The Generalized TTL Security Mechanism
RFC 5082, “The Generalized TTL Security Mechanism”, is a Proposed Standard document published in October 2007 by V. Gill, J. Heasley, D. Meyer, P. Savola, C. Pignataro. It obsoletes RFC 3682. The canonical text is published by the RFC Editor.
Abstract
The use of a packet's Time to Live (TTL) (IPv4) or Hop Limit (IPv6) to verify whether the packet was originated by an adjacent node on a connected link has been used in many recent protocols. This document generalizes this technique. This document obsoletes Experimental RFC 3682. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
The canonical text of RFC 5082 is hosted at rfc-editor.org. Available in TXT,HTML.
