Abstract:

It is likely that future Internet traffic will be dominated by on-demand streaming and interactive media flows, such as IPTV, 3D/HD video, gaming, virtual reality, and many more. Such emerging applications are bandwidth-intensive and require a specific service level guarantees in order to be usable (i.e., fulfilling users expectations). Consequently, future network architectures will need to offer predictable performances to such applications, while ensuring scalability in order to meet the large bandwidth requirement. Moreover, the success of such bandwidth intensive applications, together with the opportunity for service providers to benefit from new sources of revenue, is dependent on the cost of such predictable service. Consequently, over-provisioning, which is the basis for providing predictable services on todays networks, is not likely be a viable solution to accommodate these growing new types of traffic. The talk presents a low complexity, hence scalable, network and switching solution to integrate different applications so that each receives the service it requires, possibly in a deterministically guaranteed fashion, while ensuring high resource utilization efficiency. This is key in enabling new services on the future Internet that might be both valuable to end users and beneficial to service providers and telecom operators as a new source of revenue.

Bio:

Mario Baldi is Associate Professor of Computer Networks at the Department of Computer Engineering of Politecnico di Torino (Technical University of Turin), Italy, Project Manager of the PoliTong Sino-Italian Campus at Tongji University, Shanghai, China, and coordinator of the BSc programme in Information Technology Engineering.

He received his M.S. Degree Summa Cum Laude in Electrical Engineering in 1993, and his Ph.D. in Computer and System Engineering in 1998 both from Politecnico di Torino. He was Assistant Professor at Politecnico di Torino from 1997 to 2002. He was Vice President for Protocol Architecture atSynchrodyne Networks, Inc., New York, from November 1999 till October 2001. He was head of the Computer Networks Group (NetGroup) at the Department of Computer Engineering of Politecnico di Torino from 2001 till 2007.

Mario Baldi has been Honorary Visiting Professor at La Trobe University, Melbourne, Victoria, Australia, Adjunct Professor at University of Illinois at Chicago, Visiting Professor at Institut de Technologie du Cambodge, Phnom Penh, Cambodia, and visiting researcher at the IBM T. J. Watson Research Center, Yorktown Heights, NY, at Columbia University, New York, NY, and at the International Computer Science Institute (ICSI), Berkeley, CA.

As part of his extensive research activity Mario Baldi has been leading various networking research projects, involving Universities and industrial partners, funded by European Union, Local Government, and various companies, including Telecommunications Carriers, such as Infostrada and Telecom Italia, vendors, such as Cisco Systems, Inc. and Intel, and research institutions, such as Telecom Italia Labs and Microsoft Research.

He co-authored over 100 papers on various networking related topics and two books, one (currently at the second edition) on internetworking and one on switched local area networks.

Mario Baldi is co-inventor in eleven patents issued by the United States Patent Office in the field of optical networking, in eight pending applications to the United States Patent Office in the fields of high performance networking and security, and one application to the European Patent Office in the field of high performance networking.

His research interests include internetworking, high performance switching, optical networking, quality of service, multimedia over packet networks, voice over IP, and computer networks in general.
