They connect people, support services and facilitate access to the things that make the career of the company. To meet the daily demands of a modern business networks are becoming more and more complex.

Net Requirements

Today, Internet-based companies often demand 24 x 7 customer service. This simply means that corporate networks should be available close to 100 percent of the time. They should be smart enough to automatically protect against unexpected security events. Moreover, these corporate networks also be able to adapt to traffic volumes and consistent response times to maintain the application. It is not useful for networks to be built by connecting a large number of separate devices, without careful planning and design.

Building a good network

Well-designed systems do not happen by chance. They result, the result of the hard efforts of network designers and network specialists who place the needs of the network and choose the best way to satisfy the company. Network users usually do not “see” the network complexity. Think of the network as a way to find and use the applications they need.

System Requirements

Most organizations have a limited amount of network needs. Let’s examine the most important.

The network must be available at all times, even in case of hardware failure or overload conditions. The network consistently deliver applications with realistic response times from any device on a device. The network must be secure. It must protect data being transferred through it, as well as data stored on your computer to connect.

The network should be simple to change to accommodate network growth and the changing global business. Because disasters can occur, the solution of problems, no stress. Find and correct a problem to be fast and relatively easy to do.

The main design goals

By studying wise, these requirements in the four main objectives of network design and objectives: scalability, availability, security and administration.

To meet these four major design goals, only be based on a design that allows great flexibility and development.

Hierarchical network design

A hierarchical network design is used to group network devices in different networks. The networks are structured by levels. The hierarchical design of three basic layers: The Core Layer Distribution Layer devices that connects the distribution layer of smaller local networks and the connection of the access layer that provides connectivity to network devices and host end.
