Abstract: A Dynamic bandwidth allocation method using OLT (Optical Line Terminal) and ONU (Optical Network Unit) for use in GE-PON (Gigabit Ethernet Passive Optical Network) system is disclosed. The OLT's scheduler performs scheduling upon receiving multiple-queue request information contained in the REPORT message from the ONU, and transmits a combined scheduling result associated with one ONU using a GATE message. An ONU's scheduler performs scheduling upon receiving a bandwidth allocated by the OLT, and allocates a transfer bandwidth to its own queues.

Abstract: An Ethernet device having multiple lanes and a method of operating the lanes are provided. In one general aspect, it is possible to allocate a dummy block to each of one or more lanes such that the lanes do not selectively participate in communications. In addition, on a receiving side, the dummy block can be removed from among the genuine data blocks to enable data to be decoded. In this case, an Ethernet device on a transmission side and an Ethernet device on a receiving side can exchange information of a lane to which the dummy block is allocated by use of a lane status message, and the lane status message may be based on a link fault message specified by Ethernet standards.
