Abstract:
This document defines two Notify Message Type Payloads for the
Internet Key Exchange Protocol Version 2 (IKEv2) to support the
negotiation of multiple Child SAs with the same Traffic Selectors
used on different resources, such as CPUs, to increase bandwidth of
IPsec traffic between peers.
The SA_RESOURCE_INFO notification is used to convey information that
the negotiated Child SA and subsequent new Child SAs with the same
Traffic Selectors are a logical group of Child SAs where most or all
of the Child SAs are bound to a specific resource, such as a specific
CPU. The TS_MAX_QUEUE notify conveys that the peer is unwilling to
create more additional Child SAs for this particular negotiated
Traffic Selector combination.
Using multiple Child SAs with the same Traffic Selectors has the
benefit that each resource holding the Child SA has its own Sequence
Number Counter, ensuring that CPUs don't have to synchronize their
cryptographic state or disable their packet replay protection.
