K. Ramakrish nan\, UC Riverside DTSTART:20210603T140000Z DTEND:20210603T150000Z UID:TALK160414@talks.cam.ac.uk CONTACT:Srinivasan Keshav DESCRIPTION:Communication networks are changing. They are becoming more an d more “software-based.” The use of Network Function Virtualization ( NFV) to run network services in software\, along with the concept of Softw are Defined Networks (SDN)\, is leading to a largely software-based networ k environment. Our high-performance NFV platform\, OpenNetVM\, enables hig h bandwidth network functions to operate at near line rate\, while taking advantage of the flexibility and customization of low-cost commodity serve rs. \n\n5G cellular networks are trying to meet the needs of an increasing number of users and new applications that require low latency and high ba ndwidth. An impediment to this is the significant latency and overhead co ntributed by the 3GPP-specified complex control-plane for cellular network s. In conjunction with the dynamic management of capacity\, NFV can serve as an ideal platform to support future cellular networks. However\, truly exploiting the opportunities of a software-based environment requires care ful thinking about the cellular network protocols as well. \n\nWe propose CleanG\, a new packet core architecture and a significantly more efficient control-plane protocol\, exploiting capabilities of current Network Funct ion Virtualization (NFV) platforms.\nWith the elastic scalability offered by NFV\, the data and control sub-components of the packet core can scale\ , adapting to workload demand. CleanG eliminates the use of GTP tunnels fo r forwarding data and the associated complex protocol for coordination acr oss multiple\, distributed components for setting up and managing them. We have developed CleanG on top of our OpenNetVM NFV platform. In this talk I will describe our work on CleanG\, after a high-level overview of our Op enNetVM NFV platform. \n\n\nBio:\n\nDr. K. K. Ramakrishnan is Professor o f Computer Science and Engineering at the University of California\, River side. 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-R esearch since its inception in 1996. Prior to 1994\, he was a Technical Di rector and Consulting Engineer in Networking at Digital Equipment Corporat ion. Between 2000 and 2002\, he was at TeraOptic Networks\, Inc.\, as Foun der and Vice President. \n \nDr. Ramakrishnan is an ACM Fellow\, IEEE Fell ow and an AT&T Fellow\, recognized for his fundamental contributions on co mmunication networks\, congestion control\, traffic management\, VPN servi ces\, and a lasting impact on AT&T and the industry. His work on the "DECb it" congestion avoidance protocol received the ACM Sigcomm Test of Time Pa per Award in 2006. He has published nearly 300 papers and has 185 patents issued in his name. K.K. has been on the editorial board of several journa ls and has served as the TPC Chair and General Chair for several networkin g conferences. K. K. received his MTech from the Indian Institute of Scie nce (1978)\, MS (1981) and Ph.D. (1983) in Computer Science from the Unive rsity of Maryland\, College Park\, USA.\n LOCATION:https://cl-cam-ac-uk.zoom.us/j/4361570789?pwd=Nkl2T3ZLaTZwRm05bzR TOUUxY3Q4QT09&\;from=addon END:VEVENT END:VCALENDAR
