摘要： The invention relates to a system and method of dispersion measurement in an optical fiber network. The invention provides means for transmitting from a transmitting node, using a single tunable laser transmitter, two consecutive bursts of data at different wavelengths λ1 and λ2 to a receiver node, wherein each burst of data comprises a unique sequence of amplitude modulated data, and wherein the two sequences are injected with a fixed known delay. The delay between the two consecutive bursts of data is maintained by selective switching of the tunable laser, such that clock recovery circuitry at the receiver node remains locked during the delay between the two bursts. The dispersion measurements method of the present invention is based on walk off and bit position detection between two wavelengths suitable for fast optical burst switching network is described. This method does not require an operator, extra equipment, or traffic interruption on the network.

摘要： Chemical vapor deposition processes utilize higher order silanes and germanium precursors as chemical precursors. The processes have high deposition rates yet produce more uniform films, both compositionally and in thickness, than films prepared using conventional chemical precursors. In preferred embodiments, trisilane is employed to deposit SiGe-containing films that are useful in the semiconductor industry in various applications such as transistor gate electrodes.

摘要： Sequential processes are conducted in a batch reaction chamber to form ultra high quality silicon-containing compound layers, e.g., silicon nitride layers, at low temperatures. Under reaction rate limited conditions, a silicon layer is deposited on a substrate using trisilane as the silicon precursor. Trisilane flow is interrupted. A silicon nitride layer is then formed by nitriding the silicon layer with nitrogen radicals, such as by pulsing the plasma power (remote or in situ) on after a trisilane step. The nitrogen radical supply is stopped. Optionally non-activated ammonia is also supplied, continuously or intermittently. If desired, the process is repeated for greater thickness, purging the reactor after each trisilane and silicon compounding step to avoid gas phase reactions, with each cycle producing about 5-7 angstroms of silicon nitride.

摘要： A method of securing a network from vulnerability exploits, including the steps of a traffic analysis engine receiving a plurality of packets destined for an internal operating system; the traffic analysis engine selectively forwarding the packets to at least one virtual machine emulating the internal operating system; the virtual machine processing each forwarded packet; a rapid analysis engine identifying a malicious packet from the processed packets; and the rapid analysis engine creating a new signature to identify the malicious packet.

摘要： A method for detection of a network address translation (NAT) device in a network is described herein. An edge network device detects a first packet at an edge port of the edge network device. A second packet is detected at the edge port of the edge network device. It is determined whether a time to live (TTL) value associated with the first packet is different from a TTL value associated with the second packet. Where the TTL value associated with the first packet is different from a TTL value associated with the second packet, it is determined that a NAT device is connected to the edge port. Where the TTL value associated with the first packet is the same as a TTL value associated with the second packet, it is determined that a NAT device is not connected to the edge port.
