【摘要】：為了降低傳統(tǒng)胖樹(shù)網(wǎng)絡(luò)的成本,提出不規(guī)則多級(jí)胖樹(shù)網(wǎng)絡(luò),其節(jié)點(diǎn)使用具有固定數(shù)目上行端口和不同數(shù)目下行端口的特殊基本交換模塊.分析該網(wǎng)絡(luò)中各交換模塊交換機(jī)制及其流量分布,交換模塊成本函數(shù)綜合考慮其上下行端口數(shù)及其通過(guò)流量;根據(jù)總用戶(hù)數(shù)選擇網(wǎng)絡(luò)第1級(jí)交換模塊,再依次確定其余層交換模塊,相互連接交換模塊形成不規(guī)則多級(jí)胖樹(shù)網(wǎng)絡(luò),在不同端口交換模塊組合構(gòu)建的所有網(wǎng)絡(luò)中選擇總成本最優(yōu)的不規(guī)則多級(jí)胖樹(shù)網(wǎng)絡(luò).數(shù)值計(jì)算結(jié)果表明,構(gòu)建相同用戶(hù)數(shù)的交換網(wǎng)絡(luò),使用所提不規(guī)則多級(jí)胖樹(shù)網(wǎng)絡(luò)具有較大的成本優(yōu)勢(shì).
[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.
