Abstract
Official abstract text for this publication.
A connection-oriented optical network ( 2 ) comprises nodes ( 10 ) and optical links ( 5 ) between nodes. Each node ( 10 ) has a power control unit ( 60 ) for controlling an optical amplifier ( 43 ) at the node. A node, in response to a requirement to set up a new connection in the network, signals to a power control unit ( 60 ) at each of a plurality of downstream nodes along a path of the new connection to cause the power control unit at the node to adjust the optical amplifier at the node to support a new optical channel to carry the new connection. The node ( 10 ) can signal to tear down an existing connection in a similar way. A downstream node determines a number of optical channels for which the optical amplifier can be adjusted concurrently, based on an existing number of active optical channels.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of operating a first node in a connection-oriented optical network comprising nodes and optical links between nodes, each node having a power control unit for controlling an optical amplifier at the node, the method comprising, at the first node, at least one of: in response to a requirement to set up a new connection in the network, signalling to the power control unit at each of a plurality of downstream nodes along a path of the new connect…
