3 Chairs feedbacks Ramki and Diego: Below are our thoughts on the Unifying Carrier and Cloud Networks: Problem Statement and Challenges draft. Link to draft: This draft lacks detailed implementation example(s) Our suggestion is to merge this draft with which delves deeper into implementation examples. 3 / 13
4 Updates in 02 New Sec 5: Relation to ETSI NFV Revised Sec 6: Examples 4 / 13
