structure, which continued to be used for many years after NSFNet
It could be seen that different converters placements are obtained for K=3 and K=5 (in the case of NSFNet
) and for K=4 and K=10 (in the case of EON), compared to Scenario II.
Entre 1989 y 1994 America Latina ya estaba conectada por TCP/IP (Internet) con NSFNET
(National Science Foundation Network) (Dholakia, et al., 2003; Garay, 1999; Islas Carmona, 2011), mas este hecho no se puede confundir con una apropiacion tecnologica.
As TCP/IP was being developed and ARPANET and NSFNET
were growing, someone had to be managing the existing networks.
Finally in 1994 the centralized routing protocols or NSFNet
Internet Backbone was replaced by a Border Gateway Protocol (BGP) which allowed direct communications between computers without having to go through the central system.
then operated by the National Science Foundation (NSF) as NSFNET
It was later popularized by the United States National Science Foundation (NSFNET
), the first nationwide educational network linking universities and academic research establishments.
