Abstract
When a TN3270 client (14) uses the Transmission Control Protocol/Internet Protocol ("TCP/IP")to initiate contact with a TN3270 server (18) to obtain access to an applications program running on a host (12) with which the server (18) employs the Systems Network Architecture ("SNA")protocol to communicate, the server's SNA physical-unit process sends the host's systems service control point an SNA NMVT message that includes a physical-location subfield in a product-set-attributes subvector of a product-set-ID vector. The physical-location subfield includes the client's IP address and TCP port number so that host management applications can determine individual clients' usages without interrupting communications with the server.
