METHOD AND DEVICE FOR TRANSLATION BETWEEN IPV4 AND IPV6

摘要

Disclosed is a method for translation between IPv4 and IPv6. A BIH link tracker and a quick translator are provided within a network core. When a link between an IPv4 client and an IPv6 server is established, a data packet sent by the IPv4 client to the IPv6 server is sent to the server after being translated by a standard translator. The BIH link tracker extracts and records link information and translation information of the IPv4 client and the IPv6 server from within the data packet exchanged by both sides. After establishment of the link between the IPv4 client and the IPv6 server is complete, during sending of a data packet, the data packet is sent to the quick translator. The data packet is translated by the quick translator according to the translation information corresponding to the link information recorded by the BIH tracker, then sent. Also disclosed is a device for translation between IPv4 and IPv6.
