As the title says, I have 200Mbps of streaming video traffic coming into my command center. How do I split the load between routers?

Setup is like this:

fiber ---> router ---> switch ---> workstations

I'm sorry I haven't dealt with this much traffic before. so please be gentle if you're going to kick me out :)

EDITED FOR DETAILS:

Okay, this specific project is for our company's IP CCTV system. We have deployed over 100++ cameras all over a building/campus and we have estimated each camera to take about 2Mbps of bandwidth each. Now, they're all connected to a switch and that's entirely fine. But coming into our command center, they have to be on a router since it'll get more than 200++ cameras next year (and I don't want to have too many hosts on one subnet). My plan was to have the 1st hundred on a 172.16.9.x block and the 2nd hundred on a 172.16.10.x block (all /24).

The servers I have are currently sized to match (about 5 dual 6-core xeons) and I'd have about 19 workstations all streaming video from the 5 servers. (servers pull video from the cameras).

But 200Mbps of constant traffic? How the hell do I even break this up? I need to have 1 gateway, to manage the routes...

I honestly think I'm way in over my head.
