對波分復用網絡上運行因特網協議的有關研究作了綜述。采用光路交換的波分復用網絡，側重于設計的三個方面：第一是虛拓撲設計，包括保護設計和重構算法；第二是業務量疏導算法，單個光波長能提供巨大的帶寬，而業務的傳輸速率通常低得多，則需要將低速業務適當地并入波長，稱為業務量疏導，以獲得良好的網絡性能并降低成本；第三是網絡抗毀。最后，對進一步的研究作了討論。

Abstract In this paper, an overview of research on the IP over wavelength division multiplexing networks using optical path switching is presented. Three aspects of the design are emphasized. The first is the design of virtual topology, including protection design and reconfiguration algorithms. The second is on the algorithms for traffic grooming. An optical wavelength can provide huge bandwith, but the transmission rates of the services are usually much lower. Low rate services should be appropriately merged into the wavelengths in the network, which is called traffic grooming, to obtain good network performance and lower cost. The third is on the network survivability. Finally, problems for further research are discussed.
Key words IP over WDM; virtual topology reconfiguration; traffic grooming; network survivability
