Abstract: Queue processing method and apparatus in a network system are provided. The queue processing method in a network system includes when a packet is input to a buffer, checking whether the buffer belongs to the same memory channel; when the buffer does not belong to the same memory channel, converting an address of a buffer descriptor about the packet to an address of a next packet address storage of the same channel of a queue; and enqueuing the converted address.

Abstract: Disclosed is an authentication method between a mobile node (MN) and a home agent (HA) in a wireless communication system supporting packet communication. The wireless communication system includes the HA, a foreign agent (FA) connected to which the MN assigned a Mobile IP address, and first and second servers provided respectively to the HA and the FA for authentication. Upon receiving a Registration Request message from the MN, the FA generates an Access Request message and transmits the generated Access Request message to the first server through the second server. Upon receiving the Access Request message, the first server generates an authentication shared key with a preset number and transmits the generated authentication shared key to the FA through the second server. The FA authenticates the Registration Request message according to the authentication shared key and transmits the authenticated Registration Request message to the HA.
