Abstract
This specification describes technologies relating to imparting real-time priority-based network communications in an encrypted session. In general, aspects of the subject matter described can be embodied in methods that include establishing, based on cryptographic information in a reserved, random-data portion of a handshake communication, a session, receiving parameter values relating to a sub media stream, included in a header of a network communication, storing the parameter values, obtaining state information and a data payload included in a second network communication, identifying, from the state information, a purpose of the second network communication, and whether a header of the second network communication includes one or more new values corresponding to one or more of the parameters, updating one or more of the stored values based on the one or more new values, and processing the data payload based on the identified purpose and the stored parameter values.
