Software Defined Networking : A Literature Review

[M1] The use of new network technologies allows different organisations to connect with their worldwide counterparts allowing them to get information out quicker and to help create new ideas without being face to face. The use of VoIP and Video Conferencing allows a company to sit down and talk about new ideas even though they are on two completely different sides of the world. Others such as Server virtualisation allows a company to increase their security so that people cannot access their servers easily. Cloud computing can also help companies by allowing them to put files online and have their employees and other managers access it whenever they need to. However there are some downsides to some of these technologies. If a cloud computing server is hacked the company could lose some important files and the hacker may be able to gain access whenever they want. Also video conferencing may not always work due to time and bad connection therefore groups may not be able to create new things together and would have to stay within their own

amid this configuration we tend to look for guidance from them as data, control, and application planes. At base, the data plane is included system segments, whose SDN Data ways uncover their abilities through the Control-Data-Plane Interface (CDPI) Agent. On top, SDN Applications exist inside of the application plane, and impart their needs by means of northward Interface (NBI) Drivers. inside of the centre, the SDN Controller interprets these needs and applies low-level administration over the SDN Data ways, while giving pertinent data up to the SDN

Typical data centers can occupy from one room to a complete building. Most equipment are server-like mounted in rack cabinets. Servers differ in size from single units to large independently standing storage units which are sometimes as big as the racks. Massive data centers even make use of shipping containers consisting of 1000’s of servers. Instead of repairing individual servers, the entire container is replaced during upgrades.

Online solutions alternative to dial-up are also technological factors that may determine competitiveness as an alternative mean can basically cut the cost of the company. According to (2004), a remote access solution could provide significant cost savings by allowing the engineers, who were responsible for maintaining the aircraft, to access essential information on the company's systems from wherever they were in the world, using remote web access.

Another positive aspect, that business and government sectors are using the internet communication service. This service have allowed business to work and invest via internet networking .For instance, currently many business companies are sold or advertise their products using networking technology to contact their costumers or other commercial sectors . This is because of the consideration that the time and the cost could be less . In fact the communication network is the main factor of any successful business in today world market . According to ONS: The internet purchases by businesses rose 64.6 per cent, from £37.9 billion in 2003 to £62.4 billion in 2004.(the office for National Statistics ).

As a business grows, it might expand to multiple offices across the country and around the world. For a growing business firm, limited number of offices is typically not adequate. With adequate capital and personnel, many business firms desire to set up multiple offices to attract different areas of customers (Lock, 2007). To keep business running efficiently, the employees working in those locations need a reliable, secure and fast way to share information across computer networks. With the help of networking technology, one firm can install a network so that all the employees and customers of separate offices can communicate, and access

Software defined networking is a new concept that redefined the current network device architecture and the way they behave. Due to the exponential growth of the Internet and services attached to this worldwide infrastructure, a number of issues have cropped up in modern day networks. This paper discusses a few of these limitations and how the software defined networking approach tries to alleviate them. OpenFlow, released in the year 2008, is a commercially viable implementation of this concept that is being well received by the networking industry at large. The paper also discusses the OpenFlow protocol, its implementation and the challenges facing its widespread acceptance

In order to succeed today, organizations that are competing in global markets are increasing rapidly. The increased use of technologies such as the Internet, intranets, and extranets will definitely revolutionize how businesses will operate and how they will use computers to compete. The Internet and related technologies and applications have changed the ways companies operate their businesses processes and activities. For example, companies can network their offices and share data to be more effective and efficient. However, excessive use of the Internet, intranets, and extranets also create intense

The increasing number of mobile devices, virtualization of servers and emergence of cloud services has driven the networking industry to further examine the architectures of traditional network. Most of the traditional networks are hierarchical, arranged in a tree structure and built with Ethernet switches. This design was useful when client-server computing was being used, but this kind of static architecture will not be useful in dynamic computing and storage requirements of today’s data centers, carrier environments and campuses. Some of the important computing trends that drive the need of a network include:

Software-Define Network (SDN) has emerged as a very promising network architecture in recent years. It largely simplifies the network logic and makes the network traffic more controllable by decoupling data plane and control plane out of the traditional network architecture, and having centralized controllers to control network switches. The significant difference from the traditional network architecture is that the network traffic routing is centralized into controllers such that network switches are only need to perform forwarding, instead of complicated routing protocols. The centralized controlling scheme of SDN has many novel and important capabilities such as global view of the network, software-based traffic analysis, and dynamic reconfiguring of network forwarding rules. The SDN has attracted the interests of many attackers due to the use of centralized controlling architecture and many security flaws are remained to be addressed yet. Distributed Denial of Service (DDoS) attack is one of the most frequent network attack that no effective countermeasure is acknowledged in traditional network. Fortunately, the characteristics of SDN bring us new chances to effectively against DDoS attacks. In this paper, we are going to discuss the classifications and characteristics of DDoS, analyze the advantaged capabilities of SDN architecture, and present a survey of the methods to detect and prevent DDoS attacks using SDN, and review the studies of SDN as a victim of

This white paper will bridge both Cloud Networking and Data Architecture on how it currently fits the organization, WideOpenWest (WOW!) privations. A majority of new organizations are trending to the very popular Cloud networking that can also “join-in” different types of data architectures. Huge corporations are using terms like “Big Data, … a popular term used to describe the exponential growth and availability of data, both structured and unstructured.”(SAS, 2015). Other names include, “data warehousing” or, “data mining”. How is Cloud networking the Data Architecture designed into WOW!’s current IT development, what platform is needed, and when implemented how will it impact on the future of

Moving Towards Software Defined Cellular Networks : An Idea A Solution And A Critique DEEPA MARTOLIA : CS14MTECH11004 Abstract—Since last two decades Software Defined Networking (SDN) has become one of the prevailing topics in the area of networking. SDN pervaded from wireless to cellular and the reason behind its widespread application in various domains of networking is because of its ability to decouple control plane and data plane into two separate components, which provides automation to the network function and gives relief to the operator from manually configuring each network component.

Using OpenFlow: This research shows about the implementation of OpenFlow in software defined networks. Main aim of this exp

Within this context, we conducted our graduation project . We make use in this work of packet processing challenges in regards with OpenFlow/SDN requirements to build a framework for an optimal packet classification . Our framework pre-processes OpenFlow rules by investigating the relation between rules and then generates a packet classification schemes which are aware of the underlying hardware architecture and also network services priorities . Added to that , the framework communicates with the target physical platform in order to map the computed classification structure and place the the OpenFlow rules .

In an ever-evolving world , people come up with new idea each day , some of them are in the field of robotics , some in computer security and some are in computer networks. Well the Network industry has risen up and been on a peak ever since 2008 , with new technologies coming by every year , but they had to slow the roll down of such innovations in the field just to make the previous technology have a good life span and make devices adapt to a certain technology for a certain time .
