1 -4 INTERNET STANDARDS An Internet standard is a thoroughly tested specification that is useful to and adhered to by those who work with the Internet. It is a formalized regulation that must be followed. There is a strict procedure by which a specification attains Internet standard status. A specification begins as an Internet draft. An Internet draft is a working document with no official status and a six-month lifetime. Http: //netwk. hannam. ac. kr HANNAM UNIVERSITY 47
