multiple connection teaming...

[sccs]

hi guys..

i currently have wingate setup as connection teaming to allow my multiple modems to download and increase me dl speed.

now i have 2 * 10 mb which works great and i can get 18mb dl.

however if i add another 10 mb i can still only get 18mb

and if i make it 2 * 20mb i can still only get 18mb.

all modems will max out running through wingate on the own so i know the modems and connection settings are OK.

any ideas...

thanks,..

When you say "teaming" do you mean gateway selection for proxy?

[sccs]

basically i connect 2 modems to my pc via eth cards,

in wingate i create 2 tcp mapping services

i enable the default mapping to my server addy and set the correct port.

i then bind one to eth0 and the other to eth1

then i set gateways, again one to eth0, any gateway and the other to eth1, anygateway.

everything else is default.

both service 1 and 2 will both max out at 20mb when used alone. but if i use both services i only get 18mb.

Just a thought in passing - what is the max throughput your PCI bus can support?

thanks for the reply...

cand find ne figures quoted ne where in manuals or on site...

mb is a giga-byte GA-7NNXP

i can acheive 100mb transfer accros lan using hub or crossover so i assume that should be ok?

You're right - a single nic would give a higher average throughput per nic (throughput/1) compared to multiple interfaces (throughput/2 or 3) but maybe I was off track with that thought anyway.

Could it be that you're maxing out one of the links at the exchange, your ISP or elsewhere en-route? - sounds more likely after considering your most recent post and re-reading the others.

One other thing, what is the CPU in that machine?

You could be coming up against a CPU performance limit.

i have the athlon xp3200.

when running flat out @ 18mb im only hitting 50-60%cpu usage..

im not maxing the links... i can put both modems on differnt machines and max the 20mb on each no problem...

Still sounds like a hardware bottleneck limit being reached somewhere, something hitting max throughput - if not the outside network then almost certainly your server.

Hi

I'm wondering if there's a way to use ENS rather than TCP mappings.

With TCP mapping proxies, the packets have to come into the WinGate machine, go up the TCP stack to WinGate, be received, then re-queued back down the stack when they are sent. When the ENS sees the packets going out again, it sets the gateway MAC and interface.

How do your lan clients connect to the TCP mappings? Are they intercepted, or do they connect directly? Are these on the same interface, and different ports, or different interfaces (for the incoming connections from your LAN clients).
