CIR is the Committed Information Rate which is determined by the Frame Relay vendor. It is the rate they guarantee that they will move your data through their Frame Relay network. Each PVC (DLCI to DLCI connection) can have a different CIR. >From your example (I'm assuming that you are giving Port Access speeds) it appears that there is a central router with a 128k Port Access and 2 branch routers with 64k Port Access. The Port Access is the bandwidth/speed that the router connects to the Frame Relay network. Data can possibly be moved at Port Access speed through bursting above the CIR even though the Frame Relay provider only guarantees the CIR. >From the information you gave the CIR isn't known; however, neither PVC can move data beyond their Port Access speed which in your example is 64k.
