Title: SDN Principles in a Cisco ACI and how Docker and LXC integrates in Cisco ACI environment

Abstract: The rise of Docker, Linux containers and micro-service architectures creates a tremendous set of opportunities for innovation. The Application Teams quickly adopted the technology and pushing it to new limits using agile development, continuous integration and continuous deployment. We’re excited about new Linux Container network concepts, which are critical to Cisco regarding the integration in the policy based network environment. We will talk about the SDN principles in the Cisco Application Centric Infrastructure and how Docker and LXC integrates in a Cisco ACI environment. This is the foundation of an environment that seamlessly integrates the infrastructure in DevOps driven application environments.

(2) 9:30-10:05 - Marcel Wiget & Christian Klewar, Juniper Net

Title: Docker with Openstack & OpenContrail for SDN

Abstract: OpenContrail is an open source and standards-based project for SDN controller that delivers network virtualization and enables the migration of applications and IT resources to more flexible private or hybrid cloud environments. A brief intro will show OpenContrail’s roots in MPLS based L3VPNs, followed by describing Orange Business Services public pilot based on OpenContrail, followed by an overview of using OpenContrail for Docker Containers, optionally with a demonstration. OpenContrail has been developed to work with the OpenStack cloud management platform and integrates with OpenStack as a provider to the Neutron networking as a service project. Focusing on simplifying OpenStack cloud deployment and management, OpenContrail aims to provide true end-to-end open source solutions for building scalable clouds. Docker networking support has been added to OpenContrail.

Coffee break – 10:15-10:25

(3) 10:25 - 11:00 - Emma Gordon, Project Calico & Metaswitch Networks, UK

Title: Project Calico - Simple, Secure and Scalable Networking for Data Centers

Abstract: We are still in the early days of providing suitable networking for data centers - facilities for networking between containers on different hosts are still in their infancy, and Docker networking is evolving with the addition of libnetwork. Security is also a big question - with many systems assuming that the data centre is an undifferentiated pool of resources, trying to carve this up into network tiers for security purposes is no longer an option.Noting that the vast majority of data center traffic is unicast IP-based, Project Calico opts to leverage standard Linux routing to offer a simple Layer 3 networking solution to handle the mainline case, whilst also allowing for other traffic types, such as multicast IP, and data center requirements such as overlapping IPv4 addresses. Calico offers a new security model where each instance of a micro-service is secured with per-workload network isolation (using iptables), distributing the network firewall to every host in the data center.After presenting an introduction to Calico, Emma will demo the latest integration with Docker/libnetwork.

(4) 11:10 - 11:45 - Mitchell Gusat, IBM Research Lab Zurich

Title: SDN and Monitoring for Cloud: An Endeavour Perspective

Abstract: In this talk IBM Research will present the latest developments from the Zurich Lab.Our focus is on SDN overlays, scalable high speed monitoring and heatmapping of datacenters with[masked]Gbps networks.

(5) 11:55 - 12:30 - Valon Mamudi, Irena Trajkovska, ICCLab, ZHAW

Title (Valon): OpenFlow based monitoring solution for Watchtower

Abstract: The growing number of datacenters calls for more sophisticated mechanisms on infrastructure management and optimization. To address this, SDN technology appears as a prominent solution on the top of the common networking principles in order to achieve better visibility and control on the datacenter network status and topology. In this brief talk, Valon will present his current research focus on Watchtower: an open source tool developed at the ICCLab for cloud incident management. The talk will tackle an OpenFlow use case for datacenter infrastructure monitoring to leverage Watchtower. It will additionally raise discussion on the current requirements for enhanced incident management solutions in a cloud datacenter environment.

Title (Irena): SDN-based SDK for DC Networks and Service Function Chaining Use Case

Abstract: The traditional networking protocols are not fully suited when applied to a datacenter environment. Applying SDN potentials in such scenario can improve resource usage, reliability, deployment and maintenance. To address the challenge of increased network complexity in datacenters, our goal is to develop a set of tools and libraries that exploit the power of SDN to enable cloud datacenter native networking.

