Abstract:
PURPOSE: A gateway of a GMPLS(Generalized Multi-Protocol Label Switching) non-support network and operation method thereof are provided to reduce network upgrade costs by including a resource reservation protocol signaling unit. CONSTITUTION: A boundary route protocol routing unit(730) exchanges routing information between a first GMPLS support network and a third GMPLS support network by using a boundary route protocol. A resource reservation protocol signaling unit(710) searches routes of other networks by referring to the route information. The resource reservation protocol signaling unit executes an inter-network signaling procedure through a signaling interface and the first or the third GMPLS support network.
Abstract:
PURPOSE: A communication control system and a method thereof controlling a communication path or a routing of a communication network and an operation of a communication device are provided to reduce power usage amount of a communication network by controlling the operation state of an unnecessary device. CONSTITUTION: An energy efficiency monitoring unit(100) calculates energy efficiency of a communication device through collecting quantity of traffic consumed and quantity of power consumed of a communication equipment in a communication network. According to a calculated energy efficiency, a device control unit(110) controls operation of a communication device in the communication network. According to operation control of a communication device, a communication network control unit(120) controls routing or a communication path of a communication network.
Abstract:
PURPOSE: The electric power production device, the power demand apparatus, and the power control system and method for controlling electric power manage the real-time information for the electric energy which the supply place holds and electric power production wife. In that way the power supply can be controlled efficiently. CONSTITUTION: The storage(112) stores the information about oneself. The transmission unit transmits a message the information about oneself to the power demand apparatus for being neighbors. The receiver(114) receives a message the power demand request from the power demand apparatus for being neighbors.
Abstract:
PURPOSE: A network control system and a control method thereof enabling each node to control OAM information are provided to enhance the efficiency and flexibility of network operation. CONSTITUTION: A command receiving unit(110) receives a command about each operation policy. A message generating unit(120) generates a message including information about MA operation policy according to the command. A message transmitting unit(130) transmits the message to a controlling unit.
Abstract:
PURPOSE: An optical transmission system is provided to implement more minute distributed compensation with different dispersion compensators according to a band of a signal received in a reception end. CONSTITUTION: A first dispersion compensator(310) recompenses wavelength dispersion based on one wave among signals transmitted through optical fiber. A demultiplexer(320) outputs and separates signals outputted from the first dispersion compensator to different channels according to wavelength. A second dispersion compensator(330) recompenses wavelength dispersion of optical signals of the different wavelength outputted from the channels. A light amplifier amplifies a channel signal branched from the demultiplexer.
