20130132498Content Distribution Through Blind-Cache Instantiation - A slave resource router may receive a client request. The slave resource router may be the nearest representation of an Anycast IP address in a network to a client sending the client request in the network. The slave resource router may then determine that the slave resource router has been authorized to cache content for a delivery service corresponding to the client request. Next, the slave resource router may determine that content corresponding to the client request is cached locally in a blind cache. Then the slave resource router may provide the client with the content from the blind cache.05-23-2013
20130132502SELECTION OF SYNCHRONIZATION STATIONS IN A PEER-TO-PEER NETWORK ENVIRONMENT - A system, apparatus and method for selecting one or more synchronization stations, or masters, in a peer-to-peer communication environment. Synchronization (or sync) stations broadcast periodic synchronization frames to advertise future availability windows, during which devices rendezvous for discovery and communication. Devices that can act as sync stations advertise preference values, which indicate their preference or suitability for the role. All devices execute the same algorithm to sort the preference values and identify a root sync station and any number of branch sync stations; leaf devices synchronize with the root or a branch sync station. This passive synchronization scheme allows individual devices to conserve power, because they need not actively discover other devices and services, and can power off their radios for periods of time without sacrificing discoverability. Synchronization and peer-to-peer communication as provided herein coexist with other device demands, such as Bluetooth® operations and infrastructure-based communications.05-23-2013
20130132501SYNCHRONIZATION OF DEVICES IN A PEER-TO-PEER NETWORK ENVIRONMENT - A system, apparatus and method for synchronizing devices in a peer-to-peer communication environment. Devices select a master to facilitate their synchronization, and rendezvous according to a schedule of availability windows broadcast by the master. Devices may attend some or all of the availability windows, during which they may send and receive unicast and/or multicast messages. Individual devices conserve power by being automatically synchronized instead of having to individually discover other devices and services, and can power off their radios without sacrificing discoverability. Synchronization and peer-to-peer communication as provided herein coexists with other device demands, such as Bluetooth® operations, infrastructure-based communications and so on.05-23-2013

20120284354METHOD AND SYSTEM FOR DYNAMICALLY CREATING AND SERVICING MASTER-SLAVE PAIRS WITHIN AND ACROSS SWITCH FABRICS OF A PORTABLE COMPUTING DEVICE - A method and system for dynamically creating and servicing master-slave pairs within and across switch fabrics of a portable computing device (“PCD”) are described. The system and method includes receiving a client request comprising a master-slave pair and conducting a search for a slave corresponding to the master-slave pair. A route for communications within and across switch fabrics is created and that corresponds to the master-slave pair. One or more handles or arrays may be stored in a memory device that correspond to the created route. Next, bandwidth across the route may be set. After the bandwidth across the newly created route is set, the client request originating the master-slave pair may be serviced using the created route. Conducting the search for the slave may include comparing unique identifiers assigned to each slave in a master-slave hierarchy. The search within and across switch fabrics may also include reviewing a fabric route check table for slaves that can be interrogated within a switch fabric.11-08-2012

20130185373GROUP FORMATION WITHIN A SYNCHRONIZED HIERARCHY OF PEER-TO-PEER DEVICES - A system, apparatus and method for organizing devices in a peer-to-peer communication environment. A number of devices synchronize among themselves and select masters (or synchronization stations) to organize the devices into a hierarchy. Master devices have associated preference values reflecting their preference or suitability to be a master device, and broadcast synchronization frames to keep devices synchronized. When multiple devices in one or more hierarchies execute a common application or service, they form a private group to exchange or share data (e.g., play a game, transfer a file). All devices in the hierarchy maintain and advertise a public or default identifier of the hierarchy, and all devices in the private group maintain and advertise a private identifier specific to the group. Members of the group synchronize under a top group master (or root sync station), which synchronizes with a master that is part of the hierarchy.07-18-2013
