Abstract

A method and system are disclosed in a computer network for efficiently permitting code applets to communicate with other code applets remotely located within the computer network, wherein the computer network includes local network sites linked to remote network sites. Initially a communications link is established at each local network site, wherein the communications link permits code applets to communicate with one another. The communications link is composed of an InfoBus for inter-applet communication. The communications links are then interconnected, such that during a subsequent processing of the code applet at a local network site, the code applet may communicate with a code applet maintained at a remote network site, thereby forming a distributed communications link throughout the computer network. Gateways are also established at each local and remote network site within the communications network, wherein the gateways permit code applets maintained at local network sites to communicate with code applets maintained at other network sites. Each gateway established at each local network site is linked with each communications link installed at each local network site.

Claims

1. A method in a computer network for efficiently permitting code applets to communicate with other code applets remotely located within said computer network, wherein said computer network includes local network sites linked to remote network sites, said method comprising the steps of:

installing at each local network site within said computer network, a communications link that permits code applets to communicate with one another; and

interconnecting said communications links within said computer network by establishing gateways at each local and remote network site within said communications network wherein messages at any gateway are reproduced at all gateways within a said communications network, such that during a subsequent processing of a code applet at a local network site, said code applet may communicate with a code applet maintained at a remote network site, thereby forming a distributed communications link throughout said computer network.

2. The method of claim 1 further comprising the steps of:

processing a code applet at said local network site; and

generating a communications event, in response to processing said code applet at said local network site, such that said communications event may be generated at either the local network site or remote network site.

3. The method of claim 2 further comprising the steps of:

transferring said code applet from a remote network site to a local network site, in response to connecting said local network site to said remote network site; and

storing said code applet within a memory cache, in response to transferring said code applet from said remote network site to said local network site.

4. The method of claim 3 further comprising the steps of:

prompting a user to customize a particular gateway, in response to transferring said code applet from said, remote network site to said local network site; and

customizing said particular gateway, in response to user input.

5. The method of claim 4 further comprising the step of switching to a communications link installed at another network site.

6. A system in a computer network for efficiently permitting code applets to communicate with other code applets remotely located within said computer network, wherein said computer network includes local network sites linked to remote network sites, said system comprising:

means for installing at each local network site within said computer network, a communications link that permits code applets to communicate with one another; and

means for interconnecting said communications links within said computer network, by establishing gateways at each local and remote network site within said communications network wherein messages at any gateway are reproduced at all gateways within said communications network, such that during a subsequent processing of a code applet at a local network site, said code applets may communicate with a code applet maintained at a remote network site, thereby forming a distributed communications link throughout said computer network.

7. The system of claim 6 further comprising:

means for processing a code applet at said local network site; and

means for generating a communications event, in response to processing said code applet at said local network site, such that said communications event may be generated at either the local network site or remote network site.

8. The system of claim 7 further comprising:

means for transferring said code applet from a remote network site to a local network site, in response to connecting said local network site to said remote network site; and

means for storing said code applet within a memory cache, in response to transferring said code applet from said remote network site to said local network site.

9. The system of claim 8 further comprising:

means for prompting a user to customize a particular gateway, in response to transferring said code applet from said remote network site to said local network site; and

means for customizing said particular gateway, in response to user input.

10. The system of claim 9 further comprising:

means for switching to a communications link installed at another network site.

11. A program product residing in computer memory within a computer in a computer network for efficiently permitting code applets to communicate with other code applets remotely located within said computer network, wherein said computer network includes local network sites linked to remote network sites, said program product comprising:

instruction means residing in a computer for installing at each local network site within said computer network, a communications link that permits code applets to communicate with one another; and

instruction means residing in a computer for interconnecting said communications links within said computer network by establishing gateways at each local and remote network site within said communications network wherein messages at any gateway are reproduced at all gateways within said communications network, such that during a subsequent processing of a code applet at a local network site, said code applet may communicate with a code applet maintained at a remote network site, thereby forming a distributed communications link throughout said computer network.

12. The program product of claim 11 further comprising:

instruction means residing in a computer for processing a code applet at said local network site; and

instruction means residing in a computer for generating a communications event, in response to processing said code applet at said local network site, such that said communications event may be generated at either the local network site or remote network site.

13. The program product of claim 12 further comprising:

instruction means residing in a computer for transferring said code applet from a remote network site to a local network site, in response to connecting said local network site to said remote network site; and

instruction means residing in a computer for storing said code applet within a memory cache, in response to transferring said code applet from said remote network site to said local network site.

14. The program product of claim 13 further comprising:

instruction means residing in a computer for prompting a user to customize a particular gateway, in response to transferring said code applet from said remote network site to said local network site; and

instruction means residing in a computer for customizing said particular gateway, in response to user input.

15. The program product of claim 14 further comprising:

instruction means residing in a computer for switching to a communications link installed at another network site.

16. The program product of claim 15 wherein each of said instruction means further comprises signal bearing media.

17. The program product of claim 16 wherein said signal bearing media further comprises transmission media.

18. The program product of claim 16 wherein said signal bearing media further comprises recordable media.
