There is still a problem whereby a large packet in transit can't be interrupted by a smaller packet. One solution I saw for this when doing VoIP over ADSL was using PPPoE and setting it up for multi-link over one link. The packets get fragmented into smaller pieces and the fragments of smaller packets get higher priorities. Not sure how much over head it cost, but ISTR it wasn't too bad. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
