Announcing and seeing them work "on the street" are two seperate things. Writing an driver to support the driver will be the realitively easy part of the ATM support problem. We will also need the support for creating/destroy the Permanent Virtual Circuits and Switched Virtual Circuits, the interface API, the LAN Emulation (ATM standard) or the IETF TCP-over-ATM support, end-node's responsibility of Flow control which depends on which UNI we support. Be very careful in purchasing an ATM card. Does it work with your switch, which UNI, AAL, media does it support, etc. Also, does the card re-assemble the AAL5 packets before sending it to the OS (I am told this make a BIG performanace difference). There are several people at various stage of working on ATM on FreeBSD. I would like to get a common base of standard that we can aim at reaching. The ATM mailling list has just been start and the organizational effort of choosing what we want has really not even begun. --mark.
