Flash ActionScript 3 API for Mikrotik RouterOS

O MikroTik, além de configuração de Apoio sobre Telnet / SSH / telnet-MAC. possui um chamado RouterOS API.

Através da API que você puder ler informações, configuração definidas e até mesmo eventos. Por exemplo, a lista a todos os usuários conectados dBm WLAN.

A API é “literatura aberta” e você está convidado a criar diferentes idiomas e bibliotecas para postar em seu site. Eles já têm PHP, Ruby, Perl, Java, implementações, etc, objetivo que eu queria ser capaz de criar um aplicativo do AIR do Flash para exibir e configurar roteadores. Então, eu criei um Flash ActionScript 3 classe para isso.

Abaixo uma classe ActionScript para acesso a API do MikroTik:
