 Generalized TTL security mechanism

The Generalized TTL Security Mechanism (GTSM) is a proposed Internet data transfer security method relying on a packet's Time to Live (IPv4) or Hop limit (IPv6) thus to protect a protocol stack from spoofing and denial of service attacks.The desired purpose of this proposal is to verify whether the packet was originated by an adjacent node and to protect router infrastructure from overload-based attacks.
