Packet transfer apparatus

摘要

A packet transfer apparatus connects two networks of different protocols. The packet transfer apparatus, connected to a first communication network and a second communication network, performs the steps of: storing first destination correspondence information; receiving a packet of the first communication protocol; based on the first destination correspondence information, determining destination information of a packet of the second communication protocol corresponding to destination information of the received packet of the first communication protocol; generating the header of the packet of the second communication protocol, based on the determined destination information of the packet of the second communication protocol; converting the received one or more packets of the first communication protocol into one or more packets of the third communication protocol; and adding the generated header of the packet of the second communication protocol to the packets of the third communication protocol.

主权项

1. A packet transfer system comprising:
a first packet transfer apparatus in a first network operated with a first communication protocol; and a second packet transfer apparatus in the first network operated with the first communication protocol, wherein the first packet transfer apparatus comprises: a first interface that
receives a second communication protocol packet from a second network operated with a second communication protocol, the second communication protocol packet being generated by a third communication protocol packet,converts the second communication protocol packet into the third communication protocol packet with terminating the second communication protocol, andconverts the third communication protocol packet with terminating the second communication protocol into a first communication protocol packet by adding a header of the first communication protocol packet, and a second interface that sends the first communication protocol packet into the first network, and wherein the second packet transfer apparatus comprises: a third interface that receives the first communication protocol packet from the first network, and a fourth interface that
converts the first communication protocol packet into the third communication protocol packet, andsends the third communication protocol packet to a third network.
