IDC의 세계 엔터프라이즈 네트워크 인프라 분류(2026년)

This IDC study provides a detailed description of IDC's enterprise network infrastructure (ENI) taxonomy. It serves as the foundation for classification, segmentation, and sizing of the worldwide enterprise network infrastructure and services market. The taxonomy encompasses the products, technologies, and services used to build, operate, and support enterprise and service provider networks across key domains, including datacenter, campus, branch, edge, and cloud environments.The ENI taxonomy organizes the market into four primary segments - network hardware/equipment, network software, network cloud services, and network life-cycle services - each further divided into secondary markets covering key technologies such as switching, routing and SD-WAN, WLAN, network management software, network cloud services, and network life-cycle services. This structure provides a comprehensive framework for analyzing how networks are designed, deployed, managed, and consumed, while underpinning IDC's network infrastructure research and data products and enabling consistent market definitions, vendor performance analysis, and tracking of technology adoption and global market trends."IDC's enterprise network infrastructure taxonomy provides a comprehensive framework for understanding how modern networks are evolving across on-premises, cloud, and hybrid environments. As enterprises increasingly prioritize automation, security, and cloud-driven architectures, this taxonomy serves as the foundation for tracking market transformation and vendor innovation across the networking ecosystem," states Brandon Butler, senior research manager, Network Infrastructure and Services at IDC.
