摘要:
A method and apparatus for processing a plurality of data in a protocol module. The method includes (a) determining priorities of the plurality of data based on information on the plurality of data, and (b) driving a plurality of protocol modules, which process the plurality of data according to a predetermined protocol, based on the priorities determined in (a). Accordingly, it is possible to process the plurality of data at a high rate by constructing a plurality of Internet protocol (IP) layers and a plurality of a transmission control protocol/user datagram protocol (TCP/UDP) layers in a hardware manner without involvement of a processor.

A method for more efficiently operating a network, and more particularly, for discovery of a path maximum transmission unit (PMTU) between nodes on an IP network, is provided. The method includes (a) comparing the size of a received packet with a maximum transmission unit (MTU) of a next link; and (b) if the size of the received packet is greater than the MTU of the next link, generating an error message, transmitting the generated error message to a source node, generating a test message of the size of the MTU of the next link, and transmitting the generated test message to a destination node. According to the PMTU discovery method, a PMTU can be determined in a shorter time, and it is possible to minimize the use of network resources.

There are provided an apparatus and method for automatically configuring virtual addresses for a duplicate address when the duplicate address is detected in a single subnet. The apparatus in a non-configured node includes a duplicate address search message transmitter, a duplicate address response message receiver, a virtual address allocation message transmitter, and a virtual address response message receiver. The apparatus in a configured node includes a duplicate address search message receiver, a duplicate address response message transmitter, and a virtual address response message receiver. The apparatus in a router includes a virtual address allocation message receiver, a virtual address allocator, and a virtual address response message transmitter.

An Internet control message protocol packet generating system includes a field error detecting unit, which detects at least one field error upon reviewing all fields of the Internet protocol packet; and an Internet control message protocol packet generating unit, which records information for the at least one detected field error on the Internet control message protocol packet. The Internet control message protocol packet generating system may further include a field error information storing unit, which sequentially stores information on field errors detected by the field error detecting unit. The Internet control message protocol packet generating unit may generate the Internet control message protocol packet based on field error information stored in the field error information storing unit.

摘要:
A method and system to provide a blog by using a mobile terminal, and a mobile blog (MB) caster therefor, the method including: receiving blog data including one or more pieces of downsized data from an MB caster; selecting a piece of downsized data from among the one or more pieces of downsized data; obtaining metadata corresponding to the selected piece of downsized data; accessing a web blog server; and downloading original data corresponding to the metadata from the web blog server. Since the blog is created and provided by using the downsized data, instead of the original data, a blog server operation can be realized by using only existing mobile devices. Furthermore, the mobile terminal does not have to be connected to the Internet (or the web blog server) for a blog service. Also, it is possible to provide the blog at very high speed.

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.

An apparatus and method for authorizing a gateway are provided. The apparatus includes a gateway function determiner, which determines whether a gateway on a predetermined network performs a particular function for a predetermined node based on a network database including information on each node managed by the gateway and information indicating a function performed by the gateway for the node; and a gateway authorizer, which authorizes the gateway to perform the particular function for the predetermined node when the gateway function determiner determines that the gateway performs the particular function for the predetermined node.
