Reference Traffic for Network Resource Dimensioning in FMC Environment

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.
