Abstract
Systems and methods include, responsive to provisioning a media channel (52) on a degree, wherein the media channel (52) is a contiguous portion of optical spectrum supporting N channels, N is greater than 1, causing allocation of optical filter bandwidth in an optical multiplexing/demultiplexing device for M channels (56) in the media channel (50), where M is less than N; causing provisioning of the M channels (56) in the media channel (50); and causing configuration of channel holders in the media channel from a channel holder source (20) for a part of the portion of the optical spectrum unoccupied by the M channels (56).
Claims20
A method implemented in a network management system comprising steps of:
- receiving a request for a media channel that is initially not fully occupied, wherein the media channel includes a bandwidth intent for a plurality of network media channels;
- determining optical spectrum for the media channel where the optical spectrum encompasses the bandwidth intent including occupied network media channels and non-occupied network media channels of the plurality of network media channels;
- and
- causing configuration of the media channel, via setting ports on a wavelength selective switch (WSS), between traffic on occupied portions of the optical spectrum for the occupied network media channels and channel holders on non-occupied portions of the optical spectrum for the non-occupied network media channels, such that the media channel is configured as fully occupied while having the non-occupied network media channels included in the bandwidth intent.
A network management system comprising one or more processors and memory storing instructions that, when executed, cause the one or more processors to:
- receive a request for a media channel that is initially not fully occupied, wherein the media channel includes a bandwidth intent for a plurality of network media channels,
- determine optical spectrum for the media channel where the optical spectrum encompasses the bandwidth intent including occupied network media channels and non-occupied network media channels of the plurality of network media channels, and
- cause configuration of the media channel, via setting ports on a wavelength selective switch (WSS), between traffic on occupied portions of the optical spectrum for the occupied network media channels and channel holders on non-occupied portions of the optical spectrum for the non-occupied network media channels, such that the media channel is configured as fully occupied while having the non-occupied network media channels included in the bandwidth intent.
A non-transitory computer-readable medium comprising instructions that, when executed, cause one or more processors to perform steps of:
- receiving a request for a media channel that is initially not fully occupied, wherein the media channel includes a bandwidth intent for a plurality of network media channels;
- determining optical spectrum for the media channel where the optical spectrum encompasses the bandwidth intent including occupied network media channels and non-occupied network media channels of the plurality of network media channels;
- and
- causing configuration of the media channel, via setting ports on a wavelength selective switch (WSS), between traffic on occupied portions of the optical spectrum for the occupied network media channels and channel holders on non-occupied portions of the optical spectrum for the non-occupied network media channels, such that the media channel is configured as fully occupied while having the non-occupied network media channels included in the bandwidth intent.
