A method and system for streaming software applications to a client uses an application server having a library with the application files stored therein. A streaming manager is configured to send the application files to a client as a plurality of streamlets, each streamlet corresponding to a particular data block in a respective application file. A streaming prediction engine is provided to identify at least one streamlet which is predicted to be most appropriate to send to a given client at a particular time in accordance with a prediction model reflecting the manner in which the application files are loaded and used by the application. In the preferred implementation, the application files are preprocessed and stored as a set of compressed streamlets, each of which corresponds to a file data block having a size equal to a code page size, such as 4k, used during file reads by an operating system expected to be present on a client system. In addition, the server is configured to send a startup block to a new streaming client containing a file structure specification of the application files and a set of streamlets comprising at least those streamlets containing the portions of the application required to enable execution of the application to be initiated.

In a data transfer scheme using a caching technique and/or a compression technique which is capable of reducing the network load of a network connecting between data transfer devices, correspondences between data and their names are registered at the data transfer devices and the corresponding names are transferred, instead of transferring the data, for those data for which the correspondences are registered, so that it is possible to reduce the amount of transfer data among the data transfer devices. Even when the name corresponding to the data is not registered so that it is impossible to transfer the corresponding name instead of transferring the data, it is possible to reduce the amount of transfer data among the data transfer devices by transferring the compressed data in which this data is expressed in a compressed form by utilizing the name corresponding to the registered reference data.

A CP participated contents delivery system and method, and a CDN DNS server of the system are provided. When a client detects an embedded object while parsing a page received from a web server, the client inquires of a local DNS server about the IP address of a server storing the object. The local DNS server receives the inquiry of the client and inquires of a CDN DNS server about the IP address of the server storing the object. The CDN DNS server selects a server located in proximity to the client from a host server of a CDN provider, which stores the object, and the web server. The selected server transmits the object to the client. Accordingly, the client can rapidly receive the object and a contents provider can promote qualitative contents providing service improvement.

In a data transfer scheme using a caching technique and/or a compression technique which is capable of reducing the network load of a network connecting between data transfer devices, correspondences between data and their names are registered at the data transfer devices and the corresponding names are transferred, instead of transferring the data, for those data for which the correspondences are registered, so that it is possible to reduce the amount of transfer data among the data transfer devices. Server side data transfer devices and client side data transfer devices can be provided in multiple-to-one, one-to-multiple, or multiple-to-multiple manners.

Receiving a connection establishment request message sent by a user equipment; establishing a signaling connection with the user equipment according to the connection establishment request message; and transmitting a user plane IP data packet through the signaling connection. After a signaling connection is established between a UE in an idle state and a mobility management device, an uplink user plane IP data packet or a downlink user plane IP data packet, is directly transmitted between the UE and the network side through the signaling connection, with no need to specifically establish (recover) an RAB between the UE and an S-GW, which can save the signaling overhead, thus reducing the network load and lowering the operating cost of an operator.

In a communication system for a mobile node according to IPv6, a virtual network prefix is configured as a prefix specific to a mobile node in a domain having a plurality of subnetworks. In the domain, a packet is sent to the mobile node by host-based routing on an IPv6 address formed of the virtual network prefix and an interface ID. The communications process with the mobile node which cannot identify a virtual network prefix is performed using a physical network prefix according to IPv6. Accordingly, nodes which can and cannot identify a virtual network prefix can coexist in the domain.

A multi-codec camera system includes a multi-codec camera that acquires video in the form of multiple compression-rate image data and a determination module that selects image data from the multiple compression-rate image data acquired by the multi-codec camera according to a predetermined reference, wherein when a predetermined object is detected from the video acquired by the multi-codec camera, the determination module selects image data at a compression rate according to the size of the detected object.

A system consisting of a plurality of terminals storing image data and an image displaying device which are connected with each other through a network capable of two-way communication has the disadvantage of decreasing in throughput on account of slow image data transfer over the network. According to the present invention, the image displaying device performs two-way communications with each of the terminals by a communication means at the display device side. Also, the image displaying device acquires image data from a relevant terminal while instructing other terminals to suspend transmission by the image data acquisition controlling means, thereby suspending transmission of image data. The image displaying device displays images by the image displaying means based on the thus acquired image data.

Each network device connected to a network broadcasts a cold start trap when activated. A monitoring device captures this trap and checks whether the trap is an SNMP packet. If the trap is an SNMP packet, the monitoring device extracts the address from the received packet and registers the address in a directory server, or requests the status of a device as a transmission source and registers the received status in the directory server.

Computer-assisted procedure (501/502) to communicate data in a transportation system (90) that physically transports objects (800) from first to second locations (10, 20). The objects (800) have write/read memory tags (300). Prior to communicating data is separated into meta-data M and content-data C. Communicated are: C on the tags (300), M through a computer network, and type-data T (representing M) on the tags. System computers (901, 902, 900) perform complementary methods for forwarding (501) and retrieving (502). To forward (501) data from the first location (10), a first computer (901) queries (510) an exchange computer (901) with M for T according to a predefined T-to-M table, writes T to the tags (300), and writes C to the tags (300). To retrieve (502) data at the second location (20) where the objects arrive, a second computer (902) reads T from the (300), queries (550) the exchange computer (900) with T for M according to the same table, and reads (560) C from the tags (300).

Provided are a method and a device of a host with IPv4 application for performing communication. The method of the host with IPv4 application for performing data communication includes the following steps: the IPv4 application generates an IPv4 packet sent to a communication end; when confirming the type of the network the host is located in is an IPv6 network, the host transforms the IPv4 packet head of the IPv4 packet to an IPv6 packet header, and sends it to the communication end via the IPv6 network. With this invention, it can be accomplished that according to the type of the network the host is located in, the host with IPv4 application communicates with a communication end; the processing load of the system is lightened; the probability that invalidation occurs at a single node is reduced; the smooth migration and transition from original IPv4 application to IPv6 system are facilitated.

A system for delivering content at varying qualities from a server to multiple client across a network has a server side converter and a client side converter. The server side converter makes unicast requests to a server for representations of content and converts these to multiple representations to be delivered as multicast streams. The client side converter receives a request for content from clients, determines a representation of content to obtain and subscribes to an appropriate multicast stream. The client side then converts the multicast stream back into segments available to a client by unicast request. In this way, data is delivered efficiently across a network from a server side to a client side whilst maintaining compatibility that client devices can issue traditional unicast requests.
