dc.description.abstract	Cloud or Centralized Radio Access Networks (C-RANs) are expected to be widely deployed under 5G in order to support the anticipated increasedtraffic demands and reduce costs. Under C-RAN, the radio el- ements (e.g., eNB or gNB in 5G) are split into a basic radio part (Distributed Unit, DU),and a pool-able base band processing part (Central Unit, CU). This functional split results in high bandwidth and delay constrained traffic flowsbetween DUs and CUs (referred to as fronthaul), calling for the deployment of a specialized network to accommodate them or for integrating themwith the rest of the flows (referred to as backhaul) over the existing infrastructure. This work studies the next generation of transport networks, which aims at integrating fronthaul and backhaul traffic over the same transport stratum. An optimization framework for routing and resourceplacement is developed, taking into account delay, capacity and path constraints, maximizing the degree of DU deployment while minimizing thesupporting CUs. The frame- work and the developed heuristics (to reduce the computational complexity) are validated and applied to both small andlarge- scale (production-level) networks. They can be useful to network operators for both network planning as well as network operation adjustingtheir (virtualized) infrastructure dynamically.	en
