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).

Electrical Symbols — Switches and Relays →

In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. The mechanism of a switch may be operated directly by a human operator to control a circuit (for example, a light switch or a keyboard button), may be operated by a moving object such as a door-operated switch, or may be operated by some sensing element for pressure, temperature or flow. A relay is a switch that is operated by electricity. Switches are made to handle a wide range of voltages and currents; very large switches may be used to isolate high-voltage circuits in electrical substations. 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.Electrical Symbols — Switches and Relays *

Hybrid Network Topology →

Every corporate network is unique, though there are guidelines and best practices in developing networks. As it is quite difficult to implement a pure topology within a company, using a hybrid network topology is considered a better solution. As a rule, such network assembles advantages and features of source topologies. This diagram is an example of the Hybrid network. This type of network topology means a conjunction of other network topologies. Such as star-bus, ring-mesh topologies, etc. It should be obviously diverse networks. The final computer network inherits both advantages and disadvantages of its ingredients. Using the ConceptDraw Computer and Networks solution including vector graphic libraries and templates one can develop professional custom network diagrams of any topology and complexity.Hybrid Network Topology *
