    Abstract: A novel method of conducting multicast traffic in a network is provided. The network includes multiple endpoints that receive messages from the network and generate messages for the network. The endpoints are located in different segments of the network, each segment including one or more of the endpoints. For a source endpoint to replicate a particular message (e.g., a data packet) for all endpoints belonging to a particular replication group (i.e., multicast group) within the network, the source endpoint replicates the particular message to each endpoint within the source endpoint's own segment and to a proxy endpoint in each of the other segments. Each proxy endpoint in turn replicates the particular message to all endpoints belonging to the particular replication group within the proxy endpoint's own segment.

    Abstract translation: 提供了一种在网络中进行组播流量的新颖方法。 网络包括从网络接收消息并为网络生成消息的多个端点。 端点位于网络的不同段中，每个段包括一个或多个端点。 对于源端点来复制属于网络内特定复制组（即多播组）的所有端点的特定消息（例如，数据包），源端点会将特定消息复制到源端点自身的每个端点 段和每个其他段中的代理端点。 每个代理端点反过来将特定消息复制到属于代理端点自身段内特定复制组的所有端点。

    Abstract: 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.

    Abstract translation: 提供了具有用于将来自物理主机（PH）到逻辑网络的分组路由的多个指定实例的逻辑路由选择元素（LRE）。 具有多个指定实例的网段中的PH可以根据负载平衡算法在多个指定实例中选择，以将网络流量发送到逻辑网络中的其他网络节点。 LRE的每个逻辑接口（LIF）被定义为可由多个标识符或地址寻址，并且每个LIF标识符或地址被分配给不同的指定实例。

    Abstract: Some embodiments provide a method of operating several logical networks over a network virtualization infrastructure. The method defines a managed physical switching element (MPSE) that includes several ports for forwarding packets to and from a plurality of virtual machines. Each port is associated with a unique media access control (MAC) address. The method defines several managed physical routing elements (MPREs) for the several different logical networks. Each MPRE is for receiving data packets from a same port of the MPSE. Each MPRE is defined for a different logical network and for routing data packets between different segments of the logical network. The method provides the defined MPSE and the defined plurality of MPREs to a plurality of host machines as configuration data.

    Abstract: A novel method for fully utilizing the multicast or broadcast capability of a physical network is provided. The method identifies segments of the network within which broadcast traffic, multicast traffic, or traffic to unknown recipients (BUM traffic) is allowed or enabled. The identified segment encompasses parts of the network that the BUM traffic is able reach while excluding parts of the network nodes that the BUM traffic is unable to reach. Each identified segment includes network nodes that are interconnected by physical network hardware that supports BUM traffic. The method identifies multiple BUM traffic segments in a given network that each supports its own BUM traffic. The different BUM traffic segments are interconnected by physical network hardware that does not support BUM network traffic. Each identified segment is assigned an identifier that uniquely distinguishes the identified segment from other identified segments.

    Abstract: 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.
