Abstract:

RIO is the active queue management （AQM） algorithm for DiffServ AF PHB, which is based on RED. As the performance of RED is sensitive to configurati on parameters, the performance of RIO is also sensitive to configuration parameters. PI is the AQM algorithm based on control theory and has smaller que ue length oscillation than RED. PIP improves the convergence speed of PL The paper designs a new AQM for DiffServ AF PHB based on PIP, which is called P  IPIO. PIPIO has smaller queue length oscillation than RIO and can protect high-priority packets.

Key words:  （differentiated services, assured forwarding, active queue management）
