Web Hosting Talk : Web Hosting Main Forums : Colocation and Data Centers : Bandwidth limiting via switch? NetSys switches?

[MrZillNet]

As we all know, there are a couple different ways to implement bandwidth limiting.

Does anyone have a recommendation for a 10/100 switch that will do this?

I saw this switch, which is not priced too much more than a basic managed switch:

Does anyone have these NetSys switches in production? Or, what DO you have in production that you like?

A cisco 2950 would do it and probably functions much better for the datacenter environment.

You brought up NetSys; you might as well have said Dlink. Nothing compares to Ciscos for this task (unless you don't mind the color purple)

Unlike every other vendor with a policing feature, Cisco lets you set a burst margin. This is very important for tcp-oriented (read: 99.9% of your) traffic because your burst margin needs to be variable based on the amount of in-profile traffic that you're allowing. Otherwise, tcp closes your window(s) too narrow and every tcp stream flowing through your switch suffers from worse throughput than if you had a switch (like the Cisco 2950) that lets you set a proper burst margin. The cheaper switches usually use staticly computed burst, which may or may not work in any given situation.
