Techniques for managing priority queues and escalation considerations in USB wireless communication systems

摘要

Quality of Service (QoS) mechanisms and facilities are introduced into USB-based wireless Local Area Networking (LAN) communication systems. Techniques are provided for managing multiple priority queues in USB-based wireless communications systems, and for ensuring that lower priority traffic is not precluded from accessing the medium during sustained periods of use by high(er) priority traffic. A method is provided to resolve Quality of Service issues in emerging high-speed USB-based communications systems by offering support for multiple queue management within the system. A further embodiment provides an escalation mechanism for the purposes of mitigating low priority class data starvation in these communications systems, when it becomes an issue. QoS initiatives escalate a lower priority traffic class for the purposes of mitigating low priority class data starvation of the present invention, and/or use a single data buffer with management techniques to temporarily block or flow control data on a lower priority channel.
