Network Infrastructure

SD-WAN routes traffic intelligently across broadband, LTE, and private connections based on application requirements and real-time path quality. SASE converges SD-WAN, firewall-as-a-service, cloud access security broker (CASB), and zero-trust network access into a unified cloud-delivered platform. AIOps uses machine learning to predict network performance issues, detect anomalies, and automate remediation before users experience degradation. Wi-Fi 7 (802.11be) provides multi-link operation, 4096-QAM modulation, and 320 MHz channels for dramatically increased throughput and reduced latency. Intent-based networking translates business policies into automated network configuration.

SD-WAN connects branch offices to cloud applications with application-aware routing and automatic failover. SASE provides secure access for remote workers connecting to corporate resources from any location. AIOps platforms predict switch failures, detect unusual traffic patterns, and automatically reroute traffic before users notice disruption. Wi-Fi 7 access points serve high-density environments (stadiums, campuses, hospitals) with multi-link operation and dramatically increased capacity. Data center fabrics provide the ultra-low-latency, high-bandwidth interconnect that AI training clusters require.

SD-WAN reached approximately $8 billion in 2025 growing to $22 billion by 2030 at 22% CAGR. SASE reached $16 billion growing at 24% CAGR to $134 billion by 2035. Network-as-a-Service reached $21-33 billion growing to $269 billion by 2035. Wi-Fi 7 reached $6.5 billion growing to $36 billion by 2031. Data center Ethernet switch market grew 62% year-over-year in Q3 2025. The combined network infrastructure market spans hundreds of billions across equipment, software, and services.
