  • Patent number: 6560635
    Abstract: A system and method for locally caching remote query replies in an electronic network comprises a local registry that performs a local query for a local software module to locate a target software element for a network messaging process. If the local query is unsuccessful, the local registry responsively creates a remote query based on the unsuccessful local query, and then broadcasts the remote query to remote registries across the electronic network. The local registry then evaluates the remote query replies and stores a remote element registration into a local cache for each successful remote query reply. The local software module may then locally identify those remote target software elements with which the local software module frequently communicates, to facilitate efficient network messaging processes.

  • Patent number: 6542474
    Abstract: A system and method for incrementally updating remote element lists in an electronic network comprises a communication media manager that notifies an event manager whenever the electronic network is altered by a network event that adds or removes devices. The event manager responsively notifies a device-control module manager that is subscribed for notification when a network event occurs. The device-control module manager responsively generates a network analysis to various software elements in the electronic network to indicate either the addition or removal of a device on the network. A local registry element may then receive the network analysis and responsively generate an updated remote registry list, in accordance with the present invention.
