چکیده انگلیسی
The rapid growth in the number of Internet users has accelerated the use of high-speed Internet access services, including broadband multimedia services. In the delivery of broadband multimedia services to end-users, it is necessary to build a high-speed backbone and access network. To construct a broadband access network, several alternative technologies including xDSL, CATV, and FTTx have been suggested and implemented in telecommunication networks. However, even if a technology is proven to be optimal for the current environment, it can be deteriorated by the elapse of time or the advent of new challenging technologies in the future. In this article, we concentrate on the selection of an evolution path for broadband access networks. We developed an optimization model for selecting the best technology and evolution path with the minimum total cost. The problem can be formulated as a mixed integer programming model. With a scenario for demands and cost factors, we find the optimal evolution path by solving our model with the CPLEX program and illustrate some sample paths for the broadband access network evolution plan. Once the cost and the demand are defined in detail to reflect the real-world case, our model can be useful to generate a practical technology evolution plan for broadband access networks in real-world applications.
