Abstract:
A method and a system for setting up a bandwidth in a subscriber terminal-based access network and a subscriber terminal for implementing the same are provided to stably and efficiently utilize network resources as a subscriber takes the lead in reserving network resources for a P2P(Peer to Peer) service. If a subscriber terminal transmits a P2P service connection request signal to a P2P server, the P2P server transmits a service admission message to the subscriber terminal(S501,S502). An agent of the subscriber terminal creates a socket by using an IP address for the P2P server and a port number for a P2P service and makes ready to receive packets(S503). The agent collects statistical information about the P2P service for 1 second for real-time processing(S504). Then, the agent deduces bandwidth of the P2P service based on the collected statistical information(S505). The agent transmits a P2P service bandwidth allocation request message to a daemon agent of an access network(S506). The daemon agent sets up bandwidth of the P2P service as the bandwidth contained in the P2P service bandwidth allocation request message(S507). Then, the daemon agent transmits a bandwidth setup confirmation message to the subscriber terminal in order to inform the subscriber terminal that the bandwidth has been established(S508).
Abstract:
PURPOSE: A method for controlling communication between a cell multiplexer/demultiplexer and plural master processors is provided to perform state management with a protocol where one lower unit periodically notifies a service available state, not by making plural upper processors monitor a connection state of one lower unit. CONSTITUTION: If a cell multiplexer/demultiplexer is turned on, an initialization code is performed(411). Each IPC(Inter Processor Communication) channel for 8 pairs processors is set through IPC addresses of the processors automatically calculated from an address of the cell multiplexer/demultiplexer(412). An on-line state of the cell multiplexer/demultiplexer is broadcasted to the 8 pairs processors through a message requesting a response of an application block in charge of operation, control and management(413). If any response message is not received from the 8 pairs upper processors, it is regarded that an application block managing the cell multiplexer/demultiplexer does not exist and contents of a transmission/receiving search table are configured as default(415). If a response message is received from one of the 8 pairs processors, contents of the transmission/receiving search table are changed according to system configuration to update the table(416). If a message to change the transmission/receiving search table due to addition or removal of a processor is delivered(417), contents of the transmission/receiving search table are changed(416). And the cell multiplexer/demultiplexer diagnoses its board state and other board states through the IPC channels, to periodically deliver the diagnosed states to each processor.
Abstract:
PURPOSE: An error managing system is provided to improve reliability and availability of a multiplexing exchange control system by automatically recovering system error. CONSTITUTION: An error managing system comprises a manager module(411) and an agent module(412). The agent module(412) is placed at a master and standby processor module respectively. The agent module(412) monitors a state in a corresponding processor module to report the manager module(411) the state information, and recovers an error according to a direction of the manager module(411). The manager module(411) is placed in an input/output processor module(421), and parses the state information from the agent module. If an error arises, the manager module(411) directs the agent module to perform error recovery.

Abstract:
본 발명은 이중 포트램(DPRAM)을 이용한 측정가능 프로세서 구조(SPARC) 계열의 SBus와 MPC860의 통신장치 구현방법에 관한 것으로서, 고속이며, 데이터의 손실을 최소화하면서 메시지를 주고받을 수 있는 이중 포트램을 사용하는 방법을 구체화하였다. 실제로 메시지의 길이가 길거나 대량인 경우 즉, 다운로딩 등을 할 때에는 DPRAM을 이용하는 방법이 효과적이지 않으나, 그렇지 않은 경우에는 전송 매체나 프로토콜을 거치지 않아도 되므로 가격 및 데이터 손실 방지 측면에서 훨씬 좋은 성능을 보이는 효과를 가진다.
