    The paper proposes a novel optimized model for transition from IPv4 to IPv6 networks. The aim of this paper is to design the Original IPv6 Transition Controller Application and compare its performance with 6to4 tunneling using OPNET 17.5 with identical traffic and network loads. The analysis is based on an experimental design with simulation for better, faster and a more optimized solution through empirical measure of the process. The OPNET Modeler simulator was used to accurately model and predict the behavior of the real world system. The purpose of such detailed modelling efforts and analysis was evaluated using distinct performance metrics: data access (measured through response times of database queries), video conferencing (measured through video packet delay variations and end-to-end packet delays), and IP telephony voice communications (measured through jitters, mean opinion score, packet delay variations, and end-to-end packet delays). The paper presents the redesigned network model for ensuring that the IPv6 Transition Controller can control all the voice, video, and data sessions through “traffic recognition and routing” and also verifying the ToS status of the traffic and controlling the prioritization accordingly using IPv6 Transition App. The final results show that the model is optimized besides, focusing on traffic recognition, routing and prioritization, it ends up being the best design concept to achieve IPv6 deployment and high quality of service.

    The world has been beset with fears of future global overpopulation overwhelming the earth’s ecological system and producing shortages of energy, resources, water and food. The sustainability has been a major long-term concern, climate change is thought to be causing a warming of the planet, an increased incidence of extreme weather events, a reduction in agricultural yields, melting the ice caps, and rising sea levels which will eventually cause flooding of low lying islands and coastal districts. As a result, there is dire need for population checks in the world. The causes of overpopulation are attributed to cultural beliefs, lack of sex and population education, religious beliefs etc. The effects of overpopulation include mass poverty, increased death rate, unemployment, etc. It becomes eminent that some measures should be put in place to address this global issue. Some past measures included equipping and funding public and special libraries to disseminate population control in...

    This paper presents a performance evaluation study of dual stack, 6to4 tunnelling, and Network Address Translation transition schemes on simulative method in IPv4/IPv6 networks. This research aims to find out what IPv4/IPv6 transition scheme performs better in terms of performance parameters packet losses, delays, segment delays, query response times, packet delay variations, packet end-to-end delays, jitters, mean opinion score value, and traffic sent and received for data, voice and video traffic. An equal capacity of network load in terms of probes for the three scenarios is considered and benchmarked to ascertain the impact on the performance parameters on IPv4/IPv6 networks. The scenarios are basically network models configured and simulated using Optimized Network Engineering Tool modeler. The core model designed represents an Internet Service Provider network deployed to form an ideal choice of IP domain corresponded to a realistic network topology running both IPv4 and IPv6 ...

    Information Technology (IT) infrastructure and related research communities can help tackle environmental challenges in developing countries through environmentally sustainable models of economic development. The paper sought to examine the status of current and emerging environmentally friendly technologies, equipment and applications in supporting programs that play a role in addressing environment degradation in Kenya. It also sought to underscore the role of IT in environmentally sustainable consumption. The paper examines what constitutes environment degradation and explores the negative effects of IT infrastructure on the environment. The consequences of E-waste on environment are discussed followed by green IT as part of the solution to environment degradation as a result of adoption of IT. The papers also discuss the available IT infrastructure that can be used to combat the challenges of environment degradation. The paper ends with possible IT infrastructure measures that c...

    There are many emerging technologies in the 21st century as far as technology is concerned. These emerging ICTs provide the most profound impacts on information management and organizational growth. This paper is an attempt to generate research to create a comprehensive understanding its role and impact on organizations. The emerging technologies identified are those that have a high level of generality with a significant possibility of having an effect on the way humans interact with the world. This shall be achieved by identifying the state of the art emerging ICTs and establishing its impact on information management and organization growth. The desktop review shall be used on a global perspective.
