Abstract: In an embodiment, a computer-implemented method for dynamically exchanging runtime state data between datacenters with a gateway using a controller bridge is disclosed. In an embodiment, the method comprises: receiving one or more first runtime state data from one or more logical sharding central control planes (“CCPs”) controlling one or more logical sharding hosts; receiving one or more second runtime state data from a gateway that is controlled by a CCP that also controls one or more physical sharding hosts; aggregating to aggregated runtime state data, the one or more first runtime state data received from the one or more logical sharding CCPs and the one or more second runtime state data received from the gateway; determining updated runtime state data based on the aggregated runtime state data, the one or more first runtime state data, and the one or more second runtime state data; and transmitting the updated runtime state data to at least one of the one or more logical sharding CCPs and the gateway.

Abstract: Some embodiments provide a method for distributing a service rule that is to be enforced across a first set of sites and that is defined by reference to a group identifier that identifies a group of machines. The method distributes the service rule to each site in the first set of sites. The method identifies at least one site in the first set of sites that is not in a second set of sites that has already received a definition of the group. The method distributes the group definition to each identified site in the first set of sites that has not already received the definition of the group.

Abstract: Some embodiments provide a method for configuring a DCN migrated from a first host computer at a first site of multiple sites spanned by a logical network to a second host computer at a second site. At the second host, the method receives, from the first host, data for configuring the DCN and implementing the logical network on the second site. The data includes (i) data particular to the first site and (ii) a global identifier for a logical port to which the DCN attaches. The method provides the global identifier to a local logical network manager, which uses the global identifier to retrieve data regarding the logical port from a global network manager that manages the logical network across the sites. Based on data retrieved from the global network manager, the method modifies the data particular to the first site into data particular to the second site.

Abstract: Available buffers in the memory space of a guest operating system of a virtual machine are provided to a network interface controller (NIC) for use during direct memory access (DMA) and the guest operating system is notified accordingly when data is written into such available buffers. These capabilities obviate the requirement of using hypervisor memory as a staging area to determine which virtual machine to forward incoming data.

Abstract translation: 在虚拟机的客户操作系统的存储器空间中的可用缓冲器被提供给网络接口控制器（NIC）以在直接存储器访问（DMA）期间使用，并且当数据被写入这样的可用缓冲器时相应地通知客户机操作系统 。 这些功能避免了使用管理程序内存作为分段区域来确定哪个虚拟机转发输入数据的要求。

Abstract: Example methods and systems for a network management entity to perform topology-aware control information dissemination in a software-defined networking (SDN) environment. The method may comprise obtaining group topology information specifying a network group, and a network configuration object that references the network group. The method may also comprise: processing the group topology information to identify, from multiple members of the network group, a first member that is relevant to a first host; and processing the group topology information to identify, from the multiple members, a second member that is irrelevant to the first host. The method may further comprise: generating and sending, to the first host, control information associated with a subset of the network group. The subset may include the first member but exclude the second member.

Abstract: Some embodiments provide a network management system for managing a logical network that spans multiple physical sites. The network management system includes a global network manager for receiving global logical network configuration data for the multiple physical sites. The network management system includes, at each of the physical sites, (i) a local network manager for receiving a logical network configuration for the physical site from the global network manager and (ii) a set of central controllers for distributing logical network configuration data to computing devices that implement the logical network at the physical site.

Abstract: Systems and methods of communicating between a plurality of hosts comprising one or more first hosts controlled by a first control plane and one or more second hosts controlled by a second control plane are disclosed herein. Each of the one or more first hosts runs at least one tunneling endpoint of one or more first tunneling endpoints, and each of the one or more second hosts runs at least one tunneling endpoint of one or more second tunneling endpoint. The method includes storing, at each of the one or more first hosts, a global list identifying at least the one or more second tunneling endpoints. The method further includes receiving a packet at one of the one or more first tunneling endpoints. The method further includes replicating, encapsulating, and transmitting the packet to each of the one or more second tunneling endpoints based on the global list.
