【摘要】:軟件定義網(wǎng)絡(luò)(SDN)是一種新型的網(wǎng)絡(luò)架構(gòu),其路徑是根據(jù)全局網(wǎng)絡(luò)拓?fù)溆?jì)算得到的。然而,當(dāng)前SDN網(wǎng)絡(luò)中依然存在負(fù)載不均衡和不能滿足網(wǎng)絡(luò)流量QoS要求的問題。為此,根據(jù)SDN控制器掌握全局網(wǎng)絡(luò)信息的特點(diǎn),結(jié)合網(wǎng)絡(luò)感知功能和基于流量的業(yè)務(wù)劃分,利用K最短路徑算法,提出一種基于業(yè)務(wù)劃分的路由選擇機(jī)制。實(shí)驗(yàn)結(jié)果表明,該機(jī)制能夠?yàn)椴煌瑯I(yè)務(wù)類型的數(shù)據(jù)流選擇一條最能滿足其QoS要求的路徑,并使整個網(wǎng)絡(luò)達(dá)到負(fù)載均衡,進(jìn)而提高了底層網(wǎng)絡(luò)資源的利用率。
[Abstract]:The software defined network (SDN) is a new network architecture whose path is calculated according to the global network topology. However, the current SDN network still exists the problem of load imbalance and can not meet the network traffic QoS requirements. Therefore, according to the characteristics of global network information grasped by SDN controller, combined with network perception function and traffic partition, a route selection mechanism based on traffic partition is proposed by using K shortest path algorithm. The experimental results show that the mechanism can select a path that can best meet the QoS requirements for different traffic types of data streams, and make the whole network achieve load balance, thus improving the utilization of the underlying network resources.
