Fuzzy flow detection for IP cut-through

Several solutions, such as multiprotocol over ATM (MPOA) and IP switch router, are given for IP flow transport in ATM networks. Flow detection is necessary in all solutions above to decide when to cut through IP flow. We propose a fuzzy flow detector to give the IP cut-through decision. It shows how to design the detector and how the detector gives the IP cut-through decision. In the fuzzy flow detector system, three input variables are used, i.e., the arrived flow IP packets from the same source, the average interval time between adjacent packets, and the free capacity on the outgoing links to the destination. The output variable is the decision (cut-through or not). Moreover, the hardware implementation is also given.
