A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Service Function Chaining WG of the IETF. Title : Proof of Transit Authors : Frank Brockners Shwetha Bhandari Tal Mizrahi Sashank Dara Stephen Youell Filename : draft-ietf-sfc-proof-of-transit-07.txt Pages : 31 Date : 2020-10-25 Abstract: Several technologies such as Traffic Engineering (TE), Service Function Chaining (SFC), and policy based routing are used to steer traffic through a specific, user-defined path. This document defines mechanisms to securely prove that traffic transited a defined path. These mechanisms allow to securely verify whether, within a given path, all packets traversed all the nodes that they are supposed to visit. The document defines the data model through Unified Modeling Language (UML) class diagrams and formally specifies it using an NDMA- compliant YANG model to enable these mechanisms.
