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.

摘要： Some embodiments provide a method for a managed forwarding element (MFE). The method receives a packet from a data compute node for which the MFE performs first-hop processing. The data compute node is associated with multiple tunnel endpoints of the MFE. The method determines a destination tunnel endpoint for the packet. The method uses a load balancing algorithm to select one of the multiple tunnel endpoints of the MFE as a source tunnel endpoint for the packet. The method encapsulates the packet in a tunnel using the source and destination tunnel endpoints.

摘要： A novel method of conducting multicast traffic in a network is provided. The network includes multiple endpoints that receive messages from the network and generate messages for the network. The endpoints are located in different segments of the network, each segment including one or more of the endpoints. For a source endpoint to replicate a particular message (e.g., a data packet) for all endpoints belonging to a particular replication group (i.e., multicast group) within the network, the source endpoint replicates the particular message to each endpoint within the source endpoint's own segment and to a proxy endpoint in each of the other segments. Each proxy endpoint in turn replicates the particular message to all endpoints belonging to the particular replication group within the proxy endpoint's own segment.
