MON 09:00 - 12:30 T1: Emerging Paradigm Changes in Data Center Management Technologies
Speaker: Yechia Yemini (YY), Prof Emeritus of Computer Science, Columbia University
Room: 103

Abstract


Data Centers are undergoing dramatic paradigm changes:  with traditional silo architectures, all but eliminated through virtualization; with the convergence of server/switch/storage (S3); with the shift from simple client-server computing to large scale cloud computing; with the shift in networks from Client-Server traffic to East-West communications; and with the rapid growth in massive big-data processing needs. These changes have been stretching traditional management technologies and operations beyond their useful boundaries. This tutorial reviews these fundamental data center technology changes, the challenges they present to operations management and emerging new solution technologies.


Outline

1. Strategic trends in data center technologies

  • Hardware: the Sever-Switch-Storage (S3) convergence
  • Network: the rise of East-West traffic technologies
  • Software infrastructures: SD* everything
  • Virtualization: from virtual machines to containers
  • The Cloudification of everything
  • The rise of big data
  • Scalability: the interplay of scale-out vs scale-up

2. Operations management and control challenges

  • The breakdown of manual/silo/static operations management
  • Challenges: from manual management to algorithmic control
  • The new convergence: intelligent workload management (IWM)
  • Emerging strategic management technologies

MON 14:00 - 17:30 T2: Network Function Virtualization: Perspectives, Reality and Challenges
Speakers: Cesar Marcondes (UFSCar) and Christian Rothenberg (Unicamp)
Room: 103

Abstract


Approximately one year after its creation, the concept Network Function Virtualization (NFV) has become prominent in telecommunication operators' technology update plans. It creates an opportunity to make telecommunication networks more innovative in a very short time. In addition, this success easily brought together more than 150 members in a new industry specification group within the European Telecommunication Standards Institute (ETSI). From discussions of concepts, to use cases, to proof of concepts from a number of telecom operators, in this tutorial, we present NFV and the current state of industry recommendations and standardized terminology that make the core of NFV, as well as, perspective, research challenges and enabling technologies. The NFV idea mainly consists of the consolidation of hardware-driven network appliances in a commoditized virtualized datacenter environment, where the network functions are virtualized in virtual machines or similar. There are several reasons to invest in NFV, the possibility of long-term reduced operational costs, easy to manage energy expenditure due to be easy to turn on or off virtual machines, and underlying servers on demand, a more scalable and dynamic approach to create and operate network services, and so on. It also can complement Software Defined Networks (SDN) in order to automate the orchestration and configuration of telecom networks.

 

In this tutorial, we will show a comprehensive view of Network Function Virtualization (NFV). From the motivation of how NFV came to be created, a clear overview of the main concepts, objectives and goals of NFV, the challenges that follow the future development and deployment of this in practice, for example, interoperability, automation, scalability, self-management, orchestration, resiliency and security. We will also present the benefits of this technology and the relationship with Software Defined Networks (SDN), how they complement each other. From the concepts, we will describe the NFV architecture, research challenges and proposals, all the use-cases proposed by NFV ISG at ETSI, and describe some Proof of Concepts in the works, such as CloudNFV and CloudBand. We finally conclude the tutorial, describing enabling technologies, on many layers, in the network / computing infrastructure, such as OpenStack Neutron, Intel DPDK, Vyatta router, ClickOS and other important changes in the infrastructure enabling NFV.


Potential Target


We seek to motivate and present this tutorial to the following target public: undergraduates, graduates, professors and researchers that may have the interest to develop projects and studies on Network Function Virtualization. The main pre-requisite of this tutorial is have a good understanding of basic computer network, equivalent to an undergraduate course, and also some basic notions of virtualization and cloud delivery models. In addition, we also identify that people from IT departments and network operations, may also have interest to deploy NFV and therefore, this could be a good opportunity for them to update in terms of perspectives, trends, concepts and real applications of NFV.

FRI 09:00 - 12:30 T3: Management of Future Networks: Issues and Opportunities in Information-Centric Networks
Speakers: Cedric Westphal, Huawei Innovations and University of California, Santa Cruz
Room: 103

Abstract


Future Internet Architectures (FIAs) in general, and Information Centric Networks (ICNs) in particular, have received a lot of attention as potential replacement for IP, in order to solve some of the problems encountered in the current Internet. These problems include mobility, security, and handling the explosion in bandwidth consumption. As computing and storage costs have dropped dramatically, it is now possible to support new networking paradigms which involve forwarding based upon names rather than IP addresses, and in-network caching for the data which traverses the network. But mostly, ICN architectures offer a content abstraction to manage the network, which is more fine-grained and versatile than the IP abstractions. In this tutorial, we look at Future Internet Architectures, and ICNs in particular, and examine how the new precepts of Information Centric Networks allow better network management: content naming, routing by name, content­based security, in­network caching. We survey content­based architectures and detail more carefully some current ICN architectures, including Van Jacobson’s CCN architecture, and Publish/Subscribe proposals such as NetInf and PURSUIT. We identify how these introduce new management issues, but also new opportunities, as well some research challenges to be solved by content centric networks and some potential applications.


Outline


This half-day tutorial focuses on on-going research work. The field of Future Internet Architecture, and ICN in particular, is still very much in flux, and the tutorial will describe work-in-progress. The tutorial will expand a previous tutorial, given at IEEE SACONET Conference in Paris, in June 2013 and at IEEE GLOBECOM, in Atlanta in December 2013, which presented the key concepts and ideas of the ICN FIAs, but will be updated to reflect the research work that has happened since then, and to reflect the emphasis on the management issues.

It will cover the following topics:

  • Introduction & Definitions of FIAs and ICNs
  • Enablers of ICNs
  • Addressing content by name: naming structure
  • Hierarchical naming, flat naming, self certifying names, self-verifying names
  • Management of routing in ICNs
  • Management of caching in ICNs
  • A few ICN proposals viewed through their management requirements
  • Directory systems, caching policies, content location resolution
  • CCN/NDN, NetInf, PURUIS, TRIAD, DONA, Content-Based Routing, FARA
  • How does SDN control plane help with ICN FIAs?
  • Management of resources in ICN
  • Traffic Engineering
  • Caching
  • Enhancement of applications, and video streaming in particular
  • Research directions
