There is still a problem whereby a large packet in transit can't be=20 interrupted by a smaller packet. One solution I saw for this when doing VoIP over ADSL was using PPPoE and=20 setting it up for multi-link over one link. The packets get fragmented into= =20 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. =2D-=20 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 --nextPart1365293.5FHxlCvz8t Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQBCri385ZPcIHs/zowRAlWsAJ4o+rHIG7OLn30dz3tcGF8Bvc45wQCfbN/X Lx+rY29F5o2vOY6yxA26xIE= =C5MR -----END PGP SIGNATURE----- --nextPart1365293.5FHxlCvz8t--
