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.

Underlay – FAQs
An underlay is the physical internet or leased line connection at a business site that serves as foundation for all services running on top: cloud applications such as Microsoft 365, AWS or SAP, VoIP telephony, video conferencing, multi-site connectivity, backup, SD-WAN and SASE. The quality of the underlay significantly determines the performance, uptime and user experience of all applications running on top. A high-quality underlay is symmetric in upload and download, has a defined SLA and uses multiple parallel lines for resilience.
The most important underlay technologies are business fibre for highest bandwidth and performance, leased lines with dedicated SLA and symmetric bandwidth, SDSL as a copper-based variant for older sites or smaller bandwidths, wireless point-to-point as a fast alternative without civil works where line of sight exists, and LTE or 5G as backup or initial access in rural regions. In modern setups, several technologies are deliberately combined per site, for example fibre primary plus mobile backup, to maximise resilience and performance.
Through the SAVECALL procurement pool, businesses typically save up to 20 percent compared to directly negotiated conditions. We bundle the purchasing volume of over 1,400 clients against the carriers and check site-specifically which provider is available at which price. For larger setups with multi-site rollout or combined underlay mixes, savings potential is sometimes higher. We deliver a concrete savings indication within 5 working days of baseline analysis.
Costs depend strongly on bandwidth, technology and availability at the site. Business fibre with 100 Mbit/s symmetric starts at 100 to 250 euros monthly, 1 Gbit/s ranges from 400 to 1,500 euros. SDSL costs 200 to 600 euros depending on bandwidth. LTE or 5G as backup starts at 30 to 100 euros. Leased lines with dedicated SLA range from 500 to 4,000 euros depending on bandwidth. For critical sites, plan two lines from different carriers. Concrete pricing in the initial conversation.
Multiple underlays per site dramatically increase uptime. If one line fails, a second takes over, ideally from a different carrier and via a different technology. This covers carrier outages, civil works and local incidents. Classic combinations are fibre + LTE backup, dual fibre from different carriers or fibre + wireless point-to-point at critical sites. With SD-WAN or SASE setups, both lines can be used actively in parallel and available bandwidth can be doubled.
LTE and 5G are productive within days. SDSL is available in 4 to 8 weeks. Fibre typically takes 8 to 16 weeks depending on in-house wiring and possible civil works. For complex sites with permit procedures or building connection works, 4 to 9 months are realistic. For fast rollouts, we recommend LTE or 5G as initial connection, later supplemented or replaced by fibre. SAVECALL coordinates availability checks, ordering, construction phases and cutover end-to-end across all carriers.
