Abstract:
Big data introduces many challenges from the service provider’s perspective such as
increase in latency, delay variance, congestion and network utilization etc. These days users
require fast speed contents as well as high connectivity. Users are service aware and dislike
network delays. In networking, bunch of effort has been made in throughput enhancement but
significant efforts are needed to minimize latency delay and delay variance etc. 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, assumed different ISPs which are present in same geographical
location, communicate with each other. Specified approach, introduce light weight algorithm
named as Row Based Floyd WARSHALL algorithm assist to put the cache server in optimized
method. Cache Controller is as well pioneering to established the cooperative caching and
competently way the cache content through the lessening of 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 toil. Simulation results demonstrate the efficiency of SDN-based Inter-ISP
Caching beneath diverse network circumstances.
