光网中路由与波长分配问题的一种新模型

A new model for routing and wavelength assignment in optical networks

路由与波长分配问题是波分复用光网中的一个关键问题.文章从经济学的角度出发提出了路由与波长分配问题的一种数学模型,并且进行了分析和仿真.结果表明,模型较大程度地反应了现实,对网络运营商而言很有参考价值.

Routing and wavelength assignment problem is a key problem for WDM optical networks. Pricing of the optical networks will play a key role from network operator's point of view to achieve the maximum profit. In this paper,a stochastic pricing model is proposed and simulation results show a close agreement with real network situations.
