Peak Information Rate

Peak Information Rate

The Peak Information Rate is a Burstable Rate Set on Routers and/or Switches that allow Throughput Overhead. Related to Committed Information Rate which is a Committed Rate Speed Guaranteed/Capped. Ex: CIR of 10 Mbit/s PIR of 12 Mbit/s. Allowing you access to 10mb of speed with Burst/Spike control that allows a throttle of an additional 2mb. (This allows for Data Transmission to "Settle" into a flow.
