摘要： Some embodiments provide a method for a public cloud manager operating within a first data compute node of a public cloud. The method receives, through a set of public cloud provider APIs, information regarding a new second data compute node created within the public cloud. The information includes a set of tags entered by a user when creating the data compute node. Based on the tags, the method notifies a network control system that manages a forwarding element operating in the data compute node regarding (i) the creation of the data compute node, (ii) a logical switch to which to attach the data compute node and (iii) a security group to which the data compute node belongs.

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： Virtualization software that includes a VDRB (virtual distributed router/bridge) module for performing L3 routing and/or bridging operations is provided. At least some of the VDRBs are configured as VDBs (virtual distributed bridge) for performing bridging operations between different network segments in a distributed manner. The bridging tasks of a network are partitioned among several VDBs of the network based on MAC addresses. MAC addresses of VMs or other types of network nodes belonging to an overlay logical network are partitioned into several shards, each shard of MAC addresses assigned to a VDB in the network. Each VDB assigned a shard of MAC addresses performs bridging when it receives a packet bearing a MAC address belonging to its assigned shard. A VDB does not perform bridging on packets that do not have MAC address that falls within the VDB's shard of MAC addresses.

摘要： Some embodiments provide a method for identifying a realization status of one or more logical entities of a logical network. In some embodiments the method is implemented by a controller that controls network data communications in a logical network. The method receives a request for realization status of a set of logical entities at a particular point of time that is associated with a particular value of a realization number. The method determines whether configuration data up to the particular point of time for each logical entity in the set has been processed and distributed to a set of local controllers that operates on a set of host machines. The method returns a realization reply that includes a successful realization message when the configuration data up to the particular point in time for each logical entity in the set has been processed and distributed to the set of local controllers.

摘要： A LRE (logical routing element) that have LIFs that are active in all host machines spanned by the LRE as well as LIFs that are active in only a subset of those spanned host machines is provided. A host machine having an active LIF for a particular L2 segment would perform the L3 routing operations for network traffic related to that L2 segment. A host machine having an inactive LIF for the particular L2 segment would not perform L3 routing operations for the network traffic of the L2 segment.

摘要： Multiple TCP/IP stack processors on a host. The multiple TCP/IP stack processors are provided independently of TCP/IP stack processors implemented by virtual machines on the host. The TCP/IP stack processors provide multiple different default gateway addresses for use with multiple processes. The default gateway addresses allow a service to communicate across an L3 network. Processes outside of virtual machines that utilize the TCP/IP stack processor on a first host can benefit from using their own gateway, and communicate with their peer process on a second host, regardless of whether the second host is located within the same subnet or a different subnet. The multiple TCP/IP stack processors can use separately allocated resources. Separate TCP/IP stack processors can be provided for each of multiple tenants on the host. Separate loopback interfaces of multiple TCP/IP stack processors can be used to create separate containment for separate sets of processes on a host.

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.
