Abstract:
The Internet Key Exchange protocol version 2 (IKEv2) can operate
either over unreliable (UDP) transport or over reliable (TCP)
transport. If TCP is used, then IPsec tunnels created by IKEv2 also
use TCP. This document specifies how to decouple IKEv2 and IPsec
transports so that IKEv2 can operate over TCP, while IPsec tunnels
use unreliable transport. This feature allows IKEv2 to effectively
exchange large blobs of data (e.g., when post-quantum algorithms are
employed) while avoiding performance problems that arise when IPsec
uses TCP.
