  • Patent number: 8379640
    Abstract: An internetwork device comprises a receiving module, an inter-device packet transfer interface, an inter-device packet transfer controller, an address translation module, and a transmission module. The receiving module receives a packet from a first network. The inter-device packet transfer interface carries out inter-device packet transfer involving transfer of a packet to or from another internetwork device. The inter-device packet transfer controller controls the inter-device packet transfers such that multiple fragmented packets created from a same original packet are collected by the same internetwork device, the fragmented packets being packets created by dividing a single original packet into multiple parts. The address translation module translates between a local address used within a specific network and a global address used across multiple networks, for at least one of a source address and a destination address of a packet.
