Filed:

Dec 8, 2009

Appl. No.:

12/632969

Inventors:

Gustavo de los Reyes - Fair Haven NJ, US
Gang Xu - Piscataway NJ, US

Assignee:

AT&T Intellectual Property I, L.P. - Atlanta GA

International Classification:

G01C 21/34
G08G 1/01

US Classification:

701118, 701410, 4554565

Abstract:

A cellular-based live traffic service that does not require pre-deployment of infrastructure or GPS-enabled devices uses signals provided by cellular devices to determine course resolution localization and tracking information of the cellular devices. Specialized statistical analysis is performed on the course resolution data to infer the fine resolution positions of the cellular devices. In an example embodiment, the localization and tracking information is provided on a map, or the like, to show relative position and/or trajectory of cellular devices.

AT&T Intellectual Property I, L.P. - Reno NV

International Classification:

G06F 21/00

US Classification:

726 22, 713188, 726 24

Abstract:

An edge monitoring approach can be utilized to detect an attack which includes a plurality of relatively low bandwidth attacks, which are aggregated at a victim sub-network. The aggregated low bandwidth attacks can generate a relatively high bandwidth attack including un-solicited data traffic directed to the victim' so that the aggregated attack becomes more detectable at an edge monitor circuit located proximate to the victim. Related systems, devices, and computer program products are also disclosed.

Assignee:

AT&T Intellectual Property I, L.P. - Atlanta GA

International Classification:

G08C 15/00

US Classification:

370252, 709226

Abstract:

A method, network, and computer program product are provided for traffic flow quality of service. A quality of service priority table is received for services defined by a user at the network, and the quality of service priority table includes quality of service levels for the services. Traffic flows are determined to correspond to packets being communicated over the network for the user. The traffic flows are mapped to services. The traffic flows are mapped to the quality of service levels for the services. The quality of service levels are assigned to the traffic flows as assigned quality of service levels corresponding to the services. Each of the traffic flows is routed over the network according to its assigned quality of service levels, respectively.

International Classification:

G06F 15/173

US Classification:

709229, 709226

Abstract:

A method includes sending a first redirect instruction to a first client in response to a first session request received at a service address, and establishing a first session with the first client in response to a second session request received at the first redirect address indicated by the first redirect instruction. Additionally, the method includes determining a first service interval has passed, and sending a second redirect instruction to a second client in response to a third session request received at the service address after the first service interval has passed. The method still further includes establishing a second session with the second client in response to the fourth session request received at the second redirect address indicated by the second redirect instruction after the first service interval has passed, and rejecting the fifth session request received from a third client at the first redirect address after the first service interval has passed.

International Classification:

G06F 21/52

US Classification:

726 3, 726 4, 726 5, 713156, 713165, 713166, 713167, 713168, 711152

Abstract:

A system and method to ensure trustworthiness of a remote service provided by a service provider. The method includes monitoring runtime dependencies invoked during execution of a service transaction associated with the remote service, the service transaction being requested by a service requester. The method further includes determining whether a deviation exists between the runtime dependencies and a trusted list of dependencies associated with the remote service. The method also includes blocking execution of the service transaction based on determining that the deviation between the runtime dependencies and the trusted list of dependencies exists.

726 12

Abstract:

Example methods and apparatus to enhance security in residential networks and residential gateways are disclosed. A disclosed example apparatus includes a transceiver to receive an Internet protocol (IP) packet, a first packet processing module associated with a protected IP address, the first packet processing module to be communicatively coupled to a first network device, a second packet processing module associated with a public IP address, the second packet processing module to be communicatively coupled to a second network device, and a packet diverter to route the received IP packet to the first packet processing module when the IP packet contains the protected IP address and to route the IP packet to the second packet processing module when the IP packet does not contain the protected IP address.
