摘要： A MAC master apparatus for executing a multi-point control protocol (MPCP) data in an optical line termination (OLT) of an Ethernet passive optical network (PON) is provided. The MPCP master apparatus includes a CPU interface unit, two or more memory arbitration control units, a SGA table memory, a RTT table memory, a static grant generation unit, a dynamic grant generation unit, a static grant queue, a dynamic grant queue, a sending message queue, a sending multiplexing unit, a time setting unit, a receiving window generation unit, an upstream grant queue, a received demultiplexing unit, a report queue and a received message queue. Therefore, any frame, including MPCP frames from/to the CPU can be sent or received, and a grant can be allocated statically according to a setting or dynamically according to a report from the ONUs.

摘要： A method of controlling data transmission in an Ethernet passive optical network (EPON) and an apparatus thereof are provided. Transmission permission messages using a mode of bandwidth allocation are queued in a queuing unit according to the types of the transmission permission messages. A transmission time duration of upstream data is defined for each of the transmission permission messages queued in the queuing unit. A bandwidth allocation unit generates transmission permission messages to allocate upstream data transmission bandwidth for an optical network unit (ONU), based on the transmission permission messages stored in the storage unit. A scheduler designates the predetermined priority, reads transmission permission messages from queues according to a predetermined priority, determines a transmission start time of upstream data, and outputs the transmission permission messages.

摘要： Provided is a method of monitoring link performance and diagnosing an active link state without interrupting traffic in an Ethernet passive optical network (EPON) while the link is in the active state. The method of monitoring link performance and diagnosing an active link state without interrupting data flow to logic links which are in active states in the EPON, includes: a) allowing an operator of the EPON to select a link performance monitoring function or a link active state diagnosing function; b-1) if the link performance monitoring function is selected, setting a monitoring cycle timer and periodically transmitting a performance information request frame from a local node to a remote node; b-2) if the remote node receives the performance information request frame, collecting corresponding link performance information and transmitting a response frame from the remote node to the local node in a format which is predetermined in accordance with a corresponding frame format; b-3) if the local node receives the response frame from the remote node, analyzing the performance information of the response frame and determining whether the link performance has deteriorated or if a failure has occurred in the local node; b-4) if the deterioration of the link function or the degree of the failure reaches a predetermined threshold, reporting to an upper layer that a failure has occurred.

摘要： Provided is a method for classifying packets in a cable modem termination system (CMTS) supporting a channel bonding mode. The method includes the steps of: extracting a destination Media Access Control (MAC) address of a received data packet; acquiring a MAC address of a cable modem receiving the data packet, and memory address information of a cable modem Classifier Identifier (CLID) corresponding to the MAC address of the cable modem, from a first classification table corresponding to the destination address; extracting the CLID information present in the memory address; extracting a classifier pattern corresponding to the extracted cable modem CLID information; bonding the MAC address of the cable modem and the classifier pattern to generate a result pattern; extracting a memory address including downstream service flow information from a second classification table corresponding to the result pattern; extracting the downstream service flow information corresponding to the memory address; and generating an output packet corresponding to the downstream service flow information and the data packet.
