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 v12 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

Network Diagram Software LAN Network Diagrams & Diagrams for LAN Physical Office Network DiagramsLocal area network connects computers and other network appliances within an area, such as office building or a campus. It can be difficult to provide such network without a predesigned plan. For these purposes you can use network diagram software, which helps you to create LAN network diagrams and office network diagrams quickly and effortless. This will speed up your work and you can save the diagram for the future network improvements. The following diagram illustrates a network topology of the small office. LAN configuration has a star topology. The local network joins 8 computers among which are several desktop PCs, laptop, two iMacs and iBook. The end-point devices are divided into three groups. Each group is connected to its hub. There is a network printer and a modem, which are interconnected with other devices through a network server. Each computer on the LAN can access the server through a corresponding hub.
Network Glossary DefinitionWhen talking about engineering, one should define all the terms used, so anybody could understand the topic. Typical network glossary contains definitions of numerous network appliances, types of networks and cable systems. The understanding of basic is crucial for server management, network administration and investigating problems. The network glossary defines terms related to networking and communications. The most of glossary items has their visual representation in ConceptDraw DIAGRAM v12 libraries of the Computer Network Diagrams solution. This illustration presents a local area network (LAN) diagram. It designed to show the way the interaction of network devices in a local network. The diagram uses a library containing symbols of network equipment, connections and the end-point devices such as network printer, hubs, server, modem and finally computers (PC, mac, laptop). This diagram depicts a physical LAN topology.
Mechanical Drawing SymbolsTo maintain big and complex mechanical systems, you need an appropriate education and tools. ItвЂ™s needless to say that mechanical drawing is important part of any industrial project. There are a lot of standard symbols depicting valves, pumps, motors, etc. This drawing illustrates the content of the Fluid Power Equipment library provided by the ConceptDraw Mechanical Engineering solution. The solution is composed from the 8 libraries, containing about 500 elements related to mechanical engineering visualization. it will be helpful for drawing various schemes, charts and blueprints of pneumatic, and hydraulic equipment or other drawing related mechanical engineering. All drawings can be freely resized without loss of quality due to the vector graphics components of its facilities.
Active Directory DiagramIt's no secret that there is a list of skills that every average system administrator should have. And it's important to be able to manage domains via active directory technologies. The best way to keep all the details in mind is to draw a diagram representing users, groups and domains. This diagram represents an Active Directory Services (Active Directory Domain Services). It can be helpful for system and network administrators to organize a network physical and logical elements (domains, data bases, servers, network equipment, end-user computers etc.) into a secure and logical structure. The logical structure of Active Directory is a hierarchical organization of all network components. The data that is stored in Active Directory comes from some diverse sources. The Active Directory diagram created using ConceptDraw Active Directory Diagram solution. It shows allocating group policies and functions assigned to end users. It helps to plan, manage and maintain the certain user access scenario.
Cisco Switches and Hubs. Cisco icons, shapes, stencils and symbolsCisco switches and hubs deliver the best performance, and often used as network solutions for small businesses, enterprises, data centers. Cisco switches are the core interconnect devices of each computer network. The numerous Cisco switches specifically designed for various applications. Network switches are separated for two types: fixed configuration and modular switches. The fixed configuration switches deprecate swapping or adding another module, and vice versa for modular switch.
Campus Area Networks (CAN). Computer and Network ExamplesIf we divide computer networks by scale, we get several main categories. The smallest network is PAN, as it connects personal devices themselves, and as the number of users grows, a local area network can be recognized, and campus area networks (CAN) connects several local networks located within some area like a university or a corporation. Computers connected to CAN share public educational materials and list of CAN network examples includes such prestigious universities like Stanford and Carnegie Mellon. This is an example of a computer network diagram created for a campus area network. It was created using using ConceptDraw solution for the Computer and Network diagramming. The specific of this sample campus network is its distribution. It is rather broad to embrace a big campus territory. This diagram can be applied as a template for designing custom area network topology diagram for a particular educational institution.
Fully Connected Network Topology DiagramThere are several basic topologies including bus, star, point-to-point, ring and a hybrid. Two computers can form a fully connected network topology, and as the number of network nodes increases, the network diagram gets more complicated. This type of topology is also called a full mesh. This is a visual example of a computer network built using a mesh topology. This diagram presents the schematic structure of the full mesh network topology. A common mesh network topology means that each network device is connected with several points in the network, so if the one node of the network goes down, it does not cause an issue with an operability of the entire computer network. In a full mesh network topology, every computer or device in the network is interconnected with each of the other devices in the network.
