Reference Traffic for Network Resource Dimensioning in FMC Environment

Abstract

Unassumed teletraffic patterns, such as those caused by extra-high bit-rate mobile user traffic that actively moves in a network, will be become common in telecommunication networks in the 4th generation (4G) era. The unexpectedness and unevenness of their distribution will make it difficult to use ”fundamental traffic, ” which is the conventional concept of???reference traffic, especially in Japan, based on the E.500 ITU-T???standardization series for network resource dimensioning. New radio access technologies are being intensively developed toward 4G, but the argument for traffic engineering is still insufficient. We propose a new model and new metric of reference traffic for handling such cases. The metric is called ”redundancy under general traffic in a closed network.” We also developed a calculation method approximated using a normal distribution. We discuss the evaluation of this method using Monte Carlo simulations, and show examples of reference traffic by using this method in real operations of next-generation telecommunication carriers toward the fixed and mobile convergence (FMC) network.
