    摘要: A method and system for transmitting packets in a packet switching network. Packets received by a packet processor may be prioritized based on the urgency to process them. Packets that are urgent to be processed may be referred to as real-time packets. Packets that are not urgent to be processed may be referred to as non-real-time packets. Real-time packets have a higher priority to be processed than non-real-time packets. A real-time packet may either be discarded or transmitted into a real-time queue based upon its value priority, the minimum and maximum rates for that value priority and the current real-time queue congestion conditions. A non-real-time packet may either be discarded or transmitted into a non-real-time queue based upon its value priority, the minimum and maximum rates for that value priority and the current real-time and non-real-time queue congestion conditions.

    摘要: A method of progressive response for invoking and suspending blocking measures that defend against network anomalies such as malicious network traffic so that false positives and false negatives are minimized. When an anomaly is detected, the detector notifies protective equipment such as a firewall or a router to invoke a blocking measure. The blocking measure is maintained for an initial duration, after which it is suspended while another test for the anomaly is made. If the anomaly is no longer evident, the method returns to the state of readiness. Otherwise, a loop is executed to re-apply the blocking measure for a specified duration, then suspend the blocking measure and test again for the anomaly. If the anomaly is detected, the blocking measure is re-applied, and its duration is adapted. If the anomaly is no longer detected, the method returns to the state of readiness.

    摘要: System and method for recording temperature on an RFID tag. A first RFID tag is attached to a container. The first RFID tag includes a temperature sensor. The container contains a multiplicity of packages. A multiplicity of second RFID tags are attached to the multiplicity of packages, respectively. The first RFID tag transmits temperature information to the multiplicity of second RFID tags. In response, the multiplicity of second RFID tags record the temperature information. Consequently, there is no need for expensive temperature sensors on the multiplicity of RFID tags on the packages. According to features of the present invention, the first RFID tag is an active RFID tag, and the multiplicity of second RFID tags are passive RFID tags. The first RFID tag also transmits other information to the multiplicity of second RFID tags to enable the second RFID tags to authenticate the temperature information. Other types of environmental sensors such as a humidity sensor or vibration sensor can substitute for the temperature sensor.

    摘要: A structure and technique for preventing collisions using a hash table in conjunction with a CAM to identify and prevent collision of binary keys. A portion of the hash value of a binary key, which does not collide with a portion of the hash value of any other reference binary key, is used as an entry in the hash table. If two or more binary keys have identical values of the portions of the hash values, each of these binary keys are stored in their entirety, in the CAM. The key in the CAM provides a pointer to a data structure where the action associated with that binary key is stored. If the binary key is not found in the CAM, the binary key is hashed, and a specific entry in the hash table is selected using a portion of this hash value.

    摘要: A remote controller is coupled to a target system via a computer network A real time probe is installed in software executing on a target system, typically a Digital Signal Processor (DSP). The remote controller includes a “debugger user interface” which accepts and interprets scoping commands issued by a developer. A controller network driver constructs appropriate network packets to be sent over the network to the target system. The target system has a control processor which runs a target network driver for receiving the network packets containing the scoping commands. The scoping commands are sent to an “embedded debugger” which performs the requested probing/scoping. When the DSP code runs across an address where the probe is installed, the embedded debugger will collect the signal values. The collected scope data will be interleaved and sent to the target network driver which, will encapsulate the information into suitable packets to send back to the controller via the network.
