CPC H04J 14/0212 (2013.01) [H04J 14/0213 (2013.01); H04J 14/0227 (2013.01)] | 14 Claims |
1. An Optical Add/Drop Multiplexer (OADM) node comprising
a Wavelength Selective Switch (WSS) connected to the optical section; and
a controller communicatively coupled to the WSS and configured to
receive a request for a capacity change for a plurality of channels on the optical section,
determine a grouping of the plurality of channels in N steps, N is an integer >1, based on an impact to existing traffic-carrying channels, wherein the grouping assigns each of the plurality of channels to a step of the N, steps, and
cause the N steps for the capacity change which includes switching between traffic-carrying channels and channel holders.

6. A method implemented in an Optical Add/Drop Multiplexer (OADM) node comprising:
receiving a request for a capacity change for a plurality of channels on an optical section,
determining a grouping of the plurality of channels in N steps, N is an integer >1, based on an impact to existing traffic-carrying channels, wherein the grouping assigns each of the plurality of channels to a step of the N steps; and
causing the N steps for the capacity change which includes switching between traffic-carrying channels and channel holders.

11. A non-transitory computer-readable medium comprising instructions that, when executed, cause a controller associated with an Optical Add/Drop Multiplexer (OADM) node to perform steps of:
receiving a request for a capacity change for a plurality of channels on an optical section,
determining a grouping of the plurality of channels in N steps, N is an integer >1, based on an impact to existing traffic-carrying channels, wherein the grouping assigns each of the plurality of channels to a step of the N steps; and
causing the N steps for the capacity change which includes switching between traffic-carrying channels and channel holders.
