Large-Scale Intelligent Building Multi-Subsystem Converged Networking Solution

Large intelligent buildings have many subsystems, scattered points, and high reliability requirements. The solution adopts a dual-core, dual-egress, zone-based aggregation architecture. Office, security, building automation, wireless, and IoT are connected to different aggregation and VLANs, with logical isolation and no mutual interference. Dual cores provide redundancy through stacking/VRRP, so a single device failure does not affect services. IBMS, NVR, access control platform, BA, and energy management platform are centrally connected to the core to achieve data interoperability and linkage. QoS ensures priority transmission for video, control commands, and critical services.
