摘要： Orthogonal Frequency Division Multiplexing (OFDM) is combined with a plurality of transmitting antennas to yield a system that provides space, frequency and time diversity. Specifically, an arrangement is created where a transmitter includes a plurality of antennas that are transmitting simultaneously over the same frequency subbands, and the symbols that are transmitted over each subband, in any given time slot, over the different antennas are encoded to provide diversity. The principles of trellis coding, space-time coding, or any other diversity-producing coding can be applied in this arrangement.

摘要： A system and method for tracking provenance for software use and development includes a developer toolkit program stored in memory media and accessible by a software market place wherein the software marketplace provides a library of software bundles that can be used for software development and modification of the software bundles. The developer toolkit includes a user interface configured to enable software creation of original works and derivative works. The development toolkit further includes a provenance tracker configured to track provenance of the derivative works and original works wherein the provenance tracker makes the derivative work and the provenance of the derivative work available in the software market place. The provenance tracker includes a software bundle identification module configured to identify and verify ownership of the original works and derivative works by associating an owner of the derivative works and original works with features included in portions of the derivative works and original works.

摘要： A method, system and computer program product for managing content distribution in a mobile communications environment. The communications environment includes a core network and a multitude of end-user devices. In one embodiment, the method comprises downloading content from the core network to the end-user devices; and maintaining a map between the end-user devices, the content downloaded to the end-user devices, and the locations of the end-user devices. When a first of the end-user devices requests a specified content, this map and one or more rules are used to identify a second of the end-user devices having the specified content. The first of the end-user devices fetches the specified content from this identified second of the end-user devices. In one embodiment, object location descriptors embedded in the content are rewritten when the content is downloaded to the end-user devices.

摘要： Methods and apparatus are provided for recovering from packet loss in an end-to-end network connection having at least one wireless segment. A packet on a wireless segment of an end-to-end network connection is processed by determining whether the packet comprises one or more of a lost packet and a malformed packet; and generating a modified packet for an application associated with the packet to replace one or more of the lost packet and the malformed packet if the application is substantially tolerant to one or more of lost and malformed data. The modified packet comprises, for example, a non-original packet and/or a corrected packet. Link layer information or information from a deep packet inspection can be used to determine whether the packet comprises a lost packet or a malformed packet.

摘要： Middlebox systems that can enter a connection include a monitoring module to monitor information in a connection between a client and a server, a processor to determine that the connection is idle, a table configured to create a first entry for the client and a second entry for the server, where the entries are initialized using information gathered by the monitoring module, and a control module to redirect the connection between the client and server to the middlebox. Middlebox systems that can exit a connection include a processor to determine a mismatch between sequence numbers in a first connection to a client device and in a second connection to a server device. A network control module delays acknowledgment signals from the middlebox on a connection to decrease the degree of mismatch and establishes a direct connection between the client device and the server device when mismatch is zero.
