摘要： 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.

摘要： 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.

摘要： Described herein are systems and methods to manage Internet Protocol (IP) address discovery in a software defined networking (SDN) environment. In one example, a manager may generate an IP address discovery configuration and pass the IP address discovery configuration to a controller. Once received, the controller may obtain a discovered list from a hypervisor of one or more IP addresses associated with one or more logical ports and update a realized list for the one or more logical ports based on the discovered list and the IP address discovery configuration.

摘要： 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.

摘要： 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).

摘要： 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.

摘要： 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: determining, at an egress interface of a host that hosts a virtual machine (“VM”), whether a service plane MAC address (“spmac”) in a packet header of a packet, provided to the egress interface, is the same as an inner destination MAC address in the packet; in response to determining that the spmac in the packet header of the packet, provided to the egress interface, is the same as the inner destination MAC address in the packet: encapsulating the packet with a destination virtual tunnel endpoint (“VTEP”) address retrieved from a mapping of VTEP-labels onto VTEP addresses; and causing providing the packet from the egress interface of the host that hosts the VM to a source host that hosts a source guest virtual machine (“GVM”).

摘要： Some embodiments provide policy-driven methods for deploying edge forwarding elements in a public or private SDDC for tenants or applications. For instance, the method of some embodiments allows administrators to create different traffic groups for different applications and/or tenants, deploys edge forwarding elements for the different traffic groups, and configures forwarding elements in the SDDC to direct data message flows of the applications and/or tenants through the edge forwarding elements deployed for them. The policy-driven method of some embodiments also dynamically deploys edge forwarding elements in the SDDC for applications and/or tenants after detecting the need for the edge forwarding elements based on monitored traffic flow conditions.

摘要： Some embodiments provide a method for forwarding multicast data messages at a forwarding element on a host computer. The method receives a multicast data message from a routing element executing on the host computer along with metadata appended to the multicast data message by the routing element. Based on a destination address of the multicast data message, the method identifies a set of recipient ports for a multicast group with which the multicast data message is associated. For each recipient port, the method uses the metadata appended to the multicast data message by the routing element to determine whether to deliver a copy of the multicast data message to the recipient port.

摘要： Described herein are systems and methods to manage blacklists and duplicate addresses in software defined networks (SDNs). In one implementation, a method includes, in a control plane and data plane of an SDN environment, obtaining a blacklist for a logical port in the SDN environment. The method further includes deleting realized address bindings in a realized address list for the logical port that match the one or more address bindings in the blacklist and preventing subsequent address bindings that match the one or more address bindings in the blacklist from being added to the realized address list.
