OSS in the era of SDN and NFV: Evolution vs Revolution - What we can learn from Cloud Computing
- 1. OSS in the Era of SDN and NFV: Evolution vs Revolution What we can learn from Cloud Computing Malcolm Orr Senior Platform Architect @coltymalc 12 November 2015 1
- 2. News in Brief 2 • The PC officially died today Cloud Computing 2010 • What is cloud Computing? • Should you move your business into the cloud? • 10 benefits of cloud computing • ROI for cloud computing • The new age of cloud computing • The security challenges of Cloud • The PC officially died today SDN/NFV 2015 • The business case is king • Basics: the differences between SDN and NFV • The new IP • Overcoming security challenges on a NFV deployment • SDN & NFV : Dynamic Duo of next generation networks Self Service Near real-time Dynamic Topology Available through portal and APIs Supports value added services Performant
- 3. Not all OSS’s are equal 3 • Relatively static infrastructure • OSS focussed primarily on resource management • “Just enough” service management • Complex Design/Assign activities • Solution design required • Topology resides in network Network IP Access Transport OSS Service Management Service Activation Resource Management Service Monitoring BSS
- 4. • NFV and SDN components of existing/new network services • Public cloud services • Off-Net broadband access • SD WAN (off-net and on-net) • Key characteristic programmable = Dynamic New Network Services 4 4 Colt OSS Customer L2/L3 Packet DWDM Optical Network Fabric INTERNET L2 VNF VNF Virtual L3 CPE Colt NFV/SDN Location Colt Node Public Cloud On-Net L3 CTRL Off-Net vCPE vFW

- 13. Choreography and orchestration 13 Products ResourcesServices Colt OSS/BSS Choreography (dumb orchestration) Infrastructure Domain NFV Domain SDN Domains Physical Network Domains Cross Domain Configuration Repository Analytics Central Catalogue Abstraction Operational Orchestration Actions Resources Metrics Abstraction Service Model Service Discovery Operational Orchestration Actions Resources Metrics Abstraction Operational Orchestration Actions Resources Metrics Abstraction Operational Orchestration Actions Resources Metrics Abstraction
- 14. Evolution means 14 NFV/ SDN NFV/SDN is going to just be another casualty of OSS integration projects NFV/SDN based services will lose any form of agility or responsiveness It will be harder to support the hybrid IT cloud model most of our customers will embrace
- 15. Call to have a successful revolution Call to OSS/SDN/NFV Vendors and Open Source Developers 15 Make SDN/NFV products smarter and more focussed on the operational management of the service Agree on a declarative, common north bound abstraction model that allows us to simplify the OSS/BSS integration problem Help us simplify the OSS to deliver dynamic services Help us enhance our services using real-time analytics and continuous feedback not rules or offline analysis