In this talk we will present our current work on Netfloc (NETwork FLOws for Clouds): SDK for datacenter network programming. Netfloc creates abstractions of the underlying network and provides alternative libraries and flow patterns to the encapsulation protocols used in an OpenStack environment. Netfloc is organized in a set of OpenDaylight bundles and exposes REST API abstractions and Java interfaces for network programmers to enable optimal integration in cloud datacenters and fully SDN-enabled end-to-end management of OpenFlow enabled switches. We derive the SDK requirements based on real use cases and networking applications in the cloud. One such application that will be tackled in this talk, is Service Function Chaining.

Lunch - 12:40 - 13:45 @SWITCH Cafeteria

(6) 13:45 - 14:20 - Curt Beckmann, Brocade

Title: Advancing OpenFlow Interoperability with TTPs

Abstract: OpenFlow 1.0 offered limited functionality but good interoperability. Later versions of OpenFlow expanded capability at the cost of interoperability. The trade-off has its roots in the limitations of the original OpenFlow framework. Enhancements to the OpenFlow framework, called Table Type Patterns (TTPs), are providing an ability to offer the power of new features without sacrificing interoperability. This presentation will describe how the new framework is creating a bridge between OpenFlow 1.0 and next generation SDN concepts.

(7) 14:30 - 15:05 - Panagiotis Papadimitriou, University of Hannover, Germany

Title: MIDAS: Middlebox Discovery and Selection for On-Path Flow Processing

Abstract: The advent of routers with programmable processors can create opportunities for flow processing along the traffic path, obviating the need for traffic redirection to data-centers which can result in latency inflation. On-path processing requires the discovery of middleboxes that will be traversed by each flow and the assignment of network functions (NFs) to middleboxes, while preserving the order of the NFs as specified in the service chain.In this context, I will present MIDAS, an architecture for the coordination of middlebox discovery and selection across multiple NFPs on the traffic path. MIDAS relies on a centralized middlebox controller in each Network Function Provider (NFP) to provide interoperability among NFPs for flow processing setup. MIDAS establishes on-path processing via middlebox signaling, controller chaining, and Multi-Party Computation (MPC) based middlebox selection that preserves correctness and the confidentiality of NFP utilizations.

(8) 15:15 - 15:50 - Dr. Pedro A. Aranda Gutiérrez, Telefonica, Madrid Spain

Title: 5G Network & SDN - SUPERFLUIDITY project

Abstract: It’s an H2020 Project co-financed by the EU that has just started and its objective is to work an architecture that can cope with the requirements for 5G networks with regards to scalability, agility and the service levels expected for such networks. In my talk, I will explain the project objectives, put the project in perspective with the IETF/IRTF and other Standard Defining Organisations and propose how the SDNRG, in particular, could benefit from the project’s outcomes to steer future working directions.

Coffee break – 16:00 - 16:10

(9) 16:10 - 16:45 - Luke Gorrie, Snabb Co.

Title: Snabb Switch, Evolution today - its Design and Initial Use Cases

Abstract: Snabb Switch is a high-level open source software toolkit for building networking applications. The project is being adopted for a variety of products and uses within NFV, SDN, and more traditional areas. Snabb Switch was first presented at SWITCH in Zurich back in 2012. That was the very beginning of the project. This presentation will reintroduce Snabb Switch as it has evolved today and explain its design and initial use cases.

(10) 16:55-17:30 - Marco Canini, University Catholique de Louvain, Belgium

Title: Software-Defined Internet Exchange Points (SDXes)

Abstract: Software-Defined Internet Exchange Points (SDXes) promise to significantly increase the flexibility and function of interdomain traffic delivery on the Internet. Unfortunately, current SDX designs cannot yet achieve the scale required for large Internet exchange points (IXPs), which can host hundreds of participants exchanging traffic for hundreds of thousands of prefixes. Existing platforms are indeed too slow and inefficient to operate at this scale, typically requiring minutes to compile policies and millions of forwarding rules in the data plane.
In this talk, we present the design and implementation of iSDX, the first SDX architecture that can operate at the scale of the largest IXPs. We show that iSDX reduces both policy compilation time and forwarding table size by two orders of magnitude compared to current state-of-the-art SDX controllers. Our evaluation against a trace from one of the largest IXPs in the world found that iSDX can compile a realistic set of policies for 500 IXP participants in less than three seconds. iSDX is released as open source, complete with tutorials and documentation, and is already spurring early adoption in operational networks.
