Peak information rate
Peak information rate is a burstable rate set on routers and/or switches that allows throughput overhead. Related to committed information rate which is a committed rate speed guaranteed/capped. For example, a CIR of 10 Mbit/s PIR of 12 Mbit/s allows you access to 10 Mbit/s minimum speed with burst/spike control that allows a throttle of an additional 2 Mbit/s; this allows for data transmission to "settle" into a flow. PIR is defined in MEF Standard 10.4 Subscriber Ethernet Service Attributes
Excess information rate is the magnitude of the burst above the CIR.
Maximum information rate in reference to broadband wireless refers to maximum bandwidth the subscriber unit will be delivered from the wireless access point in kbit/s.
