Abstract

A device may receive policy information associated with a first application group and a second application group. The device may receive network topology information associated with a network. The device may generate a first policy based on the policy information and the network topology information, and generate a second policy based on the policy information and the network topology information. The device may provide, to the virtual network device, information associated with the first policy to permit the virtual network device to implement the first policy in association with network traffic transferred between the first application group and the second application group. The device may provide, to the physical network device, information associated with the second policy to permit the physical network device to implement the second policy in association with network traffic transferred between the first application group and the second application group.
