  2. 2. 2 2 Agenda NFV & SDN Definition, Relationship & Status About Colt Colt Plan: SDN/NFV Developments Summary thoughts 1 2 3 4
  3. 3. 3 3 NFV Definition BRAS Firewall DPI CDN Tester/QoE monitor WAN Acceleration Message Router Radio/Fixed Access Network Nodes Carrier Grade NAT Session Border Controller PE Router SGSN/ GGSN • Fragmented non-commodity hardware • Physical install per appliance per site • Hardware development large barrier to entry for new vendors, constraining innovation & competition Classical Network Appliance Approach • Network Functions fully defined in SW (VNFs) • VNFs provided by independent software vendors • VNFs running on standard high-volume (COTS) servers, storage and switches • Benefits: Opex & Capex savings, better time to market Network Functions Virtualisation Approach VNF VNF VNF VNF Software Functions Standard Servers & Switches
  4. 4. 4 4 NFV & SDN Relationship Network Functions Virtualisation Approach VNF VNF VNF VNF Software Functions / COTS Servers Standard Switches NFV SDN Software-Defined Network Functions •Standard high-volume servers, storage & switches •In theory could run on top of any network technology (even non-SDN) •Network requirements: real-time dynamic provisioning, seamless control, openness Software-Defined Networking •Separation of control and data plane to accomplish: elasticity, on-demand, programmability and scalability •SDN ideal underlying network for NFV •Key SDN use cases: VNF Forwarding Graph (service chaining) and NFVIaaSA B
  5. 5. 5 5 Benefits of OpenFlow-Based SDN in the Context of NFV • OpenFlow provides dynamic, automated, open and multivendor networking connectivity • OpenFlow configures in a standard (and open) way both physical and virtual entities: key requirement for NFV • OpenFlow promotes decoupling of hardware and software, with industry openness and standards to accelerate innovation which correlate with NFV principles Server Hypervisor Server Hypervisor Server Hypervisor A B Network Device Network Device Network Device ONF Solution Brief: https://www.opennetworking.org/solution-brief-openflow-enabled-sdn-and-network-functions-virtualization

  8. 8. 8 8 Plan: Colt’s SDN/NFV Infrastructure Development DC Fabric & Network virtualisation (CCN) DC Fabric • OpenFlow DC Fabric evaluation (2012, not mature enough) DC Network virtualisation & Architecture: • SDN Overlay: L2-L4 DC Network Virtualisation & DC Architecture WAN SDN Live Feb’14 L3 CPE router virtualisation (PE based): NLI Project • virtualisation of the L3 CPE functionality (Internet access / IPVPN) NFV: Formal Evaluation & PoC in 2014 • vL3CPE / vDC Appliances (FW/LB) / vControl Plane (BGP RR) Live Nov’12 Network Functions Virtualisation (NFV)
  9. 9. 9 9 vL3CPE (Internet Access / IPVPN) - Definition Customer MSP / L2 CPE M-MSP (L2/L3) Gen 4 DC Compute Storage Physical Compute / Appliance IP/MPLS (Internet/IPVPN) Spine Leaf Leaf L3CPE • Traditional Managed L3 services (Internet Access and IPVPN ) delivered with dedicated L3 CPE router • vL3CPE means removing the L3 CPE router and delivering the functionality as Virtual network Functions (in software) • Several locations being considered for the vL3CPE VNF – Current Location: L3 PE – Main NFV target location: Colt DC (NFV Platform / SDN Overlay) – Optional location in some cities (e.g. without DC): Colt Node – Additional Optional location: L2 CPE (distributed NFV) vCPEvCPE vCPE vCPE vCPE vCPE vCPE

WAN SDN Live Nov’13
  11. 11. 11 11 Summary - SDN/NFV, an Operator Perspective • Reality check: SDN/NFV maturing, but still early days: – ONF / IETF / NFV / OpenSource core work still in progress (long journey). – Most products today not commercially available, some proprietary solutions • DC SDN overlay solutions are real (Pilot completed, vendor selected, live deployment Feb’14 in Colt) – But, too rapid evolving technology, some proprietary • Long term (3-5 year) key challenges for Operators: – How to manage installed base / legacy technologies (network & OSS) – How to avoid closed, vertically integrated architectures again – Critical need for network visibility/analytics tools for real carrier adoption – OpenSource vs Standarization: Carriers typically not used to OpenSource? – Business transformation challenges can’t be dismissed!
