| 摘 要： | 提出了一种核心无状态的自适应比例公平带宽分配机制CSPAFA（core stateless proporitonal adaptive fair allocation)，在边界路由器完成基于每个流的状态处理，将所有流分成标记流和非标记流两种业务类型，采用DPS（dynamic packet state)技术将有关信息编码进IP分组头，在核心将输出链路带宽分成两部分，核心根据当前的网络负荷对标记流按服务规格成比例的分配输出链路带宽，对未标记流公平分配带宽，并且能自适应地调整两类业务的带宽共享比例，最后，给出了在NS网络仿真环境下的仿真实验结果。 |

A CORE-STATELESS PROPORTIONAL ADAPTIVE FAIR BANDWIDTH ALLOCATION MECHANISM |
|
| Abstract: | A core stateless proportional adaptive fair bandwidth allocation mechanism (CSPAFA) is presented, which performs per flow state management in edge router. In CSPAFA, the edge routers differentiate between marked flows and non marked flows. By using DPS, the relevant information is inserted into IP header in edge routers. Core routers allocate proportionally output link bandwidth to marked flows according to their service profiles and current network load, and perform fair bandwidth allocation for non marked flows. In addition, CSPAFA can adjust dynamically bandwidth allocation between marked flows and non marked flows. Finally, the simulation results are given and CSPAFA is testified. |
