Abstract:
   Encapsulating Security Payload (ESP) sends an initialization vector
   (IV) or nonce in each packet.  The size of IV depends on the applied
   transform, being usually 8 or 16 octets for the transforms defined by
   the time this document is written.  Some algorithms such as AES-GCM,
   AES-CCM, AES-CTR and ChaCha20-Poly1305 require a unique nonce but do
   not require an unpredictable nonce.  When using such algorithms the
   packet counter value can be used to generate a nonce.  This avoids
   sending the nonce itself, and saves in the case of AES-GCM, AES-CCM,
   AES-CTR and ChaCha20-Poly1305 8 octets per packet.  This document
   describes how to do this.
