Patent number: 7733908Abstract: A cross-layer architecture for a network device having a number of network interfaces is provided. Each of the network interfaces implements a number of low level layers of a protocol stack and includes an associated network based cross-layer agent. The network device also includes an application based cross-layer agent associated with one or more high level protocol stack layers including an application layer. When the application layer desires to form a network connection to another network device, an arbitration agent operates to identify one of the network interfaces for the network connection. The arbitration agent then effects interconnection of the application based cross-layer agent and the network based cross-layer agent of the network interface and interconnection of the high level protocol stack layers and the low level protocol stack layers of the network interface, thereby forming a complete protocol stack having a cross-layer architecture for the network connection.Type: GrantFiled: May 31, 2006Date of Patent: June 8, 2010Assignee: Qurio Holdings, Inc.Inventor: Gregory Morgan Evans

Publication number: 20100100627Abstract: A system and method for bypassing an access point in a wireless Local Area Network (LAN) for direct point-to-point data transfers are provided. A user device in the wireless LAN is equipped with a primary local wireless interface establishing a wireless communication link with an access point of the wireless LAN, a secondary local wireless interface used for direct point-to-point (P2P) file transfers, and a P2P file transfer application. When the P2P application desires to transfer a data file to another user device within the wireless LAN, the user device determines whether the other user device is within a coverage area of the secondary local wireless interface and whether the file transfer meets one or more alternate transfer criterion. If so, the data file is transferred to the other user device via a direct P2P wireless communication link, thereby bypassing the access point of the wireless LAN.Type: ApplicationFiled: December 28, 2009Publication date: April 22, 2010Applicant: QURIO HOLDINGS, INC.Inventor: Gregory Morgan Evans

Publication number: 20080313029Abstract: A system providing late-binding of advertisements to video content and incorporating a push-caching scheme is disclosed. In general, the system includes an advertisement server located at a central location such as a central headend and a number of late-binding systems located at locations such as a number of remote headends. The late-binding systems are connected to the advertisement server via a Wide Area Network (WAN). Each of the late-binding systems is also connected to an associated advertisement cache via a Local Area Network (LAN).

Publication number: 20080306818Abstract: A late-binding multi-client streamer utilizing Remote Direct Memory Access (RDMA) transfers to obtain video and advertisement content is provided. For each client device, the streamer receives a video content selection. In response, the streamer initiates an RDMA transfer of the video content or a segment of the video content from a storage device of a video content server to an associated video buffer and begins streaming the video content from the video buffer to the client device. When an upcoming advertisement slot in the video content is detected, the streamer initiates an RDMA transfer of an advertisement for the ad slot from a storage device associated with an advertisement content server to an associated ad buffer. The streamer then inserts the advertisement from the ad buffer into the ad slot in the video content as the video content is streamed to the client device.Type: ApplicationFiled: June 8, 2007Publication date: December 11, 2008Applicant: QURIO HOLDINGS, INC.Inventors: Gregory Morgan Evans, Alfredo C.
