报告题目：Enhancing RAN Throughput by Optimized ControllerPlacement in Optical Metro Networks（AchillePattavina 教授）
摘要：For the upcoming 5G mobile communications, enhanced cellcoordination is deemed as crucial to maximize network throughput. TheCoordinated Multipoint (CoMP) protocol enables the coordination of cellclusters through a Radio Coordination Controller (RCC) to enhance themobile-network throughput by reducing interference. Current metro/aggregationnetworks are characterized by a hierarchical architecture with different levelsof central offices, so the decision of where to place RCC in order to maximizeCoMP throughput gain is not trivial. It depends on several factors, such asgeographical dimension of the network, cluster size and latency experiencedbefore reaching the RCC. It can be shown that the placement of coordinationcontrollers in the metro optical network has a significant impact on theperformance of cell coordination. Under certain conditions an optimizedplacement provides benefits with respect to fixed placement of controllers.
报告人简介：Achille Pattavina received the Dr. Eng.degree in Electronic Engineering from University of Rome (Italy) in 1977. Hewas with the same University until 1991, when he moved to “Politecnico di Milano”,Milano (Italy), where he is Full Professor since 1995. He has beenauthor/coauthor of more than 300 papers in the area of communications systemsand networks and of two books: Switching Theory, Architectures and Performancein Broadband ATM Networks (New York: Wiley, 1998), Communication Network:Networking and Internet (McGraw-Hill, 2nd ed., 2007, in Italian). He has beencoordinator of national and international research activities, including EuropeanUnion funded projects. He has been Editor for Switching Architecture Performanceof the IEEE Transactions on Communications from 1994 to 2011 andEditor-in-Chief of the Wiley European Transactions on Telecommunications from2001 to 2010. His current research interests are in the areas of data centerand cloud computing, software defined networking, optical networks, switchingtheory, broadband convergent access/metro networks.
