摘要:
Some embodiments provide a non-transitory machine readable medium of a controller of a network control system for configuring a wide area network (WAN) optimizer instance to implement a WAN optimizer for a logical network. The controller receives a configuration for the WAN optimizer to optimize network data from the logical network for transmission to another WAN optimizer. The controller identifies several other controllers in the network control system on which to implement the logical network. The controller distributes the configuration for implementation on the WAN optimizer.

Some embodiments provide a system for implementing a logical network that includes a set of end machines, a first logical middlebox, and a second logical middlebox connected by a set of logical forwarding elements. The system includes a set of nodes. Each of several nodes includes (i) a virtual machine for implementing an end machine of the logical network, (ii) a managed switching element for implementing the set of logical forwarding elements of the logical network, and (iii) a middlebox element for implementing the first logical middlebox of the logical network. The system includes a physical middlebox appliance for implementing the second logical middlebox.

A gateway is provided that handles traffic in and out of a network by using a datapath pipeline. The datapath pipeline includes multiple stages for performing various data-plane packet-processing operations at the edge of the network. The processing stages include centralized routing stages and distributed routing stages. The processing stages can include service-providing stages such as NAT and firewall. The gateway caches the result previous packet operations and reapplies the result to subsequent packets that meet certain criteria. For packets that do not have applicable or valid result from previous packet processing operations, the gateway datapath daemon executes the pipelined packet processing stages and records a set of data from each stage of the pipeline and synthesizes those data into a cache entry for subsequent packets.

Some embodiments provide a method for configuring a logical middlebox in a hosting system that includes a set of nodes. The logical middlebox is part of a logical network that includes a set of logical forwarding elements that connect a set of end machines. The method receives a set of configuration data for the logical middlebox. The method uses a stored set of tables describing physical locations of the end machines to identify a set of nodes at which to implement the logical middlebox. The method provides the logical middlebox configuration for distribution to the identified nodes.

Some embodiments provide a novel network control system for managing a set of switching elements in a network. The network control system includes a first set of network controllers for managing a first set of switching elements that enable communication between a first set of machines. The network control system includes a second set of network controllers for managing a second set of switching elements that enable communication between a second set of machines. The second set of switching elements is separate from the first set of switching elements and the second set of machines is separate from the first set of machines. The network control system includes a third set of network controllers for managing the first and second sets of network controllers in order to enable communication between machines in the first set of machines and machines in the second set of machines.
摘要:
Some embodiments provide a method for a first network controller that manages a logical network implemented in a datacenter including forwarding elements to which the first network controller does not have access. The method identifies a first data compute node (DCN) in the datacenter configured to execute a second network controller. The method distributes configuration data defining the logical network to the first DCN. The second network controller distributes sets of the configuration data to local agents executing on additional DCNs in the datacenter that send and receive messages through the logical network. Both managed forwarding elements and the local agents execute on each of the additional DCNs. Each local agent on a particular DCN is for receiving a set of configuration data from the second network controller and configuring the managed forwarding element on the particular DCN to implement the logical network according to the set of configuration data.
