PFQ

To achieve linear relation between service rates and reserved rates of guaranteed services, the P~ 2PFQ scheduling algorithm was presented. Depending on an approximation factor, the phenomenon that the PFQ is ahead of GPS is eliminated.

为控制资源预留业务的实际服务速率，提出了带逼近因子的P2PFQ调度算法，一方面缓解了PFQ系统的数据超前发送现象；
