IT and Network Integration – Colt’s Vision

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

IT and Network Integration – Colt’s Vision

A set of technical solutions •  to programmatically orchestrate the network •  to treat the network as a pool of resources •  to move network functions to the cloud •  to flex single or multiple parts of the network •  to direct traffic to specific locations •  to prioritize traffic intelligently (real time feedback)

Colt’s SDN / NfV current development L3 CPE

virtualisation (NLI)

L3 CPE router virtualisation: •  virtualisation of the L3 CPE functionality in the cloud

DC Fabric & Data Centre

Network virtualisation

(CCN)

DC Fabric •  DC Fabric evaluation

DC Network virtualisation: •  Virtual Network decoupled from physical hardware. •  VMs unrestricted placement and mobility. •  Dynamic network policies. •  Address Space virtualisation (VLAN/MAC). •  Network Virtual Services APIs •  Network Automation (APIs and orchestration)

WAN SDN (NLI / Mod

MSP)

WAN SDN Network (Optical / Ethernet / IP): •  WAN network virtualisation and automation •  End-to-end unified network abstraction allowing for true technology

layer and vendor integration.

Cloud Centric Networking (CCN) initiative Current DC network challenges

•  Logical Scale (VLANs, Tenant Networks) •  Stranded Capacity (Link waste, STP) •  Flexibility, Elasticity (complex dynamic connectivity) •  Port Density – limited 10Gbe •  Automation complexity •  TCO

Colt CCN goal research, pilot and deliver a new end to end DC network architecture blueprint combining best of breed network,

storage and compute capabilities to provide a holistic platform for current and next generation Data Centre and Cloud services

Summary

• SDN starting to mature but most SDN products not GA – needs continuous research. Plan for a 6 month development cycle, forget waterfall approach!

• Carrier class OpenFlow switches are not (yet) generally available in the market, however, SDN overlay solutions are a reality for the DC. But we still need to target full control and planes decoupling, SDN cannot be just augmentation!

• SDN fits extremely well with Colt’s strategy to deliver integrated IT and Network services to our customers

• Colt is actively deploying: – Modular Carrier Ethernet – Next-generation DC Fabric –  Integrated networks – And SDN is what will glue them together to offer an end-to-end experience
