The digital business is no longer just face the challenge of speed and network performance, but also to solve security problems, network management complexity, high investment costs. Software Defined Network<\/strong> (SDN) has emerged as an advanced solution, brings the ability to control and optimize network infrastructure intelligently, more efficiently than ever before.<\/span><\/p>\n

So, SDN is what architecture SDN, including the floor? How to business can deploy and leverage the maximum benefits of this technology? In this article Lac Viet<\/a> will answer all these questions revolve around the system SDN.<\/span><\/p>\n

1. Overview of Software Defined Network (SDN)<\/h2>\n

1.1 Software Defined Network is what?<\/h3>\n
\n

Software Defined Network (SDN)<\/i><\/b> is a network architecture advanced use software to manage and control the network instead of relying completely on the hardware as in the traditional model.<\/span><\/i><\/p>\n<\/blockquote>\n

SDN represents the shift from the use of the device independent network to a centralized model in which the software take on the main role in the management and network optimization. This brings the ability to better control, more flexibility in deployment, advanced system performance network.<\/span><\/p>\n

1.2 differences between traditional network and network SDN<\/h3>\n

In the context of technology is growing, the difference between traditional network and Software Defined Network (SDN) increasingly clear. Especially for business, the selection of network solutions suitable not only affect the efficiency of operation which determine the ability to adapt to number conversion.<\/span><\/p>\n

Specifically, traditional network is a network model based on the hardware in which the network device (switch, router) to be configured independently. Meanwhile, SDN brings the ability to manage focus, help businesses manage the entire network system through software.<\/span><\/p>\n

2. Architecture, SDN, including the floor?<\/h2>\n

Software Defined Network is built on the system architecture 3 tier clear, in which each tier take on the role and function of different coordination to optimize system performance network.<\/span><\/p>\n
