Complex networks, increasing data volumes and distributed locations present IT departments with new challenges every day. Conventional WAN structures are often rigid, cost-intensive and difficult to control, especially when cloud services or remote workstations need to be integrated.

With SD-WAN from SAVECALL, your company network becomes intelligent, dynamic and adaptable. Central control, intelligent line utilization and maximum reliability ensure performance, transparency and cost control, across locations and in real time.

SD-WAN: Site Connectivity with a modern twist

SD-WAN architecture: Connection of company locations, data center, MPLS, Internet and cloud services such as AWS, Microsoft Azure, Google Cloud and VMware.

Important aspects for the security of Site Connectivity solutions:

Increase performance & reduce costs with SD-WAN:
SD-WAN improves the performance of WAN connections through application-aware routing, load balancing and policy-based path control. At the same time, you reduce OPEX (operating expenses) through automated network management and the use of commodity broadband.

More flexibility & scalability without proprietary hardware: Reduce dependency on legacy systems and static network architectures. SD-WAN enables multi-transport support (e.g. MPLS, LTE, DSL) and zero-touch provisioning (ZTP) for rapid scaling. Use overlay tunnels and redundancy mechanisms for maximum reliability.

Centralized network management & easy implementation: Benefit from cloud-orchestrated network control with end-to-end visibility and traffic shaping. Quality of Service (QoS) policies can be defined via a central orchestration engine, while Dynamic Path Selection ensures optimal performance.

Optimal integration of cloud services & applications: Connect IaaS and SaaS platforms efficiently through Direct Internet Access (DIA) and Secure Edge Connectivity. SD-WAN improves the stability of real-time applications such as VoIP or video conferencing through Forward Error Correction (FEC) and packet duplication.

The increasing dependence on centralized services and cloud-based applications is a common reason for using an SD-WAN solution. Setting up branch offices and subsidiaries is often very time-consuming and inefficient.

Consider a situation where a cloud-based application is used by a large number of people in dozens of locations. The task of setting up secure connections to all users is very time-consuming.

In contrast, an SD-WAN solution can make this possible in just a few minutes. The reason for this is the ability to access a central control and management function. SD-WAN makes it easy to set up secure connections on any type of network topology.

Software developers or external employees often need immediate access to development environments or cloud-based services.

Ensuring this often takes several days with conventional networks

With the use of SD-WAN, such access can be granted within minutes.

With SD-WAN, secure network connections can be set up much faster and more efficiently than with conventional WAN solutions. The key lies in the central control and management function, which enables simple and flexible network configuration.

SD-WAN has fundamentally changed the traditional provider market. In addition to established providers such as Deutsche Telekom, Colt, Plusnet and Vodafone, numerous new players have emerged. These are often in no way inferior to the big players, and some of them even impress with innovative user guidance and integration options.
That’s why it’s worth making a comparison:

Advantages of SD-WAN

Two traders negotiating at a table, faces not visible, focus on movement and atmosphere.

In order not to lose proximity to customers, many new branches and subsidiaries are often opened quite quickly.

Often, IT can no longer keep up with the provision of central services and network infrastructure.

With an outdated, static network infrastructure, each new branch requires a great deal of planning and implementation effort.

SD-WAN solutions contain options for eliminating these bottlenecks.

Advantages:

  • Flexibility and automation in deployment
  • Fast commissioning due to independence from ISPs
  • Standardization of security topics such as firewall and VPN

    The combination of these SD-WAN advantages enables a flexible response to new requirements and growth.

SD-WAN has shaken up the provider market. In addition to established providers such as Deutsche Telekom, Colt, Plusnet and Vodafone, many new players have emerged – often with innovative user guidance and better integration options.

A comparison is worthwhile – for several reasons:.

  • Overview of all SD-WAN providers
  • The SD-WAN hardware is designed to be installed using the “zero-touch” method. This means that a non-IT person can connect the SDWAN equipment. The configuration is then automatically transferred to the SDWAN equipment in accordance with the guidelines.
  • Simple integration of SAAS and cloud providers such as Microsoft or Amazon. These platforms can be accessed directly without having to make a detour via the head office
  • All settings and guidelines can be viewed and edited in a portal.

However, all the SD-WAN advantages mentioned above only come into play if costs can also be saved as a result

SD WAN solutions can help to better plan and adhere to the IT budget

  • A zero-touch rollout not only saves time and capacity, but also saves IT staff time-consuming travel
  • WAN upgrade costs can be contained. By using an SDWAN solution, you can find out whether the expensive MPLS infrastructure really needs to be expanded. Increasing the cheaper Internet line is often completely sufficient
  • Since all settings and guidelines are managed via one platform and one console, costs and licenses for conventional tools and hardware are eliminated.
  • In the past, specialists were needed for routing and security, but today this can be handled by one person.

Keep an eye on technological differences, costs & features

SD-WAN providers differ greatly in terms of price, usability, performance and additional options such as IP telephony. A structured comparison not only helps to find the best solution, but also often enables considerable cost savings compared to traditional WAN technologies.

Case Studies/Whitepaper – SD-WAN

Differences with SD-WAN

Two traders negotiating at a table, faces not visible, focus on movement and atmosphere.

SD-WAN variants and functionality


A software-defined WAN (SD-WAN) enables the intelligent distribution of data traffic:

Hybrid network:

  • Critical application -> MPLS
  • Non-critical data -> Internet (via secure tunnel)
  • Result: Relief of the MPLS bandwidth

Self-service platform:

  • Network functions such as router, firewall, WAN management etc. are pre-installed as software (NFV)
  • No long provider inquiries necessary


Three options for Site Connectivity:

Internet based

  • For small sites with non-critical applications
  • Cost-effective, simple implementation

MPLS based

  • Manage existing MPLS networks as an overlay
  • Stability + SD-WAN flexibility

Hybrid

  • Combination of MPLS and Internet
  • Large locations -> MPLS
  • Small locations/home office -> Internet
  • Flexible choice of provider
MPLS backbone: secure networking of company locations, home office, data center and Internet via a central MPLS network.
