Resumen:
This project, at its initial stage, carries out a study and an analysis of the access
networks of fixed-telephony operators in Colombia in order to give a further
diagnosis of their network state and also implement a general access network
model that gathers the common characteristics of operators. Afterward, a general
description will be done about architecture, features, advantages, disadvantages
and access network services NGN. Later on, a migration model is presented for the
access network proposed by the ITU and some migration criteria are determined.
These criteria will be used as a reference to the operators in their evolving process
toward NGN. At last, a transition process is performed for the general model of
access network using the solution of a technological provider and a service model is
also performed according to the characteristics of the next generation networks.
