Abstract
A method for converting network packets and a circuit system are provided. The circuit system uses firmware therein to record tables for implementing packet conversion between two types of networks (IPv4 and IPv6). In the method, a process of mapping of address and port using encapsulation (MAP-E) or a process of mapping of address and port using translation (MAP-T) is determined according to IPv4 packets routing requirement to embody an uplink and a downlink packet conversion process. A content table stores an IPv6 packet header after the MAP-E or MAP-T process. A control table is referred to for controlling the fields to be updated when adding the IPv6 packet header. A forwarding mapping rule table is referred to for determining to convert a destination IP address of an uplink IPv6 packet, or both a source IP address and a destination IP address of a downlink IPv4 packet.
