【摘要】：为了降低传统胖树网络的成本,提出不规则多级胖树网络,其节点使用具有固定数目上行端口和不同数目下行端口的特殊基本交换模块.分析该网络中各交换模块交换机制及其流量分布,交换模块成本函数综合考虑其上下行端口数及其通过流量;根据总用户数选择网络第1级交换模块,再依次确定其余层交换模块,相互连接交换模块形成不规则多级胖树网络,在不同端口交换模块组合构建的所有网络中选择总成本最优的不规则多级胖树网络.数值计算结果表明,构建相同用户数的交换网络,使用所提不规则多级胖树网络具有较大的成本优势.
[Abstract]:In order to reduce the cost of traditional fat-tree networks, an irregular multilevel fat-tree network is proposed, in which the nodes use special basic switching modules with fixed number of uplink ports and different numbers of downlink ports. The switching mechanism of each switching module and its traffic distribution in the network are analyzed. The cost function of the switching module considers the number of upstream and downstream ports and its traffic, and selects the first switching module of the network according to the total number of users. The other layer switching modules are determined in turn, and the irregular multilevel fat tree network is formed by connecting the switch modules with each other, and the irregular multilevel fat tree network with the best total cost is selected among all the networks constructed by the combination of different port switching modules. Numerical results show that using the proposed irregular multilevel fat tree network to construct a switching network with the same number of users has a large cost advantage.
