Title: Optimizing the delivery of low-latency data for constantly active stations in virtual lans
Inventor: GRISWOLD VICTOR J
IPC: H04L12/56
Filed: 2005-01-18
Granted: 2010-12-07
Abstract: A method a system and a computer program for an access point to provide immediate delivery of low-latency data packets to one virtual local area network when there are one or more associated stations operating in Power-Save-Protocol on another virtual local area network. The access point observes all the virtual local area networks to which it provides access to associated stations. The access point then determines which of the virtual local area networks contains only active stations. The access point then tracks the virtual local area network having only active stations and immediately transmits to the network incoming multicast/broadcast data packets. Quality of packet data transmissions is improved, in particular, low-latency transmissions (i.e. VOIP transmissions and transmissions for stations in constantly active mode), since the packets for said transmissions are not buffered at the access point, but delivered immediately after reception, whereas packet for otheer transmissions (i.e. for station in Power save mode) are first stored and then delivered when requested by the corresponding stations. In particular, the method, computer program and system is implemented for low latency multicast/broadcast data packets being the destinations certain stations in different VLANS.

Granted: 2011-09-27
Abstract: One embodiment of the present invention provides a system for looking up location-specific configuration information for a network node or a subnet.  During system operation, a network node creates a query message containing a key that comprises an Internet Protocol (IP) prefix and a string, wherein the IP prefix identifies the network node or the subnet, and the string specifies the type of configuration information. The network node then sends the query message to a name server, which is part of a distributed system that provides a global naming service, wherein the name server additionally stores configuration information. Finally, the network node receives a response message from the name server, wherein the response message contains the requested configuration information.

Abstract: Apparatus and methods for transforming water vapor into potable water by using a vapor compression refrigeration system which includes first and second cooling elements disposed in a closed loop air passage duct that provides a continuous air circulation pattern driven by a fan or IS-002 (PCT) similar device. Water is introduced into the circulating air and undergoes adiabatic cooling followed by two stage cooling, first at a temperature below the dew point and then at a lower temperature at or below freezing. Water is collected from the air in each step and the air is thereafter heated back up by the condensing element of the refrigeration system enabling it to absorb more water vapor at the point of introduction. The air is recirculated and processed as above to permit cyclical water recovery.
