Colt's SDN/NFV Vision

  1. 1. Colt’s SDN/NFV Vision Javier Benitez, 5 November 2013 Network & Platform Strategy and Architecture © 2013 Colt Technology Services Group Limited. All rights reserved.
  2. 2. Agenda 1 2 Vision: IT & Network Integration 3 Strategy: Programmable Networks 4 Plan: SDN/NF Research & Developments 5 2 About Colt Summary
  3. 3. Colt – The Information Delivery Platform • 44,000km EU high capacity long distance network, 27,000 transatlantic • Connecting 22 countries, 39 metro networks and >150 cities • 20 data centres and 19,000 connected buildings • 500+ NNIs, customers in 77 countries • MEF / ONF / NFV Member 3
  4. 4. Vision: IT & Network Integration The integration of the network and IT platforms from the service, technology, system and process point of view to deliver an end to end integrated customer experience (the Information Delivery Platform). Network automation, virtualisation, elasticity and rapid innovation 4
  5. 5. Strategy: Programmable Networks • Networks have evolved into complex, inflexible, closed, proprietary and costly systems (very little change in the last 15 years) – Main reasons: lack of networking principles and abstractions (control plane), lack of open Network APIs • In contrast, computing is open, heavily built on abstractions, supporting cloud paradigm (automation, virtualisation, elasticity, on-demand) • SDN/Programmable Networks: IT & Network integration (computing paradigm for networking / application & network worlds to communicate) – ONF - Software-Defined Networking: data & control plane separation, standardisation of fundamental networking abstractions (Per-hop & Overlay) – IETF - Software-Driven Networking: focus on network APIs to allow applications and network to exchange information – NfV – Network Functions virtualisation: standard IT virtualisation technology to consolidate many network equipment types 5
  6. 6. Strategy: Programmable Networks • Networks have evolved into complex, inflexible, closed, proprietary and costly systems (very little change in the last 15 years) – Main reasons: Architecture lack of networking principles and abstractions (control plane), lack of open Network APIs • In contrast, computing is open, heavily built on abstractions, supporting cloud paradigm (automation, virtualisation, elasticity, on-demand) Ops Model • SDN/Programmable Networks: IT & Network integration (computing paradigm for networking / application & network worlds to communicate) – ONF - Software-Defined Networking: data & control plane separation, standardisation of fundamental networking abstractions (Per-hop & Overlay) – IETF - Software-Driven Networking: focus on network APIs And many to allow applications and network to exchange information more… Way we do – NfV – Network Functions virtualisation: standard IT virtualisation technology to business consolidate many network equipment types 6
  7. 7. Plan: Colt’s SDN/NFV Infrastructure Development DC Fabric & Network virtualisation (CCN) DC Fabric Network Functions Virtualisation (NFV) L3 CPE router virtualisation (PE based): NLI Project • OpenFlow DC Fabric evaluation (2012, not mature enough) DC Network virtualisation & Architecture: Pilot Completed • • SDN Overlay: L2-L4 DC Network Virtualisation & DC Architecture virtualisation of the L3 CPE functionality (Internet access / IPVPN) NFV**: • vL3CPE / vDC Appliances (FW/LB) / vControl Plane (BGP RR) WAN SDN Network (Optical/Ethernet/IP): WAN SDN (**) • • • 7 ** Research End to end WAN network abstraction & full automation in a multivendor, multi-layer environment Flexible connectivity, i.e., ability to dynamically / on-demand change the connectivity attributes of the service (BW, QoS profile, etc). Use cases: L1 Optical / L2-L3 Packet / Inter-DC
  8. 8. Use Case I: DC Network Virtualisation / Overlay Colt WAN Network L2/L3 PE L2/L3 Packet Network L2/L3 PE DC SDN Virtual Network Orchestration L1 Optical Network e.g., XMPP e.g., BGP, Propietary DC (GW) Leaf DC (GW) Leaf SDN Controller DC Spine DC Spine OF / OVSDB / XMPP DC Leaf VM VM Overlay Gateway VS VS VS VS VS Storage Colt Data Centre Physical Compute VS VS VS VS Network Virtualisation (L2-L4) Cloud Compute 8 DC Leaf VM VM VS VS Overlay Gateway VS Storage Cloud Compute Colt Data Centre Physical Compute
  9. 9. Use Case II : NFV Colt Data Centre Colt Data Centre DC Fabric DC Fabric VM VM Colt Node VM L2/L3 Packet Colt Node VM Virtual CPE NfV Virtual FW Virtual LB BGP RR Customer Customer DWDM Optical L2 L2 L3 INTERNET L1 9 Customer L1 L3
  10. 10. Use Case III: WAN SDN Overlay Business Orchestrator Provisioning (OpenFlow) - Set up circuit from X to Y with BW X Set up circuit from A to B With 1Gbps Bw NMS integration (API) SDN Controller Topology Export (JSON/XMPP): • Node, link, resource • MPLS/BGP/GMPLS, etc Legacy Ethernet NMS OTS WDM L2/L3 OTS L2/L3 A Explicit Provisioning OTS L2/L3 WDM OTS Implicit Provisioning (GMPLS) L2/L3 WDM L2/L3 Packet 10 OTS Optical L2 OTS WDM L2 NMS Provisioning L2 Legacy Ethernet L2 B
  11. 11. Example of external use cases (1) Bandwidth Quality of Service API Service Console and Dashboard (SCAD) Portal Eth/IPVPN New connections/ Bandwidth/QoS change/ In-life hybrid networking SDN controller WAN as a Service Optical/EPN/IP/DC fabric 11
  12. 12. Example of external use cases (2) Virtual appliance App Store SDN controller Virtualised Appliances and App Store VM VM VM VM EPN/IP/SDN Cloud services API (orchestrator) Elastic bandwidth for infrequent applications EPN/IP/SDN 12
  13. 13. Summary • SDN is (still) in its early days. Most of the work by ONF/IETF/NFV still to be done (long journey). Most SDN products not GA - dust will settle eventually • Carrier class OpenFlow switches not generally available in the market (2012). However, DC SDN overlay solutions are a reality (Pilot completed, vendor selected, deployment on-going in Colt) • SDN/Network Programmability fits extremely well with Colt’s strategy to deliver integrated IT & Network services to our customers – SDN is a key contributor to automation and orchestration/policy (faster delivery/change, more agility, better utilisation, standard services) • NFV and service chaining will change the way we deliver L3-L7 services even more – not just vCPE • Next initiatives: – NFV: L3 CPE/DC Appliances/BGP RR – WAN SDN: L1 Optical / L2-L3 Packet / Inter-DC – External use cases being discussed with key vendors 13
