摘要：

【目的】 针对基于区块链的域名系统中域名状态信息广播传播存在长传输路径、重复转发等问题，设计一种地理感知的低时延、低冗余的高效广播方法。【背景】 基于区块链的域名系统通过将域名状态信息写入区块链以实现鲁棒、可信的域名服务，然而相关信息在区块链底层P2P网络的低效传输严重影响了系统性能。【方法】 针对基于区块链的域名系统，本文提出一种面向域名状态信息的高效广播方法。首先，在节点编码中融入地理信息；其次，基于节点编码所反映的邻近性对节点进行区域划分；最后，在区域间和区域内对域名状态信息进行并行传输。【结果】 实验结果表明，与多种传统方法相比，本方案具有较低传输延迟和传输冗余。

Abstract:

[Objective] To address the issues of long transmission paths and repeated forwarding in the broadcast propagation of domain name state information in blockchain-based DNS systems, this paper designs a low-latency, low-redundancy broadcast propagation mechanism. [Background] Blockchain-based DNS systems record domain name state information into the blockchain to achieve robust and trustworthy domain name services. However, inefficient broadcast propagation of domain-related information over the underlying P2P network severely affects system performance [Method] This paper proposes an efficient geo aware broadcast transmission method for blockchain-based DNS systems. First, geographic information is incorporated into node encoding. Next, nodes are partitioned into regions based on the proximity reflected by their encodings. Finally, domain name state information is transmitted in parallel both between regions and within regions. [Results] Experimental results show that, compared with various traditional methods, the proposed scheme achieves lower transmission latency and reduced transmission redundancy.
