    • Computerized methods, systems, and computer-readable media are provided for establishing and managing a virtual network (V-net) and virtual machine (VM) switches that enable protected and isolated interconnections between members of the V-net. The V-net members include an originating network adapter that generates data packets addressed to a destination network adapter. Upon detecting data-packet generation, a source-side VM switch accesses a forwarding table associated with the V-net, ascertains a destination-side, VM-switch locator that corresponds to an identifier of the destination network adapter, and modifies the data packets to include the identifier. The forwarding table represents a mapping between the members of the V-net and VM switches located on respective nodes within the data center. In operation, the mapping enforces communication policies that govern data-packet traffic. Upon receiving the data packets, the destination-side VM switch restores the data packets and forwards them to the destination network adapter.
    • 提供了计算机化方法,系统和计算机可读介质,用于建立和管理虚拟网络(V-net)和虚拟机(VM)交换机,从而实现V-net成员之间的保护和隔离互连。 V-net成员包括生成发往目标网络适配器的数据包的始发网络适配器。 在检测到数据包生成时,源侧VM交换机访问与V-net相关联的转发表,确定与目的网络适配器的标识符相对应的目的地侧的VM交换机定位符,并修改数据包 包括标识符。 转发表表示位于数据中心内的相应节点上的V-net和VM交换机的成员之间的映射。 在操作中,映射强制执行数据包流量的通信策略。 目的端VM交换机接收到数据包后,恢复数据包并将其转发到目的网络适配器。
