Materials and agenda for path validation side meeting

Repo for the NASR Side Meeting at IETF 119

Time

Wednesday 6:30PM - 8:00PM, March 20th, Room P6-7

About

The goal of NASR is to achieve secure routing by ensuring data transits only on trusted devices, trusted links, trusted operating environments or trusted services.

Problem Statement: Traditional routing security does not guarantee predictability and auditability of forwarding behaviors.

Motivation: Security-sensitive clients want their sensitive data forward only via trusted devices, with no data leakage or deviation from these predictable paths.

Use Cases: This permits operator use cases such as (differentiated trust-level) secure leased lines, quality of trust, routing compliance services, SFC, etc.

See initial charter/scope in our opening/host slides...

NASR continues the discussion from IETF 118 Path Validation Side Meeting, whose agenda and materials are also archived in this repo.
