Abstract:
멀티-홉 네트워크의 데이터 전송 방법 및 이를 위한 장치가 개시된다. 본 발명에 따른 멀티-홉 네트워크의 데이터 전송 방법은 멀티-홉 네트워크의 정보를 수신하는 단계, 소스 노드에서 싱크 노드까지의 데이터 전송에 대한 소정의 요구 전송 신뢰도를 수신하는 단계, 요구 전송 신뢰도를 만족하는, 소스 노드에서 싱크 노드까지의 각 노드의 단일-홉 패킷 전송율을 상기 멀티-홉 네트워크의 정보에 기초하여 결정하는 단계 및 상기 각 노드의 단일-홉 패킷 전송율을 상기 멀티-홉 네트워크를 구성하는 각 노드에 통지하는 단계를 포함하여 구성될 수 있다. 본 발명에 따른 방법 및 장치는, 멀티-홉 네트워크에서 요구하는 요구 전송 신뢰도를 만족하면서, 총 전송 패킷수를 최소화하여 에너지 소모량을 저감하는 효과를 제공한다.
Abstract:
Disclosed is a cell scheduling execution method taking the priority ranking and starvation into account. The cell scheduling execution method according to the present invention prevents a starvation phenomenon from occurring when a cell is meant to be transmitted but cannot be transmitted since the cell has a low priority rank by making the cell have a higher priority rank. Accordingly, the present invention can prevent a starvation phenomenon from occurring when high-priority cells are continuously transmitted from a particular input port to a particular output port and the input queue of another input port with low-priority cells targeting the same output port is not declining.
Abstract:
If a transmitting device transmits an instant message, the transmitting device sets a notification command mode to instruct a notification process if a receiving device receives the message or a non-notification command mode to instruct a non-notification process if the receiving device receives the message. After that, the receiving device performs the notification process if the notification command mode is set in the received message and does not perform the notification process if the non-notification command mode is set in the received message.
Abstract:
PURPOSE: A remote execution test system using a script file, a device thereof, and a method thereof are provided to perform performance control and testing in real time by interlinking a development server with a target system and using a command script file and a multi-performance script file. CONSTITUTION: A script file composed of commands is edited and the command script file is delivered while being interlinked with a target system by using the command script file(1230). The target system receives the command script file to execute the command script file with contents of the file and deliver a performance result to a development server(1250). A result of a command script executed in a target is received to be outputted. [Reference numerals] (1210,1270) Execution waiting state; (1220) Command script file exists?; (1230) Executing a command script file; (1240) Delivering an execution completion message; (1250) Deleting the command script file; (1260) Registering the next execution period; (AA) Start; (BB) No; (CC) Yes;
Abstract:
PURPOSE: A communication node and a communication error process method thereof are provided to rapidly transmit the detected communication failure to the communication node. CONSTITUTION: An environment change sensing unit(112) senses abnormal sign from the sensed environment change. A power sensing unit senses power which is supplied to a communication node. A control signal generating unit transmits a control signal to a storing unit(120) and a transmitting unit(130). The transmitting unit transmits a communication failure notification message to the communication node. A receiving unit(140) receives a communication failure notification message.
