ERC Networking 2018 meets in Budapest on Friday, August 24, during the ACM SIGCOMM 2018 conference. The symposium brings together researchers and educators for the purpose of presenting and discussing research results and ideas pertaining to projects funded by the European Research Council (ERC). The ERC Networking program consists exclusively of invited talks by ERC grant holders, with two types of presentation being envisaged:

(1) Exciting new ideas. Similar in style to ACM HotNets workshop talks, these presentations are intended to generate lively discussions on research topics of high interest.

(2) ERC research results. Presentations of this kind report on results obtained as part of ERC-funded projects.

The European Research Council (ERC) has a mission to encourage the highest-quality research in Europe through competitive funding and to support excellent science driven by individual investigators. Being investigator-driven bottom-up in nature, the ERC approach encourages researchers to identify promising directions and exciting opportunities. The ERC Networking 2018 symposium pursues the following two goals: (i) promoting excellent European research within, or closely related to, the area of computer networking by exposing ERC-funded results and ideas and (ii) inspiring talent in computer networking from all over the world and encouraging applications for ERC grants.


Attendance of the symposium is by open registration and subject to the same registration fees and rules as a regular SIGCOMM 2018 workshop. The attendees who register for another SIGCOMM 2018 workshop on August 24 may freely attend the ERC Networking symposium. Similarly, the registrants of ERC Networking 2018 may freely attend the other workshops on August 24.

    • Title: Advances in Deep Packet Inspection for Next Generation Network Devices

      Abstract: Deep Packet Inspection (DPI) aims to identify packets that contain a pattern from a large set of known patterns (e.g., codes of viruses etc.). In this talk I will present advanced DPI techniques that overcome and address the following issues related to DPI:
      1. Faster and scalable solutions in terms of speed (throughput) memory requirements and power consumption.
      2. DPI algorithms for compressed and other non-clear traffic.
      3. DPI techniques that are more immune and can stand DDoS DPI complexity attacks.
      4. a holistic design of a DPI service as part of a software-defined framework for virtual network functions (VNF). The DPI service supports multi-tenant and presents a significant improvement both in scalability, security and functionality.

    • Title: How to Build a Secure Positioning System

      Abstract: In this talk I will review security issues in today's navigation and close-range positioning systems. I will discuss why GNSS systems like GPS are hard to fully secure. I will then show how a different design of a positioning system can enable secure positioning, but also that this requires solving a set of relevant physical- and logical- layer challenges. Finally I will present a design and implementation of an IR UWB secure distance measurement (distance bounding) system that solves these challenges and enables secure distance measurement and secure positioning in IoT applications. Finally, I will review possible uses of positioning in security applications such as authentication and access control.

    • Title: ARTEMIS: Neutralizing BGP Hijacking within a Minute

      Abstract: BGP prefix hijacking is a critical threat to Internet organizations and users. Despite the availability of several defense approaches (ranging from RPKI to popular third-party services), none of them solves the problem adequately in practice. They suffer from: (i) lack of detection comprehensiveness, allowing sophisticated attackers to evade detection, (ii) limited accuracy, especially in the case of third-party detection, (iii) delayed verification and mitigation of incidents, reaching up to days, and (iv) lack of privacy and of flexibility in post-hijack counteractions, from the side of network operators. In this work, we propose ARTEMIS, a defense approach (a) based on accurate and fast detection operated by the AS itself, leveraging the pervasiveness of publicly available BGP monitoring services and their recent shift towards real-time streaming, thus (b) enabling flexible and fast mitigation of hijacking events. Compared to previous work, our approach combines characteristics desirable to network operators such as comprehensiveness, accuracy, speed, privacy, and flexibility. Finally, we show through real-world experiments that, with the ARTEMIS approach, prefix hijacking can be neutralized within a minute.

  • Wolfgang Kellerer

    • Title: How Flexible is Your Network? A Proposal to Quantify Flexibility in Softwarized Networks

      Abstract: Empowering flexibility is a common objective of softwarized networks based on concepts such as Network Virtualization, Software Defined Networking and Network Function Virtualization. Up to now, flexibility is mainly used as a qualitative advantage for a certain design choice. Moreover, the meaning of flexibility in such qualitative argument is highly varying in the literature since a common understanding of flexibility is missing. In this talk, an approach towards defining flexibility and a proposal for a quantifying measure are presented. Based on this measure, different network designs can be analyzed and compared quantitatively. In our proposal, we refer to flexibility as the timely ability to support new requests that can be, e.g., changes in the requirements or new traffic distributions. Use case studies illustrate how an application of such measure could lead to a better understanding of flexibility. With our proposed flexibility measure, we would like to stimulate the discussion towards a more quantitative analysis of softwarized networks and beyond.

