    摘要: Managing a Transmission Control Protocol (TCP) connection established between two applications includes providing a TCP/IP (Internet Protocol) kernel adapted to: store establishment information of the TCP connection and an established value for a TCP session connectivity check with respect to the TCP connection; create a Session Connectivity Check (SCC) message according to the establishment information and established value; transmit the SCC message to a TCP/IP kernel of another party, and determine whether or not the TCP connection is operating normally according to whether an SCC response message has been received from the TCP/IP kernel of the another party.

    摘要: Managing network information in Access Routers(ARs) includes: communicating with neighboring Access Routers (ARs) to obtain information of each of the ARs and Access Points (APs) belonging to a subnet of a relevant AR; storing the information of the ARs and APs in a database; and performing a communication network service in accordance with the information stored in the database. Desired information can be shared without a need for adding any separate element to the network architecture. In addition, because a Candidate Access Router (CAR) table is generated during the operation of the Open Shortest Path First (OSPF), the AR immediately responds to the information requested by a mobile node so as not to increase a handoff delay and so as to reduce a burden of the mobile node.

    摘要: The apparatus and method for monitoring the software module state of the embedded multitasking operating system in a system using the embedded multitasking operating system according to the invention sequentially records the state information of the software modules in the state recording range of the hardware logic, sequentially reads the state information of the software modules from the state recording range, and displays the state information so that the user can easily recognize the same. As a result, the state information of the software modules can be monitored and inspected independent from the operation of the software modules of the operating system, and thus the state of the software modules or the operating system can be inspected in any exceptional software-associated situations.

    摘要: A system and method for a Trivial File Transfer Protocol (TFTP) includes a broadcasting function in which a new option is added to the TFTP to allow several clients to connect with one server to simultaneously download files. The method includes a first step of transmitting, by a first client, an extended read request message to request broadcasting file transmission to a server; a second step of transmitting, by the server, an option acknowledgement message notifying that the first client is a master client to the first client; a third step of transmitting, by a second client, the extended read request message to request broadcasting file transmission to the server; a fourth step of transmitting, by the server, the option acknowledgement message notifying that the second client is not a master client to the second client; a fifth step of broadcasting, by the server, data and then waiting to receive an acknowledgement message from the first client; and a sixth step of effecting, by the server, repetition from the fifth step until the server transmits all remaining data when the server receives the acknowledgement message from the first client.
