Abstract

The orignation of cloud computing has revolutionized the field of computing in term of shared network resources.It has provided new oppertunities for different enterprises to compete in the modern days era to provide the shared network resourses amont different end nodes (Host Networks) by using virtualization techniques.On the other hands the modern days cloud computing has completely over thrown the culture of private data centers by saving extra cost and infratracture hazards with better options for end nodes (Host Networks) to select target enterprises (network resource providers) depending upon their network resorce requirements and applications.On contarary of all above textuar represented above in the favour cloud computing have three important issues to be mentioned as (1) Security (2) data load managing in data centers virtually shared among the different end networks (3) Throughput and Efficiency.All above mentioned issues requires a centerlized controller as mentoned in this research article namely SDN(Software Defined Networking),with centerilized control and separate control plan and data plan which can enhance the system parameters (Bandwidth,throughput,end to end delay and etc).This research article inroduces a noval approch by indroducing DLBA(Dynamic load balancing algorithum) technique to enhance bandwidth by load balancing among different data residencial devices groupped in data cenetrs.The results showed that the efficiency of shared network resource cloud computing get boasted under the influenced of DLBA with SDN controlled environment.

Key words: SDN, Cloud Computing, End nodes, DLBA(Dynamic load balancing algorithm), Bandwidth.
