Abstract

In the current Internet era, whether the domain name system (DNS) can achieve efficient resolution is of great significance for optimizing user experience and promoting global development. However, the existing DNS architectures have flaws in dealing with network service latency and ensuring their own robustness. Based on this, this study constructs a blockchain-based distributed domain master architecture, aiming to optimize the resolution effect of top-level domains (TLDs). As internet service latency continues to pose severe challenges to user experience and global development, the demand for accelerated DNS resolution always exists. Although local caching has always been helpful in improving DNS efficiency, how to ensure the integrity of cached records is a tricky problem. The new architecture proposed in this study adopts a consortium blockchain framework, allowing nodes to freely enter and exit. Consensus is reached through the 3R-PBFT algorithm, strengthening system security. Focusing on the top-level domains of.com and.net, an in-depth exploration is conducted on the effect of locally deployed caches on resolution time, highlighting the key value of TLD caches in enhancing the DNS resolution speed. Experimental results show that the local cache implemented through the consortium blockchain architecture can not only improve the security of the cache but also reduce the latency of DNS resolution.

面向顶级域名解析优化的区块链增强分布式缓存管理
在当前互联网时代,域名系统(DNS)能否实现高效解析,对于优化用户体验、促进全球发展具有重要意义。然而,现有的DNS架构在处理网络服务延迟和保证自身鲁棒性方面存在缺陷。基于此,本研究构建了基于区块链的分布式域主架构,旨在优化顶级域的解析效果。随着互联网服务延迟不断给用户体验和全球发展带来严峻挑战,对DNS加速解析的需求一直存在。尽管本地缓存一直有助于提高DNS效率,但如何确保缓存记录的完整性是一个棘手的问题。本研究提出的新架构采用联合体区块链框架,允许节点自由进出。通过3R-PBFT算法达成共识,增强系统安全性。以“。com”和“。net”顶级域名为例,深入探讨了本地部署缓存对解析时间的影响,突出了TLD缓存在提高DNS解析速度方面的关键价值。实验结果表明,通过财团区块链架构实现的本地缓存不仅可以提高缓存的安全性,还可以降低DNS解析的延迟。
