MON 08:45 - 12:45 T1: Network-as-a-service: Software Defined Networking for Cloud
Speakers: Anilkumar Vishnio, Vijay Mann (IBM)
Room: Refter

Software Defined Networking (SDN) is an emerging architecture for computer networking that comprises of a programmable control plane that is physically separated from the data plane in a network switch runs on a standard server and communicates with the switches through a standard protocol such as OpenFlow. This separation allows users and administrators to program routing policies and rules using high level languages such as Java and Python, without knowing anything about the arcane CLI commands supported by network switches. SDN can bring enormous value to cloud by providing Network-as-a-Service. Among other things, SDN can enable policy based creation of virtual networks for cloud tenants that can have overlapping or identical network addresses and also provide services such as service replication and fail-over. In this tutorial, we will first give an overview of SDN and then describe several such use cases for the cloud. We will also describe the various challenges related to managagement aspects of SDN for Cloud. We will give an overview of OpenStack and OpenFlow integration and how this integration can drive innovation in the cloud.


  • Overview of SDN and OpenFlow
  • SDN use cases for the cloud
  • Challenges related to management aspects of SDN for Cloud
  • Overview of OpenStack and OpenFlow integration and describe some use cases
  • Demos/practice sessions for some of the above use cases using FloodLight, Mininet and OpenStack.

MON 13:45 - 17:45 T3: NETCONF and YANG
Speakers: Jan Lindblad (Tail-f)
Room: Persconferentiezaal

In 2002, IETF held a workshop to collect requirements from network operators to guide the IETFs focus on future work regarding network management [RFC3535]. Several operators expressed their opinion that the developments in the IETF did not address their requirements, especially for configuration management. The outcome of this was the design of NETCONF and YANG. The Network Configuration Protocol (NETCONF) provides operators and application developers with a standard framework and a set of standard Remote Procedure Call (RPC) methods to manipulate the configuration of a network device. YANG is a data modeling language used to model configuration and state data manipulated by the Network Configuration Protocol (NETCONF) protocol, NETCONF remote procedure calls, and NETCONF notifications. NETCONF and YANG together enable network wide configuration management and data-models for devices and services that allow for well-defined semantics and rendering of management and agents. The tutorial will be a straightforward technical explanation of the standards.


  • Standards background, motivation and history
  • NETCONF and YANG introduction
  • YANG overview and examples
  • NETCONF overview and examples
  • Demonstration
  • Current IETF Status

[RFC3535]:  J. Schoenwaelder, Overview of the 2002 IAB Network Management Workshop
[RFC6241]: R. Enns, Editor, Network Configuration Protocol (NETCONF)
[RFC6020]: M. Björklund, Editor, YANG - A Data Modeling Language for the Network Configuration Protocol (NETCONF)

FRI 08:45 - 12:45 T5: Practical Network Programming
Speakers: Michael Behringer, Joe Clarke, Bruno Klauser and Jason Pfeifer (Cisco Systems)
Room: Refter

Over the past years, substantial progress has been made in the industry adoption of embedded manageability technologies, network-embedded automation and network programmability. Implementations of network programming are emerging in multiple technology domains – and various self-management, software-defined and autonomic concepts have been validated in proof-of-concept and early production deployments. Hence it makes sense to share experience, compare findings, review current best practices and not only discuss open and upcoming questions among industry practitioners, but also with researchers in academia. In this session, the following main areas will be discussed from the perspective of industry practitioners:

  • Network Automation: Concepts and lessons learned from several years of steep increase in industry adoption of network-embedded manageability and automation. Review of technologies, current best practices as well as challenges going forward.
  • Autonomic Networking: Based on the groundwork laid by research and academia, early validation and adoption of autonomic networking concepts became a reality.
  • Network Programming: Seemingly contradicting to some, perceived complementary by others – software defined networking and network programming introduce new ways for operational procedures and business applications to interact with the network.

A combination of concept presentations, practical validation and case studies as well as hands-on labs will be used to disseminate and discuss current practice as well as early adoptions and emerging capabilities - from the perspective of Cisco individual contributors and based Cisco as well as standard network technology. Current and future work will be discussed, including open questions, interest areas for research collaboration as well as opportunities for practical validation of upcoming concepts.

FRI 08:45 - 12:45 T6: Management of the Internet of Things
Speakers: Juergen Schoenwaelder and Anuj Sehgal (Jacobs University)
Room: Rector Vermeylen

The Internet of Things is a vision of a world here physical objects are seamlessly integrated into today's global information network. While initially the focus was the identification of tagged objects, there is meanwhile a clear trend to integrate small embedded systems (often equipped with wireless interfaces) into physical objects. Studies predict up to 50 billion devices connected to the Internet by 2020. With such growth-rates in mind, one has to ask the question how the Internet of Things will be controlled and managed. While implicit self-management is an obvious goal, there are a number of scenarios where explicit management will be needed. This tutorial looks into the challenges and into new enabling technologies that likely play a major role in the Internet of Things and its management.
