It is the burst measurement that is used to determine the DE status of the packet, or for the ATM traffic policy, it is the burst measurement used to determine the conformance of the packets. Thus, a determination is made whether the packets should be immediately dropped because they exceed their traffic contract. There are three burst measurement options implemented for modeling the traffic policing. The three measurements are Sliding Window, Jumping Window, and Leaky Bucket. The burst algorithms are set in the transport protocol under traffic policing. The Sliding Window algorithm measures the burst as the total size of the packets that arrived during a fixed interval before the current time. This interval slides according to the time, and the measurement always includes all the packets that have arrived for the previous full interval. The Jumping Window algorithm measures the burst based on accumulating a burst size with each packet, but then clearing that accumulation at fixed intervals. The Leaky Bucket algorithm (or the Generalized Cell Rate Algorithm, GCRA for ATM) is similar to the jumping window algorithm in terms of allowing excess traffic, except that it periodically subtracts off an amount equal to the rate times the burst interval. This maintains some memory of the previous burst interval, especially if that burst exceeded the value of the burst rate times the burst interval. Burst Units The type of units set for the burst size under the traffic policing option of the transport protocol. Traffic Type One of the following: FRLB = Frame Relay Leaky Bucket FRSW = Frame Relay Sliding Window FRJW = Frame Relay Jumping Window ATM None 140
