Abstract: A content caching and delivering apparatus transmits and receives communication signals in between a content delivering apparatus delivering content on a telecommunications network and communication terminals. A content storage stores content delivered by the content caching and delivering apparatus. A delivery controller receives a content delivery request for the content stored in the content storage, and maps information on the position of the requested content to information on the content for each terminal and manages the mapping. The delivery controller delivers the requested content to the communication terminal.

Abstract: A system and method of operating equipment and services to allow enhanced global transport of IP packets is presented. A global virtual network with guaranteed capacity is used to transport said IP packets. A number of application-specific forwarding devices are deployed to detect and forward selected traffic types to the virtual network. The application-specific selective forwarding devices can be implemented based on the IP packets analysis, or by deploying enhanced control protocols like SIP/H.323.

Abstract: A reliable communication protocol RUDP is provided to transfer data between two systems connected in a network. Working over the unreliable UDP transport layer protocol, the RUDP protocol adds an acknowledging mechanism to otherwise unreliable UDP packets. Contrary to the TCP transport layer protocol, which establishes a connection before any data transfer, the RUDP is used to transfer short amounts of information or messages, so a connectionless communication is used. In a connectionless context the complexity of the encoding-decoding algorithm and the amount of memory consumed by the protocol is reduced. Such characteristics makes the RUDP protocol suitable for its implementation in systems with limited memory and speed, like low processing power 8-bit microcontrollers. Furthermore, by programming the RUDP protocol over the UDP protocol, its implementation in a personal computer can be made with common programming tools.

Abstract: Some embodiments provide a capacity exchange whereby capacity from different content delivery networks (CDNs) can be bought, sold, and traded. The capacity exchange is part of an “Open CDN” platform. The Open CDN platform federates the independent operation of CDNs and other operators of and service providers to distributed platforms participating in the Open CDN platform so that each participant can (1) dynamically scale its capacity without incurring additional infrastructure costs, (2) expand its service into previously untapped geographic regions without physically establishing points of presence (POPs) at those geographic regions, and (3) reduce sunk costs associated with unused capacity of already deployed infrastructure by selling that unused capacity to other participants that are in need of additional capacity.

Abstract: A system and method for communicating with power tools using a universal protocol. The universal protocol may be implemented using a universal core module that is installed across a variety of power tools and other devices to enable communications therewith. Communications to and from the power tools are translated to a universal protocol once received. The translated communications are handled by the universal core module of a particular tool according to a set of rules. In response, the universal core module outputs communications according to the universal protocol and the set of rules, which may be translated to another protocol for receipt by components of the tool or an external device. The communications may be used, for example, to obtain tool performance data from the tools and to provide firmware updates.

The one or more computer processors determine a group of trusted network connected endpoints. The one or more computer processors determine whether the requested resource exists in the group of trusted network connected endpoints. Responsive to determining the requested resource exists in the group of trusted network connected endpoints, the one or more computer processors download the requested resource from at least one of the trusted network connected endpoints.

Abstract: A method and apparatus for providing domainless service selection (DLSS) are described. According to one embodiment of the invention, there is a service selection network element used to provide access of computing devices to a set of one or more services provided by a set of one or more providers. In addition, a web portal allows subscribers to log in and/or select/switch between the services and providers. Responsive to such action by a given subscriber, the web portal causes a record of that subscriber to be altered to reflect the action and causes the service selection network element to attempt to connect the subscriber accordingly. According to certain embodiments of the invention, subscribers' domainless user identifiers are merged by the service selection network element with domain names (stored in a database) of services/providers to form network addresses (e.g., Internet addresses).

Abstract: A method for distributing information in a network includes independently selecting and sending segments of N files to a plurality of terminals through a network. One or more of the selected segments except a first segment are sent to a first number of the K terminals, and one or more of the selected segments except a second segment are sent to a second number of the K terminals. A first logical combination of segments is then generated and sent to the terminals. By logically combining the first logical combination with previously sent files, a new file not previously received may be recovered.

Abstract: Mechanisms are provided for instigating the sending of an acknowledgement response from a host system. A buffer of a data processing system is monitored to determine if there is a data transfer pending in the buffer. In response to a determination that there are no data transfers pending in the buffer, a determination is made as to whether there is an outstanding data transfer, on a corresponding network connection with the host system, for which an acknowledgement response has not been received from the host system. In response to a determination that there is an outstanding data transfer for which an acknowledgement response has not been received, an acknowledgement instigation message is sent to the host system to instigate the host system sending an acknowledgement response for the outstanding data transfer.

Abstract: Techniques for implementing a load balanced server system are described which may be used for effecting electronic commerce over a data network. The system comprises a load balancing system and a plurality of servers in communication with the load balancing system. Each of the plurality of servers may include a respective data cache for storing state information relating to client session transactions conducted between the server and a particular client. The load balancing system can be configured to select, using a load balancing protocol, an available first server from the plurality of servers to process an initial packet received from a source device such as, for example, a client machine of a customer. The load balancing system can also configured to route subsequent packets received from the source device to the first server. Before generating its response, the first server may verify that the state information relating to a specific client session stored in the data cache is up-to-date.
