Title : The Generalized TTL Security Mechanism (GTSM)

The use of a packet's TTL to protect a protocol stack from
CPU-utilization based attacks has been proposed in many
settings (see for example, RFC 2461 [RFC2461]). This document
generalizes these techniques for use by other protocols such
as BGP [RFC1771], MSDP [MSDP], Bidirectional Forwarding
Detection [BFD], and LDP [LDPHELLO]. While the Generalized TTL
Security Mechanism (GTSM) is most effective in protecting
directly connected protocol peers, it can also provide a lower
level of protection to multi-hop sessions. Use of multi-hop
GTSM should be considered on a case-by-case basis.

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.
