The evolution of the Next Generation Networks have recently received attention by researchers in the academic community and followed –up with various proposed models on this hot topic- “Software Defined Networks”. Software Defined Networking supported the centralization of the routing control logic of the management plane for intelligent networks. In this paper, we present a holistic view of the various challenges that comes with the framework and standardization activities while focusing on the technical perspectives rather than the financial and political view of intelligent traffic handling bearing in mind the network loads and other performance metrics. The Hybrid Software Defined Networks (SDN) explores a new direction to this research in Inter-Domain Routing Network Application with the introduction of SDNi main idea and exchanged states. This gives us insight over multiple transports network protocols that controls the internetwork. We analyse the associated trade-offs beginning from the promises of Software Defined Network Interconnection {SDNi} within a domain and gradually explore the benefits and challenges in our survey.

This paper is an overview assessment of the availability (A) of Global Services Mobile Communications (GSM) of the six geopolitical zones (North West, North East, North Central, South West, South East and South South) of Nigeria in the Sub-Saharan African Continent. We approach the problem of Quality of Services (QOS) with Unavailable Second (UAS) constraint from the network operator’s perspectives. The ratio of measured availability to unavailable seconds (UAS) assessment method measures the network installed capacity, base stations and active voice subscription, range of operation of the packet optimized optical transport network solutions. The choice of a hybrid network gives us a bird-eye view of the IP only End-to-End Transport layer due to its complete transparency. The five-year assessment on the coverage range with special consideration given to factors like zones of the country, environment and base stations where it is deployed, active voice subscription and internet services. The results reveals that the operations of the major giants are in order [MTN, GLOBACOM, ETISALAT and AIRTEL] over the past five years within a Sub-Saharan African Environment.
