Title: A Speed of Light Internet Service Provider
Abstract: A variety of network applications, including electronic commerce and games, are either enabled by or benefit greatly from low latency communications. Studies have shown, however, that over medium and long distances the time to send a packet from one city to another on the public Internet is typically more than three times larger than the lower bound implied by the speed of light in free space. Hence for applications like high-frequency trading, where the winner of a communications race receives all the benefits, special purpose networks have been deployed. For example, between New Jersey and Chicago a succession of networks has been deployed, first fiber-based and then microwave-based, with each network reducing latency by a fraction of a millisecond over the previous. This talk explores the possibility of using the same radio technology to build a network backbone spanning the 120 largest population centers in the United States. The design places radios on existing towers, using topographic maps to ensure line-of-sight connectivity between towers. The impact of weather on the network is evaluated using historical weather data. Our analysis suggests that it should be possible to achieve mean speeds of over 95% of the speed of light over medium and long distances at a transmission cost of under $1 per GB.

Title: Network Operations and AI
Abstract: The Fifth Generation Mobile Networks (5G) are seen as a key enabler for diverse-natured industry verticals (such as automotive, manufacturing, mining, utility, health, etc.) by providing a platform to support heterogeneous sets of network quality requirements. The presentation will discuss how Artificial Intelligence and automation can support Telecom industry to manage the increased complexity, scalability, and diversity in its use cases. The work presents different aspects of the network operations of the future, done in an automated, proactive, and intent-driven fashion using different AI techniques.

Title: Softwarization and IoT evolution
Abstract: The Internet of Things (IoT), a main enabler for Industry 4.0, is considered as a system connecting myriads of people, things and services. IoT enables new large-scale applications with diverse constraints (e.g., limited resource availability or mobility) and requirements (e.g., ultra low delays). A main challenge is the evolution beyond large networks of sensing devices to multiple cooperating network deployments that implement context-sensitive communication and cloud processing strategies, through the seamless adoption of Softwarization technologies. The talk includes the following aspects: (i) a motivation of the above vision with two novel use-cases on smart-city and maritime contexts; (ii) a discussion on the evolutionary and clean-slate approaches to the IoT Softwarization; (iii) the missing elements and open issues in Software-Defined IoT and Edge Cloud technologies; and (iv) insights from our practical experience in relevant implementations and real experiments.

Title: Network Modeling: Finding the Right Level of Abstraction
Abstract: For nearly fifty years, beginning with Kleinrock’s pioneering work on using queueing theory to model packet flows in communication networks, network modeling has adopted the individual packet as primary level of granularity for network modeling and analysis. With the advent of terabit-switching capabilities, information-centric networking, and data centers with complex workloads and hundreds of thousands of components, the time would seem ripe to raise the level of abstraction beyond the packet. In this talk, we identify higher-level modeling abstractions are already proving useful as well as new needed abstractions. But also we identify cases where packet-level models are still crucial in providing important insights.

Title: Refurbishment of the IP Framework after 50 years of operations
Abstract: In the past decades, the Internet has been slowly “fragmented” into Many Networks (ManyNets) due to both technical and commercial reasons. Their incompatible addressing mechanisms hinder the interconnection among those networks. Current Internet Protocol (IP) that aims to connect regional academic and military networks was invented half a century ago. The original IP design philosophy including fixed address length, binding machines to specific locations, and many others might not be suitable for all networks. Furthermore, emerging applications like ARVR, holographic communications, etc. rises new requirements to the network and involves innumerable physical and virtual objects, which requires more efficient and customized network services. In this talk, a novel framework for future Internet protocol will be presented to tackle aforementioned challenges. The new framework will adopt variable-length and multi-semantic network addresses, and enables user-defined networking in order to support futuristic applications.
