DATA MESSAGE PROCESSING METHOD AND SYSTEM, MESSAGE FORWARDING DEVICE

摘要

The present invention provides a data message processing method and system, and a message forwarding device. In an embodiment of the present invention, an IPv6 flow table supporting an IPv6 message is defined in advance in a controller of OpenFlow system architecture, and the IPv6 flow table is delivered to a message forwarding device of OpenFlow system architecture. The message forwarding device, after receiving the data message, determines whether the data message is an IPv6 message according to a link layer data type field comprised in the data message, and if the data message is the IPv6 message, the message forwarding device matches field content comprised in the IPv6 message with field content in the stored IPv6 flow table, and performs a processing on the IPv6 message according to a matching result. Therefore, the embodiment of the present invention enables the message forwarding device of OpenFlow system architecture to support the IPv6 message, thereby extending the OpenFlow system architecture.
