Software Defined Networking “DDoS mitigation with SDN” (Bachelor thesis)
Αλίτσκας, Μάριος
Traditional networks nowadays have become too complex, proprietary, difficult to manage, and closed. In a world driven by applications and services, on the network level it is difficult to innovate and follow the agile methodologies used for the creation of new services within a data centre, on interconnected data centres, or within enterprises, and most important in some cases the network can become a barrier to the continued growth of the internet traffic. SDN is a new emerging paradigm of networking and is about to change the way a network is, built and operated, in order to achieve agility. The network is evolving and will no longer be proprietary, closed and difficult to program, but elastic, flexible and agile. SDN is transforming networks towards an open and programmable era. SDN gives more power and control over the infrastructure, allowing customization, optimization, and it is reducing the overall capital and operational costs for a business, allowing them to explore new opportunities and methodologies. With the introduction of SDN, new security capabilities are expected to be identified and explored within the next years to come. Security is one of the areas that SDN can add value, alongside with the development and standardization efforts that are driving the concept of the SDN.
