跨层设计（Cross-layer design， CLD）是一种新的网络架构范式，它允许我们通过优化传统网络层的边界来更好地利用网络资源。先前的工作表明，将CLD应用于移动多媒体通信系统可能会导致显著的性能改进。在本文中，我们还考虑了硬币的另一面，即CLD引入的额外计算和通信开销。我们使用一个无线多用户视频流示例来评估跨层优化的性能改进和成本。
Cross-layer design (CLD) is a new paradigm for network architecture that allows us to make better use of network resources by optimizing across the boundaries of traditional network layers. Previous work has shown that applying CLD to mobile multimedia communication systems may lead to significant performance improvements. In this paper we also consider the other side of the coin, i.e., the additional computation and communication overhead introduced by CLD. We evaluate the performance improvements and the cost of cross-layer optimization using a wireless multi-user video streaming example.
