Agenda Introduction Agenda Overview A Look Back What Is Network Virtualization? Why Do We Need It? Real World Use Cases That Matter Right Now Wrap-Up & Next Steps Q&A

Overview Forget “Next Gen” Let’s Focus on “This Gen” Conceptual

A Look Back

Digital Evolution Phase 1: Adopt Telephones are awesome! Man! My job making sure people can use the telephone is awesome! Heck ya they are! Let’s use the telephone all the time!

Digital Evolution Analog Telephone Switch Operator Phase 2: Scale Manual Request and Action Physical Capacity Limitation Requires Duplication of Identical Effort Prone to Error… see “Operator Error”

The Digital Lifecycle Phase 2: Scale Nothing against telephone operators … but there has got to be a better way… “It’s not the operators fault, we need to re-think the way we do this…” “There’s no way we can expect any single person or group of people to manually route all of the world’s phone calls…”

The Digital Lifecycle Phase 3: Evolve We still need operators. We still need physical infrastructure.

The Digital Lifecycle Phase 1: Adopt The Internet Is Super Cool! Ya it is! Ya it is! The Internet Is Super Cool! Ya it is! Ya it is! Our Job Making Sure People Can Use The Network Is Sweet! Ya, Dude! Super Sweet!

The Digital Lifecycle Analog Telephone Switch Operator Phase 2: Scale Aaaaaaaah! Analog Telephone Switch Operator Network Engineer Manual Request and Action Physical Capacity Limitation Requires Duplication of Identical Effort Prone to Error… see “Operator Error” That list look familiar?

The Digital Lifecycle Don’t Be These Guys… Phase 2: Scale Nothing against network engineers… but there has got to be a better way… Don’t Be These Guys…

The Digital Lifecycle this This Just like Phase 3: Evolve This wasn’t designed to handle these Just like this Wasn’t designed to handle these

What Is Network Virtualization?

What Is Network Virtualization How Did We Get Here? Technology Drivers 2014 Flash Back Standardized interoperability through standardized APIs Centralized control plane Programmatic Networking Network Virtualization Overlay Networking Controller based global routing across sites and clouds and vendors Standardized cross-vendor API and RPC On-Demand Network Virtualization API driven infrastructure Network-aware applications On-demand Network Function Virtualization Next generation QoS Enabling physical and virtual integration Application aware networks Orchestration and automation Multi-Cloud Capable WAN Supports an ecosystem of API-driven Applications, appliances and utilities Security at the speed of compute not the network

What Is Network Virtualization? Programmatic Networking Software Defined Networking Layer 2 and 3 Virtual Overlays Network Virtualization Virtual Networking Network Function Virtualization

What Is Network Virtualization? Scalable Automated Elastic Orchestrated Intelligent SDN NFV NV SD-WAN Programmatic Networking Virtual Network Appliances Overlay Networking All Of The Above NFV NFV SDN

What Is Network Virtualization? Attributes of a Virtualized Network Application Aware Centralized Configuration Distributed Control Decoupled Control and Data Plane Physical and Virtual Services Overlay Services

What Is Network Virtualization? L2VPN Network Overlay Spine and Leaf SDN NSX NV SDDC OTV ACI VXLAN NFV

Why Do We Need It?

Why Do We Need It? Pilot Controls: Take-off/Landing Flight plan Course Altitude Speed Aircraft Mechanics Obstacle avoidance

Why Do We Need It? ATC Controls: Take-off/Landing Flight plan Course Altitude Speed Pilot Controls: Aircraft Mechanics Obstacle avoidance The need for Air Traffic Controllers? Too many planes in the sky to let them all make their own decisions We can have more aircraft in the sky at once if they’re more accurately orchestrated Aircraft can’t see each other before it’s too late Reactive flying isn’t acceptable when you have 500 passengers Congestion avoidance

Why Do We Need It? Too many application dependencies to keep track of manually We can have more active traffic and applications if they’re more accurately orchestrated Stability requires consistency The need for agility mandates the need for automation Automation requires programmatic responses to changing conditions Reactive engineering isn’t acceptable when you have business critical applications Dynamic congestion avoidance, prioritization and security policies

Why Do We Need It? Automation in general Automation vs. Artificial Intelligence

Why Do We Need It? Automation vs. Artificial Intelligence Just like a router, switch, or firewall – You need to tell the robot which block to move just like you need to tell the infrastructure how to treat traffic.

Why Do We Need It? Automation vs. Artificial Intelligence In order to tell the robot which block to move, you need to know exactly where it is, where you want it moved and when.

Real World Use Cases That Matter Right Now

Real World Use Cases That Matter Right Now SD-WAN An Orchestra of SDN, NV and NFV Creating the Perfect Cloud Enabled WAN Architecture? Cloud Based Controllers SD-WAN Appliances

Real World Use Cases That Matter Right Now Customer Use Case Key points: SD-WAN Dynamic Routing Load Balancing Physical Network Edge Multi-VRF NetFlow QoS GRE and IPsec

Real World Use Cases That Matter Right Now Provider Use Case Technologies In Use SD-WAN SDN NV NFV VXLAN API

Next Steps Define a plan Encourage workshops and collaborative discussions Foster proof of concept efforts Start small Plan for scale
