Classification: H04L

Abstract:
A system for determining a committed information rate (CIR) for a frame relay data communications device to facilitate the conversion of frame relay data packets into asynchronous transfer mode (ATM) data cells, comprising:a processor coupled to a local interface; a memory coupled to the local interface; an adaptive CIR logic stored in the memory, the adaptive CIR logic being executed by the processor, the adaptive CIR logic including: sample identification logic to identify at least one sample group of a number of data packets transmitted across a data communications link, the data packets having a variable length and the data cells having a fixed length; and modeling logic to adapt a modeled packet size of the frame relay data packets transmitted across the data communications link based upon the data packets in the sample group; and modeling logic to calculate an efficient committed information rate based upon the modeled packet size.
