A PCE-Based Framework for Future Internet Deterministic and Time-Sensitive Networks

Abstract

Deterministic and time-sensitive networking will be critical for enabling ultra-reliable low latency communication (URLLC) networks and services. However, limitations exist for using traditional IP technologies and current Internet architecture, for deterministic and time-sensitive networking. The emerging URLLC network types and traffic types require new fundamental cornerstones that include deterministic behaviour, real-time sensitivity, and capable of being highly resilient to network infrastructure failures. Various technologies exist with the current Internet to provide limited capabilities for each primitive. However, fully achieving the URLLC objectives will require a radical approach that moves beyond current network design and Internet architecture.This paper proposes a new approach and architecture for extending the data plane and control plane elements for future URLCC requirements. It provides a summary of applicable transport, control and service layers. How existing functions and mechanisms will need to be extended and combined to meet the future demands of Future Internet networks and services. Finally, the paper provides a theoretical PCE-based framework for future deterministic and time-sensitive networks, and the protocol work required to standardize and deploy.
