Method and device for joint dynamic sliding window management of multiple ARQ data links

摘要

There is disclosed a method and a device of Method of dynamic ARQ windows management in a network for controlling data link transmission. The method comprises an ARQ management entity selecting a given operational control mode, and a transmitter sending one or more PDUs of a given data link to a receiver. The receiver stores received PDUs in a shared memory. A receiver ARQ instance sends back corresponding ARQ-ACK message including a specific information comprising selected operational control mode and/or a flow control data. It further removes acknowledged PDUs from the shared memory when delivering them to an upper layer. The transmitter ARQ instance continues or stops PDUs transmission upon reception of the ARQ-ACK message, based on the specific information comprised therein. The step of selecting the operational control mode is repeated dynamically on a per data link basis during PDUs transmission, while taking into account the available memory space within the shared memory, said respective associated QoS priority, as well as the sliding window memory requests received from the transmitters by the receiver. <IMAGE>
