Network Diagram Software Physical Network Diagram

ConceptDraw Network Diagram Software is ideal for network engineers and network designers who need to draw Physical Network Diagrams.
This interactive voice response (IVR) diagram sample shows the Voice over IP (VoIP) signalling protocol stack. It was designed on the base of the Wikimedia Commons file: Pvoip.gif. [commons.wikimedia.org/ wiki/ File:Pvoip.gif]

"A VoIP phone or IP phone uses Voice over IP technologies for placing and transmitting telephone calls over an IP network, such as the Internet, instead of the traditional public switched telephone network (PSTN).
Digital IP-based telephone service uses control protocols such as the Session Initiation Protocol (SIP), Skinny Client Control Protocol (SCCP) or various other proprietary protocols." [VoIP phone. Wikipedia]
The IVR diagram example "VoIP protocols" 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.

Quality Management System

ConceptDraw PRO diagramming and vector drawing software extended with Total Quality Management (TQM) Diagrams solution from the Quality area of ConceptDraw Solution Park perfectly suits for development and visually representing a Quality Management System.
The vector stencils library "Rail transport" contains 8 clip art images for creating train, tram, railway and rapid transit illustrations, presentation slides, infographics and webpages using the ConceptDraw PRO diagramming and vector drawing software.
"Rail transport is a means of conveyance of passengers and goods, by way of wheeled vehicles running on rails. It is also commonly referred to as train transport. In contrast to road transport, where vehicles merely run on a prepared surface, rail vehicles are also directionally guided by the tracks on which they run. Track usually consists of steel rails installed on sleepers/ ties and ballast, on which the rolling stock, usually fitted with metal wheels, moves. However, other variations are also possible, such as slab track where the rails are fastened to a concrete foundation resting on a prepared subsurface.
Rolling stock in railway transport systems generally has lower frictional resistance when compared with highway vehicles and the passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facilities. Power is provided by locomotives which either draw electrical power from a railway electrification system or produce their own power, usually by diesel engines. Most tracks are accompanied by a signalling system. Railways are a safe land transport system when compared to other forms of transport. Railway transport is capable of high levels of passenger and cargo utilization and energy efficiency, but is often less flexible and more capital-intensive than highway transport is, when lower traffic levels are considered." [Rail transport. Wikipedia]
The vector stencils library "Rail transport" is included in the Aerospace and Transport solution from the Illustrations area of ConceptDraw Solution Park.
