Service providers world-wide are facing challenges of network operations, management, security, quality of service and address deficiency problem while the current world network still run with the existing legacy system. The issues of address shortage including the problems of legacy IPv4 address have been resolved with the advancement on IPv6 addresses. Similarly the increasing complexities of networking management have also been addressed by the advancement on Software Defined Network (SDN). For the future sustainability, service providers have to migrate their existing network to newer technologies. This requires upgrades on or replacement of existing networking devices that are operating on real time. But the lack of sufficient cost, technical human resources and suitable migration plan are becoming the major challenges for the fairly sustained service providers to migrate their existing network into next generation programmable network.SDN and IPv6 are the two new paradigms in networking operation and management that jointly after migration addresses all the existing issues of current networking system. In this paper, we present a greedy algorithm to identify the migration cost of network devices in the optimal path based on customer demand for incremental adoption of SDN enabled IPv6 network. We justify that a unified migration approach to SDN and IPv6 network would help to reduce the total cost of migration. We also verify that sequence of migration considering customer demand and cost constraints give the good estimation for unified migration to Software Defined IPv6 (SoDIP6) network.
Recent advancement in the field of Information and Communication Technology (ICT) has encouraged all stakeholders to move towards the new networking paradigm. Internet Protocol version 6 (IPv6) addressing, Software Defined Network (SDN) and Network Function Virtualization (NFV) are regarded as technologies for enhancing network efficiency and effectiveness. However, the technology migration becomes one of the central challenges for the stakeholders such as service providers, end users, and regulatory bodies. This is more challenging in case of developing countries due to lack of sufficient cost and skilled human resources. In this paper, we provide an overview and survey of SDN and IPv6 networking technologies, their benefits and future challenges. Then we introduce Software Defined IPv6 (SoDIP6) network as a next generation networking technologies and their unified approach of deployment over the Tier-3 ISPs of the developing nations that could help for speedy and smooth migration with optimized cost. The demonstrated superior features of SDN enabled IPv6 network from different perspectives with its contributions to green ICT are recognized as the networks of the future generation in the networking world.
Summary With the increasing number of Internet of Things (IoT) devices, current networking world is suffering in terms of management and operations with lack of IPv4 addresses leading to issues like network address translation (NAT) proliferation, security and quality of services. Software‐defined networking (SDN) and Internet Protocol version 6 (IPv6) are the new networking paradigms evolved to address related issues of legacy IPv4 networking. To adapt with global competitive environment and avoid all existing issues in legacy networking system, network service providers have to migrate their networks into IPv6 and SDN‐enabled networks. But immediate transformations of existing network are not viable due to several factors like higher cost of migration, lack of technical human resources, lack of standards and protocols during transitions, and many more. In this paper, we present the migration analysis for proper decision making of network transition in terms of customer demand, traffic engineering, and organizational strength with operation expenditure for network migration using evolutionary gaming approach. Joint migration to SDN‐enabled IPv6 network from game theoretic perspective is modeled and is validated using numerical results obtained from simulations. Our empirical analysis shows the evolutionary process of network migration while different internal and external factors in the organization affect the overall migration. Evolutionary game in migration planning is supportive in decision making for service providers to develop suitable strategy for their network migration. The proposed approach for migration decision making is mostly applicable to fairly sustained service providers who lack economics, regulation/policy, and resources strengths.
