Abstract
A method and system is provided for link layer scheduling for networked applications in a coordinator-based communications system. A network-coordinating device receives a request from a networked application to establish a communications session. The request includes a set of session parameters. The network-coordinating device allocates a first transmission opportunity in response to the request. The network-coordinating device allocates successive transmission opportunities based on the set of session parameters without receiving successive requests. The set of session parameters comprises at least one of a predetermined flow control mechanism, a quality-of-service (QoS) requirement, a bandwidth requirement, and an application type. In one embodiment, the predetermined flow control mechanism is additive increase and multiplicative decrease (AIMD) of transmission control protocol (TCP). Using the novel link layer scheduling, the network-coordinating device is able to allocate and adjust successive transmission opportunities to match the upper-layer resource requirement and traffic pattern dynamically.
