SD-WAN : The Next Evolution for Your Business

Legacy WANs are Falling Short

Standard WAN architecture based on older, legacy technologies can prove a barrier to overcoming these issues. An outdated WAN can hold back your business and prevent it from delivering the optimal user experience for modern business applications. With mobile, server virtualization, and cloud services all shifting the way we work, enterprises with global presence are encountering three common challenges:
  • Dealing with applications hindered by expensive bandwidth
  • Tackling branch deployments delayed by IT complexity
  • Architectural issues with traditional WAN that is both static and private, inhibiting the migration to dynamic and public cloud environments.

Trends of SD-WAN at a Glance

Digital business transformation has increased  the urgency for transforming WANs. As enterprises continue to move applications to the cloud, networking architectures such as SD-WAN have become increasingly important to accommodate cloud-based applications.

With more software as a service (SaaS)-based applications in the cloud rather than residing in centralized data centers, data traffic patterns shift. Enterprises see the ramifications of moving to the cloud loud and clear. Cloud-based apps and services can create a drag on app performance, boosting bandwidth costs and increasing data latency. Traditional wide area networks (WANs) aren’t equipped to handle these new data flows.

SD-WAN has already begun to change how customers manage branch offices to increase resiliency combined with low latency and jitter. The model for achieving this with today’s SD-WAN tools is to place artificial intelligence at either side of a multi-connection WAN, then perform real-time analytics based on defined application-specific settings that indicate which data flows should have priority over others.

How will CypressTel SD-WAN Serve You?

The functionalities of SD-WAN are classified into 5 components, and service models are customizable according to customer’s IT capability and needs.


a vCPE resident on customer side to initiate or terminate secured (encrypted) SD-WAN tunnels over the underlay networks for implementing virtual network functions, and CypressTel operates and maintains the SD-WAN Edge as a part of our service.

SD-WAN Gateway

enabling sites connected to those linked via alternative VPN technologies, i.e., MPLS VPN, Ethernet, which does not require SD-WAN vCPE placed on each VPN site to interconnectivity.

SD-WAN Controller

providing device management for all gateway and edge vCPEs, including but not limited to, configuration & activation, IP address mgmt., and pushing down policies onto vCPEs and gateways.

Service Orchestrator

offering the service management of the SD-WAN service lifecycle, including service fulfilment, performance, control, assurance, usage, analytics, security and policies, i.e., being responsible for configuring the end-to-end service between vCPEs and gateways over one or more underlay WANs.

Web Portal

to interact with customer on service activation, billing platform, performance monitoring, service visualization. After the service activated, the portal communicates with Service Orchestrator for service modifications, i.e., setting up QoS, business policies, etc.

GNOC Service Support

a dedicated expert team backing your SD-WAN experience 7*24*365, ensuring our SLA to you on premium network connection, policy deployment, and device maintenance at CypressTel.

CypressTel Makes it Easy for Adoption of SD-WAN

Why CypressTel’s SD-WAN?

CypressTel’s technology is cloud-first, with a focus on simplicity and ease of deployment while simultaneously providing a rich set of capabilities and scale. These principles are what today’s customers demand.

Application Acceleration

SD‐WAN can achieve automation – traffic steering and gives organizations the ability to prioritize traffic. The key is providing managers with easy‐to‐use tools for setting priorities and utilizing multiple links with active-active capability and performance based routing for increased performance

Improved Business Agility

Rapid deployment of WAN services (such as bandwidth and firewall) to distributed branch operations without the need to send IT personnel on‐site. Bandwidth can be easily added with additional circuits or reduced as business requirements evolve.

Cost Reduction

Internet connectivity (including cable, DSL and ethernet) is widely available, quick to deploy and a fraction of the cost of equivalent MPLS circuits. SD‐WAN provides the benefits of reliable, secure WAN service at Internet price points.

Optimized Cloud Architecture

SD‐WAN eliminates the backhaul penalties of traditional MPLS networks and leverages the Internet to provide secure, high‐ performance connections from the branch to cloud. With SD‐WAN, remote users will see significant improvements in their experience when using the cloud/SaaS‐based applications.

Ease of Adoption and Management

A key benefit of SD‐WAN is that it makes deploying WAN services at the branch fast and simple. SD‐WAN solutions must be straightforward to deploy, and they leverage centralized provisioning to eliminate the need for trained personnel to visit remote sites.


With greater network control, segmented security policies and increased security measures are simpler to deploy, so that SD-WAN can protect branch users, connected devices, and application usage at all direct Internet access breakouts and all traffic across the WAN.
