IP camera design, LAN network consumption


We plan to deploy 100 COHU UNICAST IP cameras in our campus. Our network topology consists of one 6509 with sup2, CatOS, no SFM. This core connects to 16 IDFs via Fiber where 2950 edge switches are located.

I have got a 3 cameras to test the load, and found out that each camera would be transmitting approximately 250kbps on the switch port to the viewer station.

According to the suggested design some IDFs will have 25 IP cameras conneted to the switch which means almost 7MB traffic added to the existing traffic on the fiber uplink (approx 2MB)

Is there any problem or load on the core switch that these cameras might cause (current load approx 3% on msfc) especially if the cameras are grouped into several vlans, while the viewer stations in another vlan.

Is there any design guidlines or best practises for such a senario, and how can we really estimate the actual load when 100 cameras are in place.

All help is appreciated.
