Increased convergence of fixed and mobile networks necessitates a combined network modelling approach to identify optimum locations for core network functions and potentially leverage synergies. The fixed-mobile convergence (FMC) traffic modeling approach documented in this paper is based on the CISCO Visual Networking Index and focuses on the network of a big German incumbent. As a first step, fixed traffic is distributed across Germany according to the number of potential xDSL customers, while mobile network traffic is dispersed with the help of mobile traffic measurements. Emerging traffic is then assigned to more than 7000 access areas, aggregated via a metro network with more than 800 regio points of presence (PoPs) and directed towards the backbone network with 18 core PoPs. Under these assumptions, the busiest regio PoP will experience traffic of 15.2Gb/s in the year 2017, with 14.4Gb/s accounting for fixed network traffic and only 0.7Gb/s for mobile network traffic. The busiest core PoP will have to deal with a throughput of 390Gb/s, with 370Gb/s originating in the fixed network and 20Gb/s in the mobile network.
