不规则多级胖树网络的优化模型
Optimization model of the irregular multi-level fat-tree network
摘要
Abstract
To reduce the cost of traditional fat-tree networks,an irregular multi-level fat-tree network (IMLFTN) is proposed,with its network node using a special basic switching module(BSM) in which the number of upward ports is fixed while the number of downward ports remains variable.Analyzing the switching mechanism and traffic distribution of each BSM,the cost function of a BSM considers its numbers of upward and downward ports,and the traffic through it as well.The BSMs used at the first level are chosen according to the total number of users,and the BSMs located at other levels are accordingly determined and connected together to form an IMLFTN.The optimal IMLFTN is selected by the total cost of all IMLFTNs constructed by the combination of BSMs with different numbers of ports.Numerical results show that the proposed IMLFTN has a large advantage in cost when constructing the network with the same number of users.关键词
