摘要： The present invention provides a method and system handling information exchange through networks 102 to 110 for interactive information exchange, especially for interactive Internet based game show. At least one server 120 and a plurality of client machines 130 to 146 are connected through the networks 102 to 110. First, the server 120 receives subscription messages from a subset of said client machines 130 to 146. By receiving the subscription messages from the client machines 130 to 146 the provider of the particular program knows which users want to participate in the program. In response, the server 120 composes a request message offering predetermined response options, whereby corresponding response messages are returned through said networks 102 to 110 in one or more packets. In parallel, packet forwarding rules are set up in said networks 102 to 110 specifying a particular treatment for said returned packets dependent on said predetermined response options. Finally, the server sends the request message to the subset of client machines.

摘要： A method (and apparatus) for determining, in a system including an m-bit time counter, whether an event-occurrence time lies after a predetermined timeout-value, includes reading out of a time-stamp memory a stored time-stamp value, determining the time-difference between the time-stamp value and the event-occurrence time, and determining whether the time-difference is larger than the predetermined timeout-value. The event-occurrence time is represented by a subset of the bits of the m-bit time counter, the subset being determined by a plurality of parameters including any two of a lower bit-position, an upper bit-position, and a subset width. The lower bit-position is dependent on the predetermined timeout-value.

摘要： A method for dynamically programming Field Programmable Gate Arrays (FPGAs) in a coprocessor, the coprocessor coupled to a processor, includes: beginning an execution of an application by the processor; receiving an instruction from the processor to the coprocessor to perform a function for the application; determining that the FPGA in the coprocessor is not programmed with logic for the function; fetching a configuration bit stream for the function; and programming the FPGA with the configuration bit stream. In this manner, the FPGA are programmable “on the fly”, i.e., dynamically during the execution of an application. The hardware acceleration and resource sharing advantages provided by the FPGA can be utilized more often by the application.

摘要： Described is a method and system for processing data packets of a data stream in a communication system. The data packets are processed depending on a feature of the header of a data packet in a faster path or in a slower path. To avoid a disorder by the different processing paths, the fast processed data packets are stored in a memory. The stored fast processed data packets are output after all slowly processed data packets which before the processing were in order before the fast data packets have been put to the output. In this way, the processed data packets are in the same order as prior to the processing.

摘要： A modular approach to the mapping of data in and from a standard SDH/SONET signal is described. A module has interfaces (T0-T8) which allows to connect to it to other of its kind and thereby achieving higher data rates, i.e. access to standard signals of higher levels. By choosing among different interconnection schemes, arrangements comprising a plurality of modules are also able to support concatenated data traffic.

摘要： The dynamic functional behavior of geographically distributed fast packet switching systems, including those which accommodate high-priority circuit switched traffic and low-priority packet switched traffic, are tested in real-time by sending test packets from one or more source nodes through the system to specific destinations that comprise a test packet analyzer. The test packets have the same structure as the data packets, but in their payload portion carry the entire information required to perform the testing. The nature of that test information depends on the characteristics of a set of predefined system errors the verification system is supposed to identify. For detecting errors, the test information would include an input address indicating the source of the test packet, a sequence number defining the order in which the packet should arrive at the destination, time bits relating to the packet length and/or to the expected packet transmission delay, and a cyclic redundancy code which covers the entire contents of the test packet, including its control portion. Each analyzer at a receiving station operates autonomously from the senders and processes all received traffic in real-time; this enables it to recognize all defined system errors, even those occurring with very low probability, at the packet level.

摘要： A method and systems for dynamically distributing packet flows over multiple network processing means and recombining packet flows after processing while keeping packet order even for traffic wherein an individual flow exceeds the performance capabilities of a single network processing means is disclosed. After incoming packets have been analyzed to identify the flow the packets are parts of, the sequenced load balancer of the invention dynamically distributes packets to the connected independent network processors. A balance history is created per flow and updated each time a packet of the flow is received and/or transmitted. Each balance history memorizes, in time order, the identifier of network processor having handled packets of the flow and the associated number of processed packets. Processed packets are then transmitted back to a high-speed link or memorized to be transmitted back to the high-speed link later, depending upon the current status of the balance history.
