CA 2600760

A network and associated methods and apparatus are described. The network includes a wireless access node which is operable to receive first packets from a plurality of wireless computing devices attempting to access the network. Each of the first packets corresponds to one of a plurality of traffic types. At least one of the traffic types corresponds to an encrypted wireless protocol. The wireless access node is configured to associate one of a plurality of identifiers with each of the first packets. Each of the plurality of identifiers corresponds to one of the plurality of traffic types. The wireless access node is further configured to transmit all first packets received from the wireless computing devices to a gateway on the network regardless of destination addresses associated with the first packets. The gateway is operable to determine that a particular one of the first packets from a first one of the wireless computing devices is directed to a second computing device on the network. The gateway is further operable to prevent the particular first packet from reaching the second computing device in response to determining that the particular first packet is directed to the second computing device.

L'invention concerne un réseau et des procédés et un dispositif associés. Le réseau comprend un noeud d'accès sans fil permettant de recevoir des premiers paquets provenant d'une pluralité de dispositifs d'ordinateur sans fil essayant d'accéder au réseau. Chacun des premiers paquets correspond à un type de trafic d'une pluralité de types de trafic. Au moins un des types de trafic correspond à un protocole sans fil chiffré. Le noeud d'accès sans fil est configuré pour associer à chacun des premiers paquets un identificateur d'une pluralité d'identificateurs. Chacun de la pluralité des identificateurs correspond à un des types de trafic. Le noeud d'accès sans fil est en outre configuré pour transmettre à une passerelle du réseau tous les premiers paquets reçus des dispositifs d'ordinateur sans fil, quelles que soient les adresses de destination associées aux premiers paquets. La passerelle permet de déterminer qu'un premier paquet particulier provenant d'un premier dispositif d'ordinateur sans fil est dirigé vers un deuxième dispositif d'ordinateur sans fil du réseau. La passerelle permet en outre d'empêcher que le premier paquet particulier atteigne le deuxième dispositif d'ordinateur s'il est déterminé que le premier paquet particulier est dirigé vers le deuxième dispositif d'ordinateur.
