在DNS区域委派中,被委派域的NS资源记录同时出现在父区域和子区域中,这使得域名解析过程变得复杂,尤其是服务器选择。在本文中,我们研究了委托域的递归解析机制和必要的操作。由于目前还没有关于这种解析的规范,我们提出了一些建议,如NS记录替换机制。此外,当NS记录同时从父区域和子区域获得时,我们分析了委托对服务器选择的影响。我们提出了一种集成的服务器选择过程来处理LAME委托,提高了服务器选择的效率。它利用了两个阶段的服务器探测信息,可以帮助节省服务器选择算法中的初始服务器探测。并对NS资源记录的处理和服务器RTT信息的维护提出了几点建议。
In DNS zone delegation, the NS resource records of the delegated domain appear in both the parent and child zones, which complicates the domain name resolution procedure especially for server selection. In this paper, we investigate the recursive resolution mechanism for the delegated domain and the necessary operations. As there are no specifications for such resolution, we provide some recommendations such as NS record substitution mechanism. Furthermore, we analyze the delegation impacts on server selection as the NS records are obtained from both parent and child zone. We propose an integrated sever selection procedure to handle the lame delegation and enhance server selection efficiency. It makes use of th e two stages of server probing information and can help save the initial server probing in the server selection algorithm. Several proposa ls as to the disposal of NS resource records and the maintenance of the rtt information of servers are also presented.
