POSIX

POSIX

(Portable Operating System Interface for UNIX) An IEEE 1003.1 standard that defines the language interface between application programs and the Unix operating system. Adherence to the standard ensures compatibility when Unix programs are moved from one Unix platform to another. POSIX is primarily composed of features from Unix System V and BSD Unix. See Single UNIX Specification and UNIX 03.

The driver abstracts proprietary ASIC application programming interfaces (APIs) with standard Linux APIs for the switch data plane configuration.
Sueltz is also going to have to contend with Linux in a more meaningful way than porting Linux to Sun iron and seeing what develops, or adding Linux APIs and ABIs to Solaris so that people who "outgrow" PC iron can move their Linux applications up to a real server like a Sun UltraSparc Enterprise 6500 or 10000.
