Bandwidth allocation device and method to guarantee QoS in Ethernet passive optical access network |
摘要 |
The present invention provides a device and method for allocating a bandwidth to a plurality of optical network units (ONUs) for transmitting an uplink frame in the EPON. The bandwidth allocation device includes a plurality of optical network units and an optical line terminal (OLT). The optical network units classify uplink data to be transmitted to an optical line terminal according to a predetermined priority, and transmit the classified uplink data by receiving an allocated bandwidth according to each class from the optical line terminal. The optical line terminal preferentially distributes a predetermined bandwidth for transmitting uplink frames of a highest priority class to the optical network units and then dynamically distributes a remained bandwidth form transmitting the uplink frames for remained classes.
