A Survey of information-centric networking research
IEEE Communications Surveys and Tutorials, 2014Co-Authors: George Xylomenos, Christos Tsilopoulos, Xenofon Vasilakos, Nikos Fotiou, Christopher N. Ververidis, Konstantinos V. Katsaros, Vasilios A. Siris, George C PolyzosAbstract:The current Internet Architecture was founded upon a host-centric communication model, which was appropriate for coping with the needs of the early Internet users. Internet usage has evolved however, with most users mainly interested in accessing (vast amounts of) information, irrespective of its physical location. This paradigm shift in the usage model of the Internet, along with the pressing needs for, among others, better security and mobility support, has led researchers into considering a radical change to the Internet Architecture. In this direction, we have witnessed many research efforts investigating Information-Centric Networking (ICN) as a foundation upon which the Future Internet can be built. Our main aims in this survey are: (a) to identify the core functionalities of ICN Architectures, (b) to describe the key ICN proposals in a tutorial manner, highlighting the similarities and differences among them with respect to those core functionalities, and (c) to identify the key weaknesses of ICN proposals and to outline the main unresolved research challenges in this area of networking research.

Illustrating a publish-subscribe Internet Architecture
Telecommunication Systems, 2012Co-Authors: Nikos Fotiou, Dirk Trossen, George C PolyzosAbstract:The Publish-Subscribe Internet Routing Paradigm (PSIRP) project aims at developing and evaluating an information-centric Architecture for the future Internet. The ambition is to provide a new form of Internetworking which will offer the desired functionality, flexibility, and performance, but will also support availability, security, and mobility, as well as innovative applications and new market opportunities. This paper illustrates the high level Architecture developed in the PSIRP project, revealing its principles, core components, and basic operations through example usage scenarios. While the focus of this paper is specifically on the operations within the Architecture, the revelation of the workings through our use cases can also be considered relevant more generally for publish-subscribe Architectures.

caching and mobility support in a publish subscribe Internet Architecture
IEEE Communications Magazine, 2012Co-Authors: George Xylomenos, Christos Tsilopoulos, Xenofon Vasilakos, Vasilios A. Siris, George C PolyzosAbstract:The Internet is straining to meet demands that its design never anticipated, such as supporting billions of mobile devices and transporting huge amounts of multimedia content. The publish-subscribe Internet (PSI) Architecture, a clean slate information-centric networking approach to the future Internet, was designed to satisfy the current and emerging user demands for pervasive content delivery, which the Internet can no longer handle. This article provides an overview of the PSI Architecture, explaining its operation from bootstrapping to information delivery, focusing on its support for network layer caching and seamless mobility, which make PSI an excellent platform for ubiquitous information delivery.

inter domain routing with cut through switching for the mobilityfirst future Internet Architecture
International Conference on Communications, 2016Co-Authors: Adrian Lara, Byrav Ramamurthy, Shreyasee Mukherjee, Dipankar Raychaudhuri, K K RamakrishnanAbstract:Future Internet projects such as MobilityFirst and Named Data Networking have proposed novel mechanisms to replace the Internet Protocol to better support content delivery and mobility. However, the problem of efficient data transfer across the network core has not been adequately investigated. We tackle the challenge of inter-domain cut-through switching using software-defined networking (SDN). First, we propose and solve an optimization problem that minimizes the total transfer time using inter-domain tunnels. Second, we propose an SDN-based routing framework for the MobilityFirst Architecture capable of dynamically creating such tunnels. The main novelty of this framework is to name tunnels as network objects to simplify how tunnels are created and maintained. To validate our framework, we implement on the GENI (Global Environment for Network Innovations) testbed a prototype for the MobilityFirst Architecture. Our experiments with the optimization problem show that the inter-domain latency between controllers plays a key role on how tunnels are setup. Furthermore, our implementation experiments show that the control plane delay can be reduced by 75% when using inter-domain tunnels. Finally, we show how our framework needs fewer messages than current protocols such as label distribution protocol (LDP) to setup intra-domain and inter-domain tunnels.

