根系统稳定性调查研究提案征询

互联网名称与数字地址分配机构("ICANN")现征召一家或多家服务提供商,展开技术调查以审视新通用顶级域项目(以下简称"本项目")对 DNS 根系统所带来的影响。ICANN 为了执行其使命,支持互联网唯一标识符系统的安全和稳定,将审视本项目对 DNS 根系统所带来的影响。入选提供商将设计并执行一项或多项调查,内容涉及:对根服务器运营商的数据、过往绩效数据、过往研究调查数据、其他工具和方案进行搜集和分析。ICANN 现征询一家或多家合格服务提供商以及时有效地展开这项复杂的调查工作。

根据 ICANN 政府咨询委员会的建议 和其他讨论,针对本项目的安全性和稳定性的审核属于组织承诺之一。特别地,ICANN 承诺对新通用顶级域对 DNS 根系统的运营所带来的影响进行审核,且在调查认定 2012 年的域名授权轮次没有损害根系统的安全性或稳定性前,延迟后续域名申请轮次的授权工作。

本次调查研究的目的至少包括以下方面:

  • 针对本项目对 DNS 的安全性和稳定性所带来的影响进行全面审核。
  • 如有必要,考虑在向根区添加更多顶级域前,需要采取哪些准备措施。
  • 如有必要,考虑社群需要采取哪些措施持续评估根区的状态。

如需获取提交回复的其他信息、完整时间表和详细说明,请点击 此处。[ZIP, 983 KB]

请于世界协调时 2015 年 7 月 2 日 23:59 时前将提案提交至:RootStabilityStudy-RFP@icann.org

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as""icann.org"" is not an IDN."
