CEMSE Dean's Distinguished Lecture| Software-Based Networks: Leveraging high-performance NFV platforms to meet future communication challenges

Start Date: February 19, 2018
End Date: February 19, 2018

By Professor K. K. Ramakrishnan (Dept. of Computer Science and Engineering University of California, USA)
 
 
Communication networks are changing. They are becoming more and more “software-based.” The use of
Network Function Virtualization (NFV) to run network services in software, along with the concept of
Software Defined Networks (SDN), will lead to a largely software-based network environment. To truly
achieve the vision of a high-performance software-based network that is flexible, lower-cost, and agile, a
fast and carefully designed NFV platform along with a comprehensive SDN control plane is needed. Our
high-performance NFV platform, OpenNetVM, enables high bandwidth network functions to operate at
near line speed, while taking advantage of the flexibility and customization of low cost commodity servers.
We envision a dynamic and flexible network that can support a smarter data plane than just simple switches
that forward packets. We will briefly describe scheduling frameworks for OpenNetVM that enables perflow
customization and rate-and-cost proportional fair scheduling of flows.
 
Use of OpenNetVM opens up opportunities to re-architect the way networks are put together. As an
example, we demonstrate the utility of OpenNetVM for supporting future cellular networks (e.g., 5G and
beyond). NFV enables dynamic management of capacity to support the Mobile Core Network of future
cellular networks. Truly exploiting the opportunities of a software-based environment requires careful
thinking about the protocols utilized as well. We describe CleanG, a simplified software-based architecture
for the cellular core network with a simplified control plane protocol.
 
Bio: Dr. K. K. Ramakrishnan is Professor of Computer Science and Engineering at the University of California,
Riverside. Previously, he was a Distinguished Member of Technical Staff at AT&T Labs-Research. He
joined AT&T Bell Labs in 1994 and was with AT&T Labs-Research since its inception in 1996. Prior to
1994, he was a Technical Director and Consulting Engineer in Networking at Digital Equipment
Corporation. Between 2000 and 2002, he was at TeraOptic Networks, Inc., as Founder and Vice President.
Dr. Ramakrishnan is an ACM Fellow, an IEEE Fellow and an AT&T Fellow, recognized for his
fundamental contributions on communication networks, including his work on congestion control, traffic
management and VPN services. His work on the "DECbit" congestion avoidance protocol received the
ACM Sigcomm Test of Time Paper Award in 2006. He has published nearly 250 papers and has 166
patents issued in his name. K.K. has been on the editorial board of several journals and has served as the
TPC Chair and General Chair for several networking conferences and has been a member of the National
Research Council Panel on Information Technology for NIST. K. K. received his MTech from the Indian
Institute of Science (1978), MS (1981) and Ph.D. (1983) in Computer Science from the University of
Maryland, College Park, USA.
