Home Network Control System and Data Flow Control Method of Above the Home Network Control System

摘要

The present invention provides a home network control system comprising a server and a home network HomNet products, the groove the network part is provided with a first buffer and add the data to the internal process space, the processing instructions stored in said first buffer unit, and a microcomputer including a function to check the state of the first buffer unit capacity; And the HomNet first communication modem for communicating with the server unit; comprises a, the HomNet server program product for controlling a home network is mounted, the control program and control the home network that is responsible for communication between the home network products protocol library module unit; Flow control unit comprising a function for requesting the first buffer portion of the capacity, to the microcomputer the microcomputer; And the first communication unit and second communication modem unit modem communication takes place directly; characterized by comprising a ; In addition, the data flow control in the home network control system according to the invention method steps, which are transmitted to the flow control instruction generated by the control program via a home network control protocol a library module; Flow control requires a check of the microcomputer to an empty buffer capacity within the home network products, the microcomputer proceeds to pass the current state of the buffer capacity to the flow controller; Flow control unit judging that whether or not there is sufficient capacity in the buffer for the processing of the command to examine the buffer status; And if flow control is determined that the capacity of the buffer for the processing of the command is sufficient to transmit to the microcomputer in the command buffer unit comprises a microcomputer for processing. As in the ; or more, The present invention provides a home network control protocol (LG HomNet corresponding to LnCP If the Protocol) protocol, and the lower parts of the module library the home network by the product between the flow control (Flow Controller) that controls the data flow more implementing a home network control protocol library module preempt negative error rate can be improved to further improve the efficiency of network transmission / reception.
