Building a network architecture must answer to organization needs, but also to two major elements which are the need for dependability and performance. By performance, we must understand the ability to meet an immediate need and the ability to scale without reducing the performance of the whole as new elements are added to the network infrastructure. This last point is covered by Capacity Planning domain.

翻译：建设网络架构必须满足组织需要,但也要满足两个重要因素,即可靠性和业绩需要。 通过绩效,我们必须理解满足当前需求的能力和在不降低整体绩效的情况下扩大规模的能力,因为网络基础设施增加了新的要素。 最后一点由能力规划领域涵盖。
