The State of SDN & NFV: 5 Years In Neela Jacques, Executive Director, OpenDaylight @NeelaJacques

There is a Wave Sweeping the IT Industry

The Era of Standards Wars is Over

Collaboration With your team .but also with your competitors!

OpenDaylight Deployments are a Community Affair

Solutions Based on OpenDaylight

Open Collaboration

Successful OpenSource projects balance exploration and Balancing Innovation and standardization Standardization Exploration vs. Rationalization #odsummit

Open [Value] Platforms create large and diverse markets

Strong Desire for One Common Platform “Open Programmable Network” Supports a wide range of use cases (similar to Linux’s reach) Takes a modular/approach to architecture (deploy only what you need) Supports the full range of operator hardware (multiple southbound interfaces) Provides easy way to write once, work everywhere (service abstraction layer)

Over 2000 Participants World Wide! #odsummit

Vibrant Advisory Group #odsummit

Standardizing the SDN Platform Some Questions Have Been Addressed. Need to support multiple protocols YANG models While Others Still Remain: The role of policy / intent How to scale out logically centralized control Evolving role of OpenFlow How to measure end-to-end controller performance

ODL Platform: Broadest Set of Use Cases Automated Service Delivery Network Resource Optimization Visibility and Control Cloud and NFV Research, Education and Government

ODL Be: Automated Service Delivery Key Challenges: Instantiate new service to customer across multiple HW ODL Use Cases ODL Case Studies Telco enabling new subscribers AT&T Bandwidth on Demand Provisioning MEO satellite based communications to mining customers Serro Solutions Telstra Orange Large Hadron Collider (Caltech)

ODL Be: Network Resource Optimization Key Challenge: Exponential growth in traffic requirements and increased costs due to suboptimal network utilization efficiency. ODL Use Cases ODL Case Studies Rearranging Label Switched Paths KT Corporation Reconfiguring interior (e.g., OSPF) or exterior (e.g., BGP) routing protocols Orange Dynamically reprovisioning Carrier Ethernet Services (e.g., E-LAN) Adjusting OpenFlow forwarding rules Multilayer WAN controller (e.g. Ericsson) Tencent Tata Consultancy Services (TCS)

ODL Be: Visibility and Control Key Challenge: Provide single dashboard view and basic control of physical and physical network topology, configuration and performance ODL Use Cases Gather Network Statistics (e.g. SNMP /S-Flow data) across multi-vendor environment Monitor application performance (e.g. Skype for Business - Meru Network) ODL Case Studies Telefonica Brocade Flow Optimizer Tata Consultancy Services (TCS) Flow-Aware Real Time Analytics

ODL Be: Cloud and NFV Key Challenge: OpenStack Neutron by itself provides a tenant-facing cloud networking API but is limited what it exposes to cloud operators. NFV requires significant new functionality (e.g. Service Function Chaining) ODL Use Cases ODL Case Studies Network Virtualization for OpenStack China Mobile Multi-tenant Network Orange NFV Telco Services Massachusetts Open Cloud Policy and Intent OVS Virtualization for Software Switches SFC Support with a Virtualized Environment

ODL Be: Research, Education and Government Key Challenge: Flexible/Agile network that support new and future innovations ODL Use Cases ODL Case Studies High perf campus for research Cornell University SmartGrid/SmartCity City of Bristol, England Research w/ flow level control, Bandwidth on Demand SURFNet / GEANT

How AT&T is Leveraging OpenDaylight “AT&T open source is 5% of our code; our goal is to move to 50% by 2020.”—John Donovan, Senior Executive Vice President, AT&T Technology and Operations OpenDaylight powers AT&T’s Network on Demand Enterprise L2 Service in over 100 markets The company is leveraging OpenDaylight for its global SDN controller AT&T is contributing to a new ODL project to support YANG models: “We configure devices in our software-based network using a tool built on a data modeling language called YANG. We’ll submit our customized YANG design tool into open source through the OpenDaylight Community. Innovators will be able to create services that plug into our software-defined framework.” –John Donovan, AT&T 25

How AT&T is Leveraging OpenDaylight

Korea Telecom: T-SDN CHALLENGE: OPEX increase by segmented operations For E2E Service Configuration, many domain operators should participate Delayed service deployment because of manual planning and provisioning SOLUTION: Simplify and automate provisioning processes using TSDN #odsummit

Korea Telecom:T-SDN KT Architecture Adopted open source SDN controller (OpenDaylight Helium release) To reduce time and cost for development Integrated with legacy transport NMS Share inventory, topology and fault information Define YANG-model use in memory data store for fast path computation Real-time synchronization for resource changes Adopted MSPP, OXC, and PRN plugins #odsummit

NovoDC: An Example in Public/Private Cloud SDN Application (GUI & Orchestration) ④ response VM ID, vport VNFM VNFM VNFM NFV SDN ①Create vFW request ⑤send vFW information, classifier rules ②call plugin ③Create FW VM VIM(OpenStack) SDN Controller ⑥generate flow table DC Router SDN Service Chain VSW VM VSW VM Server Considerations & Observations vFW (S) VSW vFW (S) Server vFW (A) SDN GW vFW (A) Server Data Center VPC Service Chain are the basic services in both Public/Private Cloud Openstack is the integral part vSwitch performance improved; vFW, vLB ready for certain deployments #odsummit Service Chaining: multiple technologies including VxLAN extended/Openflow/NSH/other tags Internet

OpenDaylight in the WAN Objective: Self-provisioned dynamic network services What: Telstra PEN Platform Layer 2 Ethernet virtual cross connect (VXC) forwards frames between any 2 endpoints on the network How: MD-SAL application, leveraging OpenFlow protocol Reach: 25 POPs and growing #odsummit

How Tencent is Leveraging OpenDaylight CHALLENGE One of the largest web-scale companies in the world experienced low bandwidth usage of expensive WAN connections, low service redundancy scheduling efficiency SOLUTION Built DCI controller based on ODL achieved real bandwidth usage improvement network service quality enhancement #odsummit DCI Network Architecture

How Tencent is Leveraging OpenDaylight Why OpenDaylight? Great scalability of the architecture and extensible with rich southbound protocols / healthy ecosystem, resilient architecture, increasingly rich features and southbound protocols, clear version evolution rhythm and its reputation in the open source community “We request all our partners to be OpenDaylight compatible by end of 2015” #odsummit Marty Ma, Chief Architect

ODL Managing Satellite Networking CHALLENGE: Atypical data flows: weather, finance, airlines, government, energy -- mapping packet switch infrastructure to optical transport networks SOLUTION: Leverage ODL as a global controller to enable SDN on MEO satellite network, which provides consistent and ondemand connection #odsummit

How Caltech is Leveraging OpenDaylight Who: CalTech – Large Hadron Collider team What: Distribute 200 TB data beyond 13 Tier 1 sites to 160 Tier 2 research sites and 300 Tier 3 sites How: Controller based on ODL leveraging OpenFlow to setup up flow rules for data distribution. First based on Hydrogen, then Helium, soon to be on Lithium Quote: “ODL has become the De-Facto Standard Controller” #odsummit

How the City of Bristol is Leveraging OpenDaylight for Smart City / IoT Who: Bristol, England is building a fully programmable, citywide network using ODL What: Developing an open programmable city region How: An OpenDaylight-based SDN controller will integrate traffic across Bristol’s fiber optic network, LTE and experimental 5G wireless networks, and a mesh network of 1,500 connected lamp posts. NEC will provide equipment and support for the network’s radio elements
