Abstract
A system and method for improving the efficiency with which data communications are passed through a protocol stack. Protocol layer modules within a protocol stack built upon the Streams framework are modified to establish tight embraces between adjacent modules. A tight embrace may be established by passing from one, upper, protocol layer module to its adjacent lower protocol layer module a pointer or reference to the upper module's functionality (e.g., rput) for reading a data communication into the upper module from the lower module. Similarly, the lower module passes the upper module a pointer or reference to its functionality (e.g., wput) for writing a data communication into the lower module from the upper module. After a tight embrace is established, the protocol layer modules can directly invoke each other's functionality, without incurring the overhead associated with the Streams framework's 'canputnext' and 'putnext' messages.
