Application 10/054,009
The disclosed invention relates to a method and apparatus for
diagnosing an optical transport network that includes a plurality of network
elements.
Claim 1 is illustrative of the claimed invention, and it reads as
follows:
1. A network diagnostic system for an optical transport network
having a plurality of network elements, comprising:
a first network element residing in the optical transport
network, the first network element having a network diagnostic
operation integrated therein and operable to perform the
network diagnostic operation, wherein the network diagnostic
operation directly monitors an optical signal traversing the
optical transport network; and
a network diagnostic device in data communication with
a second network element residing in the optical transport
network and operable to initiate the network diagnostic
operation at the first network element;
the second network element adapted to receive a request
to initiate the network diagnostic operation from the network
diagnostic device, the second element operable to map the
request into at least one optical network frame and transmit the
optical network frame over an optical supervisory channel of
the optical transport network to the first network element.
The reference relied on by the examiner as evidence of unpatentability
is:
