题目:On the Placement of BBU Hotels in an Optical Access/Aggregation Network for 5G Transport
Abstract. 5G mobile access targets unprecedented performance, not only in terms of higher data rates per user and lower latency, but also in terms of network intelligence and capillarity. To achieve this, 5G networks will resort to solutions as small cell deployment, multipoint coordination and Centralized Radio Access Network (C-RAN) with Baseband Units (BBUs) hotelling. As adopting such techniques requires a high-capacity low-latency access/aggregation network to support backhaul, radio coordination and fronthaul traffic, optical access/aggregation networks based on Wavelength Division Multiplexing are considered as an outstanding candidate for 5G-transport. By physically separating BBUs from the corresponding cell sites, BBU hotelling promises substantial savings in terms of cost and power consumption. However, this requires to insert additional high bit-rate traffic, i.e., the fronthaul, which also has very strict latency requirements. Therefore, a trade-off between the number of BBU hotels (BBU consolidation), the fronthaul latency and network-capacity utilization arises.

        Bio. Achille Pattavina received the Dr. Eng. degree in Electronic Engineering from University of Rome (Italy) in 1977. He was with the same University until 1991, when he moved to “Politecnico di Milano”, Milano (Italy), where he is Full Professor since 1995. He has been author/coauthor of more than 300 papers in the area of communications systems and networks and of two books: Switching Theory, Architectures and Performance in Broadband ATM Networks (Wiley, 1998), Communication Networks: Networking and Internet (McGraw-Hill, 2007). He has been coordinator of national and international research activities, including European Union funded projects. He has been Editor for Switching Architecture Performance of the IEEE Transactions on Communications from 1994 to 2011 and Editor-in-Chief of the Wiley European Transactions on Telecommunications from 2001 to 2010. His current research interests are in the areas of data center and cloud computing, software defined networking, optical networks, switching theory, broadband convergent access/metro networks.
