Abstract: A method for providing quality of services of at least one mobile terminal in a wireless network, such as a 802.11 wireless network, wherein a service proxy functionality within an access point of the network or another entity provide quality of service operations to the at least one mobile terminal.

Abstract: A method and system for transmitting acknowledgments from an acknowledgment queue in a receiving system to a receiving system in response to receipt of a data packet from the receiving system is disclosed. An acknowledgment compressor co-located with an acknowledgment queue of the receiving system compresses a plurality of acknowledgments within the acknowledgment queue into a single acknowledgment packet. The single acknowledgment packet is transmitted from the receiving system to the sending system over a packet data network wherein it is intercepted at some point by an acknowledgment decompressor prior to receipt by the sending system. The acknowledgment decompressor regenerates the plurality of acknowledgments from the single acknowledgment packet and transmits the decompressed plurality of acknowledgments to the sending system.

Abstract: A method for monitoring and controlling the data flow in a packet data net or a datagram net comprising lines and nodes, the lines via nodes connecting by the network comprised terminals between which traffic takes place in the form of data packets or datagram. Every line and every node comprises a process preceded by a certain queue of data packets/datagram. Data packets are sent in to the net from the terminal for with a given frequency during a given time interval. If during this interval no throttling order is received from the following process, the frequency is increased by a given factor. This occurs successively until a given maximum frequency is reached. If on the other hand a throttling order is received during the interval, the frequency is instead reduced by a given factor which also occurs successively until no throttling order is received during an interval.
