Provided is a method of operating a tunnel point that provides a tunnel between a router group including at least one router and a mobile node. The method includes: providing a tunnel between the mobile node and the router group by authenticating the mobile node; receiving a packet including an identifier (ID) of a target node from the mobile node; converting the ID of the target node in the packet into a locator corresponding to the ID of the target node; transmitting a packet including the converted locator to the router group; and maintaining the ID of the mobile node by authenticating the mobile node through the router group when the mobile node is connected to another external terminal node.

Provided is a mobile IPv6 fast handovers method, which includes the steps of: a) if a mobile node is moved in a layer 2, receiving a modified RS message from a mobile node in the access router, b) detecting movement of the mobile node in a layer 3 in the access router, c) if the mobile node makes a movement in the layer 3, generating CoA of the mobile node in the access router; d) performing Duplicate Address Detection in the access router to inspect uniqueness of the generated CoA; and e) transmitting a modified RA message to the mobile node in the access router. The Fast Handovers method of the present research performs fast movement detection by using layer 2 information simply and efficiently for fast handover in the mobile IPv6 and generates CoA in the access router instead of the mobile node without operations of many additional messages.

Provided is a computing system and method that utilizes a non-volatile random access memory (NVRAM). A system including the NVRAM as a part of a memory or a whole memory may execute a program in the NVRAM, and, when the system is re-operated after being shut down, may restore a state and data of the program being executed in the NVRAM to an original state and thus, may provide a permanent computing environment.
