Method of controlling upstream data transmission in ethernet PON and apparatus thereof

An apparatus which controls data transmission in an Ethernet passive optical network (EPON) using a multi-point control protocol (MPCP), the apparatus comprising:

• a bandwidth allocation unit, which generates transmission permission messages to allocate upstream data transmission bandwidth to each optical network unit (ONU);
• a queuing unit, which queues the transmission permission messages according to types of the transmission permission messages;
• a scheduler, which determines priorities of the transmission permission messages from queues based on registration information of each optical network unit (ONU) that receives the transmission permission messages, determines a transmission start time of upstream data based on a priority, and outputs the transmission permission messages;
• and
• a control unit, which selectively designates static bandwidth allocation and dynamic bandwidth allocation.

A computer readable recording medium on which a program is recorded, the program used for executing the method of controlling data transmission in an Ethernet passive optical network (EPON) using a multi-point control protocol (MPCP), wherein the method comprises:

• (a) generating transmission permission messages using a bandwidth allocation mode and determining a transmission time duration of upstream data corresponding to the transmission permission messages;
• (b) queuing the transmission permission messages according to types of the transmission permission messages;
• (c) determining priorities of the transmission permission messages based on the types of the transmission permission messages and registration information of an optical network unit (ONU) that receives the transmission permission messages;
• and
• (d) determining a transmission start time of upstream data based on a priority and outputting the transmission permission messages.
