In a frame cloud it relates to the QOS levels your bandwidth contract has it's know as BIR (Burst Information Rate and CIR Committed Information Rate My understanding in simple terms is CIR means a guarenteed availablitity of say 128K burstable to say 1.5 meg on a T1 But the higher the CIR the more you pay Whichs means you get 128 k all the time and subject to availability 1.5 meg ie in the middle of the night Heh Cisco call it this too CIR committed information rate. Rate at which a Frame Relay network agrees to transfer information under normal conditions, averaged over a minimum increment of time. CIR, measured in bits per second, is one of the key negotiated tariff metrics. Bc Committed Burst. Negotiated tariff metric in Frame Relay internetworks. The maximum amount of data (in bits) that a Frame Relay internetwork is committed to accept and transmit at the CIR Be excess burst. Negotiated tariff metric in Frame Relay internetworks. The number of bits that a Frame Relay internetwork will attempt to transmit after Bc is accommodated. Be data is, in general, delivered with a lower probability than Bc data because Be data can be marked as DE by the network.
