Proposta de migração do protocolo IPv4 para o protocolo IPv6 em redes de computadores em Moçambique

Abstract

Considering that several business areas such as industries, companies and academic institutions adopted services based on information technologies, but on the other hand, the current condition of the fundamental Internet protocol presents some obstacles to face the present condition of the global network, transition techniques from IPv4 protocol to IPv6 are researched, in order to propose a migration model from the IPv4 protocol to the IPv6 protocol in computer networks. To do so, it is necessary initially to present the network architecture based on the IPv4 protocol, identify the constraints of the IPv4 protocol and describe the characteristics of the operation of the IPv6 protocol. Therefore, the work is carried out based on a research of basic strategic purpose, descriptive objective, under the hypothetical-deductive method, with a qualitative approach with bibliographic and documentary procedures. In view of this, it appears that the transition techniques offer a means for the two protocols to interoperate for a good period of time until IPv6 is mostly implemented and finally IPv4 is replaced. It is also verified that the different migration techniques, in addition to offering support for the interoperability of protocols, can also work in the same network, offering diversified services for specific difficulties.
