摘要： Some embodiments of the invention provide a method for gathering data for logical network traffic analysis by sampling flows of packets forwarded through a logical network. Some embodiments are implemented by a set of network virtualization controllers that, on a shared physical infrastructure, can implement two or more sets of logical forwarding elements that define two or more logical networks. In some embodiments, the method (1) defines an identifier for a logical network probe, (2) associates this identifier with one or more logical observation points in the logical network, and (3) distributes logical probe configuration data, including sample-action flow entry data, to one or more managed forwarding elements that implement the logical processing pipeline at the logical observation points associated with the logical network probe identifier. In some embodiments, the sample-action flow entry data specify the packet flows that the forwarding elements should sample and the percentage of packets within these flows that the forwarding elements should sample.
摘要翻译：本发明的一些实施例提供了一种用于通过对通过逻辑网络转发的分组的流的采样来收集用于逻辑网络流量分析的数据的方法。一些实施例由一组网络虚拟化控制器实现，所述网络虚拟化控制器在共享物理基础设施上可以实现定义两个或多个逻辑网络的两组或更多组逻辑转发元件。在一些实施例中，方法（1）定义逻辑网络探测器的标识符，（2）将该标识符与逻辑网络中的一个或多个逻辑观察点相关联，以及（3）分发逻辑探测器配置数据，包括采样动作流入口数据提供给在与逻辑网络探测标识符相关联的逻辑观测点处实现逻辑处理流水线的一个或多个管理转发元件。在一些实施例中，采样动作流入口数据指定转发元素应该采样的分组流和转发元素应该采样的这些流内的分组的百分比。

摘要： Some embodiments provide a network system. The network system includes a first set of host machines for hosting virtual machines that connect to each other through a logical network. The first set of host machines includes managed forwarding elements for forwarding data between the host machines. The network system includes a second set of host machines for hosting virtualized containers that operate as gateways for forwarding data between the virtual machines and an external network. At least one of the virtualized containers peers with at least one physical router in the external network in order to advertise addresses of the virtual machines to the physical router.
摘要翻译：一些实施例提供网络系统。网络系统包括用于托管通过逻辑网络彼此连接的虚拟机的第一组主机。第一组主机包括用于在主机之间转发数据的托管转发元件。网络系统包括用于托管虚拟化容器的第二组主机，其作为用于在虚拟机和外部网络之间转发数据的网关。至少一个虚拟化容器与外部网络中的至少一个物理路由器对等，以便将虚拟机的地址通告给物理路由器。
