Software Defined Network For File Sharing

The customer required that each workstation have at least 256 GB to 500 GB of local storage. They also wanted a file server on the network to protect data in case a workstation went down. This server will be networked into allow file sharing between devices and have available 40 GB to start. These network upgrades, the greater use of applications, and file sharing will require more protection; a new firewall programmed to filter packets and analyze external requests and direct requests and traffic to the right application.

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

Different Sectors of the work force who are heavily reliant on the networks for their core operation like the Banking, telecom, media, healthcare etc. are finding SDN as a solution to reduce their CAPEX and OPEX. SDN enhances the integration, management, and analysis of big data.

A major advantage of networks is that users are not required to transfer their data to an external drive (flash drives, CDs, etc.) in order to share the data among other users in the same network, this can be done by the network utilities embedded in the operating system. In addition to data, users in a network can share peripheral devices such as printers,

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

Routing lies at the core of any NDN architecture. NDN projects have proposed diverse solutions for routing. In this survey, I present a list of major NDN routing projects and the comparative analysis of four proposed routing models based on performance evaluation factors. My perspective on the requirements of ideal content routing model is introduced based on results of the survey.

This foundational course covers local area network topics including rationale for networking, the open systems interconnection (OSI) model, common network topologies and architecture, client/server concepts, basic hardware devices and usage, and basic networking security concepts.

This offers 32 hosts per subnet, but yet again the first and last host per subnet are reserved and cannot be used. This offers 30 usable hosts per subnet, which is adequate for the number of hosts on the network.)

In the SDN architecture, the control and data planes are decoupled, network intelligence and state are logically centralized, and the underlying network infrastructure is abstracted from the applications [1]. This is the definition of SDN given by Open Network Foundation (ONF).

With the Internet, users have been able to access information faster than ever. Today, users have the ability to utilize cloud technologies to access information and services. Users no longer have to rely on the processing power of their personal computer (PC) to complete task or limit the ability of accessing pictures or document to a physical location such as their hard drive on their PC. The Internet is a large network that is continues to provide more services and opportunities. The Internet is support by a large network of routers, switches, and servers. Understanding how to network terms and utilization will continue to allow business and user to optimize the utilization of the Internet and cloud computing.

The main objective of this project is to enhance the security of a network using various modern day technologies.

The implementation of this project makes use of a lot of modern technologies. However, the state of art technology in this project is Software Defined Networking [1]. In the Networking community, SDN

The controller in the SDN are centralized instead of distributed and it have a global view of the network and the network administrators can adjust the traffic flows all over the network if there is need of some change. SDN is also described as a model which represents a client-server relationship with the controller. In SDN the service customer can send or receive the data with the help of the network resources and the network servies can be managed by the controller. The responsibilities of the service provider include virtualization and orchestration of the resources which could be used by the customers. One of the main problem to be solved in most of the network areas is security. For SDN the security should be in the basic architecture also it should be provided as a service to the users in order to shield the privacy and the integrity of the information flowing. In the SDN architecture we can secure the network in various ways such as by controlling the SDN controller in very tight manner. In case of any attack where the SDN controller and the network goes down

The SDN layer essentially acts a virtual software switch or router in place of (or in conjunction with) the physical network devices. Software from outside the devices takes over the job, instead of software embedded in the routers and switches managing the traffic. The network layout, or topography, is no longer rooted in the physical. Instead, it 's flexible and adjustable to the systems’ needs on the fly. SDN promises to solve both cost of labor performing manual maintenance and administrative tasks in one single blow to the status quo. Traffic engineering problem for SDN controller is to route the traffic in such a way that the delay and packet loss at link are minimized. In existing scenario SDN controllers are deployed incrementally. In proposed system SDN controllers are deployed in tree like structure such that lower level controller is controlled by upper level controller so that all the network is controlled by single SDN controller centrally. Making possible to centralized control over the global view of network with improved architecture will be considered.

Network management is a concept analysis which is being use on different tools, techniques and systems to help people in dealing with numerous devices or network. Fault, Configuration, Accounting, Performance and Security management short for FCAPS. It was created by the International Organization for Standardization (ISO) to help in allowing people around the world to better understand the major function of network management. It will be explain below what each of these management does and how it helps in maintaining the whole network management
