Critic Sistematization Of Standardization Tendencies Of The Architectures And Protocols In Optical N
(Eduardo José Aloia)
Critic sistematization of standardization tendencies of the architectures and protocols in optical networksThe main objective of this work is to analyze the evolution trends forthe architecture of the optical networks, discuss the state of the artprotocols required for its development and evaluate the various effortsbeing carried out by different institutions in order to achievestandardization. In this context, optical networks are those in whichthe dominant technology in the physical layer is the optical fiber.Such networks arose in the early eighties with the use of the monomodofiber optic cables and were further developed with the introduction ofa new technological base composed by new types optical fibers, opticalamplifiers, DWDM systems and optical components such as add/dropmultiplexers and optical cross-connects. The introduction of thesecomponents will make possible the evolution from the simplepoint-to-point DWDM connections to the all optical networks. In thiswork we analyze how the applications will interact with this physicallayer. Such interaction has been proving to be a challenge within theframework for the current architecture of data networks, aiming atoffering solutions to enable the transport of a great volume of trafficin an efficient manner. With this goal in mind, the use of technologiessuch as MPLS (Multiprotocol Label Switching) and its evolution, theGeneralized MPLS (GMPLS) is discussed. Finally, we present the ITUversion for the architecture optical networks, addressing its mergingwith the GMPLS
