    Abstract: Some embodiments of the invention provide novel methods for providing transparent services for multicast data messages traversing a network edge device operating at a boundary between two networks. The method analyzes data messages received at the network edge device to determine whether they require a service provided at the boundary and whether they are unicast or multicast (including broadcast). The method modifies a multicast destination media access control (MAC) address of a multicast data message requiring a service to be a unicast destination MAC address and provides, without processing by a standard routing function, the modified data message directly to an interface associated with a service node that provides the particular service required by the data message. The method receives the serviced data message, restores the multicast destination MAC address, and forwards the serviced data message to a set of destinations associated with the multicast destination address.

    Abstract: Some embodiments provide novel methods for providing a set of services for a logical network associated with an edge forwarding element acting between a logical network and an external network. In some embodiments, the services are provided using a logical service forwarding plane that connects the edge forwarding element to a set of service nodes that each provide a service in the set of services. The service classification operation of some embodiments identifies a chain of multiple service operations that has to be performed on the data message. In some embodiments, identifying the chain of service operations includes selecting a service path to provide the multiple services. After selecting the service path, the data message is sent along the selected service path to have the services provided. The data message is returned to the edge forwarding element by a last service node in the service path that performs the last service operation and the edge forwarding element performs next hop forwarding on the data message.

    Abstract: Some embodiments provide novel methods for providing different types of services for a logical network associated with an edge forwarding element acting between the logical network and an external network. The edge forwarding element receives data messages for forwarding and performs a service classification operation to select a set of services of a particular type for the data message. The particular type of service is one of multiple different types of services that use different transport mechanisms to forward the data to a set of service nodes (e.g., service virtual machines, or service appliances, etc.) that provide the service. The edge forwarding element then receives the data message after the selected set of services has been performed and performs a forwarding operation to forward the data message. In some embodiments, the method is also performed by edge forwarding elements that are at the edges of logical network segments within the logical network.

    Abstract: Some embodiments configure an edge forwarding element to perform service insertion operations to identify stateful services to perform for data messages received for forwarding by the edge forwarding element at multiple virtual interfaces of the edge forwarding element. The service insertion operation, in some embodiments, includes applying a set of service insertion rules. The service insertion rules (1) specify a set of criteria and a corresponding action to take for data messages matching the criteria and (2) are associated with a set of interfaces to which the service insertion rules are applied. In some embodiments, the action is specified using a universally unique identifier (UUID) that is then used as a matching criteria for a subsequent policy lookup that identifies a type of service insertion and a set of next hop data.

    Abstract: Some embodiments provide novel methods for performing services for machines operating in one or more datacenters. For instance, for a group of related guest machines (e.g., a group of tenant machines), some embodiments define two different forwarding planes: (1) a guest forwarding plane and (2) a service forwarding plane. The guest forwarding plane connects to the machines in the group and performs L2 and/or L3 forwarding for these machines. The service forwarding plane (1) connects to the service nodes that perform services on data messages sent to and from these machines, and (2) forwards these data messages to the service nodes. In some embodiments, the guest machines do not connect directly with the service forwarding plane. For instance, in some embodiments, each forwarding plane connects to a machine or service node through a port that receives data messages from, or supplies data messages to, the machine or service node. In such embodiments, the service forwarding plane does not have a port that directly receives data messages from, or supplies data messages to, any guest machine. Instead, in some such embodiments, data associated with a guest machine is routed to a port proxy module executing on the same host computer, and this other module has a service plane port. This port proxy module in some embodiments indirectly can connect more than one guest machine on the same host to the service plane (i.e., can serve as the port proxy module for more than one guest machine on the same host).

    Abstract: Example methods and systems for connectivity check with service insertion have been disclosed. One example may comprise a computer system receiving a connectivity check packet that is injected for forwarding along a service path between a source virtualized computing instance and a destination virtualized computing instance. In response to detecting a connectivity issue associated with the service path, first report information identifying the first service virtualized computing instance and an observation that the connectivity check packet is dropped may be generated and sent. Otherwise, the connectivity check packet may be forwarded towards a second virtualized computing instance, being a next-hop on the service path, or the destination virtualized computing instance. Second report information identifying the first service virtualized computing instance and an observation that the connectivity check packet is forwarded may be generated and sent.
