  • Patent number: 11729090
    Abstract: Disclosed herein are systems and methods for multi-level classification of data traffic flows based on information in a first data packet for a data traffic flow. In exemplary embodiments of the present disclosure, a key can be generated to track data traffic flows by application names and data packet information or properties. Based on these keys, patterns can be discerned to infer data traffic information based on only the information in a first data packet. 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 data packet.

  • Patent number: 11424857
    Abstract: Disclosed herein are systems and methods for forward packet recovery in a communication network with constrained network bandwidth overhead. In exemplary embodiments, a target byte protection ratio is determined. Error correcting frames are dynamically generated by a first processor such that error correcting information can be generated to approximate the target byte protection ratio. The data packets and error correcting information are then transmitted across one or more communication networks to a second processor. The second processor can use the error correcting information to regenerate or replace data packets missing or corrupted in transmission across one or more communication networks.

  • Patent number: 11405265
    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. By strategically utilizing health probes at only a set predetermined time interval after a data transmission, a path break condition can be quickly determined without significant use of network bandwidth. Further, the path break condition can be determined unilaterally by one network appliance.
