A multi-home agent control apparatus and method are provided. The multi-home agent control apparatus includes a packet observing unit, which observes a packet input to or output from a home link; a home agent list storage unit, which creates a home agent list using home address information included in a binding update (BU) message and stores the home agent list if the packet observing unit receives the BU message and a binding acknowledgement (BACK) message; and a preference value calculation unit, which calculates a preference value of each of the home agents using the home agent list.

A home agent management apparatus and method for routing a packet using a home network equipment as a home agent in a mobile Inter Protocol version 6 (IPv6) are provided. The home agent management apparatus includes a packet analyzer, which receives a packet and analyzes the packet; a database, which stores information indicating whether a home agent of a home network operates normally according to the result of the analysis; and a home agent function executor, which performs a home agent function in place of the home agent when the home agent does not operate normally. Accordingly, a load concentrated on a home agent of an Internet Service Provider (ISP) can be split.
摘要:
A method of advertising an address of a domain name service (DNS) server present, for example, on an IPv6 network by searching a location of the DNS server on a router network subnet using a dynamic routing protocol, storing link state information of the router indicating the DNS server existence in the router subnet, in a link state advertisement of the router, and delivering the link state advertisement to all routers within an autonomous system, to which the router belongs. When the router having the location of the DNS server is requested by another router to provide the DNS server address, the router replies to the requesting router, and the requesting router receiving the reply, advertises a router advertisement message containing the DNS server address to a subnet to which the requesting router belongs. Accordingly, a network can be set without manually setting DNS server addresses at hosts.
摘要:
A system for multicasting multimedia contents using Multicast Listener Discovery protocols according IPv6 standards and a method of reproducing multimedia contents using the same. The method of reproducing multimedia contents includes transmitting a first packet including channel information regarding a channel selected by a user, receiving a second packet including multimedia contents transmitted by multicasting through the selected channel in response to the first packet, and reproducing the multimedia contents included in the received second packet. Multicast packets transmitted to a router in a connection network by multicasting can be transmitted to home multimedia devices, so that congestion of the Internet in the IPv6 environment by an increased amount of data can be prevented.
摘要:
An apparatus and method for enabling communications between heterogeneous terminals are provided. A method for establishing an ad-hoc network includes: accessing a first terminal, on which a first protocol stack is installed; accessing a second terminal, on which a second protocol stack is installed; receiving a data packet, formatted for the first protocol stack, from the first terminal; converting the format of the data packet to the format of the second protocol stack; and transmitting the converted data packet to the second terminal. The apparatus and method enable a plurality of heterogeneous terminals, conventionally unable to communicate directly with each other, to form an ad-hoc network in which they can freely communicate with each other.
摘要:
A method and apparatus for managing power in a portable information device. The method includes entering a low power consumption state if power of the device drops below a first threshold; and backing up data stored in an internal memory of the device through a network if the power of the device drops below a second threshold that is lower than the first threshold.
摘要:
A wireless network apparatus including an authentication information storage unit to store first authentication information for network communication, an authentication information converting unit to generate second authentication information by converting the stored first authentication information according to an predetermined authentication method, a nonvolatile storage unit to store the generated second authentication information, and an authentication processing unit to conduct an authentication based on the second authentication information.
摘要:
A method and apparatus for waking up a remote main system. The method includes: certifying whether a user of a terminal which transmits a packet for waking up a main system that is in a sleeping state is a legitimate user of the main system; and transmitting a wake-up signal to the main system if it is certified that the user is legitimate. Access of uncertified users can be prevented by certifying a user who is in the process of logging on or logging into the main system before the main system wakes up.
