Internet-based traffic is dramatically increasing every year. Internet-based traffic is dramatically increasing every year.
Moreover, such traffic is also becoming more dynamic. Thus, Moreover, such traffic is also becoming more dynamic. Thus,
transport networks need to evolve from current DWDM systems towards transport networks need to evolve from current DWDM systems towards
elastic optical networks, based on flexi-grid transmission and elastic optical networks, based on flexi-grid transmission and
switching technologies [RFC7698]. This technology aims at increasing switching technologies [RFC7698]. This technology aims at increasing
both transport network scalability and flexibility, allowing the both transport network scalability and flexibility, allowing the
