在IP over WDM网络中, 光层可以通过建立新的光路来为IP层提供带宽。如何利用光层有限的资源使网络服务提供商的利润最大化是流量疏导的一个重要目标。文章基于迭加网络模型, 研究IP/MPLS over WDM网络的准入机制, 设计算法在不影响整体效率的前提下为网络提供区分服务。

In IP over WDM networks, the optical network can dynamically provide the IP network with bandwidths by setting up a new lightpath. It is an important goal for traffic grooming to maximize the profit of the service provider by utilizing the limited resources of the optical network. In this work, on the basis of the overlay network model, we study the access mechanism for the IP/MPLS over WDM networks and try to develop an algorithm that can provide differentiated services to them without impacting the overall network efficiency.
