Modeling and simulation of data transmission on a hybrid fiber coax Cable network
Simulation Modelling Practice and Theory, 2004Co-Authors: Manuel García, Daniel F. Garcia, Víctor G. García, Riccardo De BonisAbstract:Abstract This paper describes the steps followed in the development, simulation, and later validation of a model for a Cable network based on hybrid fiber-coax (HFC) technology, used for data transmission. This work presents a representation of a communication system which has been growing dramatically over recent years and will continue to do so in the near future. The modeling process is based on the analysis of measurements of a Cable Operator, establishing a direct relationship between model parameters and network characteristics. The modeling technique produces a scalable model capable of simulating the evolution of the real Cable network.

Analysis and modeling of traffic on a hybrid fiber-coax network
IEEE Journal on Selected Areas in Communications, 2004Co-Authors: M Garcia, V. G. Garcia, D. F. Garcia, Riccardo De BonisAbstract:This paper presents the study carried out on the data traffic collected on the network of a Cable Operator based on hybrid fiber-coax technology, and the subsequent simulation model developed to predict the bandwidth requirements of the network channels. The paper starts with the analysis of the traffic measurements, taken over two periods of time in one year, on all the network's channels. This analysis identifies the main characteristics of the traffic, as well as some relationships between network parameters and their persistence over time. The paper proceeds to present the development of a simulation model, which represents the Cable network. This model is built from the results of the traffic analysis and network parameters. The major challenge of this model is to predict the traffic on each channel of the Cable network, related to parameters of the network configuration, such as the number of assigned subscribers to the channel and the time of day. To reach this goal, the simulation model has been developed with a modular structure, which gives it flexibility to adapt to changes in the network. The process followed involves the establishment of a traffic model, a system model, and finally, the validation of the results.

HSNMC - Traffic Model Characterization of an HFC Network
Lecture Notes in Computer Science, 2003Co-Authors: Manuel García, Daniel F. Garcia, Víctor G. García, Riccardo De BonisAbstract:This paper describes the traffic model developed to represent the traffic observed on the telecommunication network of a Cable Operator providing data services. The Operator network is based on a hybrid fiber coax (HFC) network using ATM technology. The traffic model is based on the measurements taken on the upstream channels of the network and represents the behavior of the subscribers by simulation.

pno and Cable Operator broadband upgrades
1998Co-Authors: B T Olsen, Kjell Stordahl, D Myhre, Alcibiade ZaganiarisAbstract:This chapter presents a techno-economic analysis of broadband access network upgrade strategies for public network Operators and Cable Operators in a competitive environment in the residential and small business market. The study focuses on network evolutionary paths from the existing network towards a target broadband architecture. The intermediate steps and final network solutions include the technology options of broadband twisted pair modems, hybrid fibre coax networks and asynchronous transfer mode (ATM) based passive optical networks (PONs) [1].

Techno-economic evaluation of narrowband and broadband access network alternatives and evolution scenario assessment
IEEE Journal on Selected Areas in Communications, 1996Co-Authors: B T Olsen, D Myhre, A. Zaganiaris, K. Stordahl, T. Overli, M. Tahkokorpi, I. Welling, M. Drieskens, J. Kraushaar, J. MononenAbstract:The paper presents the main results obtained within the Research in Advanced Communications in Europe (RACE) project: 2087 TITAN regarding minimum-risk introductory routes for new narrowband and broadband services in the residential and small business market. The project developed a methodology and a tool for techno-economic evaluation of advanced narrowband and broadband telecommunications networks and services. Results from four extensive access network studies are presented. For the narrowband services, optical access and radio in the local loop have been assessed and compared to conventional copper layout in a greenfield environment. Access network upgrade strategies for emerging new broadband services have been evaluated in three studies, with technological options ranging from enhanced copper to hybrid-fiber-coax (HFC) and broadband passive optical networks. An extensive study on different broadband access network upgrade alternatives for public network Operators (PNOs) were carried out, taking into account the diversity of conditions met today by European countries. In another study, the effect of competition In the access network was modeled assuming two main Operators sharing the market. Broadband upgrade alternatives were evaluated for a new Cable Operator, competing with the dominant public network Operator. In addition, video-on-demand (VoD) and Internet access upgrades have been analyzed. The paper demonstrates the viability of techno-economic studies for the access network, including in-depth analysis of the time-dependence of component cost, tariffs, service penetrations and market shares.
