Systems and methods for integrating a device with a software-defined networking controller
The disclosure is directed towards systems and methods for integrating a device with a software-defined networking (SDN) controller. A device intermediary to a plurality of clients and a plurality of servers can receive a request to establish a communicative connection between an SDN controller and the device. The request can be based on a device package including a device model, a device script configured to integrate the device with the SDN controller and including one or more function call definitions, a functional profile including a default value for at least one parameter of the device, and a plurality of device-level configuration parameters specifying values of parameters utilized by the device. The device can receive a request to configure one or more functions of the device. The request can configure the functions generated by the SDN controller based on the device package.

5. The method of claim 1 , wherein receiving a request to configure a function of the device comprises receiving a request to configure at least one of the following functions associated with communications between the plurality of clients and the plurality of servers:
(a) authentication, authorization, and auditing (AAA);
(b) an application firewall;
(c) cache redirection;
(d) compression;
(e) content acceleration;
(f) content switching;
(g) DataStream;
(h) domain name service;
(i) dynamic routing;
(j) global server load balancing;
(k) integrated caching;
(l) load balancing;
(m) secure sockets layer (SSL) offload;
(n) SSL virtual private networking (VPN); and
(o) network address translation (NAT).
6. The method of claim 1 , wherein the device package is configured to allow the SDN controller to configure a function of the device via a graphical user interface (GUI).
7. The method of claim 6 , wherein the GUI includes a service graph, the service graph including a set of function nodes between the SDN controller and the device, the set of function nodes identifying a set of network service functions used by an application communicating with the SDN controller.
8. The method of claim 1 , wherein the device comprises an application delivery controller (ADC).
9. The method of claim 1 , wherein the device and the SDN controller are deployed in a datacenter network.
10. A system for integrating a device with a software-defined networking (SDN) controller, comprising:
a device intermediary to a plurality of clients, a plurality of servers, and an SDN controller, the device configured to:
receive a request to establish a communicative connection between a software-defined networking (SDN) controller and the device, the request to establish the communicative connection based on a device package specific to the device including a device model, a device script configured to integrate the device with the SDN controller and including one or more function call definitions, a functional profile including a default value for at least one parameter of the device, and a plurality of device-level configuration parameters specifying values of parameters utilized by the device; and
receive a request to configure one or more functions of the device, the request to configure the functions of the device generated by the SDN controller via the device script of based on the device package, the request having a format specified by the device model and including values of parameters selected by the SDN controller using the device-level configuration parameters corresponding to the functions of the device to be configured, the device configuring the one or more functions responsive to receiving the request to configure the functions of the device; and
wherein the device model comprises information relating to functions provided by the device to the SDN controller and configuration parameters of the functions provided by the device to the SDN controller.
11. The system of claim 10 , further comprising:
configuring a management Internet protocol (IP) address and a management virtual local area network (VLAN) of the device; and
specifying a default gateway on the device.
12. The system of claim 10 , further comprising configuring the device for management access by the SDN controller via a user interface provided by the device.
13. The system of claim 10 , wherein the device package is configured to allow the SDN controller to configure functions of the device via a representation state transfer (REST)-based application programming interface (API).
14. The system of claim 10 , wherein the request to configure a function associated with the device comprises a request to configure at least one of the following functions associated with communications between the plurality of clients and the plurality of servers:
(a) authentication, authorization, and auditing (AAA);
(b) an application firewall;
(c) cache redirection;
(d) compression;
(e) content acceleration;
(f) content switching;
(g) DataStream;
