Chairs feedbacks Ramki and Diego: Below are our thoughts on the Unifying Carrier and Cloud Networks: Problem Statement and Challenges draft. Link to draft: https://datatracker.ietf.org/doc/draft-unify-nfvrg-challenges/ This draft lacks detailed implementation example(s) Our suggestion is to merge this draft with https://datatracker.ietf.org/doc/draft-unify-nfvrg-recursiveprogramming which delves deeper into implementation examples. 3 / 13
