A protocol for an optical network can control the time at which subscriber optical interfaces of
an optical network are permitted to transmit data to a transceiver node. The protocol can …

(57) Unlike the conventional art which polices data at the entry points of a network, a
transceiver node can police or monitor downstream bandwidths for quality of service at exit …

A node in an optical communications network receives optical packets at its input. It
determines a priority assigned to each optical packet. When the optical packet is a transit …

The present invention is generally drawn to optical network architecture that can include a
multi-subscriber optical interface that can service a plurality of subscribers that are located in …

A method and system for allocating bandwidth in a communication network is disclosed.
Processing a request for bandwidth includes evaluating potential paths. Configuration rules …

SUMMARY OF THE INVENTION AS the traffic level of large users approaches the line rate
for a Single wavelength of light on a network operator's ring, there is an incentive to permit …

This invention provides an improved graphical user interface (GUI) for optical network
administration. The GUI allows a user to view a network topology in which only those nodes …

In an optical communication network, optical communication nodes exchange information
detailing power level variations to support management and administration of optical …

Packets are received at a first boundary node of a long haul optical communication network
which may either interconnect originating and destination communication networks or form …

An optical transmitter of a subscriber optical interface and an optical receiver of a laser
transceiver node can be designed to a frequency of data that is formatted according to a …
