1. CenturyLink® SD-WAN Customer Presentation
Increase application performance
Simplify network management
Optimize and improve visibility
The growing penetration of cloud-based applications and mobility is forcing enterprises to re-evaluate their networking strategies. With software-defined WAN, or SD-WAN, CIOs can now confidently consider hybrid WAN deployments that make the best of Internet (inexpensive and widely available) and MPLS (private and reliable) links.
SD-WAN utilizes intelligent, application-aware software to route traffic over the optimal network technology, based on business policies.
SD-WAN ensures optimal application performance irrespective of the underlying transport. Customers using SD-WAN can control branch-site routing polices remotely. The numerous benefits of SD-WAN have attracted significant interest from enterprises, especially from verticals with highly distributed branch locations (e.g., retail, healthcare, banking and financial services, education).

Additional Fact on SD-WAN from Gartner: Moves network functionality into a central controller and deploys simple devices on-site. This can reduce capital expenditure (CapEx) by up to 80%. This can also reduce operational complexity and thus OpEx costs by at least 30%. “By the end of 2019, 30% of Enterprises will use SD-WAN products in all their branches, up from less than 1% today” Gartner

3. Drivers for a More Efficient WAN
Internet of Things (IoT) will soon outstrip human users, requiring secure, simple connectivity
Increasing complexity to manage and support the (hybrid) WAN and Cloud in multiple locations (e.g., 25+ locations)
Exploding real-time, bandwidth intensive applications, increasing stress on network performance, increasing security needs
Increasing cost of existing remote location/branch equipment, especially during a refresh cycle
Increasing provisioning times and the need for enhanced branch availability/uptime
Limited or no IT personnel on-site in remote locations
Need to reduce overall IT budgets across the WAN
“I want a way to manage my network similar to how I manage applications. I want an approach that is proven, simplified and secured, and not just for cost savings.”

4. How CenturyLink Defines SD-WAN
PRIVATE NETWORK CONFIDENCE OVER ANY CONNECTION
TRADITIONAL WAN (2005)
“Smarts” Intrinsic to Network
SOFTWARE-DEFINED WAN (2016)
“Smarts” Independent of Network
SD-WAN utilizes intelligent, application-aware software to route traffic over the optimal network technology, based on business policies.
An enterprise network created, defined, and controlled by a central software platform that remotely configures and monitors physical and virtual customer premises equipment (CPE) connected by a mix of network technologies including Internet/Broadband, Wireless LTE, Ethernet Local Access, and MPLS.

DATA TRANSPORT
The SD-WAN architecture supports all enterprise applications including data, video, voice, Web apps, wireless/LTE access, security, hosting, cloud connections, workloads, etc. The functionality of SD-WAN is:
SD-WAN uses Software-Defined Networking principles to separate the data plane from the control plane in the WAN. It abstracts the underlying transport networks (MPLS, Ethernet, wireless, satellite), and shifts control intelligence from customer premises equipment (CPE) or edge devices into a centralized software-based controller. A graphical user interface (GUI)-based management platform enables network administrators to define application-specific business policies, which the controller translates into routing policies enforced in the edge devices.
SD-WAN functionality is enabled by deploying physical or virtual CPE at customer sites and in the service provider’s (network service provider, cloud service provider or a managed service provider) cloud. The vCPE is also commonly pre-packaged and available as an AWS or Azure instance from some vendors.
A virtual CPE or appliance is a pre-packaged software solution that runs on a standard hypervisor-based virtualization platform. The functionality of a virtual appliance should, in theory, match identically to its physical counterpart, which is also (in fact) software-based; and most providers of virtual appliances attempt to assure similar functionality and performance levels across their physical and virtual appliances.
Key characteristics of an SD-WAN solution include the following:
Enterprises can use a combination of transport services (MPLS, Internet, Wireless/LTE) to support the WAN.
SD-WAN functionality is delivered over an edge device (physical or virtual), which is a highly simplified (x86 based server, as opposed to proprietary hardware) plug-and-play device that comes with zero-touch provisioning capability. The edge devices aggregate various transport links, inspect the links at regular intervals, and update network status to the controller.
The controller uses the network intelligence received from the edge devices, and compares it with the input received from network administrators on quality of service (QoS) policies for various applications, to make routing decisions. Network administrators can define network QoS requirements—bandwidth, latency, jitter, packet loss—for specific applications, which the controller translates into routing policy for edge devices to choose the most optimal path for sending traffic.
An SD-WAN solution provides deep visibility and analytics of network performance characteristics via a graphical user interface (GUI) that simplifies network management.

15. Optimize Internet Access
USING SD-WAN TO OPTIMIZE NETWORK CAPACITY
SD-WAN Basic
Here, traffic bound for the Internet must cross the MPLS network first and pass through the firewall in the data center, where policies are applied, resulting in inefficient “hair pinning” of traffic
New! Security (policy) is applied at the branch location and public traffic connects directly to the Internet, reducing congestion on the MPLS network, thereby increasing efficiency
