    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 result in films having low dielectric constants when suitable chemical precursors are utilized. Preferred chemical precursors include siloxanes, (fluoroalkyl)fluorosiloxanes, (fluoroalkyl)silanes, (alkyl)fluorosilanes, (fluoroalkyl)fluorosilanes, alkylsiloxysilanes, alkoxysilanes, alkylalkoxysilanes, silylmethanes, alkoxysilylmethanes, alkylalkoxysilylmethanes, alkoxymethanes, alkylalkoxymethanes, and mixtures thereof. The precursors are particularly suited to thermal CVD for producing low dielectric constant films at relatively low temperatures, particularly without the use of additional oxidizing agents. Such films are useful in the microelectronics industry.

    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.
