Named Data Networking (NDN) Project Newsletter for April/May 2017

The NDN project team compiles and publishes this newsletter periodically to inform the community about recent activities, technical news, meetings, publications, presentations, code releases, and upcoming events. You can find these newsletters posted on the Named Data Networking Project blog.

Community Outreach

• The NDN team will conduct a half-day SIGCOMM tutorial presenting an introduction to the architectural concepts, recent research results and remaining topics. For people interested in exploring more, the team will offer another half-day of activities for demonstrations of the NDN testbed and a set of NDN applications, introductions to the open-source codebase and code development, experimental tools, NDN emulator, mini-NDN, an NDN simulator, and discussions of future development. For more details, please see NDN Tutorial @ SIGCOMM 2017. To register for the tutorial, please see SIGCOMM 2017 registration site.

Technical News

•  The NDN Testbed has grown to 35 nodes with 96 links.  See the complete list of nodes and their status at the NDN Testbed page. You can see bandwidth on the testbed in real-time at the NDN Testbed Traffic Map.

NDN Publications, Presentations, and Technical Reports

• Hila Ben Abraham and Patrick Crowley. “Controlling strategy retransmissions in named data networking.” in proceedings of 2017 Symp. on Arch. for Networking and Communications Systems (ANCS 2017), May 2017. In this paper we study and decompose the core mechanisms of a forwarding strategy in NDN. We illustrate how the correctness of some NDN applications can be affected by the coupling between the application design and the strategy decision to retransmit an unsatisfied Interest.
• Jeff Burke, Peter Gusev, Zoe Sandoval, Jared J. Stein, and Zhehao Wang. “The Storytelling Systems of Los Atlantis.” in ACM SIGCHI Case Studies, May 2017. Los Atlantis was a multisite live performance created within a research effort exploring the simultaneous authorship of story and code.
• Hao Wu, Junxiao Shi, Yaxuan Wang, Yilun Wang, Gong Zhang, Yi Wang, Bin Liu, and Beichuan Zhang. “On Incremental Deployment of Named Data Networking in Local Area Networks” in ACM/IEEE Symposium on Architectures for Networking and Communication Systems (ANCS), May 2017. Assuming a local network with both NDN and IP traffic, we lay out three deployment scenarios: NDN-enabled hosts and all Ethernet switches, NDN-enabled hosts and all Dual-Stack switches (i.e., they can process both NDN and IP traffic), and a hybrid network with both Dual-Stack and Ethernet switches. We examine the technical issues involved in each scenario and propose solutions. In particular, in the hybrid scenario, we propose heuristics to optimize the placement of Dual-Stack switches.
• Haowei Yuan, Patrick Crowley, and Tian Song. “Enhancing Scalable Name-Based Forwarding” in proceedings of 2017 Symposium on Architecture for Networking and Communications Systems (ANCS 2017), May 2017. In this paper, our goal is to enhance name-based forwarding performance with memory- and time-efficient data structures. We first define the string differentiation problem, based on the behavior of speculative forwarding in core networks, and then propose fingerprint-based solutions for both trie-based and hash table-based data structures. We experimentally demonstrate that the proposed solutions reduce the lookup latency and memory requirements. The distributed forwarding scheme presented in this paper makes name-based forwarding truly scalable.
• Huichen Dai, Bin Liu, Haowei Yuan, Patrick Crowley, and Jianyuan Lu. “Analysis of Tandem PIT and CS with Non-Zero Download Delay” in proceedings of INFOCOM, May 2017.
• Minsheng Zhang, Vince Lehman, and Lan Wang. “Scalable Name-based Data Synchronization for Named Data Networking” in IEEE INFOCOM, May 2017. In this paper, we propose PSync to efficiently address different types of data synchronization. Names are used in PSync messages to carry producer’s latest namespace information and each consumer’s subscription information, which allows producers to maintain a single state for all consumers and enables consumers to synchronize with any producer that replicates the same data.
• Wentao Shang, Zhehao Wang, Alexander Afanasyev, Jeff Burke, and Lixia Zhang. “Breaking out of the Cloud: Local trust management and rendezvous in Named Data Networking of Things” in Proceedings of the 2nd ACM/IEEE International Conference on Internet-of-Things Design and Implementation (IoTDI), April 2017. This paper uses the design of an IoT-enabled home entertainment application, dubbed Flow, to demonstrate how the Named Data Networking (NDN) architecture enables cloud-independent IoT applications.
• Muktadir Chowdhury, Ashlesh Gawande, and Lan Wang. “Secure Information Sharing among Autonomous Vehicles” in Proceedings of the 2nd ACM/IEEE International Conference on Internet-of-Things Design and Implementation (IoTDI), April 2017. In this paper, we examine two potential threats, false data dissemination and vehicle tracking, in an NDN-based autonomous vehicular network.
• NDN TR-44 Revision 1: Klaus Schneider, Beichuan Zhang. “How to Establish Loop-Free Multipath Routes in Named Data Networking” shows that we can achieve a higher loop-free path choice than state-of-the-art loop-free routing protocols by combining an almost loop-free routing protocol (ALR) with loop-removal at the forwarding layer. ALR’s advantage comes from exploiting the ability of NDNs data plane to always exclude the incoming interface from forwarding, which broadens the routing task beyond the traditional goal of creating a Directed Acyclic Graph (DAG).
• NDN TR-48 Revision 1: Pedro de-las-Heras-Quiros, Eva M. Castro, Wentao Shang, Yingdi Yu, Spyridon Mastorakis, Alexander Afanasyev, Lixia Zhang. “The Design of RoundSync Protocol” In this report, we first use a simple case study to analyze the behavior of ChronoSync under simultaneous data publications, and then introduce RoundSync, a revision to ChronoSync to fix the overloading problem. RoundSync splits data publications into “rounds” and uses two separate Interest types for state inconsistency detection and update retrieval.
• NDN TR-50 Revision 1: Zhiyi Zhang, Yingdi Yu, Alex Afanasyev, Lixia Zhang. “NDN Certificate Management Protocol (NDNCERT)” enables automatic certificate management in NDN. In NDN, every entity should have corresponding identity (namespace) and the corresponding certificate for this namespace. Moreover, entities need simple mechanisms to manage sub-identities and their certificates. NDNCERT provides flexible mechanisms to request a certificate from a certificate authority (CA) and mechanisms to issue and manage certificates in the designated namespace.
• NDN TR-53 Revision 1: Wentao Shang, Yingdi Yu, Lijing Wang, Alexander Afanasyev, and Lixia Zhang. “A Survey of Distributed Dataset Synchronization in Named Data Networking” surveys sync protocols and highlights their commonalities and fundamental differences.
