  • Patent number: 9787792
    Abstract: A network host such as a caching device is disclosed that greatly increases the speed with which a server reads and writes data for clients. The host may include a specialized network interface that not only processes TCP but also parses received network file system headers, identifying those headers within the TCP data stream, separating them from any corresponding network file system data, and providing them separately from that data to the network file system of the host for processing as a batch, all without any interrupt to the host. Similarly, the network file system of the host may communicate directly with the network interface by writing network file system headers directly to a register of the network interface to transmit data.

  • Patent number: 9641422
    Abstract: According to an embodiment, a network device coupled to a local base station at a cell site is configured to automatically create a more optimal route for inter-base station traffic between the local base station and a remote base station. The network device automatically discovers a remote Internet Protocol address of the remote base station used for inter-base station traffic based upon traffic transmitted by the local base station to the network device or traffic transmitted between the local and remote base stations. In response, the network device automatically installs the more optimal route entry in a routing table of the network device, which enables the network device to route inter-base station traffic originated from the local base station and destined to the remote base station using a shorter path through the backhaul network instead of routing the traffic through a mobile core network.

  • Patent number: 9474015
    Abstract: A computing environment containing a mesh network that is adapted to provide a reliable transport mechanism over which services may be delivered. Nodes of the mesh can automatically select routable addresses without conflicts, which allows nodes of the mesh to be accessed, even as the mesh changes through the addition or deletion of nodes. Also, nodes communicate with a protocol that supports service advertisements. These advertisements can identify mesh nodes that supply services, such as file or print servers, for which devices that have not yet connected to the network may be searching. Advertisements can also identify services to be used by nodes in the network, allowing, for example, anode to select a gateway providing a reliable connection to an external network. The mesh network can be used as a transport for communication using protocols, such as TCP/IP, that generally exhibit poor performance when using unreliable transports.

A least significant segment of an address field of an IPv6 header of the packet is generated based on the mapping index, and the IPv6 header is utilized to encapsulate the packet. The IPv4 header is recoverable via the least significant segment of the IPv6 header, so that the IPv4 header may be optionally omitted in transmission of the packet.

  • Patent number: 9131526
    Abstract: Presented are methods and apparatus for decoupling transport and control (T&C) functions from a plurality of eNBs and collecting the T&C functions in a centralized entity for managing the T&C functions for a larger pool of eNBs. An enhanced interface and protocol is defined for allowing the new T&C pool entity to communicate with the eNBs over a shared IP based network. The redistributed functionality provides for optimizing both data compression capabilities and security by compressing data earlier in its transmission path and by encrypting data before it is sent to an eNB.

  • Patent number: 9112779
    Abstract: In a network system in which a large number of terminals that transmit information exist and data extraction is performed via a wide area network, when data filtering is performed by using terminals called entrance nodes, existing in front of the wide area network, efficient operation of the entrance nodes is a goal to achieve. In one implementation, when an entrance node has detected an alteration to a configuration of diverse resources attached to it, it updates management information by communicating with other entrance nodes existing in the neighborhood. In a further implementation, through a query and reply exchange about allocations of filtering and quick response processes to be executed by entrance nodes, reallocating process items, pre-filtering of necessary data, and relaying data between entrance nodes are performed.

  • Patent number: 9055040
    Abstract: Disclosed is a method for securely presenting content in a mobile station. The mobile station may have a smart module, a security agent, and an air interface for communicating with a content provider and with a remote content rights manager. The smart module stores content presentation units and has a proxy content rights manager for when the mobile station is unable to receive secure content keys from the remote content rights manager using the air interface. In the method, content presentation units are transferred from the remote rights manager to the smart module for storage. Secure content keys are requested from the smart module for allowing presentation of content requested while the mobile station is unable to communicate with the remote rights manager. The secure content keys are transferred, based on a stored content presentation unit, from the proxy content rights manager to the security agent for allowing content presentation.
