The use of a packet's TTL (IPv4) or Hop Limit (IPv6) to protect a
protocol stack from CPU-utilization based attacks has been proposed
in many settings (see for example, RFC 2461). This document
generalizes these techniques for use by other protocols such as BGP
(RFC 1771), MSDP, Bidirectional Forwarding Detection, and LDP (RFC
3036). 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. GTSM
is not directly applicable to protocols employing flooding mechanisms
(e.g., multicast), and 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
