1 SDN AND CLOUD Cloud SDN WHEN (BUZZ)WORDS COLLIDE Glenn Dasmalchi Global Enterprise CTO

2 GARTNER HYPE CYCLE Visibility? SDN?? Time Technology Trigger Peak of Inflated Expectations Trough of Disillusionment Slope of Enlightenment Plateau of Productivity

3 SDN IN A NUTSHELL Disaggregating the 4 Primary Network Functions, which enables: Choice of optimal processing platform for each function Ability to centralize functions End Result is Better Network Efficiency and Agility Network Element Management Management Control Centralized Control X86 (inc VMs) Services (L4-7) Forwarding Distributed Services (L4-7) Forwarding Silicon

4 SDN IMPLEMENTATIONS Original Focus Granular Control of Individual Network Elements Current Focus Control of Overlays over an IP Data Center Transport Centralized Node-by-Node SDN Controller e.g. OpenFlow PCE BGP-TE Centralized Edge Overlay a.k.a. Network Virtualization SDN Controller e.g. XMPP OVSDB Service Pool Copyright 2013 Juniper Netw orks, Inc. w ww.juniper.net

5 EDGE OVERLAY NETWORK VIRTUALIZATION FOR MULTIPLE TENANTS ON SHARED INFRASTRUCTURE Overlay Control Plane e.g. Juniper Contrail e.g. VMware(Nicira) NSX e.g. Hyper-V Network Virt On-Demand OverlayTunnels (e.g. VXLAN, NVGRE, STT, GRE) Physical Network Substrate Resulting Logical Networks

6 INTEGRATING WITH THE IaaS CLOUD STACK IaaS (i.e. compute and object storage services) OpenStack Cloud Controller (Orchestration) Quantum (Network-as-a-Service) Plug-in Compute Overlay Control Plane e.g. Juniper Contrail e.g. Nicira (VMware) NSX e.g. Hyper-V Network Virtualization Storage

7 A SIMPLE RESEARCH CLOUD BUT A LITTLE TOO SIMPLE University Data Center Copyright 2013 Juniper Netw orks, Inc. w ww.juniper.net

8 THE RESEARCH HYBRID CLOUD DCI with Seamless Federation of Resources Across DC s IP/MPLS VPN for Campus Connectivity with Service Levels Research Org DC Campus University Data Center Copyright 2013 Juniper Netw orks, Inc. w ww.juniper.net

9 BUT WAIT, WE VE SEEN THIS BEFORE Orchestrator DMI Network Management System (NMS) Config Node Analytics Node IBGP Route Reflector IBGP Route Reflector Control Node IBGP Control Node BGP SDN System To Other DC or L3 VPN XMPP VM VM CE PE P P PE MPLS over MPLS CE VM VM vrouter Underlay Switch Underlay Switch vrouter VM VM MPLS over GRE or VXLAN MPLS VPN Juniper Contrail (in the Data Center)

10 JUNOSV CONTRAIL SERVICE CHAINING Orchestrator SDN CONTROLLER REST SDN Controller Control Configuration Analytics Control Virtualized Server XMPP XMPP XMPP Virtualized Server VM VM VM IP underlay VM VM VM Service insertion based on policy. (supports both inter and intra-tenant) Virtualized Server Virtual Service Virtualized Server Virtual Service Overlay establishes a serial chain through multiple virtualized (or physical) network L4-7 services

11 VIRTUAL NETWORKS TO MINIMIZE COMPLEXITY Distributed Research Cloud NaaS (across geo s w/dci and VPN) CONTROLLER JunosV Contrail AUTOMATION & ORCHESTRATION Control Plane Control Plane Control Plane Standards-based architecture AUTOMATED,POLICY- BASED SERVICE CHAINING Dynamically deploy and scale services VIRTUAL NETWORKS PRJCT1 PRJCT2 PRJCT3 PHYSICAL NETWORK Switching Routing Security No forklift, investment protection Underlay Capabilities Matter

13 SDN and Cloud more like Thank You

14 JUNIPER S SDN STRATEGY: General Principles Separate Centralize Use the cloud Common Platform Standard Apply Broadly 4 Juniper Steps Centralize Management Extract Services Centralize Controller Optimize the Hardware 1 Licensing Model Full Use/Elastic JUNIPER SOFTWARE ADVANTAGE Transferable Software Lifetime Assurance
