Intelligent Services Gateway (ISG) network.
Computer and Network Examples
Intelligent Services Gateway (ISG) is a feature set that is available on the Cisco Routers. ISG provides the session management, the structured framework, the policies for management the various access networks, provides the information about the session bandwidth and network accessibility.
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 and examples to help you design the professional looking Intelligent Services Gateway (ISG) network diagrams of any complexity quick and easy.
Example 1. ISG network.
This example was created in ConceptDraw DIAGRAM using the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park and shows the Intelligent Services Gateway (ISG) network.
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).

A waterfall model describes software development process as a sequence of phases that flow downwards. SSADM is one of the implementations of waterfall method. It’s easier to learn about structured systems analysis and design method (SSADM) with ConceptDraw DIAGRAM because this software has appropriate tools for creating data flow diagrams. You can use all the three main techniques of SSADM method with special tools and predesigned templates.
This data flow diagram illustrates the Structured Systems Analysis and Design Method. This method method considers analysis, projecting and documenting of information systems. Data flow models are the most important elements of SSADM and data flow diagrams are usually used for their description. It includes the analysis and description of a system as well as visualization of possible issues.

Nodes of any computer network are somehow organized in a hierarchy or a layout. Some of the common layouts like star network topology are more reliable and some like ring topology withstand high loads better. It is also important to distinguish logical topologies from physical.
This diagram represents a typical view of the star network topology. The star network topology is one of the most frequently used network topologies in the majority of office and home networks. It is very popular because of its low cost and the easy maintenance. The plus of the star network topology is that if one computer on the local network is downed, this means that only the failed computer can not send or receive data. The other part of the network works normally. The minus of using star network topology is that all computers are connected to a single point-switch, or hub. Thus, if this equipment goes down, the whole local network comes down.
