Title : IPsec Gateway Failover and Redundancy Protocol
Author(s) : L. Dondeti, V. Narayanan
Filename : draft-dondeti-ipsec-failover-sol-00.txt
Pages : 25

IPsec gateways and servers maintaining SAs with large number of
clients can quickly recover from failover using the protocols and
procedures specified in this document. These techniques also
facilitate IPsec clients to move from one gateway to another and
resume operation without having to rerun IKEv2. The idea is to
maintain IKEv2 and IPsec SA state at either the client or one or more
backup servers to reduce the communication and computation overhead
associated with reestablishing the SAs from scratch. Client to
server SA state storage retrieval mechanisms and client-initiated or
server-initiated failover recovery protocols are specified. This
document, however, does not define an inter-gateway transport
mechanism to transfer the state across entities at the backend.

In the body type:

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
