Hi there!
I'm currently reading a CCNA book, and I've got some questions I can't find 
an answer to.
The Carrier Sense Multiple Access with Collision Detection checks if there 
is any traffic on the wire and then starts to send the host's data, if 
someone tryes to send at the same time, the sending host sends the "trying" 
host a jam signal that would make the trying host to wait.If the trying host 
get's 15 jam signals at one time, it times out.

Some questions came up at this chapter. Is there any possibility to write a 
program that sends jam signals to other hosts within the same broadcast 
domain until they timed out and died ? Does this mean that IF you where to 
write this program, actually needed to rewrite a part of the  tcp/ip 
protocol stack ? Isn't this a big issue?

Sorry for my bad english..

Best Regards: Fredrik Wessberg
