La transición a la nueva versión del protocolo está siendo un proceso gradual en el que tienen que convivir ambos tipos de redes y aplicaciones. Actualmente, millones de aplicaciones IPv4 están repartidas por toda Internet y no pueden comunicarse directamente con aplicaciones desarrolladas para IPv6. En este artículo se presentarán los problemas de interoperabilidad de aplicaciones IPv4 e IPv6 y se estudiarán soluciones aplicables en los nodos extremos de la comunicación, donde normalmente tenemos acceso a la configuración de la máquina/nodo. Como caso de estudio se analizará la implantación de un mecanismo de transición que hemos desarrollado basándonos en una propuesta experimental de Internet Engineering Task Force (IETF).

This paper describes guidelines to help the porting of applications to the new protocol IPv6, especially during the transition period. ISABEL collaborative application is used to exemp lify the porting methodology. ISABEL has been used to support meetings and workshops in which both IPv4 and IPv6 nodes collaborate simultaneously.

As ISABEL uses TCP-UDP/IP to interconnect different network technologies and no QoS control exists, a QoS adaptation function has been added: the ISABEL flow server. This approach has been successfully used in large scale

However, our network programming interfaces remain similar to those used when there was at most one network interface.
