    Abstract: Some embodiments provide a method of multicasting data in a segregated logical network with multiple network segments. The network segments each have at least one router. The multicast originates from a multicast source in a first network segment and goes to multicast receivers in several other network segments. In the method, the router of the first network segment receives encoding data for a set of virtual tunnel endpoints (VTEPs) of the receivers. The router then receives the multicast data from the multicast source. For each VTEP, the router then encodes the data for the receiver using the encoding data for the VTEP of the receiver. The router then sends (e.g., as a unicast) the encoded data to a router of the network segment of the receiver. The router performing the method may be a domain router of the network segment of the receiver.

    Abstract: Example methods and systems for virtual tunnel endpoint (VTEP) mapping for overlay networking are described. One example may involve a computer system monitoring multiple VTEPs that are configured for overlay networking. In response to detecting a state transition associated with a first VTEP from a healthy state to an unhealthy state, the computer system may identify mapping information that associates a virtualized computing instance with the first VTEP in the unhealthy state; and update the mapping information to associate the virtualized computing instance with a second VTEP in the healthy state. In response to detecting an egress packet from the virtualized computing instance to a destination, an encapsulated packet may be generated and sent towards the destination based on the updated mapping information. The encapsulated packet may include the egress packet and an outer header identifying the second VTEP to be a source VTEP.

    Abstract: Some embodiments provide a method of forwarding data messages between source and destination host computers that execute source and destination machines. At a source computer on which a source machine for a data message flow executes, the method in some embodiments identifies a source tunnel endpoint group (TEPG) associated with the source machine. For the flow, the method selects one TEP of the TEPG as the source TEP. The method then uses the selected source TEP to forward the flow to the destination computer on which the destination machine executes.

    Abstract: Some embodiments provide a method of replicating messages for a logical network. At a particular tunnel endpoint in a particular datacenter, the method receives a message to be replicated to members of a replication group. The method replicates the message to a set of tunnel endpoints of the replication group located in a same segment of the particular datacenter as the particular tunnel endpoint. The method replicates the message to a first set of proxy endpoints of the replication group, each of which is located in a different segment of the particular datacenter and for replicating the message to tunnel endpoints located in its respective segment of the particular datacenter. The method replicates the message to a second set of proxy endpoints of the replication group, each of which is located in a different datacenter and for replicating the message to tunnel endpoints located in its respective datacenter.

    Abstract: In some embodiments, a method determines when a packet is fragmented into multiple fragmented packets in a flow between a first workload and a second workload. The method switches from generating an outer source port in the outer header using layer 4 information from the inner header to using layer 3 information from the inner header. A fragmented packet is encapsulated with the outer header that includes an outer source port value that is generated using the layer 3 information. The method initiates a process to determine when to switch back to using layer 4 information from the inner header to generate the outer source port. When it is determined to switch back to using layer 4 information, the method switches back to using layer 4 information from the inner header to generate the source port in the outer header of a packet from the first workload.
