    摘要： Some embodiments provide a method for a first network controller that manages a logical network implemented in a datacenter including forwarding elements to which the first network controller does not have access. The method identifies a first data compute node (DCN) in the datacenter configured to execute a second network controller. The method distributes configuration data defining the logical network to the first DCN. The second network controller distributes sets of the configuration data to local agents executing on additional DCNs in the datacenter that send and receive messages through the logical network. Both managed forwarding elements and the local agents execute on each of the additional DCNs. Each local agent on a particular DCN is for receiving a set of configuration data from the second network controller and configuring the managed forwarding element on the particular DCN to implement the logical network according to the set of configuration data.

    摘要： A method for a network controller that manages a logical network spanning multiple physical locations. For each physical location hosting data compute nodes (DCNs) belonging to the logical network, the method defines a centralized routing component for processing data messages between the DCNs hosted at the physical location and networks external to the logical network, assigns an active instance of the centralized routing component to operate at the physical location, and assigns a standby instance of the centralized routing component to operate at one of the other physical locations.

    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.
