Method and apparatus for monitoring and improving performance of a queuing scheduler

Abstract

A method and apparatus is provided to monitor and improve the performance of a queuing scheduler, such as one that utilizes a WFQ calendar, by adjusting the structure of the WFQ calendar, preferably automatically. Such apparatus may be implemented using a real time calendar-monitoring (RTCM) engine. A RTCM engine preferably comprises a calendar information collector (CIC) and a sub-calendar resolution calculator (SCRC). A method may be performed, for example, by a CIC and SCRC, in several phases. For example, in the first phase, the SCRC issues a monitoring command to the CIC. In the second phase, the CIC collects the calendar information. In the third phase, the SCRC calculates the adjusted slot lengths of the sub-calendars. In the fourth phase, the CIC receives the adjusted slot lengths of the sub-calendars and applies the adjusted slot lengths on the sub-calendars.
