Exemples

L’exemple de code suivant affiche des statistiques de réassemblage pour les paquets IP.

   Console::WriteLine( "  Reassembly Data:" );

Remarques

Les paquets qui dépassent la taille maximale pour le transport IP sont divisés en fragments et remontés à la destination. Si certains fragments sont perdus ou n’arrivent pas dans un délai défini, le réassemblage n’aboutit pas.
