Program Overview

NETSOFT 2015 – FOREWORDOn behalf of the Organizing and Technical Program Committees, we are pleased to welcome you to the inaugural conference on IEEE Network Softwarization (NetSoft 2015), in London, UK, April 13-17, 2015.

Since its inception in 2014, the IEEE SDN initiative, launched by the Future Directions Committee of IEEE, has recognized convergence between networking and IT as a major transformation which is going to impact Telecommunications and ICT industries. This trend, currently embodied by new paradigms like Software-Defined Networking (SDN), Network Function Virtualization (NFV), and Software-Defined Clouds, is expected to transform several other Industries that are increasingly using "softwarization" to optimize costs and processes and bringing new values to their infrastructures. Anticipating the importance of this new trend and its potential development in new environments, the IEEE SDN initiative felt the need to establish a flagship event that would address all stakes, challenges and solutions raised by these new paradigms.

Thanks to the involvement of a dedicated team, this first edition of the conference on network softwarization has been successfully established in less than a year with the main theme of bridging networking with IT and a particular focus on software-defined infrastructures for networks, clouds, IoT and services. A total of 108 papers were submitted in this area from all 5 continents. Each paper received at least 3 reviews with an average of 4.5 reviews per paper. Paper acceptance was thoroughly carried out during the technical program committee meeting held in Paris, France on February 20, 2015. Final selection includes 17 long papers for presentation during the plenary sessions and 31 short papers for presentation during the two parallel breakout sessions. In addition to the technical sessions, NetSoft 2015 also includes 3 keynote talks, 1 panel discussion, 7 software demonstrations, 3 tutorials and 3 workshops on 5G Soft Networks, Security in SDN, and Management of SDN respectively.

We are very pleased to offer such a high-quality technical program along with exciting some social events, including an impressive conference banquet in the Houses of Parliament.

We would like to thank all the people involved in the Organizing Committee and in the Technical Program Committee of this new IEEE conference for their dedication; University College London for kindly hosting this event; and the all Patrons for their financial support.

We are looking forward to meeting you in person at NetSoft 2015 in dynamic London.

KEYNOTESKeynote #1 Tuesday April 14, 2015 – 9:30-10:30

Where is NFV Pushing Current Boundaries?Speaker: Andy Reid, British Telecom, UK

Abstract: The basic idea of NFV is relatively straightforward: make use of high volume hardware from datacenters instead of custom hardware for the realization of the more the complex network functions needed by network operators. The early challenge was to achieve suitable packet throughput through standard datacenter servers but this is no longer a primary issue as a combination of the latest hardware features and developments in hypervisor and guest OS driver models have largely eliminated the performance bottlenecks. However, the real promise of NFV lies in service automation rather than purely in the hardware and here are still some significant challenges that undoubtedly push the boundaries of the current state of the art. Notable areas include service orchestration and lifecycle management, functional abstraction of a growing number of hardware and software “accelerations”, functional specification of automated configurable systems, and resource metrics for generic hosting functions. This paper discusses these areas and approaches that might lead to practical solutions for NFV.

Bio: Andy Reid is currently Chief Researcher, Network Services in British Telecom’s Research and Innovation Division and has been involved with NFV prior to the term being coined. He is responsible for developing BT’s architecture for NFV. As part of this he is a founding and active member of the ETSI NFV ISG. More recently he has become engaged with the EU FP7 and H2020 programs. In the past, he has had a variety of roles in network architecture and network and has had a particular interest in modeling. The modeling interest continues with a particular interest in functional modeling, information modelling, performance modelling as well as the economic modelling needed for regulation and competition law.

Keynote #2 Wednesday April 15, 2015 – 9:00-10:00

Applications Enablement on Software-Defined InfrastructuresSpeaker: Alberto Leon-Garcia, University of Toronto, Canada

Abstract: We envision future application platforms that are built on flexible, versatile and evolvable infrastructure that can readily deploy, maintain, and retire the large-scale, possibly short-lived, distributed applications that will be typical in the future applications marketplace. In this talk we discuss the design of such application platforms built on software-defined infrastructure (SDI).We begin by describing our view of SDI and the role of integrated control and management of converged heterogeneous resources. We motivate SDI in the context of a multi-tier cloud that includes massive-scale datacenters as well as smart converged network edges and virtualized access networks. SDI enables programmability of infrastructure by enabling the support of cloud-based applications, customized network functions, and hybrid combinations of these.

