Abstract

Intelligent mobile agents are transmitted to computers at remote sites over a network having a relatively limited bandwidth. In order to provide the mobile agents with extended capabilities, yet to allow them to access information in near-real-time, the intelligent mobile agents dock with docking systems at the network nodes. The docking systems respond to the presence of the mobile agents, and provide extended capabilities to the agent. The extended capabilities, in turn, are made available to the various network nodes at which the agents may dock by loading from portable data storage media, or preferably by occasional loading from the network at off-peak times.

Claims

1. A distributed communication network, comprising:

a plurality of computers;

communication means for coupling said computers together for communications therebetween;

standardized computer network software associated with each of said computers, for providing basic network communications between said computers by way of said communication means;

mobile agent generating means located at at least one of said computers of said network, for generating mobile agents for performing a desired function, and for transmitting said mobile agents over said communication means, the dimensions of each of said mobile agent being generally related to its capability, whereby highly capable mobile agents may not be usable because of network bandwidth limitations;

mobile agent docking means located at each computer of said network which is capable of coacting with said mobile agents, for rendering said agents active at said coacting computer; and

mobile agent capability expanding means located at at least one of said coacting computers of said network, for extending at least one capability of a mobile agent received at said one of said coacting computers of said network, whereby the capability of said mobile agent may be enhanced.

2. A communication network according to claim 1, wherein one of said communication mobile agent generating means and one of said mobile agent docking means are located together at at least some of said computers of said network.

3. A method for operating a communication system, comprising the steps of:

coupling together a plurality of computers, located at different sites, by way of a network defining a bandwidth, which bandwidth may differ at various locations throughout said network;

communicating among said computers by way of said network, using communication software at each said computer which adheres to a communication standard;

at at least one of said sites, generating mobile agents for performing a desired function, and transmitting said mobile agents onto said network to at least one other computer, whereby said bandwidth of said network may prevent a highly capable mobile agent from being transmitted and received in a suitably short length of time;

preloading into said at least one other computer a mobile agent docking means, which is capable of rendering said mobile agents active at said one of said sites;

preloading into said at least one other computer a mobile agent capability expanding means, for extending at least one capability of a mobile agent received at said one of said computers of said network, whereby the capability of said mobile agent may be enhanced.

4. A method according to claim 3, wherein said preloading of said capability expanding means further comprises the step of:

transmitting said capability expanding means over said network to said one of said computers at a time when the traffic load on said network is low.

5. A method according to claim 3, wherein said preloading of said capability expanding means further comprises the steps of:

physically transporting said capability expanding means to the site of said one of said computers in the form of a recording on a data medium; and

using an appropriate medium reader, reading said recording and transferring said capability expanding means to said one of said computers.
