nt for the messages in the network. Another point of view here to mention is the capacity of a controller to create a network that can redistribute over many sites/destinations. This will be beneficial to the virtual boxes to communicate amongst them. In order to optimise this utility, controller must provide automation of network propagandas to migrated servers and storage. Network Functionality To ensure that security is not compromised at any aspect, it is prevalent for providers of cloud-based services like AWS, ZOHO, and Tata, to isolate one tenant from another. Network functionality is a topic for the open source service providers for the cloud but with time it has been taking the enterprise firms in its storm cloud (pun intended). Like we have to accept the terms and conditions of any service/product we download or purchase on the internet, to ensure the data of our agreement is secure, the firms need to keep one client data hidden from the other ones. Generally there are 2 environments to run a product in, production and testing. The IT firms nowadays prefer programmers to develop their apps in production environment without the disruption of the network flow. In order to fulfil the above mentioned conditions in an effective manner .Software Defined Networking should make sure that the VNs are completely air-gapped from each other and should be controlled from a central main server rather than being distributed and should make sure that the system settings are by default applied and not to be applied manually It is like creating an air-gap between the clouds of information which one user to another. To allow the flows to be routed, it is extremely necessary for the controller to handle any decisional scenario while considering multiple header fields. Like power path software available for EMC networking traffic modulation, it is also relative for controller to find out multiple ways for traffic flow amongst various links from source to destinations. This ability also solves the issue in STP and enhances t
