摘要
BBQ, Budget-Based QoS management infrastructure, is designed to offer end-to-end QoS assurance for All-IP networks. BBQ takes pre-planning approach to forecast incoming traffic based on historic statistics and allocates link resources accordingly. We designed an overbooking mechanism to compensate forecasting errors and to reduce performance degradation accordingly. We also propose an over-admission method to compensate resource under-utilization when some traffics such as telephony are not persistently active during its life time. Simulations show both methods can enhance resource utilization effectively.
