Abstract: An apparatus is configured to perform a method for user equipment (UE) offloading. The method includes receiving, at a network controller, a measurement report from a UE, the measurement report radio link measurement quantities of a serving cell and one or more candidate serving cells, the measurement quantities measured after interference cancellation or suppression. The method also includes, based in part on the measurement report from the UE, determining whether to offload the UE to a second cell among the one or more candidate serving cells.

Abstract: A method for establishing end-to-end tunnels extending across multiple domains using a network element. The method includes receiving a request from a customer controller to implement a virtual network (VN) created by the customer controller, wherein the VN identifies the end-to-end tunnels extending across the multiple domains, mapping the VN to available resources based on network constraints in response to the request, and transmitting, after the VN has been mapped, a message to a network controller managing one of the domains that includes a network path used to form a portion of one of the end-to-end tunnels, wherein the message includes an association object having a Type-Length-Value (TLV) field containing a virtual network identifier binding the network path to the VN.

Abstract: A system and method for improved online transaction processing (OLTP) in a sharded database is provided. Overhead associated with a global transaction manager is reduced and scalability improved by determining whether incoming queries are single-shard transactions or multi-shard transactions. For multi-shard transactions, a distributed transaction ID (DXID) is requested from the GTM, and then forwarded with the query to one or more data notes. For single-shard transactions, the query is sent to a data node without requesting a DXID from the GTM.

Abstract: A data center interconnection (DCI) network may comprise a data center controller (DCC) managing a plurality of data centers (DCs) interconnected by a provider network managed by a network provider controller (NPC). The provider network may be an OpenFlow based software defined networking (SDN) transport network. The DCC may initiate a virtual network service (VNS) negotiation with the NPC to connect the DCs and may specify a network abstraction granularity level. The NPC may respond by computing paths through the provider network accordingly and providing the DCC with one or more virtual networks (VNs). The DCC may compute virtual paths through the VNs and send virtual network element (VNE) connection setup commands to the DCC. The DCC may convert the VNE connection setup commands into network element (NE) commands to setup connections in NEs of the provider network. The DCC and the NPC may perform fault monitoring, detection, and recovery.

Abstract: A method comprising receiving sensor data from a sensor, obtaining image data from a graphical effects shader based on the sensor data, blending the image data with a plurality of application surfaces to create a blended image, and transmitting the blended image to a display. The method may further comprise blending a color image with the blended image in response to a reduction in ambient light. Also disclosed is a mobile node (MN) comprising a sensor configured to generate sensor data, a display device, and a processor coupled to the sensor and the device display, wherein the processor is configured to receive the sensor data, obtain image data generated by a graphical effects shader based on the sensor data, blend the image data with an application surface associated with a plurality of applications to create a blended image, and transmit the blended image to the display.

Abstract: A solid state drive (SSD) employing a redundant array of independent disks (RAID) scheme includes a flash memory chip, erasable blocks in the flash memory chip, and a flash controller. The erasable blocks are configured to store flash memory pages. The flash controller is operably coupled to the flash memory chip. The flash controller is also configured to organize certain of the flash memory pages into a RAID line group and to write RAID line group membership information to each of the flash memory pages in the RAID line group.

Abstract: An apparatus and method are provided for predictive token validation. In use, a database stores service usage information relating to usage of at least one service hosted by at least one server. Before at least one request for service is received from a user at the at least one server, the service usage information in the database is accessed. Further, based on the service usage information, a token associated with the user is sent to the at least one server for being validated by the at least one server, such that the at least one server allows access to the at least one service by the user, in response to the at least one request for service being received from the user with an identifier that is different from the token.
