OPTICAL LINE TERMINAL IN GIGABIT PASSIVE OPTICAL NETWORK AND METHOD FOR TRANSMITTING BROADCAST FRAME USING THE SAME

摘要

Disclosed are an optical line terminal in a gigabit passive optical network and a method for transmitting a broadcast frame using the same. The optical line terminal allocates second port identifiers to optical network units such that a broadcast frame is prevented from being retransmitted to an optical network unit which has transmitted the broadcast frame to the optical line terminal.
