Network diagnostic tool for an optical transport network
First Claim
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.
