Abstract: Techniques for management of traffic in a network. The techniques provide application awareness in a Network Address Translation (NAT) system. In some examples, a first traffic is received at a first switch in a network from a first application hosted behind the first switch. The first switch identifies a first resource tag associated with the application from the first traffic. Further, the first switch identifies a first rule from the first resource tag indicating that the first traffic is to be routed through an intermediate device that performs network address translation. Moreover, the first switch transmits the traffic to an intermediate device, which perform NAT to translate the source IP address of the first traffic to a second IP address. Finally, the intermediate device sends the traffic to a destination device indicated by the first traffic.