Next we introduce the NSERC Strategic Network for Smart Applications on Virtual Infrastructure, which is a national research network in Canada. We discuss SAVI’s investigation on the role of virtualization and SDI in future application platforms. We present SAVI’s testbed for a multi-tier computing cloud in which resources in the “Smart Edge” of the network play a crucial role in the delivery of low-latency and data-intensive applications. Resources in the Smart Edge are virtualized and managed using cloud computing principles, but these resources are more diverse than in conventional data centers, including programmable hardware, GPUs, and software-defined radio. We describe SAVI’s implementation of the Smart Edge and its integrated resource management system, and the deployment of a nationwide testbed. We present our work on the development of platform-

wide, adaptive resource-management and orchestration. We conclude with examples of applications that have been deployed on the SAVI testbed.

Bio: Professor Alberto Leon-Garcia is Distinguished Professor in Electrical and Computer Engineering at the University of Toronto. He is a Fellow of the Institute of Electronics an Electrical Engineering “For contributions to multiplexing and switching of integrated services traffic”. He is also a Fellow of the Engineering Institute of Canada and the American Association for the Advancement of Science. He has received the 2006 Thomas Eadie Medal from the Royal Society of Canada and the 2010 IEEE Canada A. G. L. McNaughton Gold Medal for his contributions to the area of communications. Professor Leon-Garcia is author of the leading textbooks: Probability and Random Processes for Electrical Engineering, and Communication Networks: Fundamental Concepts and Key Architecture. He is currently Scientific Director of the NSERC Strategic Network for Smart Applications on Virtual Infrastructures. He was founder and CTO of AcceLight Networks in Ottawa, Canada.

Keynote #3 Thursday April 16, 2015 – 9:00-10:00

Software-Defined Edge Objects in the Internet of ThingsSpeaker: Peter T. Kirstein, University College London, UK

Abstract: Traditionally Software Defined Networking (SDN) has been used to describe mechanisms that operate inside the core of the Internet. In the context of the Internet of Things (IoT), there is quite another use of the term. It can refer to the description of all the mechanisms needed to access the Digital Objects (DOs) that represent the physical devices at the edge of the networks. In the conventional Internet, one described only the address of devices at the network edge. The Domain Name Service (DNS) has been an excellent mechanism for this purpose; one could then assume that the object obeyed the protocols defined by the Internet Engineering Task Force (IETF). In the IoT, this is no longer adequate. The object can have very different properties dependent on the authorization of the entity requiring access. The differences are represented, of course, by the network address – but they may also be in the details that can be accessed through the network by a specific entity, and the authorization for various operations – including even recognizing the existence of the object. This talk describes how the use of Identifiers with an appropriate system of identifier storage, registration and identifier resolution can greatly extend the flexibility of a system dealing with IoT.

We will describe why we talk of DOs and not physical devices. We will describe also how this form of SDN is so appropriate to IoT, and allows the properties of the DO, the way it is accessed, and how its data is processed, to be described in a consistent manner. In the conventional Internet, the edge devices are invariant; they sometimes have more than one network address, but these are for very specific purposes. In IoT, they can be regarded as DOs with different identities depending on the Source DO. Of course this may result in radically different Network Addresses, but there may also be many profound consequences.

Bio: Professor Peter Kirstein is Professor of Computer Communications Systems at University College London. He is a fellow of a many professional bodies including the Royal Academy of Engineering, American Academy of Arts and Science, US National Academy of Engineering and British Computer Society. He has received many awards including the Commander of the British Empire, SIGCOMM, Postel, Lifetime Achievement of the Royal Academy of Engineering and Pioneer Member of the Internet Hall of Fame (awarded by the Internet Society – ISOC).

Peter has led many projects in computer networks, communications and applications – US, National and EC. Recently these have included IPv6 activities in public safety systems, videoconferencing, security, sensor networking and the Internet of Things. He led the Networking Work-packages in both U2010 and IoT6 and was the UCL PI for those projects.

Andy Reid, British Telecom, UKStefano Secci, UPMC-LIP6, FranceJames Won-Ki Hong, POSTECH, South KoreaFulvio Risso, Politecnico di Torino, Italy

Abstract: In the future, the border between infra-Consumers and infra-Providers will gradually disappear: more and more powerful Users’ smartphones, tablets, devices, intelligent machines, smart things…will become just like “network nodes”, storing large data-sets locally and even executing network functionalities and service component. “Softwarization” at the edge of current Telecommunications infrastructures and Internet of Things will merge in a sort of “continuum of logical resources”, spanning from the terminals, to the infrastructure nodes, up to the Cloud Computing.

