802.11b network help

[wangeth]

Any tips on getting a 802.11b networked client and server to work well together? I know I read some posts where it worked for some, but not for others. I have a D-link DI-614+ router w/ some USR PCI wireless cards. Seems everytime I start a high-bandwidth application (like sage), the connection craps out for a second, then reconnects. Doh. Help!

80211.b doesnt have the bandwidth to handle the data flow you need either a or g.

The max quitily I've tried is SVCD. SageTV running PIII733, SageClient running PIII500 (notebook).

How much bandwidth does each pre-recorded stream use?

Are there limits to the amount of streams the server can provide?

Say you wanted to serve 4 clients simutaniosly each with 100mg Nics via a server with 1 gig Nic through a 1 GB to 4 100mb switch.

Would this work?

What server specs would handle this?

Can a recorded movie on the server be accessed by two clients with different start times?

Wow, so many guestions?

Thanks,

I've done 8 simultaneous full qualiy (8Mbit/s) streams from the server at one time when I was first testing SageTV Client.

This was with everything connected 100Mbit Full Duplex to my switch.

Going Server -> 1Gb -> Switch -> 100Mb to clients you could probably get more. Didn't try though, as I don't have any 1Gb equipment at home.

Server specs are going to be bound by the disk subsystem and quality of network controller in the machine (some use much more CPU than others at high utilization). But bottom line is if you have good disk throughput speeds and a decent network controller you should be in good shape. CPU should not be too much of a limiting factor (within reason).

Hope that helps.

Thanks Jason,

Wow 8 streams, thats great!

OK, man I'm going to have to order this up!

Thanks,

Of course your mileage may vary.

But I usually get ~80mbit sustained throughput with my switch and all nics forced to 100mbit full duplex.

So as long as you can keep the bandwith open, you shouldn't have much of an issue I wouldn't think.

Wow, 8 streams, that's very cool.

I designed that code to scale well, but hadn't tested it that extensively yet. Glad to hear it.

And there's no actual limit on the number of simultaneous streams, you'll run out of disk or network bandwidth before the software has any issues.
