Peak information rate

Peak information rate (PIR) is a burstable rate set on routers and/or switches that allows throughput overhead. Related to committed information rate (CIR) 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.[1][2] PIR is defined in MEF Standard 10.4 Subscriber Ethernet Service Attributes[3]
Excess information rate (EIR) is the magnitude of the burst above the CIR (PIR = EIR + CIR).[citation needed]
Maximum information rate (MIR) in reference to broadband wireless refers to maximum bandwidth the subscriber unit will be delivered from the wireless access point in kbit/s.[4]
