    摘要： A system for network virtualization in which physical network resources in different physical contexts are configured to implement one or more distributed logical network elements, at least some of the physical network resources implementing the distributed logical network elements configured according the physical context of those network resources. The local configuration of a physical locale is a version of the logical configuration that is modified specifically for the physical locale. Such modification is based on locale identifiers that are assigned to the physical locales. Some systems use locale-specific information to modify next- hop preference. Some system use locally modified configurations to determine the placement of VMs.

    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 logical routing element (LRE) having multiple designated instances for routing packets from physical hosts (PH) to a logical network is provided. A PH in a network segment with multiple designated instances can choose among the multiple designated instances for sending network traffic to other network nodes in the logical network according to a load balancing algorithm. Each logical interface (LIF) of an LRE is defined to be addressable by multiple identifiers or addresses, and each LIF identifier or address is assigned to a different designated instance.
