Appeal 2007-1114
Application 10/314,687
BACKGROUND
Appellants’ invention relates to systems and methods for selectively
diverting data from nodes in an optical network. An understanding of the
invention can be derived from a reading of exemplary claim 21, which is
reproduced below.
21. A communication system comprising:
a switching node for switching data packets; and
an optical bypass system configured to receive an optical signal
comprising a data packet and a header, the optical bypass system
operable to selectively divert the optical signal away from the
switching node, the optical bypass system comprising:
an optical switch configured to receive a first portion of the
optical signal, and selectively divert the optical signal away from the
switching node in response to an optical switch control signal
provided thereto;
an optical-to-electrical (O/E) converter configured to receive a
second portion of the optical signal and generate an electrical signal
comprising the header;
a bypass control system configured to generate a bypass control
signal; and
a switching control system communicatively coupled to the
bypass control system and the O/E converter, the switching control
system configured to receive at least one of the bypass control signal
and the electrical signal comprising the header, and to generate in
response thereto, the optical switch control signal for controlling the
optical switch.
