Dynamic Data Packet Window Sizing for Wireless QoS

The patent implements dynamic adjustment of the data packet window size based on network conditions and QoS parameters. The window size is not fixed but adapts to changing bandwidth availability and round trip time, allowing the system to optimize throughput while preventing queuing overflow. This dynamic control mechanism resolves the contradiction by enabling high throughput when conditions permit while avoiding queuing inefficiencies when bandwidth is constrained.

The patent changes the parameter of window size from a static value to a dynamically adjusted parameter based on QoS bandwidth parameters and round trip time measurements. By modifying this key parameter adaptively, the system achieves high data throughput during favorable conditions while preventing network/server queuing problems during constrained conditions, thus resolving the technical contradiction between throughput and queuing efficiency.

The patent incorporates feedback mechanisms where the system continuously monitors round trip time and bandwidth parameters, then uses this feedback to adjust the window size accordingly. When round trip time increases or bandwidth decreases, the window size is reduced to prevent queuing delays. This feedback loop resolves the contradiction by automatically balancing throughput optimization against queuing delay prevention based on real-time network conditions.

The window size is implemented as a dynamic parameter that adjusts in response to changing network conditions rather than remaining fixed. The system dynamically reduces window size when queuing delays are detected and increases it when conditions improve, thereby resolving the contradiction between maximizing throughput and minimizing queuing delays through adaptive behavior.

The patent segments the bandwidth management by allocating dedicated window sizes to each data communication session based on its specific QoS bandwidth parameters. Rather than managing all sessions as a single aggregate, each session receives individualized window size allocation, which simplifies the management complexity while supporting multiple simultaneous sessions with different service requirements.

The patent implements a universal window size adjustment mechanism that can be applied across multiple different data communication sessions and service types. The same QoS-based window size calculation methodology serves all sessions regardless of their specific application, providing a unified approach that handles service versatility without proportionally increasing management complexity.
