| 中文摘要: |
| 研究了IP over WDM网络的低碳路由问题,综合 考虑业务持续时间和利用可再生能源和传统能源供能两个 因素,基于分层图模型,提出一种带有业务持续时间感知的绿色路由(HTAGR)算法。HTAGR 依据节点处太阳能 供能情况以及节点和链路的能耗情况动态调整链路权值,并鼓励选择业务持续时间内需要额 外消耗传统能源最少的 路径建立连接。仿真结果表明,与传统节能路由算法相比,HTAGR 有利于消耗更少的传统能 源和使用更多的可再 生能源,在保持较低阻塞率的同时,进一步降低了业务平均传统能耗和CO2排放量。 |

| In order to reduce energy consumption and the concomitant green house gases (GHG) emission of networks, the issue of routing with lower carbon emission in IP over wavelength division m ultiplexing (WDM) networks is inve stigated in this paper.A hold-time aware green routing (HTAGR) algorithm based on layered graph model is proposed, with an integrated consideration of holding-time of traffic and the hybrid usage of renewable energy and non-renew able energy.The proposed algorithm dynamically adjusts the weights of links according to the solar energy supply of nodes and the energy consumption of nodes and fiber links.And it encourages to choose the path with the least additional traditional energy consumption during the holding-time of traffic.The simulation results show that the HTAGR algorithm ca n not only maintain a low blocking probability,but also reduce traditional energy consumption and carbon emission by encouraging to use more renewable energy,compared with other traditional energy-saving algorithms . |
