NETWORK DEVICE AND METHOD OF TRANSFERRING PACKET OF NETWORK DEVICE

摘要

The present invention relates to a network device. A network device of the present invention comprises: an authentication module composed to manage an authority list; a packet analysis module which extracts a first source address, a first destination address, authentication information, and first data from a first packet; a distinction module which distinguishes addresses according to a type of the first data referring to a lookup table; and a forwarding module which generates a second packet by selecting a destination address as a second source address, the distinguished address as a second destination address, and the first data as second data. The authentication module outputs a valid authentication result when authentication information corresponds to the authority list. The packet analysis module outputs the first data by the distinction module, when the valid authentication result is received.
