Case Study: My Experience With Management

Software defined networking (SDN) is a new concept which aims to optimize the working of a network and improve its efficiency drastically. Note that in SDN, there exist a central control layer which operates by controlling the flow of data and the related application of bandwidth and other restrictions. Therefore, it is right to state that SDN controller functions as a virtual brain of the network and provides administrators a view of the overall network in the best way possible. The work of SDN is to monitor the flow of traffic quickly and instruct the concealed systems such as routers, switches and other network gear on how the network traffic should be handled. Such functions enable the network engineers to respond fast to changing the business needs and shape the traffic flow, without finding and manipulating the individual switches.
With the software defining networking is the brain of the network, it serves as a connection between two stages. Note that the stage which is above the controller is said to be application layer, and all the data which travels to this level is known as northbound. On the other hand, the information which flows below the application layer is referred to as infrastructure and all the info which go to this level is said to be southbound. An application programming software (API) refers to the set protocols and tools which are applied to develop software applications. It helps to express software in terms of its different components such as inputs, outputs, and operations. The northbound APIs dictate to the applications on top while the southbound APIs communicate with the routers and switches below in SDN.
When you employ software defining networking, you will realize many profits like minimizing on the capital as well as reduction of the operational costs. With automation, optimization strategies and functional separation, one can achieve significant cost savings. It is right to understand that SDN has made it possible to scale up or scale down of network operations fast as result of high reliability in network working and computerized interface and switches
It is right to understand that the use of software defined networking has made is easy to alter the traffic loads fast, in a dynamic wat and using minimal amount of cash as possible. In a nutshell, SDN is aimed at forming a link between the network intelligence part and the physical hardware part without compromising on its working and effectiveness. It is right to learn that reconfiguration takes a lot of time, cash and require manual management which is why one needs to use SDN to cut down on these requirements in the best way possible. Depending much on vendors, complexity and failing to scale up or down quickly are loopholes in networking which have been brought to an end by the use of software defining networking.
