1 mDNS Development Plan TWNIC 20-21 May 2000

2 What is the Problem Problem #1 Problem #2 Problem #3
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

3 DNS Coordinate Architecture
Root Table Root Table mDNS Country Root mDNS Country Root Root System ASCII DNS Multilingual Infra Multilingual Infra ASCII Infra Local mDNS Local mDNS Local mDNS

4 mDNS Roaming Network mDNS Root Table mDNS Roaming Network ASCII Infra

5 mDNS Topology 在每一個國家註冊時該國家必須幫其建立其他字碼的Table

6 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

7 Windows Client & Server 之轉碼

8 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

9 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
