Abstract
Systems and methods applicable to a unified wired/wireless network device are proposed to address quality of service issues and roaming support for wired and wireless clients in a unified wired/wireless network. The proposed solution can include a hierarchical scheduler and shaper mechanism that is able to flexibly support different quality of service disciplines, i.e., strict-priority, guaranteed bandwidth, deficit-round-robin, etc., to allow different levels of maximum and minimum bandwidth allocation to each user or group of users. The solution can also include a dynamic queue assignment mechanism that allows queues to be moved from one queue-group and/or port to another queue-group and/or port, without losing packets, when a wireless client roams between access points within the unified network.
