The Accuracy of the Equivalent Random Method With Renewal Inputs*

The equivalent random method1(aso see Ref. 2) is widely used to approximate the blocking probabiUties for non-Poisson traffic streams. Although much numerical experience and some analjrsis (e.g., Ref. 3) suggests that the method is usually reliable for superpositions of overflows, the reason for its accuracy (or errors) deserves further attention.
