Abstract: A media access controller (MAC) for wireless mesh networks comprises a quality-of-service (QoS) manager to monitor consumed bandwidth of a current application flow and to compare the consumed bandwidth with a contracted bandwidth for the current application flow. The MAC also comprises a contention manager to coordinate access to a wireless communication channel for communications with other nodes of the wireless mesh network. The QoS manager instructs the contention manager to employ signaling to request additional resources for the current application flow after the consumed bandwidth is significantly less than the contracted bandwidth.

Abstract: A system (140) aids in the tuning of one or more speech applications. The system (140) may receive event data associated with multiple user interactions with one or more speech applications and store the event data in a database (310). In a real time mode, the system (140) may receive a request for information, retrieve event data from the database (310) based on the request, formulate a response to the request using the retrieved event data, and present the response to aid in the tuning of the one or more speech applications. In a periodic mode, the system (140) may periodically analyze the event data to identify potential problem areas, generate results of the periodic analyzing, and present the results to aid in the tuning of the one or more speech applications.
