1 ETSI FUTURE Network SDN and NFV for Carriers MP Odini HP CMS CT Office April 2013

2 Challenges and Opportunities Reduce Capex/Opex Challenges Innovation at devices and OTT side Number of devices explode data and signaling traffic with unexpected peaks Single purpose elements inflexible with high ASICs development cost Revenue trends for Comms Service Providers and Network Equipment Providers force more cost reduction, operational efficiency Opportunities IP everywhere: BB/LTE, Core, Cloud LTE opportunity to re-engineer the network and IT with frontier blurring Cache, profile and inspect traffic more efficiently Virtualization and Cloud mature in the Data Center, SDN trend COTS servers now supporting Gb Ethernet data processing Flexibility Faster time to Money Single Software Env. Homogenous Network Save cost and reduce TTM for new services Technically starts now 2

6 What is SDN - an emerging software based network architecture Applications Network API Network OS Infrastructure SDN Model Control Plane Abstraction of control plane from forwarding hardware Network control plane as a centralized software program Centralized intelligence of network topology Dynamic and programmable network, interaction with applications Implemented via variety of methods including OpenFlow protocol Key Benefits Provides opportunity for rapid innovation in networking Use cases for all types of networks including Enterprise Campus, Service Provider, Cloud, Data Center Can enable simplified management through network virtualization 6

7 Use Case Summary Nb Name Description #1 Appliance Migration Migrate proprietary boxes to COTS servers, decouple Data & control plan, leverage SDN protocols, controllers, centralized controller for multiple data plane components etc #2 Traffic Steering Introduce SDN with controller to extract 1 st packets, tag flow and avoid having to redo this for all packets. Allow dynamic change #3 Content Delivery Traffic routing Allow dynamic traffic routing thanks to SDN controller and dynamic view of available NW resources #4 Virtual Core IMS Enhance Policy with tight integration with SDN controller to route traffic to virtual core IMS #5 Networking as a Service Extand IaaS with dynamic NW resource allocation and allow Telecom operators to offer this as a Service to external customers #6 Edge policy Enforcement Have a centralized control but distributed enforcement model for Security policies. #7 Cloud Bursting Burst from Private Cloud to Public Cloud and be able to orchestrate the dynamic secure network in the public cloud #8 Optimal Traffic Engineering Inter-DC WAN Ability to have a Stateful controller to more dynamically place flows in the network, to best utilize the network resources #9 Data Center Virtualization Ability to move workloads around from any server to any other server within a DC without limitations of the network addressing 7

8 Use Case #1: Appliance Migration migrate appliances to SDN applications Independent Software Vendors Message Router CDN Session Border Controller WAN Acceleration DPI Firewall Carrier Grade NAT Tester/QoE monitor Open Rest API SDN Controller SGSN/GGSN PE Router BRAS Classical Network Appliances RNC 8

9 Use Case #2: Traffic Steering cache Security Content Filtering Statistics cache Security Content Filtering Statistics input Classical Network output input SDN Network output Traffic Steering OpenFlow Controller API Traffic Steering Without SDN With SDN 9

10 Use Case #3: CDN (Content Delivery Network) Level One: The Control Plane DNS World IP Partition CDN Mng, Logger CDN & ISP Admin Portal CDN Mgt (Fault, Perf, Config) CDN Management routing API SDN Controller routing Level Two: The Regional service OSS Logger Topology Tracker DNS Content ID Database SDN Controller routing SDN Controller Level Three: The End points End Point local caching 10

11 Use Case #4: Virtualized IMS infrastructure traffic rerouted via SDN to virtualized IMS Core application Ex: M2M Ex: M2M device IMS Service #1 IMS Service #2 IMS Service #3 Mobile NW applications Virtual IMS SDN controllers Fixed SDN Switch SDN Cloud (virtual Data Center) 11 SDN network Traffic Control Policies Traffic

12 Use Case #5 : IMS Policy Use Case 12

13 Use Case #6: Edge Policy Enforcement Threat Management Center Reputation Information -Reputation(ganjahaze.com) == malware -Alert administrator 3 Controller 2 4 Core 1 Edge Distribution 13

14 Phased approach for service providers NFV-SDN Projects NFV-SDN Cloud Virtual Service Providers Introduce Openflow (switches and controller) Move point applications (ie DPI, PCEF, Cloud base station ) to SW based & Cloud solutions Singlepurpose elements Application Plane Control Plane Data Plane SaaS Services Applications Plane Control Plane Infrastructure Plane SaaS Services SP#5 Infrastructure Plane Control Plane SP#1 (fixed) SDN API Applications Plane SP#2 (mobile) SP#4 (SDN IaaS) SP#3 (SDN ASP)
