Figure 49: 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 an L2
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 an L3 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.
