    abstract =  {This document describes a method for reducing the size of the Internet Key Exchange version 2 (IKEv2) exchanges at time of rekeying IKE SAs and Child SAs by removing or making optional of SA \& TS payloads. Reducing size of IKEv2 exchanges is desirable for low power consumption battery powered devices. It also helps to avoid IP fragmentation of IKEv2 messages.},
