Software Defined Networking System Overview
Today is observed the extremely active growth in the bandwidth-intensive applications and permanent demand for speed, scalability, and resilience. The traditional networks and data centers are on the limit of their possibilities.
Software-Defined Networking (SDN) is a new powerful concept for decision these problems. SDN proposes to disaggregate the traditional networking stacks that are vertically integrated to customize the network operations for specialized environments and improve network service velocity.
SDN is a special approach to computer networking that allows network administrators to manage network services via the abstraction of functionality of the lower level. It is realized by separating the control plane from the data plane.
SDN is an important step in the evolution to the programmable and active networking. With SDN the network administrators have the programmable central control of the network traffic through the controller, without the physical access to the network's switches. Many networks use switches for sending, receiving and directing data over the network.
The networks with SDN allow to network administrators quickly respond on the changing of business requirements. The traffic can be formed from a centralized control console, there is no need to go out to another building to reconfigure switches individually.
The first supporters of SDN were OpenFlow, OpenDaylight, Brocade. The main application of SDN is the infrastructure as a service (IaaS), it is also used in the consolidated data-center, in traditional and geo-distributed campus networks.

A Virtual network is a computer network that consists of virtual network links, i.e. between the computing devices there isn't a physical connection.
Well known forms of network virtualization are virtual networks based on the virtual devices (for example the network based on the virtual devices inside a hypervisor), protocol-based virtual networks (VLAN, VPN, VPLS, Virtual Wireless network, etc.) and their combinations.
This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Virtual network.

A list of parameters on which networks differ is very long. A large network with a range up to 50 kilometers is called metropolitan area network (MAN), and this type of network can include several local area networks. Metropolitan networks in their turn connect into global area networks.
Here you will see a Metropolitan Area Network (MAN). This is an extensive network which occupies a large territory including a few buildings or even the whole city. The space of the MAN is bigger than LAN, but lower than WAN. MAN comprise a lot of communication equipment and delivers the Internet connection to the LANs in the city area. Computer and Networks solution for ConceptDraw DIAGRAM provides a set of libraries with ready-to-use vector objects to design various kinds of computer networks.

There are many ways to describe a database structure. One of the most usual is to draw an entity relationship diagram (ERD) using a Crow’s Foot notation to represent database elements. If you don’t want to draw it on paper, you should use an appropriate software.
An entity-relationship (ER) diagram is used to show the structure of a business database. ERD represents data as objects (entities) that are connected with standard relationships symbols which Illustrate an association between entities. ERD, there is a wide range of ERD notations used by data bases architects for reflecting the relationships between the data entities. According to the crow’s foot notation relationships are drawn as single labeled lines designating a certain kinds of relationship. Crow foot notation is a most frequently used ERD standard, because of improved readability of diagrams, with a more accurate use of space on the page._Win_Mac.png)

A Daisy Chain is the simple computer network. It is the easiest way to add more Ethernet devices into the network. In the Daisy Chain network one computer is connected to the next without any intervening devices, thus the message is sent from one computer to the next and then to the next and so on. A Daisy Chain can be linear or ring
