Abstract: A method for managing contents shared by a Social Network Service (SNS), executed by a cloud server which is associated with an account of the SNS. It is detected whether a first content has been newly uploaded to the SNS or whether a metadata related to the first content previously uploaded to the SNS has been newly added. A second content corresponding to the first content is searched. The cloud storage is updated by linking context information related to the first content to the second content corresponding to the first content. The cloud server interworks with an account of the SNS of each user's individual to link context information of content shared on the SNS with the content stored in the personal cloud storage, thereby enabling easier update of the cloud storage. A user may easily search for desired contents using the context information.

Abstract: In a synchronization system including a local terminal, latest metadata of a file in a local storage and latest metadata of a file in the server storage are managed in a first tree database, which is a virtual database in a local terminal, and each of the local terminals is allowed to upload or download a changed file on the basis of the metadata in the first tree database so that a conflict that may occur due to multiple users simultaneously changing files can be minimized.

Abstract: A network device (ND) includes a first interface controller operable to transfer data between the ND and a host processing unit (host), a second interface controller operable to transfer data between the ND and the host, a network interface configured to interface the ND with a network, and a control unit operable to: receive incoming data from the network, process the incoming data, and transmit the processed incoming data to the host through the second interface controller; or, receive outgoing data from the host through the second interface controller, process the received outgoing data, and transmit the processed outgoing data to the network. The first interface controller, the control unit, and the network interface are together operable to enable the host to transmit and/or receive other data to and/or from the network and the first interface controller. The host and the control unit share a same network address.

Abstract: A Network Device (ND) may be configured to enable secure digital video streaming for HD (high definition) digital video systems over a standard network. The ND may operate in at least one of two modes, a co-processor mode and a stand-alone mode, and may provide at least three high level functions: network interface control (NIC), video streaming offload (VSO), and stand-alone video streaming (SVS). To seamlessly execute the VSO functionality, the ND may be configured to have two network stacks running synchronously on a single network interface having a single network address. The two network stacks may share the data traffic, while the Host network stack may act as a master, and configure the ND network stack to accept only specifically designated traffic, thus offloading some of the data processing to the processor configured in the ND.

Abstract: Active client buffer management methods, systems, and apparatus for transmitting electronic data from a server to a client having a limited receive buffer are disclosed. The receive buffer is managed by determining a consumption rate at the client and adjusting the transmission rate of the server responsive to the determined consumption rate to manage the fill level of the receive buffer.

Abstract: Apparatus and a method for transmitting a plurality of streams of data packets through a computer network assigns queued packets from each of the plurality of data streams to respective slots in scheduling windows such that queued packets from respective ones of the plurality of data streams occupy different slots in respectively different ones of the scheduling windows. The packets are transmitted through the network in the order defined by the scheduling windows.
