Frame Relay - Congestion control

1 Committed Information Rate (CIR). The average rate (in bit/s) at which the network guarantees to transfer

information units over a measurement interval T. This T

interval is defined as: T = Bc/CIR.

Frame Relay - Committed information rate (CIR)

1 Frame Relay connections are often given a committed information rate (CIR) and an allowance of burstable bandwidth known as the extended

information rate (EIR)

Network Neutrality - Pricing models

1 However, purchasers of connectivity on the basis of Committed

Information Rate or guaranteed bandwidth capacity must expect the capacity they purchase in order to

meet their communications requirements.

IEEE 802.17

1 Class A (or High) traffic is a pure committed information rate (CIR) and

is designed to support applications requiring low latency and jitter, such

as voice and video

Committed Information Rate

1 'Committed information rate' or 'CIR' in a Frame relay network is the average

Bandwidth (computing)|bandwidth for a virtual circuit guaranteed by an Internet

service provider|ISP to work under normal conditions. At any given time, the

bandwidth 'should not' fall below this committed figure. The bandwidth is

usually expressed in kilobits per second (kbit/s).

Peak information rate

1 'Peak information rate' ('PIR') is a burstable billing|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.

Traffic contract - Non-Real-Time Variable Bit Rate (nrt-VBR)

1 An application that might require an nrt-VBR service category is Frame

Relay interworking, where the Frame Relay CIR (Committed Information Rate) is mapped to a bandwidth guarantee in the ATM network

Burstable billing

1 'Burstable billing' is a method of measuring bandwidth (computing)|

bandwidth based on peak use. It also allows usage to exceed a specified threshold for brief periods of time without the financial penalty of purchasing a higher Committed

Information Rate (CIR, or commitment) from an Internet

service provider (ISP).https://store.theartofservice.com/the-committed-information-rate-toolkit.html

Burstable billing - 95th percentile

1 This method of billing is commonly used in peering arrangements

between corporate networks, it is not often used by ISPs because Internet Service Providers need Committed

Information Rates (CIRs) for planning purposes.

Traffic policing - Process

1 RFC 2697 proposes a more precise classification, with three colors.

[http://tools.ietf.org/html/rfc2697 IETF RFC 2697] A Single Rate Three Color Marker In this document, the contract is described through three

parameters: 'Committed Information Rate' (CIR), 'Committed Burst Size' (CBS), and 'Excess Burst Size' (EBS)
