Systems and methods for provisioning network automation by logically separating L2-L3 entities from L4-L7 entities using a software defined network (SDN) controller

A method for providing network models and network configurations for communications, the method comprising:

• establishing, by a device intermediary to a plurality of clients and one or more servers, a first interface on a manager of the device for delivering a network model of the device from the manager of the device to a software defined network (SDN) controller of an SDN;
• providing, by the device to the SDN controller, via the first interface, the network model configured to provide definitions of one or more network layer entities of the device that are configured to provide network layer services;
• establishing, by the device, a second interface on the manager of the device configured to transmit and receive communications between the device and the SDN controller;
• and
• receiving, by the manager of the device via the second interface, network configuration to configure the device to process SDN application requests received from the SDN controller, the network configuration established using the network model provided by the device to the SDN controller.
