    摘要: Systems and methods consistent with this invention allow for each node within one or more rings to obtain connection and topology information from other nodes within these rings. In such a system, each node is able to maintain connection table and topology tables for each node and each ring within a ring network. In particular, such information can be kept current because this scheme allows for dynamic updating of connection and topology information in real time. With such current information, a node is able to utilize this information to execute such operations as squelching connections on a protect line and timeslot interchange. In addition, by supporting timeslot interchange, the ring can be managed as more than a single logical entity as well as can have better bandwidth management utilization.

    摘要: A method, system and egress switching node for maintaining a network connection in an optical network reduces the number of spans needed for reestablishing a network connection. The invention learns which channels are used by the network connection and propagates such channel assignment data to the switching nodes for storage therein. When a span failure occurs, a notification is sent to the switching nodes identifying which span has failed. The switch nodes use the notification and channel assignment data to perform protection switching such that the rerouted network connection selects the channel that was used by the network connection on the failed span. Likewise, the egress switching node uses the selected channel to drop the network connection from the protecting fibers. This enables a network connection to travel a shorter distance after a protection switch.

    摘要: Mechanisms for wireless local area network coverage enhancement using dynamic antennas are provided. The dynamic antennas may be used, for example, in an antenna apparatus of an access point. The access point maps a plurality of virtual access points (VAPs), each VAP corresponding to at least one of a plurality of directional antenna patterns of the antenna apparatus. The processor transmits broadcast communication on each of the VAPs a further distance from the access point as compared to transmitting on an omnidirectional antenna pattern of the antenna apparatus.

    摘要: An ammonium phosphate containing fire retardant is combined with a fluoropolymer and/or a penetrating barrier, borate-containing formulation having resistance to water damage with protective properties coming from materials such as used in food packaging and cosmetics and/or a medium-to-long chain polar carboxyl substance, and/or a medium-to-long chain polar carboxyl substance without borate, so as to make a composition. The composition can be aqueous. It can be a liquid of light to moderate viscosity, or may be a concentrated or dried version, which may contain a neutral ammonium phosphate and perhaps other ingredient(s) such as a mold inhibitor, an insecticide, a stain protector, and so forth and the like. The mold inhibitor can have especial activity against toxic black mold (Stachybotrys chartarum). The insecticide may be a termiticide. Such a composition can be made by contacting the fire retardant and other necessary ingredient(s) under conditions sufficient to form the composition; it can be used by contacting it with a substrate, which beneficially is otherwise flammable. A process for incorporation of an ammonium phosphate containing fire retardant into wood includes contacting the wood with a liquid at an effective pH above the pH of the wood, where the liquid embraces a combination in proximity or time of an amine oxide and a buffering agent, as well as the ammonium phosphate containing fire retardant, under conditions such that the ammonium phosphate containing fire retardant is incorporated into the wood. Another aspect is the composition or its residue in combination with the substrate.

    摘要: A horizontally polarized antenna array allows for the efficient distribution of RF energy into a communications environment through selectable antenna elements and redirectors that create a particular radiation pattern such as a substantially omnidirectional radiation pattern. In conjunction with a vertically polarized array, a particular high-gain wireless environment may be created such that one environment does not interfere with other nearby wireless environments and avoids interference created by those other environments. Lower gain patterns may also be created by using particular configurations of a horizontal and/or vertical antenna array. In a preferred embodiment, the antenna systems disclosed herein are utilized in a multiple-input, multiple-output (MIMO) wireless environment.

    摘要: A method for unicast packet conversion whereby a unicast packet is received at a receiving node followed by a determination as to whether the destination address is identified in the packet. If the address is identified, then the unicast packets are converted to a multicast packet and forwarded to a connected station. If a destination network address is not identified, then the packet is forwarded to the connected station.

    摘要: A wireless device having vertically and horizontally polarized antenna arrays can operate at multiple frequencies concurrently. A horizontally polarized antenna array allows for the efficient distribution of RF energy in dual bands using, for example, selectable antenna elements, reflectors and/or directors that create and influence a particular radiation pattern. A vertically polarized array can provide a high-gain dual band wireless environment using reflectors and directors as well. The polarized horizontal antenna arrays and polarized vertical antenna arrays can operate concurrently to provide dual band operation simultaneously.
