What is a Software-defined WAN?

...Applied to a Specific (Enterprise) Wide Area Network

Abstraction of Functions Control Plane Data Plane Management Plane

Network Infrastructure Applications

❖ It’s an overlay that runs on top of existing legacy MPLS/Ethernet VPNs ❖ Supports flexible branch connectivity ❖ Network changes, for example adding appliances, become centrally orchestrated by an abstract management plane

Choosing a SD-WAN Solution

5

Can you believe the hype? What are you trying to achieve? Who to buy from?

SLIDE 6

Versa Networks

6

❖ Table stakes SD-WAN - such as:

  • Intelligent path selection
  • Policy management
  • Zero touch deployment
  • Security e.g., IPsec VPN and firewalling

❖ Layered security – such as anti-virus/anti- malware, IDS/IPS and URL filtering ❖ Advanced features - such as carrier grade NAT, load balancing ❖ Support for WAN optimization - through service chaining

SLIDE 7

Viptela (is being acquired by Cisco)

7

❖Secure Extensible Network (SEN): A secured platform that helps customers deploy and manage network virtualization ❖ vSmart Cloud-based SDN Controller: Management of functions including routing, policy, security, segmentation, and authentication of devices

  • n the overlay network

About the acquisition of Viptela by Cisco: ‘The competitive impact will take a year or more to be realized, and will largely be determined based on Cisco’s integration strategy’ Mike Fratto, Research Director, GlobalData

VeloCloud

8

❖ Optimization is a Strength - Dynamic multi-path traffic

  • ptimization

❖ Access Agnostic - Exploiting multiple access links, mixing MPLS and Internet access ❖ Convenient Management Interface - Administrative portal for delivery via its gateways and CPE ❖ Cloud Gateways - VeloCloud has deployed gateways at major data center/public cloud locations

Silver Peak Systems

9

❖ High Performance: Management feature supports dynamic path control, data encryption and extensibility to service chain and to route services across the WAN ❖ WAN Optimization: Data de-duplication is applied to accelerate data and application traffic ❖ Boost What You Need: ‘Unity Boost’ performance pack is priced at $5 per Mbps/month and only applies to “boosted” traffic

Key Discussion Points

10

❖ Is SD-WAN an MPLS killer? Nope ❖ Is SD-WAN the future of WAN? Yup ❖ Should you worry about sending traffic

  • ver the public Internet? Hell yeah

❖Does SD-WAN gain agility and cost- savings by leveraging the public Internet? Maybe – beware the hidden costs

Conclusions

11

❖ SD-WANs complement IP/MPLS and Hybrid VPN ❖ Rapid turn-up for branch sites is the main sweet-spot ❖ The solution should deliver cost-effective and agile support for leveraging IaaS environments, with traffic optimization, path selection and robust layered security
