基于“白色空间”的备份网络不间断通信研究

Research of Connection Continuity of White Space Backup Network

摘要: 提出了一种基于广播电视频段的“白色空间”备份网络，它提供更具有可靠性的接入网，比传统的接入网更具优势。仿真实验结果证明相比于传统方案，提出的“白色空间”备份网络，更有助于减小报文传输和交换的时延，对于网络中的对时延敏感的大流量数据交换业务意义重大。在互联网或WAN中断的情况下，“白色空间”备份网络能够有利于大流量数据交换业务的快速处理。

Abstract:  This paper proposes the white space backup network that operates on TV spectrum to provide a better reliability access network than conventional unlicensed-based access networks. The numerical results of performance evaluation demonstrate that the proposed white space backup network can contribute to less time delay in the delivery of messages or transactions than the time delay of the conventional approach, and this is a crucial benefit to time-critical applications such as heavy traffic. We expect that the deployment of the white space backup networks can assist those heavy traffic applications to achieve a shorter processing time even under a broken Internet or WAN connection.
