Abstract
In a distributed system, such as a local area network having a facility for synchronous remote procedure calls and multi-threading, an interface mechanism for linking client workstations on the distributed system with external switched communications networks is provided. The interface extends the remote procedure calling facility beyond the distributed system by classifying the different types of remote procedure calls that can be issued to a switched communications gateway in the distributed system, and permitting the issuance of multiple threads of control, according to the type of function the procedure call represents. Related functions are forced to execute sequentially at the gateway, while those classified as unrelated functions can execute sequentially. The advantages of heterogeneity and concurrency of the distributed system are thus extended to its switched communications links with external switched networks.
