Network Architecture

Network architecture will help you gain the technical leadership skills you need to design and implement high-quality networks.

 A network architecture is a blueprint of the complete computer communication network, which provides a framework and technology foundation for designing, building and managing a communication network. It typically has a layered structure. Layering is a modern network design principle which divides the communication tasks into a number of smaller parts, each part accomplishing a particular sub-task and interacting with the other parts in a small number of well-defined ways. Layering allows the parts of a communication to be designed and tested without a combinatorial explosion of cases, keeping each design relatively simple.

 The network architecture and design specialization will help you gain the technical leadership skills you need to design and implement high-quality networks that support business needs. You will learn how to design, maintain, and troubleshoot Internet, intranet, and extract connections, including local- and wide-area networks. This specialization will also build your knowledge of developing security and disaster recovery plans. Upon completion of this online degree, you will be well positioned to assume a senior management or team leader role in network management.

 Network architecture is the logical and structural layout of the network, consisting of transmission equipment, software and communication protocols, and infrastructure (i.e. wired or wireless) transmission of data and connectivity between components.

 There are 4 different network topologies: star network, a bus or line network, a loop or ring network, and a mesh network.

 The different topologies can be arranged in different ways, described as LAN (Local Area Network), MAN (Metropolitan Area Network), and WAN (Wide Area Network), where the network extends over a local area (< 1 km), metropolitan (< 100 km), and long distance area, respectively.
