Abstract
(EN)
This on-vehicle communication device is provided with: a storage unit that stores correspondence information indicating correspondence relation between an address and a port number; and a communication unit that filters a received packet by using the correspondence information in the storage unit, wherein a subject port number which is a port number of a subject device has been stored in the correspondence information in advance, the communication unit selectively passes the packet including the subject port number during the filtering, and the communication unit carries out an address registration process for acquiring the address from the packet including the subject port number and registering the acquired address in the correspondence information in association with the subject port number, and selectively passes the received packet including the subject port number and the address during the filtering after the address registration process.

L'invention concerne un dispositif de communication embarqué qui comprend : une unité de stockage qui stocke des informations de correspondance indiquant une relation de correspondance entre une adresse et un numéro de port ; et une unité de communication qui filtre un paquet reçu à l'aide des informations de correspondance dans l'unité de stockage, un numéro de port sujet qui est un numéro de port d'un dispositif sujet ayant été stocké dans les informations de correspondance à l'avance, l'unité de communication transmet de manière sélective le paquet comprenant le numéro de port de sujet pendant le filtrage, et l'unité de communication réalise un processus d'enregistrement d'adresse pour acquérir l'adresse à partir du paquet comprenant le numéro de port de sujet et enregistrer l'adresse acquise dans les informations de correspondance en association avec le numéro de port de sujet, et transmet de manière sélective le paquet reçu comprenant le numéro de port de sujet et l'adresse pendant le filtrage après le processus d'enregistrement d'adresse.
