【摘要】 DiffServ是解决宽带Internet QoS控制的一种可行方案,它在边界节点将不同的QoS要求映射成PHB.对每类具有相同PHB的IP业务流,应用VTRR公平调度算法.VTRR算法允许在竞争带宽的业务流中公平共享分配的带宽.将VTRR与RSVP结合使用,能为DiffServ提供QoS保证.更多还原

【Abstract】 ： DiffServ is a feasible solution to implement QoS＇s control in broad band Internet,it maps the requirements of different QoS into PHB in the boundary nodes.In this paper,we will use virtual－time－based round robin (VTRR) fair scheduling algorithm in each kind of IP traffic with the same PHB．VTRR permits to share allocated bands fairly among the competing flows with the same PHB.Together with resource reservation protocol,it can guarantee the QoS of flows for DiffServ．更多还原
