According to the Open Group Base Specifications Issue 6, STREAMS provides a uniform mechanism for implementing networking services and other character-based I/O. It is a full-duplex connection between a process and a device. The part working in the process space is the STREAMS head, the part working in interaction with the hardware is the STREAMS driver and between them can exist STREAMS modules to implement different levels of protocols. The Implementation done for the ocera consortium uses internal synchronization mecanismus from Linux and RTLinux to schedule the streams modules and to deliver data from RTLinux, taskless world, to the Linux process space.
