International Classification:

G06F 15/173

US Classification:

709223, 709224

Abstract:

A framework is disclosed which enables a management system to manage completely different type of network elements (NEs) running different versions of their embedded software by introducing generic operational interfaces, generic data interfaces, information descriptors and self adaptive control mechanism. This Management system framework consists of mainly two parts a) core application and b) element-dependent components and c) a set of generic interfaces. When the management system is launched, it executes the core application. The core application comprises of network element independent version independent generic functionalities that can be used to interact with a variety of network elements and a dynamic control mechanism to make selection and placement of pluggable components at appropriate time and place during execution. After the core application is executed, whenever a need to manage one or more network elements, self adaptive control mechanism will take decision based on information descriptor of that target NE and NE type dependent version dependent modules are incorporated or “plugged in” with core application to produce an overall management mechanism to manage that target NE.

US Classification:

709231

Abstract:

Techniques are provided herein for failover streaming mechanisms. At a first device (e. g. , a content router device) that is configured to interface with a plurality of streaming servers for real-time protocol packet streams, communications are configured with a client device and a first of the plurality of streaming servers associated with a streaming session from the first streaming server to the client device so that the first device receives client session control and session feedback messages associated with the streaming session and so that a packet stream associated with the streaming session transmitted by the first streaming server to the client device does not pass through the first device. The first device stores session state information comprising an address of the client device, streaming session identification information and data representing a current state of the streaming session at the client device derived from the client session control and session feedback messages. Upon detecting a failure of the first streaming server, the first device selects a second of the plurality of streaming servers for serving the streaming session previously served by the first streaming server, and then initiates a streaming session from the second streaming server to the client device in order to continue from a state of the streaming session previously served by the first streaming server prior to the failure without any indication at the client device of the switching from the first streaming server to the second streaming server.

US Classification:

Abstract:

A streaming file is constructed with a file header section that includes a file header object, a media data file descriptor, and an index descriptor. A hinting index section includes a first level hinting index with a linear organization corresponding to timing tick key values. A second level hinting index has a non-sequential organization corresponding to such timing tick key values. A special mark in the second level hinting index indicates that the first level hinting index must be consulted for a next timing tick key value. Such mark is positioned in the last of a sequential run of timing tick key values associated with its entries. A data section that can be put in a separate file, and it accepts media data blocks associated in sequential runs of timing tick key values as its entries. Thus hinting is provided for a non-sequential media data file.

Abstract:

An electronic device may have a housing in which an antenna is mounted. An antenna window may be mounted in the housing to allow radio-frequency signals to be transmitted from the antenna and to allow the antenna to receive radio-frequency signals. Near-field radiation limits may be satisfied by reducing transmit power when an external object is detected in the vicinity of the dielectric antenna window and the antenna. A capacitive proximity sensor may be used in detecting external objects in the vicinity of the antenna. The proximity sensor and the antenna may be formed using integral antenna resonating element and proximity sensor capacitor electrode structures. These structures may be formed from identical first and second patterned conductive layers on opposing sides of a dielectric substrate. A transceiver and proximity sensor may be coupled to the structures through respective high-pass and low-pass circuits.
