1. A network transmission interface, comprising:
a transmission media access control (MAC) unit configured to receive data frames at a variable bitrate, encapsulate the data frames, and output the encapsulated data frames at a constant bitrate;
a timestamp unit configured to insert timestamps in payloads of the data frames; and
a MAC layer security unit located downstream from the transmission MAC unit.
