A method for optimizing the throughput of TCP / IP applications by aggregating user application data and consolidating multiple TCP / IP connection streams into a single optimized stream for delivery to a destination application. Optimization of the internet protocol uses a packet interceptor to intercept packets from a source application, a packet driver to aggregate the intercepted packets, a data mover to transport the aggregated packets to another data mover at the destination, a destination packet driver to disaggregate the transported aggregated packets, and a destination end processor to deliver the disaggregated IP packets to the destination application.

A method and apparatus for aggregating packets in a wireless communication system. The data to be transmitted is selected and packetized and formed into frames for transmission. Rather than send each frame individually, frames are grouped and transmitted with grouping indicia informing the recipients how to acknowledge successful receipt of the transmitted data. ACKs are sent at a predetermined time, or all together, divided by subcarrier in the case of an OFDMA network.

A wireless communication system including transmitters for determining a transmission rate for an associated receiver according to channel state information fed back from associated receivers, and transmitting packets at the determined transmission rate. In a communication method, a transmitter groups packets to be transmitted to the receivers according to transmission rates, and generates frames configured by packets with an identical transmission rate. The transmitter aggregates frames with different transmission rates into one transmission burst, and sends the transmission burst. The data communication method based on packet aggregation can efficiently manage resources by determining transmission rates for reception stations (STAs) on the basis of feedback channel state information in a transmission STA, aggregating packets to be transmitted to the reception STAs to form a packet group, and transmitting packet groups with different transmission rates using one multi-rate aggregation (MRA) burst.

A method and equipment is used to transmit and / or receive time delay-intolerant information over a communication system. The information is transmitted in aggregated form. A plurality of packets representing time delay-intolerant information is combined to form an aggregate packet. The aggregate packet is formed based on user service requirements while maintaining time delay requirements of the information. The size of the aggregated is formed from a negotiation between the transmitting equipment and receiving equipment. Because of the use of an aggregated packet less scheduling of packets is done and the aggregated packet can be transmitted at a rate different than the fixed rate of the time delay-intolerant information. The equipment comprises transmit equipment and receive equipment. The transmit equipment contains an aggregator that combines a plurality of packets based on user service requirements. The packets to be transmitted are retrieved at the fixed rate of the time delay-intolerant information. The size of the aggregate packet can be determined on a static or dynamic basis. The receiving equipment contains a de-aggregator circuit that receives aggregated packets and generates individual packets from the received aggregated packet. The generated individual packets are retrieved from the de-aggregator at the fixed rate of the time delay-intolerant information.

Methods and apparatus for improving the efficient use of a wireless channel. Flows of compatible packets to be transmitted are processed in separate queues based on characteristics of the packets, destination and quality of service (QoS) requirements. Aggregation parameters selected for each flow define when packets aggregated on a flow are to be sent. The aggregation parameters may reflect packet type, such as QoS requirements, an application type and / or wireless channel conditions. In some embodiments, the aggregation parameters indicate a threshold frame size or include a threshold time to buffer a packet while waiting for other packets on that flow to fill a frame. When an aggregation parameter for a queue is met, the aggregated packets are transmitted as a frame. The queue is cleared and subsequent packets may begin aggregating. Some types of packets, such as acknowledgment packets, may be sent without aggregation.

A transmission window size threshold represents a boundary for a size of a transmission window when transmission of existing frames may be delayed. The frames are bundled according to the bundling factor if the transmission window size is greater than the transmission window size threshold.
