Multi-Criteria Comparison Between Legacy and Next Generation Point of Presence Broadband Network Architectures

Development of new applications and the introduction of innovative technologies can lead to revise network architectures in order to build sustainable broadband infrastructures. Thepresent paper describes the main drivers and enabling technologies leading to change the current fixed and mobilenetwork architectures. The limitations of the aggregation network are briefly shown by a description of the legacy network architecture. The advantages of optical access technologies arealso depicted. In order to avoid certain bottlenecks in the aggregation segment, an advanced solution called NextGeneration Point of Presence (NG-PoP) is presented. The main idea of NG-PoP architecture is to move the existing boundariesbetween access and aggregation networks. Finally, the NG-PoP architecture is analyzed and compared to the legacy network oneaccording to several criteria such as Quality of Service (QoS),cost criteria, power savings and Fixed Mobile Convergence (FMC) features
