Abstract
A method and system for identification of a channel in an optical network is provided. The channel is identified by the use of unique combinations of two or more low frequencies, or tones, modulated onto the channel and optionally, a network parameter associated with the channel.
Claims24
A method for identifying an optical channel in an optical network, comprising the steps of:
- marking the channel with a unique combination of two or more identification tags, the combination of identification tags being referred to as a channel signature, to identify the channel in the network;
- detecting the channel signature at various locations in the network;
- and
- verifying one or more restrictions imposed on the allocation of tones for the channel signature in the network, the step of verifying being performed before the step of marking.
A system for identifying an optical channel in an optical network, comprising:
- means for marking the channel with a unique combination of two or more identification tags, the combination of identification tags being referred to as a channel signature, to identify the channel in the network;
- means for detecting the channel signature at various locations in the network;
- and
- means for verifying one or more restrictions imposed on the allocation of tones for the channel signature in the network.
A method for identifying an optical channel in an optical network, comprising the steps of:
- marking the channel with a unique combination of two or more identification tags, the combination of identification tags being referred to as a channel signature, to uniquely identify the channel in the network and one or more network parameters associated with the channel;
- and
- detecting the channel signature at various locations in the network;
- wherein the step of marking the channel comprises allocating one of the tones in the channel signature for identifying the channel, and allocating one or more of the remaining tones in the channel signature for identifying one or more parameters in the network associated with the channel.
A method for identifying an optical channel in an optical network, comprising the steps of:
- marking the channel with a unique combination of two or more identification tags, the combination of identification tags being referred to as a channel signature, to uniquely identify the channel in the network and one or more network parameters associated with the channel;
- and
- detecting the channel signature at various locations in the network;
- wherein the step of allocating the remaining tones comprises allocating the tones for identifying one or more of the following network parameters associated with the channel:
- (a) an optical band including the channel;
- (b) a source node in the network where the channel signature is marked;
- (c) a destination node in the network where the channel signature is detected;
- (d) an optical fiber carrying the channel;
- and
- (e) an optical cable including the optical fiber carrying the channel.
