Cloud computing has changed the ITC industry. Companies like Amazon, Google and Microsoft have built large computing clusters of as many as 1 million servers. Each server can run multiple virtual machines and these virtual machines are rented to cust…

网络资源同计算资源以及存储资源一样,是一种可被租户共享使用并提高利用率的资源.但是,不同租户的计算资源以及存储资源之间,有很强的隔离性,可以实现按需按比例分配的使用方式,但是网络资源却不可以. 主要原因是,一台虚拟机使用的网络资源,会受到在同一台物理服务器其他虚拟机的影响(竞争唯一的网卡资源),以及其他会同此虚拟机进行通信的虚拟机影响(竞争此虚拟机的可用带宽),此外其他虚拟机之间的通信也会竞争此虚拟机通信时可使用的链路资源. 因此需要在公平分配以及最小带宽保障之间需要进行取舍(其实还是以公平分配…
