Activity on Node Network Diagramming Tool — Activity Network and Project Evaluation and Review Technique, or PERT, charts are a way of documenting and analyzing the tasks in a project.
This sample shows the Activity on node network diagramming method. It was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Seven Management and Planning Tools solution from the Management area of ConceptDraw Solution Park.
Star is a basic computer network topology in which all nodes (computers and peripheral devices) of the network are connected to the central hub or switch with a point-to-point connection, forming a physical network segment. Such network segment can function separately or as a part of complex network topology. The switch is a server, the peripherals are the clients. The large workload and functions of network management are entrusted on the central computer, all information exchange goes through it, so it must to be obligatory the most powerful.
The star network topology is a simple topology for design and implementation. Its advantages are high performance, flexible administration capabilities, simplicity of adding additional nodes and search of faults, the fact that a failure of one workstation doesn't affect the work of entire network. But the failure of central hub will result the failure of whole network or network segment - it's the main disadvantage. Use the ConceptDraw DIAGRAM with Computer and Networks solution to designing Star Network Topology Diagrams fast and easy.
A Mesh Network Topology is a computer network topology built on the principle of cells. The network workstations are the mesh nodes, they are connected to each other, usually to the principle "each with each" (a fully connected network) and interact in the distribution of data in a network. Each node relays the data for the network and can take the role of switch for other participants. Mesh Network Topology is sufficiently complex to configure, but however it provides a high fault tolerance, has a capability for self-healing and is considered as quite reliable. Large number of nodes' connections assures a wide selection of route of following the traffic within a network, therefore the breaking of one connection will not disrupt the functioning of network as a whole. As a rule, the Mesh Networks are wireless.
The Mesh Network Topology Diagrams of any complexity and Wireless Mesh Network Diagrams are easy for construction in ConceptDraw DIAGRAM diagramming and vector drawing software using the tools of Computer Network Diagrams solution from Computer and Networks area.
A Tree network topology (Hierarchical topology) is a hybrid network topology that contains the combination of two or more star networks connected via bus networks. Each star network is a LAN (local area network) with central computer or server and workstation nodes connected to it. The central computers of star networks are connected to a main cable that is called a bus. Each node of the Tree network can have an arbitrary number of child nodes, you can easy add/remove the separate workstations and even the whole star networks, the failure of one workstation will not affect the work of others. This topology is ideal solution when workstations are located in groups within a small physical region, rarely is used in WAN configurations.
Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park contains templates, samples and numerous libraries of predesigned vector stencils of computer network devices and equipment, which can be effectively used for designing various network topologies diagrams, including Tree Network Topology.
3D Network Diagrams are very popular diagrams in the field of network technologies. They have more visual, clear, attractive and understandable look than 2D. ConceptDraw DIAGRAM gives the opportunity to draw the professional looking 3D Network Diagrams easy, quick and effective.
This example shows the 3D Network Diagram. It was created in ConceptDraw DIAGRAM using the 3D network elements from the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park.
Bus Network Topology is a network topology that represents one shared cable (called a bus or backbone) to which are directly connected all workstations or computers of the network. At the ends of the cable are situated the terminators for prevention the signal reflection. All workstations at Bus Network Topology have equal rights and transfer the information sequentially, one after another. The message sent by one of workstations is extended on all computers of the network and each computer checks to whom it is addressed, if for him, then processes it. Addition of new subscribers to the "bus" is quite simple, the failures of individual computers are not dangerous, and the lack of a central subscriber even more increases its reliability.
Computer and Networks solution included to Computer and Networks area of ConceptDraw Solution Park offers templates, samples and numerous vector stencils libraries that can be used to effectively design different physical and logical network topologies diagrams for wireless and wired computer networks, including Bus Network Topology.
Network topology is a layout of various elements of computer network, such as nodes, links, routers, etc. It is a network topological structure which can be depicted logically or physically. Physical topology shows the physical location of network's components and cable connections between network nodes. Logical topology describes the data flows, the circulation of signals in physical topology. The physical and logical topologies for two networks can be identical, while their physical interconnections, the distances between nodes, transmission rates, and/or signal types may be differ.
ConceptDraw DIAGRAM with Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park lets you design physical and logical network topology diagrams for wireless and wired computer communication networks located in various premises, including the hotels. You can easy design Hotel Network Topology Diagram, diagrams depicted LANs and WLANs, and also any of eight basic topologies (Point-to-point, Star, Bus, Mesh, Ring, Tree, Hybrid, Daisy chain).
This sample shows the activity on node (AON) network. The social network analysis (SNA) is the analysis of the social networks, it analyzes the social relationships in terms of network theory that uses nodes and ties. The nodes represent the activities and are displayed as circles labeled with the activity number and completion time in brackets. The nodes are sequentially connected, the ties are represented as lines.
Network diagram is effective tool for representing and description the network knots and connections between them in comprehensible graphic view, for studying and analysis them. The network administrators and engineers actively use Physical Network Diagrams and Logical Network Diagrams, which are both indispensable when developing and documenting new networks, and managing existing ones. Network diagrams let clearly represent the network configuration and structure, used protocols, addresses, and also names of network objects. Physical Network Diagrams depict the information about telecommunications data, servers, location of network equipment and number of network users. Logical Network Diagrams describe about logical network structure.
It is useful to use the ready sets of network clipart, pictures and symbols for indication the network knots on a diagram, such as developed by professionals and offered in large quantity by Computer Network Diagrams solution from ConceptDraw Solution Park.
