ITU-T（以前的CCITT）已经成功地制定了固定网络和电话业务的流量工程指南。这一指南是基于一个通信范式，其中包括规范的操作环境，操作域匹配的国家边界，集中控制，和可预测的服务质量。随着新的通信模式的引入、移动的和个人通信服务的日益普及以及运营管制的解除，这些假设正受到越来越多的挑战。因此，21世纪世纪电信的新范例正在出现。在这样的框架中，个人通信服务的持续用户满意度和运营商收入增长要求设计合适的流量工程方法。这些方法应有助于使预期的服务质量与支持一系列服务的网络和基础设施的成本效益规模和运作相协调，并提供一种利用传统/现有电信基础设施投资的手段。文章指出，为了达成合理的ITU-T建议，个人通信网络的流量工程，实践和理论应该是相互支持的。
Guidance on traffic engineering for fixed networks and telephone service has been successfully developed by the ITU-T (formerly CCITT). This guidance has been based on a communication paradigm which has included regulated operation environment, operation domains matched to national boundaries, centralized control, and predictable service quality. These assumptions are being challenged more and more with the introduction of new communication modes, the increasing popularity of mobile and personal communications services, and deregulated operation. As a result, new paradigms are emerging for 21st century telecommunications. In such a framework, continued user satisfaction and operator revenue growth with personal communications services require that suitable traffic engineering methods be devised. These methods should help reconcile the expected service quality with cost-effective dimensioning and operation of networks and infrastructure for supporting a range of services, as well as provide a means for capitalizing on investments in traditional/existing telecommunications infrastructure. The article notes that in order to arrive at sensible ITU-T Recommendations on traffic engineering for personal communications networks, practice and theory should be mutually supportive.
