摘要:

提出一种支持QoS的多链路最少变换动态带宽分配方法(MCDBA),该方法实现了支持不同的QoS等级,量化了带宽分配的大小,在满足一定QoS限制的条件下最小化带宽分配变换次数。仿真结果验证了MCDBA能有效地减少数据分组的时延和提高系统的带宽利用率,MCDBA可用于解决大规模网络链路接入的复杂QoS控制的实际问题。

Abstract:

A multi-link minimum change dynamic bandwidth allocation (MCDBA) algorithm that supports QoS is proposed in this research.This algorithm realizes the supports of different levels of QoS and quantifies the size of bandwidth allocation.Under the condition of meeting certain QoS limitations,the minimal bandwidth changing amount is achieved.The simulation results verify that MCDBA can effectively reduce the latency of data packet and improve the system bandwidth utilization.Thus,it is believed that MCDBA can be used in the addressing of complex QoS control under large-scale multi-link access network.

Key words: QoS level, dynamic allocation, residual bandwidth, allocation conversion
