This paper presents an investigation into the quality of
service (QoS) of cybercafés networks in Nigeria using five
different cybercafés in Akure metropolis as a case study. The
study was carried out in three stages. In the first stage,
Distributed Internet Traffic Generator (D-ITG V. 2.4) was used
to measure the QoS metrics such as packet loss, average jitter,
bandwidth and delay standard deviation on the five cybercafés
networks investigated. The second stage, involves the
administering of questionnaires to users of studied cybercafés in
order to obtain primary data on some of the users’ QoS metrics
such as reliability and efficiency of the networks. The final stage
involves visitation to the cybercafés considered to obtain onsite
data on specifications of computers using for browsing in the
cybercafés. The result of the study shows that all the networks
considered were inefficiency, congested and unprotected. It was
also found from the study that, there is direct correlation
between the bandwidth, number of terminals and the efficiency
of the network. The paper was concluded with suggestions on
how to improve the QoS of internet cybercafés in Nigeria in
order to enhance teaching and research through internet facility
in the country.
