Abstract: PURPOSE: An integrated local area network for an IP based integrated service is provided to reduce the cost for network construction and equipments and the cost for operation and maintenance by realizing data, audio and video application services without an extra audio telephone network and a private branch exchange. CONSTITUTION: A basic integrated local area transport network(42) is formed of a plurality of fast switch and data transport systems(41) having a basic data transport functions and a gateway connection function with the existing voice telephone communication network. A programmable switch control server(43) is connected to the basic integrated local area transport network(42). An integrated local area network(LAN) call processing control unit(44) provides integrated control functions of call processing by different protocols to provide audio and video services in an IP based network. A policy based traffic control server(45) is provided to improve the quality of the audio and video services in the IP based network. A network management server(46) provides a simple network management protocol(SNMP) of the LAN based standard network management function.

Abstract: PURPOSE: A forwarding method for VoIP traffic in an IP router and a forwarding method therefor are provided to transmit VoIP call connection information in multicast transmission method, and to supply a QoS(Quality of Service) function while forwarding a VoIP packet by using the transmitted information, thereby reducing system burden. CONSTITUTION: When a packet is received from a line card of a router(710), the router retrieves a destination IP address of an IP header of the received packet from a forwarding table of the line card, and decides whether a next hop to be transmitted exists(720). If so, the router checks whether the received packet is a VoIP packet(730). If so, the router confirms whether an IP precedence field value of a ToS(Type of Service) octet is 5(740). If not, the router sets the value to 5 or changes a DSCP value into 40(750). The router retrieves a precedence value for a corresponding flow from the forwarding table(760), and performs a queuing process(770).

Abstract: PURPOSE: A vehicle performance diagnosis system and a method thereof are provided to allow a user to easily find an error of a vehicle by automatically diagnosing and evaluating the vehicle performance. CONSTITUTION: A vehicle performance diagnosis system includes a diagnosis device(100) for collecting information about an engine and components of a vehicle. The vehicle performance diagnosis system also includes a communication device, which receives a call signal of a user requesting a diagnosis result of the diagnosis device(100) through a communication network and transmits the diagnosis result to the user in real time. The diagnosis device(100) is connected to a computer(300) in order to communication with the user in real time. The diagnosis device(100) includes a remote detecting section(110), a control section(120) and a display section(130).
