Embodiments of a system and method for using mobile agents for collaborative content control in peer-to-peer networks. A peer may launch a mobile agent including an itinerary of peers to be visited and indications of one or more documents that the peers are collaboratively editing. The mobile agent may visit peers indicated by the itinerary to collect version information for the document(s).

The initiating peer may send the most recent version information to peers that added version update requests to the payload.

A billing system for a telecommunications network uses a monitoring software agent to monitor messages, indicative of individual calls on the network, passing between a service switching point and a service control point. Call record information is extracted and is stored in a local call record database. Information from each call record database is then passed on to a central database, using updating mobile agents, the central database being accessible to such agents and report building agents which can extract billing information as requested by an operator. By monitoring the messages as they pass, the system can provide real time billing information without needing to poll the switch at the service switching point.

The instruction instructs the secondary server node to provide the service. The technique further includes providing, in response to the instruction, the service from the secondary server node to the client node.
