Abstract
(EN)
A method, a communication system and a device for ARP packet processing are provided. The method includes that: the ARP packet is received and the type of the ARP packet is judged; if the ARP packet is a ARP request packet and the item corresponding to the ARP request packet is found in the locally configured ARP list, then the response corresponding to the ARP request packet is sent; if the ARP packet is a ARP response packet and the item corresponding to the ARP response packet is found in the locally configured ARP list and the reporting parameter in the item is allowing the reporting, then the ARP response packet is reported; if the itemcorresponding to the ARP response packet is not found in the ARP list, then the ARP response packet is discarded.

La présente invention concerne un procédé, un système de communication et un dispositif pour le traitement de paquets ARP. Le procédé comprend les étapes suivantes : le paquet ARP est reçu et son type est évalué. Si le paquet ARP est un paquet de requêtes ARP et que l'élément correspondant au paquet de requêtes ARP est trouvé dans la liste ARP configurée localement, la réponse correspondant au paquet de requête ARP est envoyée. Si le paquet ARP est un paquet de réponse ARP et que l'élément correspondant au paquet de réponses ARP est trouvé dans la liste ARP configurée localement et que le paramètre de rapport dans l'élément autorise le rapport, le paquet de réponses ARP est rapporté. Si l'élément correspondant au paquet de réponses ARP n'est pas trouvé dans la liste ARP, le paquet de réponses ARP est rejeté.
