Computer Network is a collaboration platform for digital gadgets. Virtualization is abstracting layers from underlying Architecture. Virtualization platform provides flexibility, green resource usage and fast deployment of the carrier. Integration of Computer Network and Virtualization Platform Create Network Virtualization Platform. Software-Defined Network (SDN) Provide dynamic and scalable networking offerings to Business Environments Cloud Network and Data Centers. SDN is controlling network infrastructure with the control plane. Security is a challenging problem for the network. SDN comes with Network Programmability and automation. SDN has an advantage, but it contains a new safety issue. SDN is focused on network safety data plane and control. Security Challenges in SDN is Control Plane, Data Plane Attacks. In Controller Layer Attacker at controller Layer, an routing, visitors filtering denying, or allowing unnecessary site visitors. Control plane assault used to drop or lack of manage over traffic policy and Quality of carrier control. Data Plane Attack Attacker can create DOS Denial of Service.

 Abstract: While purchasing online products, our priority is to consider online rating regarding the product. Based on the customer rating of products it can be possible to determine their lifetime, sales and that impacts the ability to be maintained at a certain rate or level of a product in the market. The rating is considered as datasets where they are being extracted from E-Commerce websites. In specific, consider the review content, product ratings and divide product lifetime. While collecting the relevant information from our review data we consider the data into two categories as positive data and negative data. When a user posted a review, we consider the keywords to state the review was good or bad and their rating behaviors, these extracted scores can be correlated with their rating with product popularity. The product popularity can be considered by the total number of purchases of the product and the rating given to the product. It also can be analyzed by product ratings that indicate that raters' ratings are likely to influence product popularity. Taking different e-commerce datasets to extract review content and obtaining relevant information from the review data can analyze and predict the product's early raters and product marketing.
