Network Service Type-Aware Traffic Labeling Protocol (NST-TLP)

This document specifies a protocol mechanism for embedding service type identifiers into network packets in order to enable intelligent traffic recognition, policy-based forwarding, and resource optimization by network devices. The protocol allows standardized service type labels to be carried in IPv4/IPv6 headers, MPLS labels, or Ethernet frame headers. It is applicable to a wide range of services, including immersive VR (e.g., 1080p, 4K), scientific computing, real-time communications, and Internet of Things (IoT) applications.
