Figure 50: Deployment scenario — bridged video surveillance and IP camera deployment for
transportation, airports, and government
The following list outlines the benefits of the bridged video surveillance solution:
• Easy end-point provisioning
• sub second resiliency and mc forwarding
• secure tenant separation
• quick camera switching
Video surveillance — routed
In a video surveillance solution, optimal traffic forwarding is a key requirement to ensure proper
operation of the camera and recorder solutions. However, signaling is also important to ensure quick
channel switching. This is achieved by deploying an IP multicast infrastructure that is optimized for
multicast transport, so that the cameras can be selected quickly, and so that there is no
unnecessary traffic sent across the backbone. In the topology shown in the following figure, each
camera is attached to its own IP subnet. In a larger topology, this can reduce network overhead. To
increase network scalability, you can attach a set of cameras to a Layer 2 switch that has IGMP,
and then connect the cameras to the fabric edge (BEB) which has a routing instance.
In many customer scenarios, surveillance must be separated from the rest of the infrastructure. This
can be achieved by deploying a Layer 3 VSN for the surveillance traffic to keep the surveillance
traffic isolated from any other tenant.
Fabric connect enables this solution with support for ERS 8000, VSP 7000, VSP 9000 and VSP
4000 products.
