Abstract
In one aspect, a method for congestion avoidance in a passive optical network having an optical line terminal communicatively connected to a plurality of optical network termination devices is provided. A dynamic bandwidth allocation information is periodically requested from the optical network termination device and the optical line terminator receives the response to the request. An adjusted bandwidth allocation for the optical network termination device is determined by the optical line terminator. The optical line terminator determines a packet-drop command to be taken at the optical network termination device. The adjusted bandwidth allocation and the packet-drop command are sent to the optical network termination device.
