Abstract

An apparatus for allowing any initiating host to establish communications with any receiving host in a computing network using a Multi-path channel communication protocol. The computing environment also having a gateway device that is electronically connected from one end to at least one initiating host and at the other end to at least one local area network through which a plurality of hosts are connected to the gateway device. The apparatus comprises a special function table for storing all possibly available functions that can be provided for all available commercial communication platforms as well as a memory location accessible by said gateway device for storing said special function table. Determining means then will obtain a list of all supported functions provided by said particularly associated communication platform and through the use of a comparison component provides information about all supported functions in the same special function table. All supported functions are then checked by a monitoring component to modify the function table in case of additions or deletions. In this manner any host can obtain an updated list of all available and supported functions at any time and even select an option from the list if desired.

Claims

1. In a computing network system environment having a gateway device, said gateway device being electrically connected from one end to at least one initiating host and at the other end to at least one local area network through which a plurality of hosts are connected to said gateway device, said computing environment using a Multi-path channel communication protocol, an apparatus for allowing any initiating host to establish communications with any receiving host comprising:

a special function table for storing all possibly available functions that can be provided by all available different communication platforms;

a memory location accessible by said gateway device for storing said special function table;

determining means for obtaining a list of all supported functions provided by a particularly associated communication platform;

comparison component for identifying subset of supported functions present in and entering them in said special function table representing all possible functions;

monitoring component for checking status of all supported functions at preselected intervals to see if additions and deletions are made to said list of supported functions;

means for making alterations and modifications to said special function table as to reflect supported function additions and deletions to said supported functions list;

said special function table also being accessible to all hosts through said gateway device so as to allow all said hosts to obtain an updated list of all supported functions at any one time.

2. The apparatus of claim 1, wherein said communication platform is an integrated platform.

3. The apparatus of claim 1, wherein said communication platform is an open systems adapter platform.

4. The apparatus of claim 3, wherein said computing environment uses Novell IPX communication protocol.

5. The apparatus of claim 4, wherein said functions supported by open system adapter can include RIP function.

6. The apparatus of claim 4, wherein said functions supported by open system adapter can include SAP function(s).

7. The apparatus of claim 4, wherein said functions supported by open system adapter can include Broadcast Filtering.

8. The apparatus of claim 1, wherein said gateway device is uses LAN Channel Station Protocol instead.

9. In a computing network system environment having a gateway device, said gateway device being electronically connected from one end to at least one initiating host and at the other end to at least one local area network through which a plurality of hosts are connected to said gateway device, said computing environment using a Multi-path channel communication protocol, an apparatus for allowing any initiating host to establish communications with any receiving host comprising:

a special function table for storing all possibly available functions that can be provided by all available different communication platforms;

a memory location accessible by said gateway device for storing said special function table;

determining means for obtaining a list of all supported functions provided by a particularly associated communication platform;

comparison component for identifying subset of supported functions present in and entering them in said special function table representing all possible functions;

monitoring component for checking status of all supported functions at preselected intervals to see if additions and deletions are made to said list of supported functions;

means for making alterations and modifications to said special function table as to reflect supported function additions and deletions to said supported functions list;

said special function table also being accessible to all hosts through said gateway device so as to allow all said hosts to obtain an updated list of all supported functions at any one time; and

means for allowing any host to select any one of said functions supported by said communication platform from said list of supported and available functions by issuing a command after viewing said functions available.

10. The apparatus of claim 9, wherein said communication platform is an integrated platform.

11. The apparatus of claim 10, wherein said communication platform is an open systems adapter platform.

12. The apparatus of claim 11, wherein said computing environment uses Novell IPX communication protocol.

13. The apparatus of claim 12, wherein said functions supported by open system adapter can include RIP function.

14. The apparatus of claim 12, wherein said functions supported by open system adapter can include SAP function(s).

15. The apparatus of claim 12, wherein said functions supported by open system adapter can include Broadcast Filtering.

16. The apparatus of claim 9, wherein said gateway device is connected to a plurality of local area networks.

17. The apparatus of claim 16, wherein said local area networks each are of different type and associated with them different and independent communication platforms.

18. The apparatus of claim 9, wherein said gateway device is electrically connected to at least one wide area network.

19. The apparatus of claim 9, wherein said gateway device uses LAN Channel Station Protocol instead.
