Abstract
Abstract Under VTAM, or similar-type data communications system, co-executing "partner" processes typically exchange data via SEND and RECEIVE requests that are processed by VTAM. A method in accordance with the invention provides a way for optimizing this data exchange process. The optimized method bypasses VTAM to provide significant savings of system resources and improved execution speed over that required for VTAM to process the same SEND and RECEIVE requests.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
165 words
A Bypass Send and Receive method, executed by a machine which is also executing (1) a communications program VTAM, (2) a first application program, and (3) a second application program, for converting an outgoing data stream from the first application program to an incoming data stream for the second application program, said Bypass Send and Receive method comprising: (a) receiving a SEND request from the first application program, said SEND request having a data portion representing an outgoing data stream; (b) receiving a RECEIVE request from the second application program, said RECEIVE request having a request-parameter-list portion; (c) storing the SEND request's data portion in a buffer memory, said buffer memory having an address; (d) notifying the first application program that the SEND request is completed; (e) converting the outgoing data stream to an incoming data stream by modifying the RECEIVE request's request-parameter-list portion to include the address of the buffer memory; and (f) notifying the second application program that the RECEIVE request is completed.
Claim 2
Dependent Claim
165 words
A Bypass Send and Receive method, executed by a machine which is also executing (1) a communications program VTAM, (2) a first application program, and (3) a second application program, for converting an outgoing data stream from the first application program to an incoming data stream for the second application program, said Bypass Send and Receive method comprising: (a) receiving a SEND request from the first application program, said SEND request having a data portion representing an outgoing data stream; (b) receiving a RECEIVE request from the second application program, said RECEIVE request having a request-parameter-list portion; (c) storing the SEND request's data portion in a buffer memory, said buffer memory having an address; (d) notifying the first application program that the SEND request is completed; (e) converting the outgoing data stream to an incoming data stream by modifying the RECEIVE request's request-parameter-list portion to include the address of the buffer memory; and (f) notifying the second application program that the RECEIVE request is completed.
Claim 3
Dependent Claim
37 words
The Bypass Send and Receive method of claim 1, wherein one of said first and second application programs is a logical unit engaged in a communications session with the other of said first and second application programs.
Claim 4
Dependent Claim
30 words
A program storage device readable by a machine and encoding a program of instructions for performing a Bypass Send and Receive method in accordance with claim 1 or claim 2.
