Abstract

   Deterministic Networking (DetNet) services are expected to be
   integrated with VPN technologies.  Such deployment scenarios include
   mobile backhauls and TSN islands inter-connections.  This document
   describes an overall VPN framework that provides deterministic
   transport services (called deterministic VPN), specifies
   corresponding control and data plane protocols that are required to
   support the framework, and initially summarizes potential extensions
   of existing protocols to enable deterministic VPNs.

1.  Introduction

   Deterministic Networking (DetNet) aims to provide bounded latency
   transport as well as low data loss rate for specific data flows over
   layer-3 networks [arch].  Potential use cases include electrical
   utilities, building automation systems, and industrial machine to
   machine [use-case].  From the perspective of real-world deployment,
   DetNet services are expected to be integrated with VPN technologies,
   e.g., MPLS/IP VPN, E-VPN.  In particular, one or more VPN instances
   of an ISP network are required to provide bounded latency and low
   data loss rate transmission services for the customers.  Such
   deployment scenarios include mobile backhauls and TSN islands inter-
   connections.

   This document presents an overall VPN framework that provides
   deterministic transport services (called deterministic VPN),
   specifies corresponding control and data plane protocols that are
   required to support the framework, and initially summarizes potential
   extensions of existing protocols to enable deterministic VPNs.  Note
   that specific extensions of existing protocols will be defined by
   separated documents.
