In frame relay networks, a committed information rate (CIR) is a bandwidth (expressed in bits per second) associated with a logical connection in a permanent virtual circuit (PVC). Frame relay networks are digital networks in which different logical connections share the same physical path and some logical connections are given higher bandwidths than others. Because the CIR is defined in software, the network's mix of traffic bandwidths can be redefined in a relatively short amount of time.
