MECHANISM FOR TRAFFIC PRIVACY IN RECONFIGURABLE ADD/DROP MULTIPLEXER BASED SUBMARINE NETWORKS

摘要

A method for data transport that includes providing a branch terminal between a first and second trunk terminal, wherein a branching unit is present at an intersect between the first and second trunk terminal and the branch terminal. The branching unit includes a reconfigurable add/drop multiplexers (ROADM) at least one attenuator. A signal is sent from a second terminal of the first and second trunk terminal to the branding unit. The signal may include a branch traffic component trunk traffic component. The branching unit includes at least one attenuator for attenuating the trunk traffic component so that the trunk traffic component of the signal cannot be detected at the branch terminal.

1. A method for data transport comprising:
providing a network including at least one branch terminal and at least one trunk terminal, wherein a branching unit is present at an intersect between the at least one trunk terminal and the at least one branch terminal, the branching unit including a reconfigurable add/drop multiplexers (ROADM) sub unit and at least one attenuator; sending a signal from a sending trunk terminal of the at least one trunk terminal to the branching unit, the signal including a branch traffic component and a trunk traffic component; removing the trunk traffic portion from the signal with the reconfigurable add/drop multiplexers (ROADM) sub unit filter, and attenuating the trunk traffic portion with the attenuator at the branching unit; and combining an attenuated trunk traffic portion with the signal being sent to the branch terminal from the sending terminal so that the trunk traffic portion of the signal that is combined with the attenuated trunk traffic portion of the signal cannot be detected by the branch terminal.
