Abstract: PURPOSE: A device and a method for processing a distributed object using a priority succession technique are provided to change the priority of a server method according to a request of a client by succeeding the priority requested from the client to the priority of the server method. CONSTITUTION: A priority assigner assigns the priority to the method when the client(101) calls the method of a server object. An IDL(Interface Description Language) stub(102) and a middleware core(103) transfer the called method and the assigned priority to a server(107). A priority processor(104) executes the server object depending on the priority assigned from the client by converting the priority transferred from the IDL stub and the middleware core into a system priority, generating a thread having the system priority, and mapping the generated thread to the called method.

Abstract: PURPOSE: A method and apparatus for dynamically allocating bands by service class are provided to ensure service quality by using ethernet frames for uplink/downlink transmission between ONU(Optical Network Unit) and OLT(Optical Line Terminator) and previously reserving an amount of requested band of each service class of the ONU. CONSTITUTION: When an MPCP(Multi-Point Control Protocol) allocator(210) receives an uplink report control message from a control layer(220), a class queue state calculator(212) discriminates ONUs and acquires length information of queues by class in the ONUs. When queue state information of every ONU is collected, a permission generator(211) generates bands by ONU and bands by service of the ONUs, and transmits downlink band allocation(GATE) control messages by ONU. An MPCP requester(230) receives the downlink band allocation(GATE) control message from an MAC control layer(240). A class buffer counter(232) counts length of buffers of each class of the ONUs, and a request generator(231) generates length information of buffers by class in the ONUs. The generated information is transmitted as an uplink report control message to the MAC control layer(240).

Abstract: PURPOSE: A communication device for an EPON(Ethernet Passive Optical Network) is provided to support uplink/downlink priority-tagged frames, and to support a VLAN(Virtual LAN) multicast in a PON bridge function, thereby constructing a VLAN in the EPON as increasing link efficiency. CONSTITUTION: A PON bridge sub layer(100) comprises as follows. A reception output processor(101) reads data from a reception output queue(105), and changes 32-bit data into an 8-bit signal to transmit the data to a switch or NP(Network Processor)(10). If an overflow is generated in a transmission input queue(106), the reception output processor(101) receives a pause signal from the transmission input queue(106), and generates a pause frame to the switch or NP(10). If the overflow is not generated in the transmission input queue(106), the reception output processor(101) reads the frame, and transmits the frame to the switch or NP(10). The reception output processor(101) performs an FCS(Frame Check Sequence) generation process for the frame only when the pause frame is generated, and sends data to an SPI processor(105).
