  2. Overview • EPP Introduction • What is EPP • Why EPP • EPP relate information • TWNIC EPP Implementation • TWNIC EPP Environment • EPP issue • Policy issue • TWNIC technical issue

  3. What is EPP • Client-Server Protocol for provisioning and management objects • Key feature • Object model • XML Based • Extensible framework • Generic object management operation

  4. EPP Command • Session Management Commands • Login: login to EPP server • Logout: logout from EPP server • Query Commands • Check: retrieve object availability • Info: retrieve information about an object • Transfer: retrieve status of a transfer operation • Poll: retrieve queued messages at server • Object Transform Commands • Create: create an instance of an object • Delete: delete an instance of an object • Renew: extend the validity of an object • Transfer: initiated a change in the sponsorship of an object • Update: change information associated with an object
