    Abstract: In an embodiment, a computer-implemented method provides mechanisms for identifying a source location in a service chaining topology. In an embodiment, a method comprises: receiving a query, from a service plane implementation module executing on a host of a service virtual machine (“SVM”), for a location of a source host implementing a guest virtual machine (“source GVM”) that originated a packet in a computer network and that serviced the packet; in response to receiving the query, performing a search of bindings associated with one or more virtual network identifiers (“VNIs”) or service virtual network identifiers (“SVNIs”) to identify a particular binding that includes a MAC address of the host implementing the source GVM; identifying, in the particular binding, the location of the source host; and providing the location of the source host to the host of the SVM to facilitate forwarding of the packet from the SVM to the GVM.

    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: A method for a parallel execution of services, of a serial service chain, on packets using multicast-based service insertion is disclosed. In an embodiment, a method comprises detecting a packet of a data flow and storing the packet in memory. From a plurality of multicast groups, a first multicast group is identified. The first multicast group includes a plurality of service machines configured to provide a plurality of services to the data flow. The first multicast group includes all services machines of the plurality of service machines. The packet is multicast to the first multicast group of the plurality of multicast groups to cause applying, in parallel, services of service machines included in the first multicast group. Upon receiving a plurality of responses from service machines of the first multicast group, the plurality of responses is analyzed to determine whether the plurality of responses includes a modify-response. In response to determining that the plurality of responses does not include any modify-response, the plurality of responses is analyzed to determine whether the plurality of responses includes a drop-response. In response to determining that the plurality of responses does not include any drop-response, the packet is forwarded toward its destination without multicasting the packet to any other multicast group of the plurality of multicast groups.

    Abstract: A method for creating a set of virtual machines on a public datacenter. The method, from a first network controller of a private network, commands a second network controller of the public datacenter to create the virtual machines. The method, from the first network controller of the private network, communicates with the second network controller of the public datacenter to determine a type of the second network controller. When the first network controller includes instructions for using application programming interfaces (APIs) of the type of the second network controller, the method uses the APIs to set up a VLAN for the set of virtual machines in order to allow the virtual machines of the set of virtual machines to communicate securely with each other without sending the communications through the private network. In some embodiments, the VLAN is a private VLAN (PVLAN).

    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.
