Network Architect

A network architect designs and builds data communication networks for organisations. These networks range from a small connection between two offices in the same building, called local area networks (LANs), to wide area networks (WANs) spanning across offices in different geographic locations and across countries.

Network architects create the plans for data communication networks by graphically mapping the layout of fibre cables to all the service points or nodes and data flow between the components. They map out the topology of the network which is the entire network structure and work with computer systems engineers who help build the network they have designed. They may build test networks using network modelling tools to determine what hardware and software will need to be used. They decide what routers, adaptors, network drivers, hubs and other hardware should be used, how the cables will be laid and where other hardware will go.

A network architect must be business-minded in determining the most efficient and secure way for information transfer to take place keeping in mind thecompany’s budget, its number of employees and the future needs of the company in terms of scalability. They analyse current and future data traffic to estimate how growth might affect the network. They also need to be practical and may be responsible for determining how to grant the employees of an organization access to the internet and in-house information databases in the most affordable and efficient way. 

Network architects analyse systems for issues and devise inventive new solutions to eliminate problems as they are identified. They must work with computer programmers and network engineers to fix software problems. They rely on their knowledge and experience of hardware, software systems and network platforms to address a variety of business needs within different types of industries, and determine the costs of implementation and maintenance.

Network architects plan the implementation of security patches or other counter measures which must be taken into consideration when designing networks to counteract vulnerabilities. They increase the efficiency of communications of computer systems for a variety of uses, such as banking, finance, sales, scientific research, and more while keeping in mind network safety as a key goal.

The complex nature of the job necessitates that network architects are usually experienced staff with a number of years’ experience working in network administration or with other information technology (IT) systems. They should also have an extensive knowledge of an organization’s business plan so that they will be able to design a network that can help the organization achieve its goals.

What to Study

In order to become a network architect, you typically need a bachelor’s degree in computer science, information systems, computer engineering, or a closely related field. 

Degree: BSc Computer Science – all universities. Each institution has its own entry requirements. 

A person who has obtained a recognised BSc (Eng) or BEng degree is eligible for registration as Engineer in Training. After gaining at least 3 years of appropriate practical experience, a computer engineer may register as a Professional Engineer under the auspices of the Engineering Council of South Africa. 

Postgraduate: BHonours in Computer Science can be followed by MSc and PhD at most universities. It is essential to upgrade knowledge continuously because systems and security threats are constantly changing.

Employment

Demand for network architects will increase as firms continue to expand their use of wireless and mobile networks. Designing and building these new networks, as well as upgrading existing ones, will create opportunities for network architects. However, the adoption of cloud computing, which allows users to access storage, software, and other computer services over the Internet, is likely to cause a decrease in the demand for network architects in some cases. 

Employment can be found in:

• large computer companies
• government departments
• provincial administrations
• insurance companies
• banks
• universities and universities of technology
• self-employment; a registered engineer with the necessary experience and initiative, as consultant
