Abstract: Disclosed is an optical network unit (ONU) capable of reporting current Dynamic Bandwidth Report upstream (DBRu) information to an optical line terminal (OLT) according to the amount variation of to-be-transmitted upstream data in a buffer. The ONU includes: the buffer temporarily storing the to-be-transmitted upstream data; a register circuit recording previous data amount information related to the previous data amount of the buffer at a previous time point earlier than a current time point; a DBRu information generating circuit generating the current DBRu information according to an amount difference and a current data amount of the buffer at the current time point, wherein the amount difference is dependent on the difference between the previous data amount information and current data amount information that is dependent on the current data amount; and a transmitting circuit transmitting the current DBRu information to the OLT.

Abstract: A device for realizing upstream aggregation and downstream translation of a virtual local area network (VLAN) includes a buffer and a processor. The buffer is used for storing an ingress VLAN translation table and an egress VLAN translation table. The processor is used for translating an upstream packet inputted from a first user port into an upstream translation packet according to the ingress VLAN translation table, and transmitting the upstream translation packet to the Internet through an internet port, and translating a first downstream packet inputted from the internet port into a first downstream translation packet according to the egress VLAN translation table, and transmitting the first downstream translation packet to a user device through a second user port.

Abstract: A network device including an address move detection unit, a loop detection packet generation unit, a packet parser unit and a loop determination unit coupled to the packet parser unit is provided. The address move detection unit detects whether an address field of a first packet received by the network device is moved. The loop detection packet generation unit generates a loop detection packet if the address move detection unit detects that the address field is moved. The packet parser unit parses a second packet received by the network device to extract an information. Based on the information, the loop determination unit determines whether the second packet matches the loop detection packet so as to determine whether there is any loop existing in the network device.

Abstract: A low power consumption network device includes: a data rate meter for detecting a data rate of the network device; a state machine unit for determining a state of the network device according to the data rate and for generating an instruction signal; and a power control unit for controlling a power consumption state of the network device according to the instruction signal. According to the data rate, the state machine unit controls whether the network device transmits a pause frame to a link partner, so that the link partner stops transmitting data to the network device during a pause period. During the pause period, the power control unit controls the network device into a power saving mode.
