Computer network architects typically do the following:

• Create plans and layouts for data communication networks
• Present plans to management and explain why they are in the organization's best interest to pursue them
• Consider information security when designing networks
• Upgrade hardware, such as routers or adaptors, and software, such as network drivers, as needed to support computer networks
• Research new networking technologies to determine what would best support their organization in the future

Computer network architects, or network engineers, often work with their organization's chief technology officer (CTO) to predict where the organization will most need new networks. They spend most of their time planning these new networks. Some computer network architects work with engineers such as computer hardware engineers who help build the network a network architect has designed. Network architects are often experienced staff and have 5 to 10 years of experience working in network administration or with other information technology (IT) systems.

Computer network architects also create models to predict future network needs by analyzing current data traffic and estimating how growth will affect the network. They also keep up to date on new hardware and software technology and test how it can improve network performance. In addition, computer network architects have to keep security in mind and when network vulnerabilities arise, implement security patches or other countermeasures.
