  • 8. 8 8 Pre-NFV vL3CPE: lessons learnt
  • 9. 9 9 Lessons learnt vCPE is complex !! QoS, NAT, security ?? Engineering Our enterprise customers will not like it !! Product Management I can’t configure this service !! The process doesn’t work. Service Delivery I don’t know how to troubleshoot this service !! Service Operations Our inventory tool cannot represent a virtual CPE … IT I can’t design this service !! Presales Our customers will want a discount !!Sales

  • 17. 17 17 WAN SDN: what’s next ? •  DC Network virtualized, but WAN remains static •  Next step (research mode) to bring SDN to the WAN (L1/L2/L3) : WAN virtualisation –  Flexible connectivity –  Dynamic / On-demand connectivity attributes (BW, QoS profile) –  WAN Network abstraction (multi-vendor, multi-layer) –  In-life service-type change •  Both DC and non-DC WAN scenarios: –  Cloud Inter-DC (data & storage) –  Enterprise to DC (Public / Private Cloud) –  Enterprise to Enterprise Optical & Carrier Ethernet VPN •  WAN SDN overlay solutions seem current realistic approach (several models): –  OpenFlow (with transport extensions if needed) agents in WAN network devices: standard API for configuration, monitoring & configuration –  Alternative to manage OF agent at the SDN controller plus other classic protocols (SNMP, etc) –  Existing transport control planes available (RSVP-TE, GMPLS, etc) for overlay solutions –  A mixed set of models (Overlay/Hybrid/OSS-based) to be analysed
