10/100 Switch... HULP

[JBS]

I need a 10/100 switch which supports per-port input rate limiting, output rate limiting, and traffic shaping.

It has to be either 24-Port or 16-Port...

The only problem im having is finding out weather it Does or Doesnt have support to limit the transfer rate without having to buy it... Plz Hulp

Here are some switches, but I cannot answer your question about them limiting the transfer rate. My gut feeling is that they wounld not, but check them out. Here is the link: <A HREF="http://www.linksys.com/products/group.asp?grid=29" target="_new">Linksys</A>

I have a feeling you'll be after a Cisco switch, and I also have a feeling you won't like the price.

im not sure about the lesser models but the cisco 2500 series switches will do the trick, but they aint cheap! you may be better off throttling speed at the workstation.

I've seen some net admins implement software to drop packets, causing the TCP/IP protocol to naturally level off at a certain desired speed. For most purposes I believe it worked pretty well... from what I understand of what he told me about it, TCP/IP ramps up the transfer speed from "safe & slow" at the start, and brings it up to the highest reliable speed - this meaning that when it notices dropped packets it slows down. At least, this is what he told me, he could have been BS-ing to get me to go away and stop asking him about his job. ;-)

some campus companies did use this as a method of "punishment" for abusive clients tho. :-D If they noticed somebody uploading gigabytes per day, they'd auto-throttle his connection by dropping packets until he was transferring a reasonable amount per day, with control all the way down to sub-modem speeds for the real nasty ones.

I believe this works well with gaming, i.e. doesn't kill the online game, but I could be wrong and it probably depends on the severity of your darth-vader-esque network-choke.

i dont know about that automatic throttling function, ive never heard about it. dropping packets would make the computer have to retransmit them, effectivly slowing their connection down, but that would put more strain on the network.

yes, but the important thing is that the (small amount of) extra strain you get is on the bigh-bandwidth, free, internal side of your uplink, and any reason I can think of for limiting transfer rates at a switch would be to prevent individual users from using too much of the uplink bandwidth. This can actually result in much nicer internet performance for everybody.

good point.
