC could ever hope to do that. Also, configuring a Cisco router is pretty much the easiest thing ever. I haven't checked out the software yet, but it better be much easier. Maybe they should network with the Open Source chipset guys and design some ASICs and all the other niceties.
Trolling for a +1 funny mod, are we?
I don't remember who said it, but this is my favorite quote about Cisco software: "Cisco makes easy things difficult, but difficult things possible."
Combining the above will give you a 3U box (smaller than a 7200) which will route (not switch) 4-5Gbit/s reliable. A 7600 is a lot bigger and a serious sh*tload more expensive. You could buy several identical boxes for redundancy and still keep some change left.
Support is the only serious objection one could have in a FastEthernet-, GigE- or 10GE-world. Luckily I don't need support. I have been supporting stuff like above for ten years so I can manage. I can even support your Cisco and Juniper-platforms as well. I can handle my monthly exabyte by myself, thank you very much.
Wideband makes Layer-3 switches that beat comparable Cisco routers hands down. With their nMU (pronounced "NetMU") it makes easy things easy and difficult things easy too. With their 28-port switches, you can get full-duplex, non-blocking Gigabit transfers on all ports simultaneously. And did I mention that they can even do Gigabit over CAT-3 and barbed wire? Also, if you use the nMU control your switches, none of them even need IP addresses. Good luck trying to hax0r a switch with no IP address. Throw in the fact that all their stuff is made in the USA (no off-shore customer support) and costs much less than comparable Cisco gear that doesn't perform nearly as well, and you have yourself a superior product. If you are expanding or replacing your network infrastructure, consider WideBand over Cisco. You'll be glad you did.
***Disclaimer***
I do not now, nor have I ever worked for WideBand, but we use their gear where I work. BTW, there were some guys who ran a Cisco shop in the training class I was in that WideBand offered. Last I heard, they were replacing all their switches with WideBand gear. IMNSHO, WideBand is the best kept secret in networking
