+Ahora el router H132 debe fragmentar para poder enviarlos por la red FDDI.

+
+Ahora el router H131 toma estos nuevos frames y debe volver a fragmentarlos
+ para poder enviarlos por PPP (que como dijimos tiene un MTU de 1500).
+ Cada fragmento de 4300 bytes de payload se convierte en 3 fragmentos; el

+
+A partir de ahora, no es necesario fragmentar más a estos frames, ya que
+ todos los MTU utilizados en el resto de la transmisión son mayores que
+ el del enlace PPP.
+ Por lo tanto sólo resta que el host reensamble los frames.

+FTP
+\layout Standard
+
+El análisis de tráfico FTP va a ser muy similar al HTTP, con la diferencia
+ de que probablemente los comandos FTP sean tan pequeños que no sufran fragmenta
+ción alguna, mientras que la transferencia de datos sí.
+\layout Subsubsection
+
+Telnet
+\layout Standard
+
+Telnet va a comportarse de manera muy similar a los comandos FTP, ya que
+ son paquetes muy pequeños, seguramente nunca van a ser necesario fragmentarlos.
