【摘要】：针对现行域名解析系统存在各种性能和安全上的问题(例如,查询延迟、更新延迟、易受DoS攻击等),提出了一种新型的、可增量部署的、和现行DNS兼容的、具有更好性能的域名解析服务模型。此服务模型基于云技术,利用云及其网络架构来发布DNS记录,响应用户的域名解析请求,提供域名解析服务。在此服务模型中,云的节点服务器实现了域名解析器和权威域名服务器的功能,域名的权威DNS记录被发布到各节点服务器,DNS查询结果直接由节点服务器返回给用户(现行的DNS则需要访问多级域名服务器来完成对域名解析器中未缓存的DNS记录的解析)。理论分析和实验证明,此服务模型与现行的各种域名解析服务相比,其DNS查询延迟、更新延迟、故障应变能力、可靠性等各方面性能都有显著提高。
[Abstract]:In view of the problems in the performance and security of the current domain name resolution system (such as query delay, update delay, vulnerability to DoS attacks, etc.), this paper proposes a new type of domain name resolution system, which can be deployed incrementally and compatible with current DNS. Domain name resolution service model with better performance. Based on cloud technology, this service model uses cloud and its network architecture to publish DNS records, respond to users' requests for domain name resolution, and provide domain name resolution services. In this service model, the node server of the cloud implements the functions of domain name parser and authoritative domain name server. The authoritative domain name DNS records are published to each node server and returned to the user directly by the node server. The current DNS needs to access the multi-level domain name server to complete the parsing of the uncached DNS records in the domain name parser. The theoretical analysis and experimental results show that compared with the existing domain name resolution services, the proposed model can significantly improve the performance of DNS query delay, update delay, fault response ability, reliability and so on.
