EVALUATION OF THE USE OF THE NATIONAL ACADEMIC NETWORK OF ADVANCED TECHNOLOGY (RENATA) IN COLOMBIA EVALUACIÓN DEL USO DE LA RED ACADÉMICA NACIONAL DE TECNOLOGÍA AVANZADA (RENATA) EN COLOMBIA

This paper models the operation of Internet 2, the advanced national academic network (RENATA) in Colombia, by as-sessing the fundamental services that it supports and its respective performance. The academic and scientific importance of the article lies on discussing the problem of NRAN networks not being harnessed as scientific tools that may have a domino effect by driving the use of said tools in different education and research centers of the highest level. It is concluded that the connectivity model 1 Facultad de Ingeniería. Universidad Nacional de Colombia. Bogotá, Colombia.

In emerging countries, [3] a production function specified concluded that an increase of 1% in broadband penetration contributes 0.0158% to GDP.

Impact on job creation:
The impact of increased penetration of broadband versus job creation, are broken into two types of effects: jobs arising from the deployment of infrastructure and the resulting employment network effects and spill into other areas of the economy [4].
There are six studies that estimate the impact of the construction of broadband networks in employment: [5], [6], [7], [8], [9] Y [10]. These estimate the number of jobs created as a result of capital investment required for the deployment of broadband networks and conclude that there is a positive effect where increased penetration of 1% in broadband contributes to employment growth 0.002% to 0.3%. Figure. 3. Creation employment for broadband penetration. [4].

Impact on the increase in average household income:
A study in the city of Costa Rica, [eleven] Concluded that an increase of 1 percentage point in the regional broadband penetration results in an increase of 2.96% in the average household income.
Katz (2010d) A study the state of Kentucky in the United States [12], It was determined that, on average, an increase in broadband penetration of 1% results in an increase of 0.097% in the average household income in the following year.

Impact on creating consumer surplus:
This concept is defined as the benefit of users to be able to acquire a service for a lower price than they would be willing to pay.
In an analysis conducted between the period 1999 to 2006 in the United States [13], It was determined that the surplus generated by broadband represents 7.5 million US dollars, equivalent to 27% of the total surplus of the country.

RENATA network topology
Renata is made up of three government agencies: Ministry of ICT, Ministry of Education and Colciencias and eight regional academic .   Datacenter Enterprise was used. In the No 9 Renata illustration topology simulated under free software GNS3 shown with a test LAN to LAN connectivity between the "Universidad del Rosario" and "Universidad de Antioquia".  To provide connectivity to customers of regional   it is SNCTI, they add points for the accreditation process in the academic program.
As an example, in this research, the University of the Andes to evaluate your use of Renata

IMPLICATIONS
The academic importance of this work involves using powerful simulation tools such as gns-3 in the assessment and efficiency of high-speed academic networks in scientific research since implementation and operation in real time is very expensive in networks such as RENATA.
It allows to know firsthand the speeds, operativity, function and behavior in real time of these academic-oriented networks. On another note, the article presents an assessment and future outlook in the use and potential of high-speed academic networks in Colombia.

CONCLUSIONS
