- A study on the multiple dynamic wavelength distribution for gigabit capable passive optical networks Gustavo Adolfo Puerto Leguizamón Jaime Andrés Vallejo Avellaneda Jhon Jaime Ramírez Ochoa Ingeniería Gigabit Pon Service Distribution Optical Access Networks Passive Optical Networks Dynamic Wavelength Allocation This paper presents a data traffic based study aiming at evaluating the impact of dynamic wavelength allocation on a Gigabit capable Passive Optical Network (GPON). In Passive Optical Networks (PON), an Optical Line Terminal (OLT) feeds different PONs in such a way that a given wavelength channel is evenly distributed between the Optical Network Units (ONU) at each PON. However, PONs do not specify any kind of dynamic behavior on the way the wavelengths are allocated in the network, a completely static distribution is implemented instead. In this paper we evaluate the network performance in terms of packet losses and throughput for a number of ONUs being out-of-profile while featuring a given percentage of traffic in excess for a fixed wavelength distribution and for multiple dynamic wavelength allocation. Results show that for a multichannel operation with four wavelengths, the network throughput increases up to a rough value of 19% while the packet losses drop from 22% to 1.8% as compared with a static wavelength distribution. 2014 artículo científico 0123-921X https://www.redalyc.org/articulo.oa?id=257030546002 en http://www.redalyc.org/revista.oa?id=2570 Tecnura application/pdf Universidad Distrital Francisco José de Caldas Tecnura (Colombia) Num.40 Vol.18
