Open Network Computing (ONC) is the Sun architecture, with

third party alliances providing the missing pieces. Sun's

RPC is licensed by more than 300 companies, including DEC,

IBM, and Apple Computer. It is a lean, efficient RPC that

is particularly effective for installations not requiring

WAN support. Transport Independent Remote Procedure

Calls (TI-RPC) were co-developed by Sun and AT&T. TI-RPC

runs independent of the underlying network transport,

allowing applications to run unmodified over multiple

transport protocols including NetWare,PCNFS, AIX/6000,

Solaris, UNIX/SVR4, AIX/ESA. NetWise developed the

TI-RPC Application Toolkit source code generation

technology.
