Determine switch buffer size

Hi everybody,

I need to calculate the tcp buffer size of a network switch, since it's not specified in the manual; how do I do this?

I have some machines connected to the switch and I can run some socket tests written in C between these machines (I can choose how many bytes to send and calculate the senders' and receiver's bandwidth) and I guess I need to keep sending more and more data until I see some slowdown in the sender's bandwidth (because that means that the senders are sending more data than the switch can handle), but I'm not sure about this.

Thanks for your help!

RUBY-SWITCH(1)															    RUBY-SWITCH(1)

NAME
ruby-switch - switch between different Ruby interpreters USAGE
ruby-switch --list ruby-switch --check ruby-switch --set RUBYVERSION ruby-switch --auto DESCRIPTION
ruby-switch can be used to easily switch to different Ruby interpreters as the default system-wide interpreter for your Debian system. When run with --list, all supported Ruby interpreters are listed. When --check is passed, ruby-switch will check which Ruby interpreter is currently being used. If the settings are inconsistent -- e.g. `ruby` is Ruby 1.8 and `gem` is using Ruby 1.9.1, ruby-switch will issue a big warning. When --set RUBYINTERPRETER is used ruby-switch will switch your system to the corresponding Ruby interpreter. This includes, for example, the default implementations for the following programs: ruby, gem, irb, erb, testrb, rdoc, ri. ruby-switch --set auto will make your system use the default Ruby interpreter currently suggested by Debian. OPTIONS
-h, --help Displays the help and exits. A NOTE ON RUBY 1.9.x Ruby uses two parallel versioning schemes: the `Ruby library compatibility version' (1.9.1 at the time of writing this), which is similar to a library SONAME, and the `Ruby version' (1.9.3 is about to be released at the time of writing). Ruby packages in Debian are named using the Ruby library compatibility version, which is sometimes confusing for users who do not follow Ruby development closely. ruby-switch also uses the Ruby library compatibility version, so specifying `ruby1.9.1' might give you Ruby with version 1.9.2, or with version 1.9.3, depending on the current Ruby version of the `ruby1.9.1' package.
