Definitions

  • the method and the device for routing the exit provided by the present invention, when the route is formed, the switch determines whether the converted Layer 2 port is a smartgroup, and if it is determined to be a smartgroup, the member port information of the obtained smartgroup is sorted to obtain a member port. Array; select a member port as the exit of the route in the member port array according to the routing information obtained by the search, and write the selected member port information to the forwarding chip.
  • the routing exit selection process of the present invention can be completed by a software module disposed inside the switch, and is not executed in the forwarding chip, thereby reducing the complexity of the forwarding chip and reducing the cost of the forwarding chip, because there is no cost limitation.
  • the forwarding chip can be applied to all routing-related services.
  • the destination addresses are 224.1.1.1 and 224.1.1.2, respectively, and the corresponding 32-bit unsigned integers are OxEOOlOlOl and 0XE0010102, respectively, and the smartport member port array includes two member ports. They are: 1/2 port corresponding to sequence number 0 and 2/1 port corresponding to sequence number 1, then,
  • Step 202 Reorder all member ports in the changed smart group to obtain an array of member ports.
  • the selecting module is configured to search routing information, and sorting according to routing information in a sorting module In the resulting member port array, select a member port as the exit of the route.

Abstract

La présente invention porte sur un procédé de sélection de sortie de route qui comprend les étapes suivantes : lorsqu'une route est formée, un commutateur détermine si un port de couche 2 obtenu par transformation est un port d'agrégation de liaisons, c'est-à-dire un smartgroup, et s'il est déterminé qu'il est un smartgroup, les informations obtenues des ports membres du smartgroup sont séquencées de façon à obtenir une matrice de ports membres; un port membre est sélectionné dans la matrice de ports membres en tant que sortie de route selon les informations de route obtenues par une recherche. Par ailleurs, la présente invention porte également sur un appareil de sélection de sortie de route. Le procédé et l'appareil décrits dans la présente invention peuvent être appliqués à tous les services liés à des routes et peuvent améliorer l'efficacité de transfert de trafic de données.
