ChangesVer-02 to Ver-03Modified Changed the term “group” to “slot”

in the

n_start

and

n_end

fields in the label

Added (similar to RFC4328)a new G-PID type = OTUadapt See (ITU-T SG15, Contribution C1573r1, Dec 2011 (Geneva))a new G-PID value to be assigned by IANAA new Switching Type = Super-Channel-Switch-Capable(SCSC) See draft-dhillon-ccamp-super-channel-ospfte-ext)LSP Encoding Type = Lambda (as defined in RFC4328)

Proposal - SummaryExtends [RFC3471] [RFC6205] Defines a new generalized label format for super-channels assignment on flex-grid networksSuper-Channel Label extensions summaryAllows label assignment for both Contiguous Spectrum and Split-Spectrum Super-Channels Provides two encoding options for the labelList/Range (n_start, n_end)Bitmap

MotivationCoexistence of super-channels using different modulation formats Adjacent super-channels may affect each other detrimentallyDesirable to evaluate the mutual impact of the existing and new super-channels on each other's quality of transmission

Use CaseSignal optical parameters of the super-channel in the RSVP message using proposed TLVsEach node along

the super-channel

setup path allocates the required number of

slices and learns

the associated set of signaled

parameters.

Each node advertises this information to other nodes in the network using routing extensions (see draft-hussain-ccamp-super-channel-param-ospfte) to apply added constraints14draft-hussain-ccamp-super-channel-param-sig-00Slide15
