摘　　要：随着海洋观测手段的增多和覆盖面的扩大,海洋观测系统中包含越来越多的远岛观测数据。由于远离大陆,远岛观测数据传输是海洋观测系统建设面临的难题之一。目前远岛观测数据传输主要依赖于卫星通信技术,存在服务时延高、数据容量大、通信费用高和接入异构系统多等问题。针对上述问题,文章在远岛观测数据传输网络中引入基于边缘计算的移动边缘计算(MEC)-软件定义网络(SDN)架构;利用MEC技术智能选择在本地服务器或MEC服务器上执行计算任务,并迁移数据流量,提高数据的传送和分发能力,能够显著提高无线网络的服务效率;通过加入SDN控制器,使多种网络协议和标准在同一网络架构下得到整合,网络资源得以动态灵活调度和分配,以达到整体优化远岛观测数据传输网络的效果,从而为海洋观测工作提供高效的数据支持。With more and more marine observation methods included,agrowing number of distant island observation data are contained in the marine observation system.Due to the long distance from the mainland,the transmission of distant island observation data is facing some difficult problems.At present,the transmission of distant island observation data mainly depends on the wireless communication technology,with the problems of high service delay,large data capacity,high communication cost,a lot of heterogeneous systems and so on.In order to solve above problems,this paper introduced a Mobile Edge Computing(MEC)-Software Defined Network(SDN)architecture based on edge computing for the distant island observation data transmission network.By using MEC technology,it could intelligently choose to perform computing tasks on local servers or MEC servers,and migrated data traffic to improve the ability of data transmission and distribution,which could significantly improve the service efficiency of wireless networks.For more,by adding SDN controller,a variety of network protocols and standards could be integrated under the same network architecture,and network resources could be dynamically and flexibly dispatched and allocated,so as to optimize the overall distant island observation data transmission network,and then to provide the efficient data support for the ocean observation work.
