Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I am looking for a way to create a lower bandwidth restriction on an interface. I have an ethernet interface that I want to restrict to a maximum of T1 throughput. 1. Is there a way to do this (easy or kernel hacking) What happens, i.e. the mechanics, when there is a higher capacity link feeding into a lower capacity link. Where does all the data go? I know it is buffered to an extent, but that has limits. Do the packets get dropped? I seem to remember an ICMP type that indicates transmission of too much data and for the sender to cut back or something. All thanks, Dan -- danj@3skel.com Dan Janowski Triskelion Systems, Inc.
