Understanding the Metaverse from a Network Access Perspective and Its Implications for Network Technology

Recent hype around the "Metaverse" has prompted the author, a network engineer, to explore its definition and technical implications. Citing Alibaba DAMO‑XR’s description, the Metaverse is viewed as the internet built on VR/AR glasses, extending the evolution from PCs to smartphones to three‑dimensional head‑mounted displays.

The internet’s infrastructure consists of three layers: terminal access, autonomous networking, and heterogeneous interconnection. Terminal access evolves fastest, and each major shift (PC → smartphone → VR/AR) has driven new application revolutions. VR/AR glasses, as three‑dimensional communication‑type terminals, represent the next milestone.

Beyond communication‑type terminals, the author classifies access devices into three categories: communication‑type (human‑centric), computing‑type (servers and compute nodes), and functional‑type (smart cars, industrial control, IoT). Each category imposes distinct network requirements.

From a network‑technology standpoint, the Metaverse introduces new demands: higher bandwidth, stricter latency (sub‑10 ms for immersive interaction), and stronger security for virtual‑physical integration. Existing internet designs—open traffic, store‑and‑forward routing, and statistical multiplexing—conflict with these requirements.

The author outlines three major challenges: (1) Trustworthiness for virtual‑physical fusion, which clashes with the internet’s distributed, open architecture; (2) Ultra‑low latency, hindered by congestion, store‑and‑forward processing, and physical propagation limits; (3) Deterministic QoS, which opposes the internet’s fairness and statistical sharing principles. Potential solutions include distributed trust mechanisms, advanced traffic engineering, edge computing, protocol innovations (e.g., RDMA, QUIC), and governance frameworks.

In conclusion, the Metaverse represents a significant upgrade of internet applications driven by three‑dimensional terminals, likely to trigger another industry reshuffle similar to the mobile‑internet transition, and will push network infrastructure to meet higher security, latency, and reliability standards.
