Committed Information Rate - you can buy virtual circuits with a guaranteed CIR Your provider guarantees that this rate will be available as needed Common CIRs include: 32 Kbps, 64 Kbps, 128 kbps, and 256 Kbps If you transmit over this speed, you're in danger of losing packets and data If the carrier's service is not working well, it may show congestion and packet loss, even if you are under your CIR
Committed Information Rate: CIR is the information transfer rate which a network offering Frame Relay Services (FRS) is committed to transfer under normal conditions The rate is averaged over a minimum increment of time
Committed Information Rate The bandwidth that is statistically guaranteed to a frame relay customer While it is often possible to "burst" transmission rates higher than one's CIR, the frame network does not guarantee that data in excess of the CIR will be routed through the network
Central Identities Register The CIR will provide a unique ID for every "person" associated with UCT This will include students, staff, alumni, customers, vendors, funders, etc
Committed Information Rate - The bandwidth (measured in bits per second) guaranteed by the DirecPC system to a service provider It's possible that additional traffic may also be delivered, but it's not guaranteed
(Committed Information Rate) The speed at which a Frame Relay network agrees to transfer information under the normal line conditions, averaged over a minimum time increment
Committed Information Rate The maximum data rate that a Frame Relay network provider guarantees to transfer under normal network conditions, averaged over a minimum increment of time CIR is either equal to or less than the full port speed Measured in bits per second, CIR one of the key negotiated cost factors in setting up a Frame Relay connection Also see EIR
Committed Information Rate The rate, measured in bits per second and averaged over a set time interval, at which a Frame Relay network provider contracts to transfer information across the network under normal conditions
Committed Information Rate In Frame Relay and wireless data networks, where bandwidth is shared dynamically between subscribers, CIR is the minimum amount of bandwidth that the carrier is obligated to provide to the subscriber at all times
Committed Information Rate The minimum bandwidth guaranteed by the frame relay services operator Example: it is possible to ask the operator for a connection between 2 sites with a CIR of 64 kb/s, whilst at the same time benefiting from a superior bandwidth when the network is only being used lightly Billing for the link is always based on the CIR
