摘要： Some embodiments provide a system that implements a set of tools to define a set of one or more logical forwarding elements from a number of physical forwarding elements and a scalable framework to retrieve statistics relating each logical forwarding element. In some embodiments, the statistics relate to the logical ports of a logical forwarding element. The system of some embodiments allows a network administrator to retrieve a total packet count and byte count for one or more logical ports of the logical forwarding element, even though the logical ports may be distributed across multiple physical forwarding elements.

摘要： Some embodiments provide a statistics collection framework that is used to aggregate statistic for interfaces such as logical ports and logical port pairs. Flows that are related with these interfaces are tagged with the identifier of the logical entities for which statistics are being collected. The interface statistics is periodically sent in the background to a statistics aggregator. The read queries for the interface statistics are directed to the statistics aggregator. The statistics aggregator, therefore, acts as a cumulative cache for the interface statistics.

摘要： Some embodiments provide a local network controller that manages a first managed forwarding element (MFE) operating to forward traffic on a host machine for several logical networks and configures the first MFE to forward traffic for a set of containers operating within a container virtual machine (VM) that connects to the first MFE. The local network controller receives, from a centralized network controller, logical network configuration information for a logical network to which the set of containers logically connect. The local network controller receives, from the container VM, a mapping of a tag value used by a second MFE operating on the container VM to a logical forwarding element of the logical network to which the set of containers connect. The local network controller configures the first MFE to apply the logical network configuration information to data messages received from the container VM that are tagged with the tag value.

摘要： Some embodiments provide a method for a first managed forwarding element (MFE). The method receives a data message that includes a logical context tag that identifies a logical port of a particular logical forwarding element. Based on the logical context tag, the method adds a local tag to the data message. The local tag is associated with the particular logical forwarding element, which is one of several logical forwarding elements to which one or more containers operating on a container virtual machine (VM) belong. The container VM connects to the first MFE. The method delivers the data message to the container VM without any logical context. A second MFE operating on the container VM uses the local tag to forward the data message to a correct container of several containers operating on the container VM.
