Abstract:

A traffic management system for an automatic material handling system (AMHS) divides time into a series of discrete time periods and analyzes a plurality of move requests that are to be executed within a particular time period is disclosed. The traffic management system receives a plurality of move requests from the AMHS and determines how many move requests are to be executed and selects which move requests in particular will be executed in the next time period. The traffic management system prioritizes the selected move requests by analyzing each source node and destination node contained in a move request in conjunction with other node traffic data. The traffic management system analyzes this data to ensure that a move request is not executed if a material transport vehicle would be dispatched to a node having a node traffic balance value that exceeds a predetermined value and a node traffic density value that exceeds a predetermined value.

US Classification:

707102, 707 10

Abstract:

Techniques used in a distributed database system for simplifying copying of objects from one database system in the distributed database system to another and establishing the infrastructure necessary for the distributed system in the database systems. One application of the techniques is setting up a cache database system that has a subset of the objects in another database system and establishing a link for redirecting misses between the cache and the other database system. Also included is the infrastructure in the cache and the other database system for an authentication proxy that establishes sessions in the other database system for users to perform operations that have been redirected as a result of a miss in the cache. The techniques require only that the user supply simple descriptions of some of the objects to be copied; the techniques locate the necessary dependent objects and make objects for the infrastructure. Some of these are descriptions of the infrastructure objects that are copied to the cache and executed there and others are objects that are added directly to the other database system.

707103R, 707100, 707101, 707102, 7071041

Abstract:

A method and system are provided for instantiating objects for participation in information sharing relationships. According to one technique, a copy of an object is made, where the copy includes all changes made prior to a particular point in time, and no changes made after the particular point in time. The copy is used to create a second object. Data that reflects the particular point in time is stored, and subsequently used to determine which changes should be applied to the second object. Data that indicates that the creation time of the second object is stored, and subsequently used to determine which changes should be applied to the original object.

Abstract:

A foreign wireless communication system is operated in a local communication network as if the foreign wireless communication system were a local wireless communication system. A data communication link is established between the wireless communication system and a service provider in a local wireless communication network. An outgoing request for authentication information is communicated from the wireless communication system to a remote administration system over the data communication link. The authentication information is received over the data communication link from the administration system and is transmitted over a signal link from the wireless communication system to the service provider. A requested wireless communication service is received at the wireless communication system based on authentication of the wireless communication system by the service provider using the authentication information.

US Classification:

370235, 370253, 709224

Abstract:

A network monitoring device includes a flow processing element, disposed to receive flow information relating to network flows, and to generate a set of virtual packets, each representing a portion of a network flow. The virtual packets are maintained in a time-sequential order, and read by elements of the network monitoring device to generate information relating to network traffic, such as symptoms affecting the communication network, problems affecting the communication network, and otherwise. The network monitoring device randomly samples virtual packets, with at least one of two effects: (1) flow information from traffic reporting devices that are themselves sampling at differing rates can be equalized, with the effect of standardizing information from all of them; (2) the network monitoring device itself can restrict its attention to a fraction of all virtual packets, with the effect of keeping up with a relatively large number of virtual packets.

US Classification:

709224, 709223, 709225, 709226

Abstract:

A network monitoring system maintains both information regarding historical activity of a network, and information regarding emergent activity of the network. Comparison of historical activity of the network with emergent activity of the network allows the system to determine whether network activity is changing over time. The network monitoring system maintains data structures representing a p. d. f. for observable values of network parameters. Recent activity of the network can be compared with both the p. d. f. for historical activity and for emergent activity to aid in determining whether that recent activity is within the realm of normal, and whether network activity is changing over time. The network monitoring system adjusts that information regarding historical activity of a network in response to emergent activity of that network. The network monitoring device determines information regarding time-dependent activity of that network in response to spectral analysis regarding historical activity of that network.

US Classification:

370338000, 370352000

Abstract:

A method for processing an multi-country international phone call, free from an international toll charge, using a voice over IP (VoIP) call from a first mobile handset to a second handset. The method includes transferring destination number information associated with a destination number within a first country code from the first mobile handset to a data network, which is coupled to a world wide network of computers. In a preferred embodiment, the handset is coupled via cellular network through a data network to the world wide network of computers. The method includes transferring caller number information associated with a caller number within a second country code from the first mobile handset to the data network. In a preferred embodiment, the second country code is different from the second country code. The method includes receiving the destination information at a call server process, which is coupled to the world wide network of computers. The method also includes receiving the caller number information at the call server process. The method initiates a first VoIP phone call using the caller number information from the server process to the first mobile handset. The method initiates a second VoIP phone call using the destination number information from the server process to the second handset. The method also connects the first VoIP phone call to the first mobile handset to the second VoIP phone call to the second handset through the server process. The method also includes exchanging voice information between the first mobile handset and the second handset free from an international toll charge.
