For those charged with the design and implementation of enterprise IT networks, a vexing problem is that technology advances at uneven rates across the hardware ecosystem. When we hit a new tier of speed, first out of the gate usually come (very expensive) modules for high-end core switches and routers. Faster interfaces gradually trickle down to edge switches and server interface cards, and only later do affordable options come to network monitoring and security appliances.
We're at the midpoint of this process with 10-Gbps Ethernet; switch ports are available for less than $200, and server adapters are in the same range for older systems that don't already have multiple 10-Gbps ports embedded on the motherboard. But start pricing equipment to monitor and secure 10-Gbps Ethernet networks, and you'll be in for sticker shock. And forget about your 40- or 100-Gbps gear.
