    Abstract: 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.

    Abstract: Some embodiments provide a system that includes several host machines for hosting several virtual machines and a physical network for interconnecting the host machines. Each host machine includes a managed physical switching element (MPSE) including several ports for performing link layer forwarding of packets to and from a set of virtual machines running on the host machine. Each port is associated with a unique media access control (MAC) address. Each host machine includes a managed routing element (MPRE) for receiving a data packet from a port of the MPSE and performing network layer routing in order to forward the received data packet from a first virtual machine of a first network segment to a second virtual machine of a second network segment.

    Abstract: Some embodiments provide a system that includes a first set of virtual machines belonging to a first overlay network and a second set of virtual machines belonging to a second overlay network. The first and second sets of virtual machines operate in several host machines, each of which includes a managed physical routing element (MPRE) for routing data packet between virtual machines in different overlay networks. A particular MPRE is configured as a bridge for routing packets between virtual machines that are in different overlay networks but in a same IP (internet protocol) subnet.
