Title: Software-Based Networks: Leveraging high-performance NFV platforms to meet future communication challenges
ABSTRACT
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 describe scheduling frameworks for OpenNetVM that enables per-flow 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.

Title:
the Internet of Things and its Security Challenges
ABSTRACT
Internet of Things (IoT) is an emerging technology that has drawn a lot of attention in recent years. Things in IoT can take a wide variety of forms, from simple RFIDs attached to merchandises, smart thermostats installed in the classrooms, implantable medical devices on the patients, to video cameras on top of light poles, and automobiles with built-in sensors. The explosive deployment of IoTs has pushed the boundary of the cyber-world to be tightly intertwined with our physical world. The IoT enables the exchange of information in a variety of application scenarios, each having unique characteristics and requiring unique performance guarantees, and together they bring potentially tremendous benefits to us- home automation, environmental monitoring, health and lifestyle, smart cities, just to name a few.
Some significant risks go along with the potential benefits of the IoT. As we add devices to our cloths, bodies, homes, and environments, more personal information will be collected. Some information is deeply sensitive. As devices are more closely connected with our physical world and some are capable of taking actions, data security and device security become critically important. Last year, IoT devices have also been exploited to launch the largest DDoS attack in history to disrupt the Internet services.
A secure and trustworthy IoT is not an easy task. It demands multiple lines of defense from different layers to thwart attacks from both the physical world and cyberspace. It also requires the integration of security and privacy mechanisms into computing and networking functions. In this talk, I will introduce the network architecture and unique characteristics of IoT systems. I will then focus on unique security and privacy challenges in the IoT. Many of the security and privacy problems are very challenging and call for interdisciplinary expertise from a number of technical domains.
