在当前通信网络中，不断增长的应用程序对资源的竞争突出了有效的资源分配机制的必要性，以最大限度地提高用户满意度。优化理论可以提供必要的工具来开发这样的机制，将分配网络资源的用户之间的最佳和公平。本文的目的是为有兴趣将优化技术应用于当前通信网络资源分配问题的研究人员提供一个起点。为了实现这一目标，我们首先描述了设计最优资源分配算法所需的基本优化理论工具。然后，我们描述了网络效用最大化（NUM）框架，这个框架已经在网络优化中找到了许多应用，以及初始NUM框架的一些最新进展。最后，我们总结了我们最近在该领域的一些工作，并讨论了开发一个完整的基于优化的资源分配协议的一些剩余的研究挑战。
The continuously growing number of applications competing for resources in current communication networks highlights the necessity for efficient resource allocation mechanisms to maximize user satisfaction. Optimization Theory can provide the necessary tools to develop such mechanisms that will allocate network resources optimally and fairly among users. The aim of this paper is to provide a starting point for researchers interested in applying optimization techniques in the resource allocation problem for current communication networks. To achieve that we, first, describe the fundamental optimization theory tools necessary to design optimal resource allocation algorithms. Then, we describe theNetwork Utility Maximization (NUM)framework, a framework that has already found numerous applications in network optimization, along with some recent advancements of the initial NUM framework. Finally, we summarize some of our recent work in the area and discuss some of the remaining research challenges towards the development of a complete optimization-based resource allocation protocol.
