Abstract
Bidirectional communication between one or more workstations which may be operating on one platform such as UNIX, VAX/VMS or NOVELL's NetWare with an event driven database which is operating on a different platform such as QNX is made possible by separating a gateway into two portions with one portion in each platform bidirectionally linked with a pair of BSD socket libraries on each platform.
Claims1
A glassware forming machine comprising
- an event driven database operating on a first platform,
- a workstation operating on a second platform and including
- application means for making and receiving API (Application Programming Interface) calls,
- an event driven database library,
- a gateway library and
- a BSD (Berkeley Software Distribution) socket library,
- said event driven database library bidirectionally interconnecting said application means and said gateway library and
- said gateway library bidirectionally interconnecting said event driven database library and said BSD socket library, and
- a network gateway operating on said first platform and including
- a BSD socket library and
- a gateway Service bidirectionally interconnecting said network gateway BSD socket library and said event driven database, and
- said BSD socket libraries communicating bidirectionally via TCP/IP (Transmission Control Protocol/Internet Protocol) packets,
- wherein said first platform is ONX, and
- wherein said second platform is either UNIX VAX/VMS or NOVELL NetWare.
