@ Rizla - interesting point, of course you refer to your own line when you say 7db requires no error correction, longer lines do, heck my 26db line gets 30 crc's per day...  :-)

Offtopic : Is broadcom the only chipset builder that allows telnet?

No what I mean is that as the ADSL/VDSL speed increases then the demands on the cpu core doing that work increase.

I only gave that (DG834GT) as a minor example.

Oh and anyone who thinks (DIY) GigE around the house is going to be error-free - best of luck.

[Chrysalis]

true, on my adsl line I often had the modem seizing up, the amount of error correction and bitswapping was simply too much for it.

do routers often have lan and wan processing seperated to seperate processor core's?

some examples I do have.

my billion 7402nx has a wan throughput limit of about 45mbit/sec, discovered when I had FTTC installed, dissapointed as is otherwise a great router.  Yet it can handle gigabit lan.  My typical lan throughput I think is 600mbit or so. (on all gigabit routers I tried).
This made me buy my asus rt-n16 which can handle up to around 120mbit or so so full FTTC speeds.  Has gigabit lan.
The hh3 can handle 300mbit speeds in excess of all the above routers.  But its possible the above routers have seperate processors to handle lan traffic.

Somewhat topically Sky are now asking for beta-testers for a "new edition" of their hub :

Maybe prepping for self-install? Your guess is as good as mine....

Depends on the router but in general no - enterprise level routers/switches often do, but the cores there will be for things like packet forwarding, embedded services (firewall etc), management/punt traffic etc etc.

Lose the xDSL part of the routers we're talking about and what's left would have the cpu cycles to route at above 100Mbps - if it were that simple, which of course it isn't as the xDSL frontend is part of the SoC.

Switching (LAN-LAN) and routing (LAN-WAN) at line speeds are different beasts too, especially at above 100Mbps when you're using NAT and a firewall.

Best bet really (IMHO) is a dedicated modem feeding into a bog-standard ethernet router. Costs more in total but you have the modem (bridge) cpu dealing with xDSL and not having to mess about with routing/firewall/NAT; you have the router cpu doing routing/NAT/firewall. Horses for courses.

I've always said that we are moving towards needing something along the lines of the computing power of a netbook (?intel atom?)- if users want an all in one FTTC/router/wireless/NAT handling capable unit.
All means biggers cases, more complexity, fans whatever etc.

[guest]

Oh gods you don't want an Atom, they're garbage for this sort of work. Frankly they're garbage for most sorts of work but they're x86 compatible so they get used for Windows. I have a server running on a dual-core Atom but that's really just for backups/DNS/streaming server etc - if I tried to make it route stuff it'd struggle to cope.

Most of the current(ish) ARM cores would do this really well and at a low cost (power and cash) but they're not well represented in the consumer router market AFAIK, so startup costs would be higher than just grabbing a Broadcom SoC and re-rolling Busybox....

The first unloved Home Hub 4 is up for sale on a famous auction website 

(Click to enlarge)

With a starting price of £59.99, it's probably for the connoisseur only!  (that's more than my PC is worth!)

cheers, a

[c6em]

Blimey that's cheap!
Try this from the BT shop....yours for only.....£109

[Black Sheep]

We don't know it's "Unloved", Asbo ?? In fact, it may be that the HH4 has itself asked to be auctioned off, due to the EU only having lowly ADSL speeds !! 
 

[burakkucat]

My 'Best offer' of £0-59 for it was turned down. 

[GigabitEthernet]

And there's another Home Hub 4 on the 'bay; yours for - you guessed it, the fantastic price of just £65.

[Chrysalis]

What I do like what they did is they made it fit thru postboxes, meaning no more waiting around for delivery.

[smiggy]

FYI, 190837397709 will take a best offer of £45+postage, maybe 1 or 2 less. He declined my offer of £34

[asbokid]

Hello Smiggy!  Fancy meeting you here!  We was told you'd emigrated to Oz!  Just here while the weather's good?!

cheers, a
