Internal PCI/PCI-E cable modem and/or ADSL2/2+ cards? - Page 2

Yes I know this is an old posting but I couldn't resist to state the obvious!!!


Internal PCIe cards are a GREAT idea.....


Whether it be for:

ADSL 2/2+ PPPoE/A Annex A/M ITU mode G.992.5
VDSL2
Or Residential Fiber running at 100-1000Mbps (ok no need for modem as this can use an ethernet or fiber port)
Even MPLS can be hooked up


The reason I state this is that it's actually cheaper to buy something like a Quad Core CPU with 1-4GB RAM and use the box as a router!!!!!

Taking fact into things, a Cisco 29xx series router costing anywhere between: $700-5000 (US) depending on configuration is actually less powerful!


The quote by Cisco is 75Mbps routing capability rendering any high performance line useless.... if you add to that inter-vlan routing, IPS/IDS, firewall, ACL's, Dial-in SSL or Site-to-Site IPSEC/GRE VPN tunnels, dynamic routing using inter-area OSPF or BGP, QoS etc......

(yes some of us at home run all these smile.gif )

The router will get rendered useless once the traffic flows start piling up.


I've actually measured that once the tcp/ip flows for UDP/TCP traffic start getting into the 1000s which is so easy using something like rtorrent with 90 concurrent downloads, something like a Cisco 857W, 877W, and 1801W all practically give up!

I have all the above and measured with SNMPv1, graphed with RRD tools and Cacti to MySQL backend and basically the CPU was driven to 100%!!!!!


Now as a UNIX and Cisco engineer that tells me that it would be easier and cheaper for the standard consumer to go buy a Mini-ITX based system running something like an Intel Atom D510 or D525 CPU with 1-2GB RAM would get unbelievable performance using a platform such as OpenBSD or FreeBSD coupled together with a subset of Quagga called Zebra:

www.quagga.net/

or even Vyatta which is Linux based and free for the community edition.


For more high performance - a SuperMicro or Chenbro chassis coupled together with a single or dual socket Xeon(between 4-6 cores) running 4 - 8GB RAM should even suffice for most enterprises at large scale 1000+ users.


Couple that to your favourite switch vendor: Cisco Catalyst 2960 for a simple L2 based switch and you have yourself a nice setup.... though one would need to tune VTP, STP, CDP, and ARP Caching.


But yeah basically......


Actually I'm even betting that a used Sun Fire V210 with dual SPARC CPU's and 4GB RAM running xBSD would pretty much rock in this occasion. Ok no xDSL card for SPARCs as architecture is slightly different but as a routing solution it would be unreal and cheap too. Not to mention the Big Endian CISC CPU inside and for the best part - one can link a DEC VT100 compatible terminal to it so no need for stupid and useless GFX cards.... yes it's same for most business network vendors such as Cisco, Hp, Juniper et el..

just googled this up, sorry for Necro but this is EXACTLY what the OP is looking for, i hope it helps, i'm looking for one to go into my spare PCIe x16 slot no luck so far, i remember 5 years ago these internal modems were EVERYWHERE, what happened?

I have a pile of PCI DSL cards that I've been selling on eBay, if you'd like we can talk about me sending you one to test and let us know if there is an advantage over an external modem, all i ask is you cover shipping.

I can get you model and specs once i get home if your interested.
