    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: 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.
