11 Unifying Cloud & Carrier Networks. Why? Today, rigid network control limits flexibility of service creation. Operators view: agility (velocity), flexibility (granularity), simplicity (automation), scalability (lower OPEX), integration (shareconomy) Users view: quality of experience, rapid provisioning of elastic services, ondemand SLA configuration & monitoring, Follow-me How to? Virtualization of networks and network functions (NFV) Programmability (services and nodes) Dynamic service chaining COTS node (universal node) Service Provider DevOPs 20/05/2014 FP7 SPARC & UNIFY Overview 11

12 Problem: Slow & rigid networking limiting flexibility for service creation Service related functionality Replacement and Configuration Configuration and Customization Programmability Distribution of service functionality Aggregation Core Home/ Enterprise network CPE Access Node IP Edge DataCenter 20/05/2014 FP7 SPARC & UNIFY Overview 12

13 Vision: Unified Production Environ. from Home Networks up to DCs Service related functionality Optimizing distribution of functions & state Flexible Service Programmability Distribution of service functionality Aggregation Core Home/ Enterprise network CPE Access NODE IP Edge DataCenter 20/05/2014 FP7 SPARC & UNIFY Overview 13

14 MOBILE Vision: Flexible, Automated Service Programmability. Open Hardware Unified Node CPU Service Programming, Orchestration & Optimization CPU Switch SDN CPU Storage Aggregation Core DC Service Provider DevOps 20/05/2014 FP7 SPARC & UNIFY Overview 14

15 Overview use case groups. UC group3: Invocate Dynamic Service Chains Multi-provider support Self-Service support for end-customers UC group2: Dynamic Service Chains Service graphs combining network functions Integration of existing and virtual network functions Abstraction allowing programmability UC group1: Infrastructure Virtualization Generic hardware based on standard x86 Instantiation of network functions Business customer Orchestration & Management Network Service / Application Network Device Service Provider Service Graph NF1 NF2 VNF3 VNF4 VNF4 Carrier Network Infrastructure Provider Server Cluster Data Center Residential customer 20/05/2014 FP7 SPARC & UNIFY Overview 15

16 Main Expected Outcomes Advanced use-cases of future combined network and cloud architectures Incl. carrier requirements with supporting techno-economic feasibility study Architectural framework of the Unified Production Environment Service abstraction model & associated domain specific service creation language Algorithms to automate, optimize & establish fine granular service chains Flexible placement and dynamic adjustment of service components Automation of operations and optimization of the infrastructure Advanced scheme for management and operation to cope with increased network/service agility and handle services end-to-end Universal node architecture based on x86 components & accelerators, focus on selected use cases & establish reference benchmarks Integrated prototype

17 Summary (or some more challenges ) Things are changing quite fast, difficult to keep track, evaluate Increasing use of IT/software challenges operators Split of monolithic/big software blocks into pieces imposes new questions and challenges What is the best type? How to describe capabilities and requirements? How to combine pieces into services? How to interwork with legacy? 20/05/2014 FP7 SPARC & UNIFY Overview 17
