Abstract: In one embodiment, a method for the prioritized transmission of messages includes monitoring a network link of a mobile device to determine performance characteristics of the network link, establishing a network association between the mobile device and a routing network node, receiving a connection request from an application that is directed to a connection between the mobile device and a destination server, determining a relative priority of the connection, mapping the connection to a stream of the network association that is associated with the relative priority of the connection and identifies the destination server, and transmitting messages for the stream to the routing network node interlaced with messages of other streams of the network association based on the performance characteristics of the network link and the relative priority associated with the stream in comparison to relative priorities associated with the other streams of the network association.

Abstract: In one embodiment, a device in a network captures domain name system (DNS) response data from a DNS response sent by a DNS service to a client in the network. The device captures session data for an encrypted session of the client. The device makes a determination that the encrypted session is malicious by using the captured DNS response data and the captured session data as input to a machine learning-based or rule-based classifier. The device performs a mediation action in response to the determination that the encrypted session is malicious.
