Carrier SDN for Multi-layer Control: Savings and Services

Network operators today face significant operational challenges when it comes to provisioning services that span multiple networking layers. Network operations in traditional carrier environments are complex and involve both multiple vendor-specific management systems and operational support systems and processes that span multiple organizational boundaries. SDN with its concept of network programmability has the promise to speed provisioning in such environments. With the plethora of legacy systems and protocols in traditional carrier networks, however, a pragmatic SDN controller approach that is modular and encourages a multi-vendor controller environment is very appealing in comparison to monolithic controllers.

This webinar will present a proof of concept SDN framework that was developed using IETF's Application Based Network Operations (ABNO) approach to support the orchestration and provisioning of services across a multi-vendor, multi-layer IP/MPLS and optical transport network.

It will cover concepts relating to multi-layer SDN, including automating network and service provisioning, orchestration of multi-layer operations, ensuring a modular SDN control layer architecture, and associated enabling technologies, such as OpenFlow, NETCONF, REST, PCE, BGP-LS, and GMPLS.


What You Will Learn/Seminar Objectives

Hear industry experts provide their perspectives on Carrier SDN, including views from market leading optical and IP networking equipment vendors as well as a Tier 1 service provider’s view.

  • Learn about what kind of open architecture Telefonica is looking for from the SDN Control Layer, and what the ABNO SDN control layer architecture offers.
  • Hear from Telefonica how this approach can address existing operational challenges and how it can facilitate the development of new services such as Networking-as-a-Service (NaaS).
  • Gain an understanding about how Infinera's Intelligent Transport Network solution enhances multi-layer networking and how Infinera's Open Transport Switch (OTS) architecture helps operationalize multi-layer SDN.
  • Hear Juniper's views about SDN architecture, and how the SDN control layer, IP networking equipment, and programmable interfaces relat to each other.



  • Victor Lopez, Technology Specialist, Telefonica
  • Chris Liou, VP Network Strategy, Infinera
  • Dirk van den Borne, Solution Architect, Juniper


Who Should Attend

  • Network Planners for Optical transport and/or IP/MPLS
  • Network Architects, looking to maximize efficiency and utilization from the network
  • Network Operations managers/directors, particularly those with interest in simplifying provisioning in multi-vendor, multi-layer environments
  • Service provider product managers exploring new monetization schemes or differentiating networking services



  • Intermediate – basic knowledge of core networking is assumed, along with familiarity with networking protocols and control plane technologies.

Chris Liou is a Fellow and Vice President of Network Strategy at Infinera, where he focuses on transport network architectures and solutions for network, service, and content providers worldwide, as well as transport and multi-layer SDN strategy and planning. Previously, Chris has also served in the roles of Vice President of Product Planning and Vice President of Product Management at Infinera, where he oversaw all product management and technical marketing activities, including product planning and product lifecycle management. Previously, Chris was at Ciena where he served as Senior Director of Product Management and Marketing for core optical switching. He has previously held product management and marketing positions at StrataCom and Cisco, and systems architecture and engineering positions at Hewlett-Packard and Telcordia. Chris received his B.S.E. with high honors in Electrical Engineering and a certificate in Operations Research & Financial Engineering from Princeton University and an M.S. in Electrical Engineering and Computer Science from Stanford University.

Víctor López received the M.Sc. (Hons.) degree in telecommunications engineering from Universidad de Alcalá de Henares, Spain, in 2005 and the Ph.D. (Hons.) degree in computer science and telecommunications engineering from Universidad Autónoma de Madrid (UAM), Madrid, Spain, in 2009. The results of his Ph.D. thesis were awarded with the national COIT prize 2009 of the Telefónica foundation in networks and telecommunications systems.

In 2004, he joined Telefónica I+D as a Researcher, where he was involved in next generation networks for metro, core, and access. He was involved with several European Union projects (NOBEL, MUSE, MUPBED). In 2006, he joined the High-Performance Computing and Networking Research Group (UAM) as a Researcher in the ePhoton/One+ Network of Excellence. He worked as an Assistant Professor at UAM, where he was involved in optical metro-core projects (BONE, MAINS). In 2011, he joined Telefonica I+D as Technology specialist. He has co-authored more than 100 publications and contributed to IETF drafts. His research interests include the integration of Internet services over IP/MPLS and optical networks and control plane technologies (PCE, SDN, GMPLS).
Dirk van den Borne is working as a solution architect for IP/MPLS core routing and packet-optical integration at Juniper Networks. In this role he is working with tier-1 customers worldwide on their core network evolution.
Dirk previously worked at Nokia Siemens Networks, where he was responsible for the optical system performance of the DWDM portfolio. He obtained a Ph.D from the Eindhoven University of Technology, the Netherlands, during which he conducted research in robust optical modulation formats, coherent detection and equalization. Dirk has published over 100 peer-reviewed papers and holds several patents on optical transport. He lives in Munich, Germany.
