Tc is a part of the iproute2 set of utilities that were created to fix some 
of the issues with the original version from my understanding.

Matthew's linux is the PakSecured Linux so he developed a kernel patch to 
use a filter called u32 to filter out traffic by marking the necessary 
packets in some meaningful way to allow the filter to recognize the packets 
to slow the traffic (in this case).  Ingress is an inbound traffic control 
filter so that is limits inbound connection speed. Though I just want to 
limit outbound no inbound.

Egress is just another type of filter and the HTB is also another filer 
except that HTB is probably the easiest to set-up but I would imagine not 
the most powerful.  All of this filtering is done to limit the bandwidth to 
a server/computer so that if you colocate and only get xxx bandwidth you can 
set your server to only allow xxx bandwidth so you never get charged extra 
because by default the kernel will use all bandwidth available to it.  Any 
more questions just let me know...

Thanks,
Nate
