A New Approach of Multicasting in Cloud Computing .

Cloud Computing is the emerging and prominent technology in IT world. Rather than setting up, the infrastructure, platform and services separately for each and every IT industry, are kept collaboratively, which can be accessed by numerous users, in turn reduces the cost of setup and maintenance. Numerous organizations access the services, use the infrastructure and platform from the communal data centre’s that may lie beyond the reach of the organization. Accessing the data from these data centre’s necessitates secure communication. While adopting the Cloud Computing Environment, security issues are the major concern for IT industries. Moreover, authentication is required to validate the Client to the Service Broker. In this paper, we have proposed Third Party Authentication, which registers the new clients as well as authenticates the already registered clients. This paper also aims to add a new functionality at the end of Service Broker. For Service Management, we proposed Multi Client broadcast Service (MCBS), by which the Service Broker multicasts and schedule the services, in response to the same kind of service requests sent by multiple clients , under the consideration of various parameters, including network delay, bandwidth available and number of hops between client and Service Broker, service request size and cost. MCBS is integrated with service scheduling based on Round Robin, Priority scheduling.
