Title (EN) ADDRESS-SHARING SYSTEM
(FR) SYSTÈME DE PARTAGE D'ADRESSE
(JA) アドレス共有システム
Abstract:
(EN) Packet forwarding between a global network, mutually accessible through use of IP addresses, and other networks is carried out by access routers (100-1 to 100-2), using IP addresses and port numbers. A port resource allocation device (400) manages the port numbers in units of IP addresses, and, at the time of packet forwarding, allocates the port numbers managed by pre-assigned IP addresses to the access routers (100-1 to 100-2). The access routers (100-1 to 100-2) forward the packets, using the IP addresses pre-assigned to the access routers (100-1 to 100-2) and the port numbers that the port resource allocation device (400) allocated.
(FR) La présente invention concerne la retransmission de paquet entre un réseau global, mutuellement accessible par l'utilisation d'adresses IP, et d'autres réseaux qui est effectuée par des routeurs d'accès (100-1 à 100-2), à l'aide d'adresses IP et de numéro de port. Un dispositif d'allocation de ressources de port (400) gère les numéros de port dans des unités d'adresses IP et, au moment du transfert du paquet, alloue les numéros de port gérés par des adresses IP pré-attribuées aux routeurs d'accès (100-1 à 100-2). Les routeurs d'accès (100-1 à 100-2) retransmettent les paquets, à l'aide des adresses IP pré-attribuées aux routeurs d'accès (100-1 à 100-2) et les numéros de port que le dispositif d'allocation de ressources de port (400) a alloués.
(JA) IPアドレスを用いて相互に到達可能なグローバル網と、それ以外の網との間のパケット転送を、アクセスルータ(100-1~100-2)がIPアドレスおよびポート番号を用いて行い、ポート資源割り当て装置(400)が、IPアドレス単位にポート番号を管理し、当該パケット転送をする際、アクセスルータ(100-1~100-2)にあらかじめ付与されたIPアドレスで管理されているポート番号を割り当て、アクセスルータ(100-1~100-2)が、アクセスルータ(100-1~100-2)にあらかじめ付与されたIPアドレスと、ポート資源割り当て装置(400)が割り当てたポート番号とを用いて、パケット転送を行う。
