Abstract: An example method of file transfer between a client and a server includes: initiating, by the client, a front-end control connection between the client and a horizontally scaled proxy service; creating, by a first proxy instance of a plurality of proxy instances of the horizontally scaled proxy service, a back-end control connection between the first proxy instance and the server; returning, to the client from the first proxy instance, a unique client parameter associated with the front-end connection as a destination port for a front-end data connection; initiating, by the client, the front-end data connection between the client and the horizontally scaled proxy service, the front-end data connection using the destination port as returned by the first proxy instance; and creating, by the first proxy instance, a back-end data connection between the first proxy instance and the server.

Abstract: Some embodiments provide a method of performing load balancing on client traffic sent to a cluster of servers that are associated with a common network address (e.g., for a VIP address associated with a service provided by the cluster of servers). The method assigns a cluster of two or more transparent load balancers to the common network address associated with the server cluster. The method configures at least two of these transparent load balancers as active transparent load balancers that concurrently (1) receive data message flows sent by clients directed to the common network address, (2) select one of the servers for each flow, and (3) forward each flow to the server selected for the flow without modifying a source network address (e.g., IP network address) of the flow.

Abstract: Some embodiments provide a novel method for performing network address translation to share a limited number of external source network addresses among a large number of connections. Instead of allocating an external source network address for an egressing packet just based on its internal source network address, the method of some embodiments allocates the external source network address based on the egressing packet's source network address and destination network address. This allows a limited number of external source network addresses to be re-used for different destination network address. For instance, in some embodiments, the method's network address allocation scheme allows the same 64K (e.g., 2{circumflex over (?)}16) external source ports to be used for 64K connections for each destination network address.

Abstract: Some embodiments provide a method for generating a test traffic configuration for testing a first network. From a second network, the method receives a set of data streams representing data traffic observed in the second network. The method uses a machine learning engine to analyze the set of data streams in order to determine traffic patterns in the second network. The method generates the test traffic configuration for testing the first network by replicating the traffic patterns of the second network in the first network.
