Fine-grained QoE Enhancement using Semantic Tables

This document describes a fine-grained Quality of Experience (QoE) enhancement mechanism using semantic tables deployed at network forwarding nodes. The mechanism enables application-level SLA (Service Level Agreement) guarantees by carrying address indices and high-frequency-changing information in packets while maintaining low- frequency-changing semantic information at network nodes. This approach overcomes the limitations of traditional Application-aware Networking (APN) solutions, including excessive packet header overhead. The mechanism supports collaborative optimization across network, computing, and energy dimensions, and can be deployed over MPLS, IPv4/v6, SRv6, and other protocol data planes.
