The emerging Wavelength-Division-Multiplexing (WDM) optical network is a promising candidate for next-generation Internet, which provides enormous bandwidth and fast connectivity. Multicast in WDM networks is a fundamental problem which has wide applications including teleconferencing, entertainment distribution, etc. In this project we investigate the multicast and constraint multicast problems in both single-hop and multi-hop WDM networks by studying their computational complexities and devising scalable, high-quality approximation algorithms for them. The developed algorithms significantly improve the network performance and scalability, and the innovative approaches and algorithm techniques developed in this project are also applicable to other routing problems.

新兴的波分复用（WDM）光网络提供了巨大的带宽和快速的连接，是下一代互联网的一个很有前途的候选者。WDM网络中的多播是一个基本问题，它有广泛的应用，包括电话会议，娱乐分发等。在这个项目中，我们研究了单跳和多跳WDM网络中的多播和约束多播问题，通过研究它们的计算复杂性和设计可扩展的，高质量的近似算法。所开发的算法显著提高了网络的性能和可扩展性，本项目中开发的创新方法和算法技术也适用于其他路由问题。
