Network VOIP. Computer and Network Examples

Voice-over-Internet protocol (VoIP) is a protocol of the voice communications and multimedia sessions through the Internet or other packet-switched networks. VoIP systems use the data compression techniques, encapsulated in a data-packet stream over IP. They allows users to use regular telephone networks through any internet service provider and anywhere. VoIP is also called IP telephony, Internet telephony, Voice over broadband (VoBB). This example was created in ConceptDraw PRO using the Computer and Networks Area of ConceptDraw Solution Park and shows the VoIP Network. Read more

Hotel Network Topology Diagram

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 PRO 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).

Network Topologies

Network topology is a topological structure of computer network, which can be physical or logical. The physical topology depicts location of different computer network elements such as computers, cables and other devices. The logical topology visually displays network dataflows from one device to another. Sometimes network logical and physical topologies can be the same. ConceptDraw PRO diagramming and vector drawing software is powerful for drawing network maps and network topologies diagrams of any kinds and complexity thanks to the Computer Network Diagrams solution from the Computer and Networks area. ConceptDraw STORE proposes collection of network icons libraries and a lot of Network Topology Diagram examples, samples and templates which were created at ConceptDraw PRO software specially for Computer Network Diagrams solution. There are six basic types of the network topologies: Bus, Star, Ring, Mesh, Tree, Fully Connected. You can fast and easy design professional-looking diagram for each of them using the ConceptDraw PRO tools. There are plenty of web Visio-like diagramming software available. Web based diagrams software can be powerful, but sometimes it is essential to have desktop software. One of the most advanced diagrams tools like Visio for Mac OS is ConceptDraw PRO app. Read more

ConceptDraw PRO Network Diagram Tool

Computer network diagrams visually depict the nodes of computer networks and connections between them. Diversity of Network Diagrams includes Wireless network diagrams, Network wiring diagrams, LAN network diagrams, Network WAN diagrams, Network topology diagrams, Network cable diagrams, Logical network diagrams, Network security diagrams, Diagram home network, Network physical diagrams, Activity network diagrams, and many others. To construct any of them it is useful to apply a special software with effective network diagramming tools. ConceptDraw PRO is ideal and powerful network diagram tool. It helps you diagram a network or create Computer network diagrams of various types using specialized and task-specific libraries of network components such as computers, hubs, switches, servers, routers, smart connectors, printers, mainframes, face plates, etc. that simulate network architectures, network design topologies and devices (all these shapes are parts of network diagram tool ConceptDraw PRO).

This IVR diagram sample illustrates how ENUM works by giving an example: Subscriber A sets out to call Subscriber B:
1. The User Agent of an ENUM-enabled subscriber terminal device, or a PBX, or a Gateway, translates the request for the number +34 98 765 4321 in accordance with the rule described in RFC 3761 into the ENUM domain 1.2.3.4.5.6.7.8.9.4.3.e164.arpa.
2. A request is sent to the Domain Name System (DNS) asking it to look up the ENUM domain 1.2.3.4.5.6.7.8.9.4.3.e164.arpa.
3. The query returns a result in the form of so called Naming Authority Pointer Resource NAPTR records, as per RFC 3403. In the example above, the response is an address that can be reached in the Internet using the VoIP protocol, SIP per RFC 3261.
4. The terminal application now sets up a communication link, and the call is routed via the Internet.
This IVR diagram sample was designed on the base of the Wikimedia Commons file: Ejemplo ENUM.jpg. [commons.wikimedia.org/wiki/File:Ejemplo_ENUM.jpg]
"Being able to dial telephone numbers the way customers have come to expect is considered crucial for the convergence of classic telephone service (PSTN) and Internet telephony (Voice over IP, VoIP), and for the development of new IP multimedia services. The problem of a single universal personal identifier for multiple communication services can be solved with different approaches. One simple approach is the Electronic Number Mapping System (ENUM), developed by the IETF, using existing E.164 telephone numbers, protocols and infrastructure to indirectly access different services available under a single personal identifier. ENUM also permits connecting the IP world to the telephone system in a seamless manner." [Telephone number mapping. Wikipedia]
The IVR diagram example "Example ENUM" was designed using ConceptDraw PRO diagramming and vector drawing software extended with the Interactive Voice Response Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park. Read more