These are the key questions you will be asked to elaborate:

• What are the potential synergies between the three domains: SDN-NFV, IoT and Cloud?• What will be the impacts on current value chains?• What are the technical challenges and the enabling technologies?

DEMOSDemo #1

An Integrated Environment for Open-Source Network Softwarization

Authors

Jong Hun Han, University of Cambridge, UKGianni Antichi, University of Cambridge, UKNoa Zilberman, University of Cambridge, UKCharalampos Rotsos, Lancaster University, UKAndrew W. Moore, University of Cambridge, UK

Abstract: Network softwarization drives innovation both in software and hardware. This demo introduces a highly integrated environment that enables open source solutions for soft-ware defined network (SDN) in both hardware and software. This environment is built upon the NetFPGA platform for rapid prototyping of networking devices. It showcases tools (OSNT and OFLOPS) for evaluating the performance of networking devices, and demonstrates them using a pipelined multi-table OpenFlow enabled switch application. An open-source environment integrating both software and hardware that fully inter-operate, as demonstrated here, is essential for high-quality software defined networking solutions

Demo #2

Authors

Jokin Garay, University of the Basque Country, SpainJon Matias, University of the Basque Country, SpainAlaitz Mendiola, University of the Basque Country, SpainJasone Astorga, University of the Basque Country, SpainEduardo Jacob, University of the Basque Country, Spain

Abstract: This demonstration focuses on the interaction between the service and the orchestrator, presenting an access control service which upon successful authentication and authorization triggers deployment of a new service for the authenticated user.

Demo #3

Extending Hadoop’s Yarn Scheduler Load Simulator with a Highly Realistic Network & Traffic Model

Authors

Philip Wette, University of Paderborn, GermanyArne Schwabe, University of Paderborn, GermanyMalte Splietker, University of Paderborn, GermanyHolger Karl, University of Paderborn, Germany

Abstract: NetSLS brings together MaxiNet, a highly scalable emulator for software-defined networks, and SLS, a simulator for benchmarking Hadoop Job schedulers.


16

The NetSLS demo shows how to emulate a whole cluster of Hadoop workers and the corresponding network infrastructure on only very few physical resources. This allows for testing novel job schedulers with a realistic network model as well as testing novel routing algorithms under realistic Hadoop workload.

With this work, the interdependency between the network and the jobs running on top of it can be included into the evaluation of new ideas, leveraging research on big-data applications with joint job and flow scheduling.

Demo #4

Abstract: The objective of the demonstration is to show two of the NetIDE framework benefits:

An Integrated Development Environment: one single tool to manage the whole life-cycle of Network Application: from the design, to the implementation, deployment and testing;

Network Application re-usability and portability: Network Applications written for many different controller frameworks, e.g. implemented in the past for different environments/needs, can be re-used and executed on top of the controller framework that is currently managing a given network infrastructure; or the other way around, a well-tested Network Application can be ported and executed “as is” on a second network controlled by another controller framework.

Abstract: The current device-centric protection model against security threats has serious limitations from the final user perspective – among others the necessity to keep each device updated with the latest security updates and the necessity to replicate all the security polices across all devices. In our model, the protection is decoupled from the users’ terminals and it is provided through a Trusted Virtual Domain (TVD) instantiated in future edge routers. The demo will show the architecture of a Network Edge Device (NED) augmented with a software that allows for the deployment of the user security applications in a trusted virtual domain; the demo will simulate a typical use case scenario,


17

with two user connecting to the NED, verifying its trustworthiness, authenticating and deploying the VMs enforcing their security policies.

Demo #6

Abstract: In this demo, we present the Virtual Network Controller (VNC) and the Multi-domain SDN Orchestrator. The VNC allows the deployment of OF-enabled multi-tenant Virtual Networks (VN). Once a requested VN is deployed, it is controlled with a customer SDN controller. The Multi-domain SDN Orchestrator is responsible for the provisioning of end-to-end paths across multi-technology network domains. The VNC interacts with the Multi-domain SDN Orchestrator to provision the requested virtual links.

