摘要： The advantage of a logical network implemented with hypervisors is well understood. However, it is still often necessary to provide bridging between a logical network (such as VXLAN) and a physical network (such as VLAN). This is particularly so when customers of network virtualization need L2 centric protocols on hybrid networks where logical networks and physical networks co-exist. Bridging also allows seamlessly transition between L2 centric workloads into VMs on hypervisors.
摘要翻译：利用虚拟机管理程序实现的逻辑网络的优点是很好理解的。然而，通常需要在逻辑网络（如VXLAN）和物理网络（如VLAN）之间提供桥接。当网络虚拟化的客户在逻辑网络和物理网络共存的混合网络中需要L2中心协议时，情况尤其如此。桥接还可以将L2中心工作负载之间的无缝转换转换为虚拟机管理程序中的虚拟机。

摘要： 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.

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.
