No, what I meant was that mpd doesn't have Charles Mott's alias stuff in it. > BTW, how does mpd do its load balancing ? Does it just send packets to > the interface with the smallest buffer queue ? No, it uses a fairly simple strategy whose goal is to make all of the packet fragments arrive on the other end of the link(s) at the same time. It computes this based on user inputted values for latency and bandwidth. This optimizes for both total bandwidth and total latency. -Archie ___________________________________________________________________________ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com