Abstract: Several Network Operating Systems have been proposed in the last few years for Software Defined Networks; however, only a few of them are offering the resilience, scalability and high availability required for production environments. In our demonstration we present a geographically distributed SDN Control Plane, called ICONA, build on top of the Open Networking Operating System (ONOS) and designed to meet the aforementioned Service Providers requirements. During the demo, which runs inside the GEANT OpenFlow pan-European testbed, we show how a Service Provider engineer can easily manage and monitor the network and deploy some services and how ICONA can automatically recover from Control and Data planes failures.

TUTORIALSTutorial #1 Monday April 13, 2015 – 9:00-12:30

From dumb to smarter switches in software-defined networks: an overview of data plane evolution

Speakers:

Antonio Capone, Politecnico di Milano, ItalyCarmelo Cascone, Politecnico di Milano, Italy

Abstract: Coined in 2009, the term Software-Defined Networking (SDN) has gained significant momentum in the last years. SDN promises to enable easier and faster network innovation, by making networks programmable and more agile, and by centralizing and simplifying their control. Even if some SDN programmable networking ideas date back to the midle of the 90s, and are not nearly restricted to device-level programmability and to OpenFlow, it is fair to say that OpenFlow is the technology which brought SDN to the real world.

The separation between control and data plane is highlighted as a distinguishing feature of SDN, and sometimes even postulated as the SDN definition itself. But should such a separation necessarily take the form of a physical separation, namely a “smart” controller (or network of controlling entities), which runs the control logic for “dumb” switching fabrics? This was the case with the original OpenFlow, as its “match/action” programmatic abstraction necessarily resorts to an external controller for (reactively or proactively) updating forwarding policies in the switches’ flow tables.

Recently, the possibility of enriching the programmatic abstraction of OpenFlow to allow forwarding rules to evolve over time without directly involving the controller has emerged as a major trend in SDN research. This requires an evolution of the data plane that allows incorporating the ability to execute some kind of logic for reacting to events and modifying rules. This tutorial will discuss potential limits of SDN applications fully based on controllers and provide an overview of the trends in data plane evolutions analyzing advantages and potential risks. In the second part some application examples and hands-on activities will be presented.

Tutorial #2 Monday April 13, 2015 – 14:00-17:30

Service Function Chaining in the context of SDN/NFV

Speaker:

Christian Jacquenet, Orange Labs, France

Abstract: The design and the delivery of network services often assume the invocation of various elementary functions, such as IP forwarding, network address translation, Deep Packet Inspection functions, etc. The ability to smartly combine these Service Functions (SF) depending on the nature of the service to be delivered is a promising opportunity that should help service providers in improving the efficiency of service delivery procedures, not to mention the ability to enforce service-specific traffic forwarding policies for the sake of optimized network resource usage and, ultimately, customer’s Quality of Experience. The dynamic enforcement of a SF-derived, adequate forwarding policy for packets entering a network that supports such advanced Service Functions has become a key challenge for operators and service providers. SF-inferred differentiated forwarding is ensured by tweaking the set of Service Functions. The emergence of Software-Defined Networking (SDN) and Network Function Virtualization (NFV) techniques will likely facilitate the ability to dynamically structure service function chains and enforce appropriate traffic forwarding policies accordingly. This tutorial will provide a detailed insight into SFC mechanics and how they can take advantage of SDN/NFV environments.

About the Tutorial Speaker

Christian Jacquenet graduated from the Ecole Nationale Supérieure de Physique de Marseille, a French school of engineers. He joined Orange in 1989, and he’s currently the Director of the Strategic Program Office for advanced IP networking within Orange Labs.

Open Source Networking

Speakers:

Noa Zilberman, University of Cambridge, UKGianni Antichi, University of Cambridge, UKCharalampos Rotsos, Lancaster University, UK

Abstract: The SDN paradigm and its predominant realization, the OpenFlow protocol, have gained rapidly a significant interest from the network community and the approach is currently being introduced in production environments. Nonetheless, deploying SDN functionality in a production network raises significant concerns regarding the performance impact.

The NetFPGA is an open platform enabling researchers and instructors to build high-performance, SDN-enabled networking systems. The NetFPGA is the de-facto experimental platform for line-rate implementations of network research and it has a family of boards, supporting from 1GE to 100GE.

This tutorial will provide an introduction to prototyping networking devices on the NetFPGA platform, and focus on the use of NetFPGA for performance evaluation of SDN. The tutorial will elaborate on the available frameworks for each layer (management, control, data plane) in the SDN organisation model and provide an in-depth presentation of a novel switch evaluation tool named OFLOPS-Turbo.
