摘要
卫星网络具有覆盖全球的通信能力,因此受到越来越多的关注。半透明光学有效载荷可实现 IP-over-WDM 卫星光网络(SON),在提供 IP 路由灵活性的同时,还能实现极大的带宽容量。可充电电池是日食区卫星的唯一能源支持。无节制放电会加速电池老化,缩短卫星运行周期,造成极高的支出成本。卫星移动会造成定时能源供应和流量波动,使 IP-over-WDM SON 的能耗问题更加复杂。本文从电池寿命消耗(BLC)的角度研究了 IP-over-WDM SON 中的绿色流量疏导(GTG)。通过将电池信息和时间信息作为先验知识,提出了电池感知 GTG(BA-GTG)和时间感知 GTG(TA-GTG)。数值结果表明,BA-GTG 和 TA-GTG,尤其是后者,能有效降低 BLC。此外,在性能比较中还设置了多种链路配置,以评估 IP-over-WDM SON 中物理损伤对电池效率的影响。
Green traffic grooming in IP-over-WDM satellite optical networks
With the ability to provide worldwide communication coverage, satellite networks are drawing greater attention. The translucent optical payload enables the implementation of IP-over-WDM satellite optical networks (SONs), which can achieve great bandwidth capacity while providing the flexibility of IP routing. The rechargeable battery is the sole energy support for satellites in the eclipse region. Unrestrained discharge will accelerate battery aging and shorten the satellite operation period, causing extremely high expenditure costs. Satellite movement causes time-scheduled energy supply and traffic fluctuation, complicating the problem of energy consumption in IP-over-WDM SONs. This paper studies green traffic grooming (GTG) in IP-over-WDM SONs from the perspective of battery lifetime consumption (BLC). A grooming graph is designed to implement GTG with the physical impairment constraint in IP-over-WDM SONs, and battery-aware GTG (BA-GTG) and time-aware GTG (TA-GTG) are proposed by taking battery information and time information as prior knowledge. Numerical results indicate that BA-GTG and TA-GTG, especially the latter, can effectively reduce BLC. In addition, multiple link configurations are set in performance comparison to evaluate the effect of the physical impairment on battery efficiency in IP-over-WDM SONs.
期刊介绍:
The scope of the Journal includes advances in the state-of-the-art of optical networking science, technology, and engineering. Both theoretical contributions (including new techniques, concepts, analyses, and economic studies) and practical contributions (including optical networking experiments, prototypes, and new applications) are encouraged. Subareas of interest include the architecture and design of optical networks, optical network survivability and security, software-defined optical networking, elastic optical networks, data and control plane advances, network management related innovation, and optical access networks. Enabling technologies and their applications are suitable topics only if the results are shown to directly impact optical networking beyond simple point-to-point networks.
