资源预留动态带宽分配机制

提出一种基于资源预留的核心无状态动态带宽分配机制,采取了一种无状态递归观察机制动态调整预留带宽值的做法,使得可靠性和强壮性大大增强。文中采取3种技术来实现预留带宽的动态分配：一种是在控制面的轻质认证;第二种是在数据面采用一种无状态递归观察技术;第三种是业务区分机制,将业务流分为标记流和非标记流。给出了在ns网络仿真环境下的仿真实验结果。

Dynamic Bandwidth Allocation Mechanism Based on Resource Reservation

This paper presented a core-stateless dynamic bandwidth allocation mechanism based on resource reservation, A stateless recursive monitoring mechanism was introduced to adjust the reservation bandwidth dynamically, which enhanced the scalability and robustness of QOS. To achieve bandwidth allocation dynamically, three key techniques were developed. The first one was the lightweight certificates on control planes, the second one was stateless recursive monitoring mechanism on data planes and the last one was that the traffics were divided into marked flows and non-marked flows. Finally, the simulation results were presented and the mechanism was testified.
