Abstract: A system and method of managing a network provides for distributed storage and retrieval. In one embodiment, information such as a text message is stored by calculating an actual destination node based on a subscriber identifier and a current addressing function, which corresponds to a current topology of a network. The message is sent to the actual destination node for storage. Messages can be retrieved by calculating a plurality of destination nodes based on a subscriber identifier and a plurality of addressing functions, where each addressing corresponds to a topology of the network at a particular moment in time. In one embodiment, the addressing functions are hash functions.

Abstract: Systems and methods of processing incoming data provide for receiving incoming data and determining whether to employ stateless routing of the incoming data based on one or more destination hosts associated with the incoming data. In one approach, stateless routing involves storing the incoming data only in volatile memory and withholding confirmation of receipt of the incoming data until confirmation of delivery is received from either the destination host or a downstream router. The determination as to whether stateless routing should be employed can take into consideration historical data for the destination host as well as control data. The determination can also be based on the number of destination hosts.

Abstract: A handheld device user may engage in motion-based communication with a target user over a wireless network. In one embodiment, a plurality of movements are associated with a plurality of corresponding communications. Upon detection of a handheld device motion, a determination may be made as to whether the handheld device motion corresponds to one of the known movements. If so, one of the plurality of corresponding communications may be sent to the target user over the wireless network.

Abstract: A process and implementing computer system (13) for updating circuit representations in a hierarchical Directed Acyclic Graph (DAG) format (400-410) based upon changes made to the primitive components of the circuit in a flat representation (201-213) includes performing a depth first search (505) on the hierarchical representation of the circuit beginning at the root level (501) for a given path. At each lower level, each child instance is visited (505) and if there is any change in any attribute between the hierarchical and flat representations (509), the component in the hierarchical representation which needs to be changed is copied (807) and connected to the children components of the original hierarchical representation. Changes in the attributes of the children components are made in the copied component (809).
