GNSP is a new GCOS 8 communication processor, based on the same physical architecture as IOSP and DBSP, that consists using a Bull Open (AIX) platform for implementing the telecom. I/O tasks of the GCOS 8 Enterprise Server. In that way, it achieves completely the GCOS 8 Twin Architecture. Out of the intrinsic benefits that are described below, the overall architecture is then ready for the next future GCOS 8 evolution.

GNSP, connected to the DPS 9000/TA systems via a "Fast Link" allows any external correspondent of GCOS 8 to access to it : workstations, remote communications servers, remote Interop servers, other enterprise servers, etc…. Consequently, GNSP is a "dedicated" device, that supports Bull supplied communication features. It may be seen as an FCP 8 follow-on, with more performances, more flexibility, more features, etc..

For connection of the remote users above, GNSP offers the TCP/IP suite and, like FCP 8, the offer includes FTP 8 and SMTP 8.

In addition to FCP 8, GNSP includes the support of the platforms that connect to the TCP/IP network: in a comprehensive bundle, it supports the TNVIP Server and Ggate applications for the connections of various terminal emulations and GWEB for the automatic conversion of forms to HTML pages as well as for applications using Web 8.

GNSP offers a communication processor, to the state of the art, evolutionary for the future:

• With improved performances, either in transactions per second, in number of simultaneous connections or in throughput for the file transfers,
• Which supports VMF for the connection to several GOSs,
• Which supports the connection to DSA or TCP/IP GCOS 8 applications using only a TCP/IP network (using RFC1006 for the DSA accesses) allowing to simplify the network infrastructure,
• Which integrates communication gateways for the connection of workstations to GCOS via TNVIP or Glink emulators directly without intermediate gateways,
• Which allows to connect end users via their browser for the WEB8 applications or for the automatic face-lifting of the GCOS 8 forms toward HTML pages,
• Which reconnects, via RFC1006, the servers and communication gateways used previously in connection to FCP 8 (e.g : MainWay),
• Which runs on an open platform bringing the capability to evolve easily (e.g. for new network interfaces) and to allow usage of standards from the open world (security, directories ..).
