Clock correlation can be achieved, for example, utilizing the RTP stream between a sender and receiver by determining a baseline at the start of, for example, a communication. This baseline is derived as a point in time from an arriving packet and represents a point from which subsequent packets deviate. Using this baseline, an early packet or a late packet can be detected. An early packet pushes the baseline down to that earlier point, while late arriving packets, if they are arriving late for a continuous period of time, represents a shift in the opposite direction from the baseline, resulting in a baseline moving to the 'earliest' packet out of the sequence of the late arriving packets.

The present invention is directed, in various embodiments, to a hardware supported duplication token for arbitrating active and standby module states, a weighted state of health exchange for identifying unhealthy module states and relative module health states, and a packet sequence number synchronization technique for maintaining desired levels of synchronization between the active and standby modules.
