Abstract: Methods and apparatus for providing enhanced optical networking service and performance which are particularly advantageous in terms of low cost and use of existing infrastructure, access control techniques, and components. In the exemplary embodiment, current widespread deployment and associated low cost of Ethernet-based systems are leveraged through use of an Ethernet CSMA/CD MAC in the optical domain on a passive optical network (PON) system. Additionally, local networking services are optionally provided to the network units on the PON since each local receiver can receive signals from all other users. An improved symmetric coupler arrangement provides the foregoing functionality at low cost. The improved system architecture also allows for fiber failure protection which is readily implemented at low cost and with minimal modification.

Abstract: A method for controlling congestion of traffic, by one of one or more User Terminals (UTs), traversing an intermediate node, the method comprising: associating one or more traffic flows of a priority to one of the one or more UTs; detecting a traffic congestion for the priority; performing Random Early Detection (RED) congestion control for the priority to relieve the traffic congestion; selecting, for the priority, a User Terminal (UT) with a perceived delay greater than a high threshold; and controlling, by priority, the traffic flows associated with the selected UT.