  • Angel Lozano

    UPF, Spain

    • Title: Post-Cellular Wireless Networks

      Abstract: Wireless traffic grows relentlessly, poised to increase to truly staggering levels. There is a fledging awareness that this challenge can only be fended off by a process of network massification, with two views about it. In a first view, densification is the only strategy through which dramatic improvements can be attained hereafter; this leads to a vision where base stations become tiny and exceedingly abundant. A second view is built on the idea of dramatically scaling the number of colocated antennas per base station, from the current handful to possibly hundreds. Since neither form of massification can by itself resolve the challenge facing wireless systems, the two forms will have to end up coexisting. Reconciling these two forms of massification and enabling a truly phenomenal scaling calls for an entirely new architecture where cells and physical base stations become things of the past, replaced by dynamically defined virtual base stations. The signal processing needs to shift away from base stations, which become deconstructed, so as to gather at new places. In this talk, we discuss the implications of this leap in the evolution of wireless networks, and the research challenges that it poses.

    • Title: A Next-generation Secure Internet for the 21st Century

      Abstract: The Internet has been successful beyond even the most optimistic expectations. It permeates and intertwines with almost all aspects of our society and economy. The success of the Internet has created a dependency on communication as many of the processes underpinning the foundations of modern society would grind to a halt should communication become unavailable. However, much to our dismay, the current state of safety and availability of the Internet is far from commensurate given its importance.
      Although we cannot conclusively determine what the impact of a 1-day, or 1-week outage of Internet connectivity on our society would be, anecdotal evidence indicates that even short outages have a profound negative impact on society, businesses, and government. Unfortunately, the Internet has not been designed for high availability in the face of malicious actions by adversaries. Recent patches to improve Internet security and availability have been constrained by the current Internet architecture, business models, and legal aspects. Moreover, there are fundamental design decisions of the current Internet that inherently complicate secure operation.
      Given the diverse nature of constituents in today's Internet, another important challenge is how to scale authentication of entities (e.g., AS ownership for routing, name servers for DNS, or domains for TLS) to a global environment. Currently prevalent PKI models (monopoly and oligarchy) do not scale globally because mutually distrusting entities cannot agree on a single trust root, and because everyday users cannot evaluate the trustworthiness of each of the many root CAs in their browsers.
      To address these issues, we propose SCION, a next-generation Internet architecture that is secure, available, and offers privacy by design; that provides incentives for a transition to the new architecture; and that considers economic and policy issues at the design stage. We have implemented SCION and deployed it in the production networks of 2 ISPs.

  • Costin Raiciu

    UPB, Romania

    • Title: Network Verification without Policy Specification

      Abstract: Networks are critical components of our society; when they fail, they cause massive disruption. Network verification analyzes snapshots of network data planes to decide if the network as a whole behaves according to some predefined policy. Despite massive advances in network verification recently, specifying the policy a network should obbey is far from easy, and this is one of the resons why network verificaiton has not been adopted widely.
      In this work we will discuss how one can verify certain forms of network correctness without requiring explicit policies. In both approaches, our aim is to find behaviours that are obviously wrong, and flag them to the user:
      1. Verifying P4 programs: we show how we can use exhaustive symbolic execution to find memory bugs, encapsulation and decapsulation bugs, implicit processing, parser problems in all the P4 programs that are available publicly, with modest runtimes.
      2. Equivalence: in many cases, two dataplane programs are meant to behave similarly. For instance, an abstract network configuration is specified by tenants in datacenters (e.g. in Openstack) and the cloud software translates this to a dataplane configuration that is deployed (e.g. via Openflow and iptables rules). We show how we can automatically check the equivalence of two network data planes, and how we have used this approach to find several bugs in Neutron, Openstack¹s networking driver.

      Bio: Costin Raiciu is Associate Professor at University Politehnica of Bucharest where he leads the Netsys group. Costin finished his PhD at UCL in 2011.

