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.
ConceptDraw DIAGRAM is a powerful network diagramming and vector drawing software. It provides the Computer and Networks Area with many Solutions that contain the wide set of ready-to-use predesigned vector stencils, templates and samples to help you design the professional looking Software-Defined Networking (SDN) diagrams of any complexity quick and easy.
Example 1. Software Defined Networking System Overview
On this example you can see the Software-Defined Networking (SDN) diagram that was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park.
The network diagrams designed with ConceptDraw DIAGRAM are vector graphic documents and are available for reviewing, modifying, and converting to a variety of formats (image, HTML, PDF file, MS PowerPoint Presentation, Adobe Flash or MS Visio).

TEN RELATED HOW TO's:
Electronic components have two or more electrical terminals (or leads) aside from antennas which may only have one terminal. These leads connect to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator). Basic electronic components may be packaged discretely, as arrays or networks of like components, or integrated inside of packages such as semiconductor integrated circuits, hybrid integrated circuits, or thick film devices.
26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.

Working with disordered network data can be quite exhausting. Sometimes it's necessary to find a network diagramming software to design Cisco network diagrams that would be easy to use and would be able to export diagrams to various graphic formats. ConceptDraw DIAGRAM is a great diagramming tool that is able to perform all these tasks easily.
This vector library represents a set of 26 objects depicting the manufacturer - standard equipment of Cisco switches and hubs. This is only a small part of the vector graphic objects of Cisco equipment that comprise the Cisco Network Diagrams solution. In full the ConceptDraw Cisco Network Diagrams solution has 15 libraries, containing more then 500 objects to create a Cisco network diagrams. They can be used by IT specialists and corporative IT divisions, system and network administrators to make the visual documentation of Cisco networks topology.

A waterfall model describes software development process as a sequence of phases that flow downwards. SSADM is one of the implementations of waterfall method. It’s easier to learn about structured systems analysis and design method (SSADM) with ConceptDraw DIAGRAM because this software has appropriate tools for creating data flow diagrams. You can use all the three main techniques of SSADM method with special tools and predesigned templates.
This data flow diagram illustrates the Structured Systems Analysis and Design Method. This method method considers analysis, projecting and documenting of information systems. Data flow models are the most important elements of SSADM and data flow diagrams are usually used for their description. It includes the analysis and description of a system as well as visualization of possible issues.

A complete (fully connected) topology is a network topology in which there is a direct link between all pairs of nodes. In a fully connected network with n nodes, there are n(n-1)/2 direct links. Networks designed with this topology are usually very expensive to set up, but provide a high degree of reliability due to the multiple paths for data that are provided by the large number of redundant links between nodes.

A network diagram is used to depict the topology of a computer network or, talking more broadly, any telecommunications network in general. In order for a computer network diagram to be understandable, clearly identifiable icons must be used for each network appliance. Cisco network templates, also called Network Topology Icons, is a brand of symbols developed and used by Cisco. Since Cisco Systems is the largest networking company in the world, it's list of networking symbols is widely recognized and exhaustive.
The diagram of the ISG network topology diagram illustrates the Cisco Intelligent Services Gateway. Since Cicso company offers service providers a possibility to provide control of state and resources in a broadband network, network architects and engineers need some facilities to create ISG topology diagrams.This Cisco ISG network diagram was created in ConceptDraw DIAGRAM using its solution for Cisco network diagrams. The vector library of this solution comprises over 500 icons of Cisco hardware and accessories. They can be used to design LAN, WAN, ISG and other Cisco equipped network diagrams.

There are a lot of structured analysis and design technique methodologies used to describe systems and data sources. To visualize data structures, data flow diagrams can be used for various purposes in the area of software engineering. Nowadays these diagrams are also used in the area of business analysis and information system analysis.
This data flow diagram depicts an account processing system of a typical account department of a small manufacturing enterprise. It shows the data transmission through the order processing to shipping verification. This data flow diagram was created according to standard of Yourdon and Coad notation. The vector graphic objects of Yourdon/Coad notation symbols was delivered by ConceptDraw Data Flow Diagrams solution. The current DFD can be employed as an example of a business process model, representing the set of business events and interactions commonly engaged in a accounts receivable process.
