Provided are a mobile device capable of generating multiple maximum transfer units (MTUs) and a data transfer method. The method includes determining whether a network is registered with the mobile device; if the network is not registered in the mobile device, generating a virtual interface to generate a maximum transfer unit (MTU) value of the network; and registering the network by storing the MTU value of the network in the mobile device. The mobile device includes an MTU management unit configured to determine whether a network is registered with the mobile device, and, if the network is not registered in the mobile device, to generate a virtual interface to generate an MTU value of the network.

Mobile device to generate multiple maximum transfer units and data transfer method

A method of operating an Internet protocol (IP) address allocates, creates, and processes an interface identifier (ID) of an IP address area. In the allocation, the IP address area includes a subnet prefix area and an Interface ID area, and certain bits of the Interface ID area are used as an index area of a subnet gateway. The allocation is implemented in order from the higher layer to the lower layer so that the Interface ID area is sequentially allocated from the higher bits for the index areas of the respective layers. The combination of the certain bits of the allocated Interface ID and the subnet prefix area of the IP address area is used as the subnet ID of the subnet layers. The lowest subnet gateway allocates the Interface ID to terminating equipment to access the IP network based on a format of the IP address.

Method of operating internet protocol address and subnet system using the same

A method of operating an Internet protocol (IP) address that effectively allocates, creates, and processes an interface identifier (ID) of an IP address area, and a subnet system using the same are provided. Allocation is done such that in the IP address area including a subnet prefix area and an Interface ID area, certain bits of the Interface ID area are used as an index area of a subnet gateway. In this case, the allocation is implemented in order from the higher layer to the lower layer so that the Interface ID area is sequentially allocated from the higher bits thereof for the index areas of the respective layers. The combination of the certain bits of the allocated Interface ID and the subnet prefix area of the IP address area is used as the subnet ID of the respective subnet layers. The lowest subnet gateway allocates the Interface ID to terminating equipment trying to access to the IP network based on a format of the IP address.
