Underlay – The basis of a stable IT infrastructure
Slow connections, outages or bottlenecks in the network can slow down business processes and cost productivity. A stable IT infrastructure is crucial for transferring data securely, quickly and reliably – between locations, clouds and applications.
A powerful underlay forms the foundation: it provides the physical and logical infrastructure that transports all data efficiently and thus ensures the stable operation of modern corporate networks.
In a nutshell:
- Physical & logical infrastructure as a foundation
- Secure & efficient data transport
- Connection of locations, clouds & applications
- Basis for modern network technologies
Problem:
Global network structures pose challenges: site availability, carrier selection, SLA management, cost control and performance assurance – all of which require strategic planning.
Solution:
A solid underlay base from SAVECALL allows modern network technologies such as SD-WAN to develop their full potential. The quality of the underlay significantly determines the performance, security and scalability of the entire IT architecture.

Challenges of global Site Connectivity
The entire process, from the availability check to the obtaining offers to the selection of the right partnerties up valuable resources of internal teams. Companies with international locations often face the same problems:
Tight deadlines & inflexible carriers
- IT projects have fixed deadlines – carriers are often not so fast
- Delays mean project standstill and high additional costs
Check location availability abroad
- Requires countless inquiries to various carriers worldwide
- Checking offers for availability & compliance with requirements
Inconsistent SLAs & service quality
- Different bandwidths, latencies and response times depending on the region
- Inconsistent service quality, as each provider pursues different standards
- No single provider optimally covers all requirements worldwide
High administrative effort
- Numerous carriers, different time zones, many contacts – confusing and inefficient
- Local providers require regional contracts and often have no central control
- Difficulties in coordination, as each carrier has its own processes and SLAs
No German support
- Lack of German-speaking contacts makes communication difficult

SAVECALL’s recommendation
Internet
Glass fiber
Stand line
Dedicated Internet Access (DIA) is an exclusive, symmetrical Internet connection as your underlay network. Specially tailored to your company.
In contrast to shared Internet connections, DIA:
- Guaranteed bandwidths & low latencies
- Symmetrical upload and download speeds
- Greater reliability and service level agreements (SLAs)
- Better control and security
Companies with global locations benefit in particular from DIA, as it forms a stable basis for SD-WAN, hybrid networks and modern cloud infrastructures.
Further options for your underlay
Of course, there are many other options for your underlay network. SAVECALL provides you with network-agnostic, provider-neutral and free advice – and is your central point of contact.

Fast facts about the underlay
What is the difference between underlay and SD-WAN?
An underlay network is the physical infrastructure, consisting of hardware such as switches, routers and cabling, which enables data traffic between locations. data traffic between locations.
The overlay network, on the other hand, is a virtual layer that sits on top of the underlay and uses technologies such as SD-WAN to create virtual connections to improve network agility and management.
Why is the underlay critical to SD-WAN performance?
The underlay provides the basic infrastructure on which SD-WAN is built. Without a stable and powerful underlay, the benefits of SD-WAN – such as improved application performance and reliable connectivity – cannot be fully realized.
A weak underlay can lead to latency, packet loss and unreliable connections.
How can I ensure that my underlay is stable and efficient worldwide?
- Use network monitoring: Continuously monitor network performance to detect and fix problems early.
- Select reliable providers: Work with reputable carriers that operate in your desired regions.
- Implement redundancy: Use multiple connections and paths to ensure resilience.
How can I reduce my network costs with Savecall?
Savecall analyzes your current network infrastructure and identifies potential savings through:
Contract consolidation: consolidation of several contracts for better management and possible cost reduction and scalability of the entire IT architecture.
Use of technology: Modern technologies such as SD-WAN replace expensive MPLS connections and increase efficiency.
Optimization of the choice of provider: Selection of cost-efficient carriers that meet your performance requirements.
