Abstract: Disclosed herein are systems and methods for multi-level classification of data traffic flows based on information in a first packet for a data traffic flow. In exemplary embodiments of the present disclosure, a key can be generated from intercepted DNS data to track data traffic flows by application names and destination IP addresses. Based on these keys, patterns can be discerned to infer data traffic information based on only the information in a first packet, such as destination IP address. The determined patterns can be used to predict classifications of future traffic flows with similar key information. In this way, data traffic flows can be classified and steered in a network based on limited information available in a first packet.

Abstract: Disclosed herein are systems and methods for detection of a path break in a communication network by one network appliance of a plurality of network appliance. A communication path that is transitioning from active to idle state can be quickly determined by evaluating network data traffic within a predetermined time interval after the end of a data transmission.

Further, the path break condition can be determined unilaterally by one network appliance.
