Summary:A system, method and apparatus for communication is provided which includes maintaining a primary and a secondary network media devices at substantially similar encryption state, wherein the secondary network media device is a redundant network media device Similar encryption state may be maintained by copyjng reception and transmission switchover parameters from the primary network media device to the redundant network media device, at least once per 2 N packets, and preferably every 2 m packets that are either transmitted by, or received at, the primary network media device. The redundant network media device may receive packets by utilizing copied reception switchover parameters and transmit packets by estimating transmission switchover parameters based on copied transmission switchover parameters. The reception and transmission switchover parmaeters may be associated with Secure Real-time Transport Protocol or with PacketCable protocol. A communication system is also provided, which utilizes the communica
