Abstract: Communication is provided among plural nodes by a network having finite bandwidth between the nodes. The bandwidth may differ for each direction of propagation. Each node includes a processor for processing locally available data, including data derived locally and available through relatively high-bandwidth paths. When processing at any one of the nodes may be improved by incorporating into the data being processed information which is locally available at another node, at least one node is configured to know (a) the directional bandwidth from itself to the remote node(s) of the system, and (b) also to have knowledge, of the relative improvement to be realized at the first node by incorporation of data of the second node into the processing of the first node. The second node selects portions of its own local data for transmission to the first node which yield large improvement and can be transmitted within the available directional bandwidth.

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.

Abstract: Intelligent mobile agents in a distributed network carry information tokens among network nodes. Each token includes compressed information or data, and an indication of the compression algorithm which can decompress the information. At least some of the nodes have at least one decompression algorithm. A copy of a token may be left at a node by an intelligent mobile agent moving through the network. A later-arriving intelligent mobile agent can interrogate the node to determine what information it has in the form of tokens, and can use the token information, or take the token (or a copy) elsewhere.
