The scenario
Tokyo Metro operates many IP cameras across stations and requires uninterrupted video recording and monitoring. The design connects station PoE switches to a redundant 10G core ring for failover and centralized video management.
What is in this drawing
Read the decisions behind it.
01
Use a three-node 10G fiber ring between core L3 switches for path redundancy
02
Attach station PoE switches to separate core nodes for access diversity
03
Centralize VMS and storage at core while keeping NVR and monitoring workstation in the control room
Large-scale IP CCTV deployments needing high availability, distributed camera aggregation, and centralized management across multiple sites.