Mobility-Centric Host Stack for the Future Internet
2015Co-Authors: Chunhui Zhang, Kiran Nagaraja, Dipankar Raychaudhuri, Ivan Seskar, Guanling Chen, Samuel NelsonAbstract:Abstract—The Internet is approaching a historic inflection point with online wireless and mobile devices to far surpass wireline devices. The current Internet Architecture and dominant protocols such as TCP/IP, which were designed and evolved on networks of fixed-hosts, are ill equipped for this fundamental shift. In this paper we introduce an alternative future Internet Architecture, MobilityFirst, that prioritizes mobility and trustworthiness. Specifically, we present the design of a novel host protocol stack and network API, which when working with MobilityFirst in-network services (incl. fast mobility tracking, multipoint delivery, in-network cache and computing) offers intrinsic support for host mobility, eases simultaneous access to multiple networks (multi-homing), and enables the content and context-centric applications. We present prototype implementations of the stack for Linux and Android platforms including a dual-home ready HTC EVO 4G(WiMAX)/WiFi smartphone. Early experiments demonstrate the ben-efits of our stack, including: 1) performance comparable or better than present Internet stack, and it allows devices to 2) opportunistically exploit multi-homing for better performance and robustness for data transfers under mobile scenarios.

MobilityFirst Future Internet Architecture Project
2013Co-Authors: Ivan Seskar, Kiran Nagaraja, Sam Nelson, Dipankar RaychaudhuriAbstract:Abstract —This short paper presents an overview of the MobilityFirst network Architecture, which is a clean-slate project being conducted as part of the NSF Future Internet Architecture (FIA) program. The proposed Architecture is intended to directly address the challenges of wireless access and mobility at scale, while also providing new multicast, anycast, multi-path and context-aware services needed for emerging mobile Internet application scenarios. Key protocol components of the proposed Architecture are: (a) separation of naming from addressing; (b) public key based self-certifying names (called globally unique identifiers or GUIDs) for network-attached objects; (c) global name resolution service (GNRS) for dynamic name-to-address binding; (d) delay-tolerant and storage-aware routing (GSTAR) capable of dealing with wireless link quality fluctuations and disconnections; (e) hop-by-hop transport of large protocol data units; and (f) location or context-aware services. The basic operations of a MobilityFirst router are outlined and a simple example of how the protocol supports dual-homing and multi-path is given. This is followed by a discussion of ongoing proof-of-concept prototyping and experimental evaluation efforts for the MobilityFirst protocol stack. In conclusion, a brief description of an ongoing multi-site experimental deployment of the MobilityFirst protocol stack on the GENI testbed is provided. Keywords- Future Internet Architecture, mobile networks, name resolution, storage-aware routing, GENI prototyping. I

network service abstractions for a mobility centric future Internet Architecture
Mobility in the Evolving Internet Architecture, 2013Co-Authors: Francesco Bronzino, Kiran Nagaraja, Ivan Seskar, Dipankar RaychaudhuriAbstract:The increasing composition of mobile devices and mobile applications in the Internet requires us to revisit the traditional principles of fixed, host-centric communications, when designing a next-generation Architecture. To support this major shift, we define in this paper a set of basic service abstractions that should be afforded by a future Internet that is centered upon the notion of self-certifying globally unique IDs (GUID) for all network principals - hosts, content, services, etc. alike. We followup with a specific set of network service APIs that provide full access to the proposed abstractions, and implement these on Linux and Android hosts that connect to an instantiation of the future Internet Architecture proposal - MobilityFirst [5]. Using performance benchmarks and the implementation of representative use cases we show that the API is flexible and can enable efficient and robust versions of present and future applications.

enabling vehicular networking in the mobilityfirst future Internet Architecture
World of Wireless Mobile and Multimedia Networks, 2013Co-Authors: Akash Baid, Shreyasee Mukherjee, Sandeep Mudigonda, Kiran Nagaraja, Junichiro Fukuyama, Dipankar RaychaudhuriAbstract:Vehicular networking, both vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I), is an increasingly important usage scenario for future mobile Internet services. Radio technologies such as 3G/4G and WAVE/802.11p now enable vehicles to communicate with each other and connect to the Internet, but there is still the lack of a unifying network protocol Architecture for delivery of services across both V2V and V2I modes. The MobilityFirst future Internet Architecture, discussed in this paper, is a clean-slate protocol design in which the requirements of untethered nodes and dynamically formed networks are considered from the ground-up, making it particularly suitable for vehicular applications. Here we describe the vehicular networking specific features and protocol design details of the Architecture and present evaluation results on performance and scalability.
