Prevent an Encryption Bottleneck on High-Speed Links

September 7, 2017

What if you had a car with a powerful, turbo-charged engine that could fly along at 130 mph —until you turned on the air conditioner and watched the max speed drop to 50? Pick up two friends, and it struggles to maintain 30 mph.

This would be depressing for you as a driver, but it does make a good analogy for IT managers trying to leverage Internet Protocol Security (IPSec) for high speed link encryption requirements. In this approach, the routers’ throughput capabilities are restricted to the IPSec encryption engine limits, rather than using an encryption solution that can leverage the maximum aggregate throughput capabilities of the router.
