Abstract
Big data introduces many challenges from the service provider’s perspective such as increase in latency, delay variance, congestion and network utilization. These days’ users require fast speed contents as well as high connectivity. Users are service aware and dislike network delays. In an attempt to make networks less prone to delays, a bunch of researches do improve throughput enhancement but significant efforts are needed to minimize latency delay and delay variance. New network framework turns into the attractive obligation of this technological age. Latest network Infrastructures such as content delivery network (CDN) and software defined network (SDN) assist to determine today’s user’s concerns. CDN provide Contented Caching and it is valuable practice that Internet Service providers (ISP) utilize at this period. Different cache server cooperates with each other and optimally offers the demanded content to the consumer. Challenges in cooperative Caching are where to place the cache server and optimally route the content to client using cache server. In proposed approach, SDN-based Inter-ISP Caching Technique is aspiring to resolve the difficulty of cache server   placement   which   diminishes the data transmission latency and direction the cache content with optimized mode in the inter-ISP traffic. In proposed approach, it is assumed that different ISPs, which are present in same geographical location, communicate with each other. The specified approach introduces a lightweight algorithm named as Row Based Floyd Warshall algorithm to assist placing the cache server using an optimized method. Cache Controller is a pioneering area to establish the cooperative caching and competently a method to reduce cache miss and recover network throughput with the incidence of cache hit. NS3, which is advance event-based network simulator is being used for this research. Simulation results demonstrate the efficiency of Software Defined Network based Inter-ISP Caching beneath diverse network circumstances.
