Abstract
A bandwidth advertisement update method in an optical network, an optical network, and a controller provide a configurable mechanism for bandwidth advertisement updates in a control plane providing flexibility and reducing bandwidth advertisements in the control plane while concurrently supporting aggregated connections. The bandwidth advertisement update method includes defining a plurality of bandwidth update threshold values for a plurality of bandwidth units supported on a link in the optical network, responsive to a change in available bandwidth on the link, sending a bandwidth advertisement if the available bandwidth for any of the plurality of bandwidth units is less than the associated bandwidth update threshold value, and responsive to a change in available bandwidth on the link, withholding the bandwidth advertisement if the available bandwidth for all of the plurality of bandwidth units is greater than or equal to the associated bandwidth update threshold value.
