Method and system in a data processing system for dynamically controlling transmission of data over a network for end-to-end device flow control

摘要

A method and system provide end-to-end flow control between a sender and a receiver attached to a network. The data is divided into a plurality of packets. A priority hierarchy of a plurality of priority levels is established. Each packet of data is associated with one of the priority levels. Transmission of the plurality of packets is initiated from a transmitter to a receiver transmitting the plurality of packets in the priority hierarchy. The real-time data is divided into a plurality of frames. Each of the plurality of frame is divided into multiple packets. Each of the plurality of frames is stored in a frame buffer included within the receiver. During transmission, a level of a plurality of frames included within the frame buffer is monitored. In response to the level crossing a first buffer threshold, a determination is made as to whether a first plurality of the multiple packets are associated with a first priority level. In response, the priority level associated with the first plurality of the multiple packets is then modified to be a second priority level. Transmission is then continued where the first plurality of the multiple packets are transmitted utilizing only the second priority level.
