The Generalized TTL Security Mechanism (GTSM) describes a generalized
use of a packets Time to Live (TTL) (IPv4) or Hop Limit (IPv6) to
verify that the packet was sourced by a node on a connected link,
thereby protecting the router's IP control-plane from CPU utilization
based attacks. This technique improves security and is used by many
protocols. This document defines the GTSM use for Label Distribution
Protocol (LDP).
