The distributed S-NICE enhancements is an evolved version of S-NICE which has already been standardized by ITU-T Recommendations [ITU-T Y.3321] and [ITU-T Y.3322]. This Recommendation specifies the functional architecture of distributed S-NICE based on DLT, defines related functional entities and reference points. This draft Recommendation builds on published S-NICE related Recommendations including [ITU-T Y.3321] and [ITU-T Y.3322], and the content of this draft recommendation is aligned with [ITU-T Y.3326] which specifies the requirements and framework of distributed S-NICE based on DLT.
