The agents are sent as atomic units in an asynchronous manner with the possibility of being queued on delays as happens in a real airport. Not only are the agents alert when queued but they also have the power to route themselves with the added possibilities of semantic or content based routing without reference to the originating framework. Consistency will be maintained by persisting the agents when queued in addition to their ability to perform independent intelligent recovery in the face of failures. We believe that overall communications will be lower thereby reducing the cost of this resource. Simple illustrations of the Agent Airport and the up coming Intelligent Distributed Events and Record Playback Agents are available in Technical Annex in the end of this summary.
Events have the power to react dynamically to subsequent events when queued.
They are dynamically extendible which is necessary for a long lived system such as T NET . Both the agent based communications of the Agent Airport and our agent based Distributed Events system are believed to provide interesting solutions to the communications problem. 4.3 Proxy Agent Data management in a mobile environment raises issues of availability, reaction to changes in the local system, scalability and the separation of mechanism from policy. These mainly concern distributed data using replicas. Availability and consistency of these structures is an application dependent issue.