    • Title: Deep Dive into BGP Communities

      Abstract: Today, our economy as well as our social life, rely on the smooth and uninterrupted operation of the Internet. To cope with the increasing complexity of inter-networking, network operators rely on advanced traffic engineering techniques, such as BGP communities, i.e., meta-information regarding prefix announcements. In this talk, I show that, indeed, the use of BGP communities is on the rise, but more importantly, it provides an excellent, yet unexplored, source of information to assess the state and health of the Internet. In particular, I show how we utilized BGP communities as a crowd-sourcing mechanism to: (i) detect outages at critical peering infrastructures and pinpoint the epicenter of the outage at the level of a building, (ii) detect mitigation of distributed denial of service, and (iii) infer network policies and assess the level of collaboration among networks. I conclude my talk by presenting shortcomings of the use of BGP communities and suggest ways to overcome them via better coordination of all the involved stakeholders.

      Bio: Georgios Smaragdakis is a Professor with Technical University (TU) Berlin, a research affiliate with the Massachusetts Institute of Technology (MIT) Computer Science and Artificial Intelligent Laboratory (CSAIL) and the MIT Internet Policy Research Initiative (IPRI), and a research collaborator with Akamai Technologies.

  • Klaus Wehrle

    RWTH, Germany

    • Title: Symbolic Analysis of Software-based Communication Systems

      Abstract: The softwarization of networks provides a new degree of flexibility in network operation. But its software components can result in unexpected runtime performance and erratic network behavior. This challenges the deployment of flexible software functions, so-called Network Functions (NF), in performance critical (core) networks.
      To address this challenge, we propose Symbolic Execution as a rigorous and effective methodology enabling a qualitative and quantitative analysis of Network Functions, before deployment.
      The talk shows how symbolic analysis methods can be applied in various aspects of networked systems, how the computational challenges can be tackled and that very insidious bugs can be discovered in widely used software.

      Bio: Klaus Wehrle is professor of Computer Science and head of the Chair of Communication and Distributed Systems at RWTH Aachen University, Germany. He received his Diploma and PhD degrees from University of Karlsruhe (now KIT).

    • Title: Efficient Networking in Millimeter Wave Bands

      Abstract: State-of-the-art wireless communication already operates close to Shannon capacity and one of the most promising options to further increase data rates is to increase the communication bandwidth. Very high bandwidth channels are only available in the extremely high frequency part of the radio spectrum, the millimeter wave band (mm-wave). Upcoming communication technologies, such as IEEE 802.11ad, are already starting to exploit this part of the radio spectrum to achieve data rates of several GBit/s. However, communication at such high frequencies also suffers from high attenuation and signal absorption, often restricting communication to line-of-sight (LOS) scenarios and requiring the use of highly directional antennas. This in turn requires a radical rethinking of wireless network design. On the one hand side, such channels experience little interference, allowing for a high degree of spatial reuse and potentially simpler MAC and interference management mechanisms. On the other hand, such an environment is extremely dynamic and channels may appear and disappear over very short time intervals, in particular for mobile devices. It is essential to take these characteristics into account to turn a collection of such very high speed but brittle links into an efficient, low latency, and reliable network. This talk will highlight some of the challenges of and possible approaches for mm-wave networking.

      Bio: Joerg Widmer is Research Professor as well as Research Director of IMDEA Networks in Madrid, Spain. His research focuses on wireless networks, ranging from extremely high frequency millimeter-wave communication and MAC layer design to mobile network architectures. From 2005 to 2010, he was manager of the Ubiquitous Networking Research Group at DOCOMO Euro-Labs in Munich, Germany, leading several projects in the area of mobile and cellular networks. Before, he worked as post-doctoral researcher at EPFL, Switzerland on ultra-wide band communication and network coding. He was a visiting researcher at the International Computer Science Institute in Berkeley, USA, University College London, UK, and TU Darmstadt, Germany. Joerg Widmer authored more than 150 conference and journal papers and three IETF RFCs, and holds 13 patents. He serves or served on the editorial board of IEEE Transactions on Mobile Computing, IEEE Transactions on Communications, Elsevier Computer Networks and the program committees of several major conferences. He was awarded an ERC consolidator grant, the Friedrich Wilhelm Bessel Research Award of the Alexander von Humboldt Foundation, Mercator Fellowship of the German Research Foundation, a Spanish Ramon y Cajal grant, as well as seven best paper awards. He is senior member of IEEE and ACM.
