Re: [idn] draft about Evaluation of various ACEs with existing Chinese (BIG5) Domain Names
Dear all
Till now I did not see this draft have been announce by IETF IDN WG.
Neither find it on the IETF I-Draft web site.
Would some one please help me to check it?

> 1. Test data and tools
>
> The sample data were come from TWNIC registration database. All of
> them are in BIG5 encoding. The amount of the data is 28454. And the
> data distribution by the length is:
>
> Length of data quantity of BIG5 Domain Names
> 2 chars 3762
> 3 chars 3914
> 4 chars 4613
> 5 chars 1723
> 6 chars 1851
> 7 chars 4282
> 8 chars 1621
> 9 chars 1254
> 10 chars 2075
> 11 chars 1215
> 12 chars 753
> 13 chars 646
> 14 chars 745
>
> amount=28454
>
> TWNIC just accept 2 to 14 BIG5 chars in a Chinese Domain Name. Those
> data are all in local encoding of BIG5 ( or CP950 ). Base on those
> data, apply them to various ACEs. There are RACE-03 [RACE], BRACE-00
> [BRACE], LACE-01 [LACE], UTF-6-00 [UTF6], DUDE-02 [DUDE],
> AMC-ACE-M-00 [AMCACEM], AltDUDE-01 [AltDUDE], AMC-ACE-O-00 [AMCACEO],
> and AMC-ACE-R-01 [AMCACER].
>
> 2. Result of each ACE length
>
> The CHN_len is the length of Chinese (BIG5) domain name in byte
> before apply ACE encoding. All of the data in the same CHN_len, the
> max_len is the maximum length, the min_len is the minimum length,
> the aver_len is the averager length of them after apply ACE encoding.
