mDNS Development Plan TWNIC May 2000

What is the Problem Problem #1 –Existing Internet doesn't deliver multilingual name resolution –S1 : Developing multilingual DNS (mDNS) Problem #2 –There is no multilingual registry in gTLD, ccTLD –S2 : Coordinate Model : redirect multilingual inquiry to mDNS, otherwise forward ASCII name (RFC1035) inquiry to existing DNS Problem #3 –Multilingual system interoperability –S3 : mDNS Roaming Network

mDNS Topology

mDNS Virtual Root 分配 每一個國家 / 地區擁有自己字碼的 Pseudo Root Server 共同維護及交換每一個 Root Server 之 root cache table Root Cache Table 之內容 : 1. 每一個國家 / 地區與有一個 ccTLD 與最常用之 Local Encoding 2. 每一個國家 / 地區與有一個 mgTLD 與最常用之 Local Encoding 3.ccTLD 及 mgTLD 另有 UTF-8 之 Global Encoding mDNS Server 皆能支援各國 Local Encoding 及 Global Encoding

Windows Client & Server 之轉碼

TWNIC C-DNS Task Force Chinese Domain Name Technical Task Force Chair: Prof. Lee-Ming Tseng (NCU) Prof. Jin-Ming Ho (Sinica) Activity Technical research and support to mDNS implementation/promotion Provide mDNS solutions and testing Cooperation among ccTLD Draft standard-related documentations

mDNS 發展目標 不需下載 client 程式 容易轉換現有 DNS 至 mDNS Root Cache Table 維護機制 兼顧 Local Encoding 及 Global Encoding 不用 Zero Level Domain (ZLD) 不須與英文 Domain Name 有相依性 Application/resolver ( 含 proxy 、 send mail) 皆須支援 8-bit clean 聯合撰寫技術文件提交 IETF
