  3. Protocolo de transporte • UDP – Essencial para aplicações do gênero, devido à velocidade. • RTP (Real-time Transport Protocol) –Implementado pela biblioteca Java Media Framework (JMF). /*funciona usando pacotes UDP para o envio de streams */

  4. Protocolo de aplicação • VCMP - Protocolo próprio de aplicação sobre TCP. • Segue os seguintes estados . . .

  5. FSM - Cliente

  6. FSM – Servidor

  7. Configurando o servidor

  8. Inicializando o Cliente

  9. Chat

  10. Reproduzindo vídeo
