Future Network Architecture and Emerging Data Center Technologies in the New Infrastructure Era

Background

"New infrastructure" refers to the next‑generation foundational facilities characterized by informationization, intelligence, and digitization, including 5G networks, big‑data centers, smart transportation, smart health, industrial Internet, vehicle‑Internet, low‑orbit satellites, new‑energy vehicles and charging piles, and ultra‑high‑voltage power grids. Strengthening these infrastructures is strategically vital for economic development, demand stimulation, and improving people’s lives.

The rapid advancement of big data, cloud computing, and artificial intelligence enables new infrastructure to meet emerging demands, drive consumption upgrades, and foster new industries and services, thereby unlocking economic growth potential.

Internet development over the past 40 years can be divided into two stages: the first 20 years focused on scientific research, while the post‑1990s era saw the Internet permeate all aspects of daily life. The next phase, often called Internet 3.0 or the future network, will deeply integrate with the real economy, with candidate architectures such as Software‑Defined Networking (SDN), Content‑Centric Networking (CCN), Information‑Centric Networking (ICN), Mobility‑First, Nebula, XIA, and Choice Net.

Driven by the new‑infrastructure wave, demand for network talent has surged; certified professionals are scarce and highly valued.

Future Network Architecture

The open architecture of the Internet continuously spawns innovative applications. Over the next 5‑10 years, the shift from consumer‑centric to industrial‑centric Internet, along with VR/AR, holographic media, and 6G‑enabled intelligent services, will demand networks that are smart, open, and capable of extending capabilities to both ends.

Key points of future network architecture are: (1) enhanced network capabilities (deterministic transport, intrinsic security); (2) extensibility of these capabilities to applications; (3) strengthened control plane, simplified forwarding plane, and convergence.

Three major development directions are identified:

Intelligent Network : Data‑center networks are moving toward simplification and AI‑driven routing, congestion control, fault prediction, and self‑driven operation.

Multi‑dimensional Interconnection : Integration of heterogeneous networks (air‑space‑ground), massive IoT, and vertical industry networks into a unified IP‑centric fabric.

Compute‑Network Convergence : Distributed computing across cloud‑edge‑end requires tight coupling of network transport and compute resources to optimize QoS, latency, and resource utilization.

Service‑Customizable Network (SCN) is proposed to dynamically configure network resources based on user requirements for bandwidth, security, and latency, analogous to differentiated transportation services.

Future Data‑Center Network Technologies

Recent years have seen rapid development of data‑center networking, focusing on high performance, programmability, virtualization, and intelligence. Key emerging technologies include:

Large‑Scale L2 (Layer‑2) Technologies : TRILL, OTV, LISP, PBB‑EVPN, FabricPath, QFabric, CloudFabric, etc.

VXLAN : A virtual overlay network originally proposed by VMware and Cisco, now widely deployed.

Virtual Switching : Enables multiple switching functions on a single physical device or across devices, with VN‑Link drafts from Cisco and VMware.

Large‑Scale Switching : Vendor solutions such as Cisco VSS/VDC, Huawei CSS, ZTE VSC, H3C IRF, providing device virtualization and high‑density switching.

These technologies improve network resource utilization, security isolation, and flexibility, becoming standard in modern data‑center deployments.

Conclusion

With the widespread adoption of ABCDE technologies (AI, Blockchain, Cloud Computing, Distributed Computing, Edge Computing) and the arrival of the metaverse era, these emerging network and data‑center innovations will become integral to everyday life, offering opportunities for professionals interested in frontier industries.
