This document defines an integrity transform for Secure Real-time
Transport Protocol (SRTP; see RFC 3711), which allows the roll-over
counter (ROC) to be transmitted in SRTP packets as part of the
authentication tag. The need for sending the ROC in SRTP packets
arises in situations where the receiver joins an ongoing SRTP session
and needs to quickly and robustly synchronize. The mechanism also
enhances SRTP operation in cases where there is a risk of losing sender-receiver synchronization. [STANDARDS TRACK]
