一种EPON-WiMAX融合网络带宽分配算法

文中提出了一种应用于EPON和WiMAX的融合网络,实现用户多优先级业务区分并保证用户QoS的动态带宽分配算法。算法让EPON网络和WiMAX网络协同分配带宽,在EPON网络带宽分配的过程中加入WiMAX网络的带宽分配。整体算法使得因得不到足够带宽而受到影响的用户数保持在最小,同时加入令牌机制兼顾了用户之间的公平性。文中在现有融合网络框架的基础上提出算法,并给出了算法的具体设计步骤,详细分析了带宽申请和分配的过程,讨论了算法的优越性。

A Bandwidth Allocation Algorithm for Convergence Network of EPON WiMAX

A dynamic bandwidth allocation algorithm which could achieve multiple-traffic-distinction and guarantee QoS for the integrated network of EPON and WiMAX is described.For EPON and WiMAX work in a collaborative way for bandwidth allocation in the integrated network,this algorithm makes the subscribers who could not get enough bandwidth the smallest in quantity,and meanwhile,gives consideration to the fairness among between the subscribers.Thus the special allocation algorithm is proposed,the specific design given,the process of bandwidth application and allocation analyzed,and the advantage of this algorithm discussed in this paper.
