摘要
在WDM光网络中业务流量疏导能够有效地降低网络建设成本。为了疏导网络中的动态业务,提出动态业务流量的可重构疏导方案,并给出相应快速在线算法。此算法通过动态调整网络的虚拟拓扑结构,可使网络适应各种动态业务。计算机模拟结果表明,该算法能得到较优的疏导结果。
Traffic grooming in WDM optical networks can efficiently reduce the cost of network construction. In order to groom the dynamic traffic in optical networks, a reconfigurable grooming scheme of dynamic traffic is developed, and a corresponding fast on-line algorithm is also proposed. The algorithm can make the network to fit all kinds of dynamic traffic through dynamically adjusting the virtual topology of the network. The computer simulation results show that our algorithm can obtain good grooming results.
