摘要:
A hardware device for processing the tasks of an algorithm of the type having a number of processes the execution of some of which depend on binary decisions has a plurality of task units (10, 12, 14), each of which are associated with a task defined as being either one process or one decision or one process together with a following decision. A task interconnection logic block (16) is connected to each task unit for communicating actions from a source task unit to a destination task unit. Each task unit includes a processor (18) for processing the steps of the associated task when a received action requests such a processing. A status manager (20) handles actions coming from other task units and builds actions to be sent to other task units.

The presently disclosed embodiments are directed to representing network performance information using a network map by partitioning a graphical affordance representing a network element in the network map into segmented sections in accordance with a temporal encoding scheme to encode temporal information in the network map. The segmented sections are encoded using a performance encoding scheme to identify a level of performance associated with the segmented sections so that the network map depicts a performance of the network element over time.

A method for validating an electronic payment by a credit/debit card in a transaction system. The method includes registering a purchase of an article by a buyer using a credit/debit card associated with at least one PIN code, checking that the at least one PIN code is associated with the number of said credit/debit card provided by said buyer to said seller terminal, checking, by said electronic payment center, whether or not said at least one PIN code is valid, and one of: after the at least one PIN code is found to be valid, checking, by said electronic payment center, whether the electronic payment center has received a pre-validation from a third party; after the at least one PIN code is found to be valid, contacting a third party via a communication network and requesting that the third party validate the purchase; and after the at least one PIN code is found to be valid, contacting a third party via a communication network and requesting said at least one PIN code from the third party. The third party is a prime owner of the credit/debit card.

摘要:
A method and system as disclosed for use in a virus-free certificate proxy (107, 801), of retrieving from one or a plurality of virus-free certificate authorities (104, 804) a virus-free certificate (200) certifying that a file is virus-free. The method includes the steps of: receiving (1001) virus-free certificate request for a file; selecting a virus-free certificate authority (104, 804) having authority to generate a virus-free certificate (200) for the file; requesting (1003 . . . 1007) the virus-free certificate to the selected virus-free certificate authority (104, 804); receiving (1003 . . . 1007) from the selected virus-free certificate authority the generated virus-free certificate; sending back (1005) in response to the virus-free certificate request the received virus-free certificate.
摘要:
Data transmission system for transmitting packets of data from a source workstation (10) to a destination workstation (18) wherein the packets of data are transmitted over at least an IP network (14) between an ingress node (16) connected to the source workstation and an egress node (20) connected to the destination workstation, wherein each router within the intermediary nodes along the data path from the ingress node to the egress node determines the best route in a routing table defined by the contents of a field contained in each packet of data being received. For this, the router of the ingress node comprises a configuration table which defines the contents of the TOS field in function of information associated with the 4/5 level protocol such as TCP or UDP.
摘要:
Method for transmitting high-priority packets in an IP transmission network based upon the Internet Protocol (IP) wherein low-priority packets or fragments of packets are transmitted between a sender and a receiver and at least a high-priority packet can be transmitted from the sender to the receiver by pre-emption of a low-priority packet or a fragment of packet. The method comprises in the sender, the steps of determining whether a low-priority packet or fragment of packet is being transmitted from the sender to the receiver when a high-priority packet has to be transmitted, setting to 1 a reserved bit within the IP header of the high-priority packet used as a pre-emption indicator if a low-priority packet or fragment of packet is currently transmitted, transmitting the high-priority packet with the pre-emption indicator set to 1 from the sender to the receiver, and resuming the transmission of the low-priority packet or fragment of packet at the end of transmission of the high-priority packet.
摘要:
Automatic speed adaptation system in a Local Area Network (LAN) between a hub (10) including a hub adapter (20, 24, 28) and at least a workstation (12, 14, 16) including a workstation adapter (18, 22, 26) for exchanging data over a link connected between the hub adapter and the workstation adapter at a rate based on a frequency which is inversely proportional to the length of the link. Each adapter comprises a clock generator for generating a clock having a frequency between F1 and F2 and processing means for transmitting at least a check frame from the hub adapter to the workstation adapter at a rate based on a frequency VCLK generated by the clock generator under the control of the processing means and selected as being the frequency corresponding to the length of the link, and for transmitting an acknowledge frame from the workstation adapter to the hub adapter thereby ascertaining that the selected frequency is the right frequency resulting in the best quality of transmission.
摘要:
Security system for preventing a personal computer (PC) including at least a location in the PC adapted to receive a PCMCIA card from being used by unauthorized people including an extractable card having a connection adapted to insert the extractable card into the location for receiving a PCMCIA card. Further included are a processor and a wireless transceiver for remotely transmitting alarm information relative to the PC. Still further included is a program stored in the memory of the PC for communicating with the processor in order to activate selected security functions.
摘要:
A device for parallel processing of subtrees within a binary tree for searching for the tree leaf matching a search key. The search is performed at each node by applying a recursive function associated with each node and whose parameters depend on the node for determining which branch, left or right, is to be taken in accordance with the search key. The device includes subtree register blocks for storing the recursive functions, processors for processing the recursive functions, a control unit that assigns one processor to the processing of the recursive functions contained in a block that sent the request to the control unit, and means for selecting subtrees included in the sequence of branches between the root and the leaf defined in accordance with the search key in response to the processing of blocks.
