Functionality – To designers , the network should work and meets the particular requests of the network users only. Thus the functions, applications, capability and quality of different services are only concerned by both the designers and users.
Scalability – The network should be able to be available for the growth of the organization, the workstations, and facilities. Then more users and applications may be expanded.
Adaptability – It is concerned with the ability of future technologies application for the network on both hardware and software technologies. For instance, if the network cable is used with coaxial 10Base-2 (IEEE802.3), it will be only limited with this standard and speed. The adaptability is seriously limited to the flexibility for future technologies application.
Manageability – Besides the consideration with the users on the network, the designers think that the manageability is one of the main consideration factors. To ensure the ongoing stability of operations and availability of resources of the network. How many and which users may be allowed to use at what time, what group with trustee and what applications? The designers must have the manageability to properly control the network using.
Cost-effectiveness – The designers should be responsible to balance the costs consumed and the benefits provided by the network, the cost-effectiveness is one of the main concerns. It is foreseeable to relying on the continuous rise of the business activities with the electronic data such as emails and e-commerce and the developing costing increase. Thus it is importance to achieve the cost-effectiveness.
