Tech Tutorial by Vikram Dham: Let’s build MPLS router using SDN


We will start with MPLS 101 and then look into MPLS related OpenFlow actions. In the second half we will delve into RouteFlow architecture and extend it to enable Label Distribution Protocol (LDP) and MPLS routing. We will conclude with a mininet based test bed switching traffic using MPLS labels instead of IP addresses.

This will be a hands on workshop. VM Images for Virtual Box will be provided. Attendees are expected to bring their laptops loaded with Virtual Box.

Tech Talk by Tom Tofigh: NFV: Key Driver for Domain 2.0 initiative

For this event we will be hosting Tom Tofigh who will delve into Domain 2.0 concepts and architecture.


NFV and SDN are new ways of thinking about networks and services deployment.  Networks are becoming both the computer and the adaptive cross-layer network architecture that provide programmable NFV building blocks for service abstraction. The network is fundamentally responsible for processing massive amount of flows that extend beyond layers 1-3.

Tom will start his talk on AT&T Domain 2.0 objectives and how it will benefit the end users.  He will then elaborate on Domain 2.0 architecture concepts and needs from service providers perspectives.  Tom will conclude his talk with a few NFV application examples such as Big Data, M2M, Traffic Shifting and service-chaining models.

About Tom Tofigh

Tom Tofigh is currently a Principal Member of Technical Staff in the AT&T’s Domain 2.0 architecture and planning Labs at AT&T.  He has extensive experience that spans across many disciplines including emerging mobility networks, switches, enhanced protocols, cross layer design, smart devices and chips design.  Tom has been responsible for the planning and implementation of large-scale telecommunications equipment.  Some of the products Tom has introduced include innovative solutions for the mobile devices, switches, platforms and QoS mechanisms. Tom holds over 25 patents awarded and many more pending. Tom has taught computer and networking courses at George Washington University.

John Casey: High Performance OpenStack Networks & Raphael Rosa: RouteFlow & IXPs

For this event, we will be hosting John Casey who is the co-founder and CTO of CPLANE NETWORKS

Also joining us for this event is Raphael Vincent Rosa from RouteFlow who will talk about use of SDN routers in Internet eXchange Points (IXPs).


Talk 1

CPLANE NETWORKS: High Performance OpenStack Networks

OpenStack is HOT! No doubt about it. A recent survey by The New Stack and The Linux Foundation shows OpenStack as the most popular open source project ahead of other hot projects like Docker and KVM. OpenStack is now taking its rightful place as the open source cloud solution for enterprises and service providers.

To date OpenStack networking has not yet achieved the performance, scalability and reliability that many large enterprises demand. CPLANE NETWORKS solves that problem by delivering secure multi-tenant virtual networking that overcomes the limitations of the standard Neutron networking service. By making all networking services local to the compute node and achieving near line-rate throughput, CPLANE NETWORKS Dynamic Virtual Networks (DVN) delivers mega-scale networking for the most demanding application environments.

In this session John Casey will cover the basics of DVN and explain how CPLANE NETWORKS achieves “at scale” network performance within and across data centers.

About John Casey

John Casey has over 20 years of deep technology leadership. His proven success with a variety of technical leadership roles in Telecom, Enterprise and Government and in software design and development provide the foundation for the system architecture and engineering team.

Previously John led worldwide deployment teams for both IBM’s Software Group and Narus, Inc. His work in large scale, high performance system design at Transarc Labs and Walker Interactive Systems brings leadership to the CPLANE NETWORKS product suite.

Talk 2

RouteFlow & IXPs

This talk will discuss the architecture of RouteFlow which is a leading OpenFlow based virtual router. It will focus on the new projects based upon RouteFlow which are finding traction in Internet eXchange Points (IXPs) – Cardigan being one of the most popular one. Some common aspects of IXPS will be shown. The talk will conclude with a list of future projects and vision of SDN routing.

About Raphael Vincent Rosa

Raphael is a Communications Network Engineer. He finished his MS in Computer Science working with intra datacenter routing, contributing to open source SDN projects such as Ryu network controller and RouteFlow platform. Currently he is pursuing PhD research under the guidance of Dr. Christian Esteve Rothenburg with main interests in SDN and Distributed-NFV topics.

Tech Talk by Ben Pfaff: Open vSwitch – Part 2 & Tim Van Herck: SDN & NFV for WAN

It is no small feat to lead development of Open vSwitch, software responsible for bringing revolution in networking, software which spans across user & kernel space and used by numerous companies for building SDN/NV & NFV products. For this event, we will be hosting Ben Pfaff, one of the founding engineers of Open vSwitch. This is your chance to hear and meet him in person!

Also joining us for this event is Tim Van Herck from VeloCloud Networks who will talk about extending SDN & NFV to WAN


Talk 1
Open vSwitch – Part 2

A previous presentation in March 2013 covered the past, present, and predicted future of Open vSwitch.  This talk picks up where that one left off, covering improvements made in Open vSwitch since then, new directions for the coming year, and some related work of interest in the industry.

About Ben Pfaff (twitter: @Ben_Pfaff)

Ben joined Nicira as one of its first employees in 2007 after finishing his PhD at Stanford. Since then he has been working on what became OpenFlow and Open vSwitch. He also made some early contributions to the NOX controller. He has been involved with free software since about 1996, when he started work on GNU PSPP and joined the Debian project.

Talk 2

Extending SDN & NFV to WAN

This session will walk through the evolution in branch networking and how SDN & NFV principles can be applied to the enterprise WAN to achieve increased reliability and flexibility. It will also cover how to lower the associated operational expense of running a classic enterprise WAN and what industry trends are pressuring changes on the design of such networks.When applying SDN & NFV principles to the WAN, there will be a natural reduction in complexity of managing services and guaranteeing uptime of network connectivity.

About Tim Van Herck

Tim is the Director of Technology and founding member at VeloCloud Networks.He is responsible for building out a global network of Points of Presence to deliver virtual last mile service to enterprise branches. Prior to joining VeloCloud, Tim was a founding member of Aryaka Networks, which offers WAN Optimization as a service. Tim has been passionately following the leading edge of network virtualization and security solutions for the past 15 years. He holds a master’s degree in Industrial Engineering from the University of Antwerp, and is based in VeloCloud’s headquarters in Los Altos, CA.
