Title : IPsec Gateway Failover and Redundancy - Problem Statement and Goals
Author(s) : V. Narayanan
Filename : draft-vidya-ipsec-failover-ps-01.txt
Pages : 10

Recovering from failure of IPsec gateways maintaining large numbers
of SAs may take several minutes, if they need to re-establish the
IPsec SAs by re-running the key management protocol, IKEv2. A
similar problem arises in the event of a network outage resulting in
the failure of several gateways and servers. The latency involved in
this approach is significant, leading to a need for a faster and yet
secure failover solution. This document describes the problem
statement and the goals for an IPsec/IKEv2 gateway failover/
redundancy solution.

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.
