High performance machine for switched communications in a heterogeneous data processing network gateway
First Claim
1. An interface mechanism for a switched communications gateway in a distributed computing network comprising:
- means for issuing multiple remote procedures calls between at least one computer and the gateway across the distributed network;
means for concurrently processing the multiple remote procedure calls between said at least one computer and the gateway across the distributed network;
means for identifying remote procedure calls for related functions for effectuating switch communication link; and
,scheduling means for sequentially processing remote procedure calls for the related functions at the gateway.

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.
