A "Burst Ratio" is defined for use as a measure of the burstiness of a packe t- based network. One illustrative implementation of the Burst Ratio (R) is whe re R is equal to the ratio of the average length of observed bursts in a packet arrival sequence over the average length of bursts expected for a random loss packet-based network. Another illustrative implementation of the Burst Ratio (R) is in the context of a 2-state Markov model, wherein R = 1/(1 + .alpha. - .beta.), and .alpha. is the probability of losing packet n if packet n-1 was found (i.e., the probability of being the next packet if t he current packet was received) and .beta. represents the probability of losing packet n if packet n-1 was lost (i.e., the probability of losing the next packet if the current packet was lost).
