Which communication service is best – and when?
In a world where connectivity is crucial for business operations, it can be difficult to know which communication service is the best fit. IP-VPN, EVPL, and DIA are three common alternatives – but what sets them apart, and how do you choose the right one for your company? To clarify these concepts, we've asked our CTO Tobias Jansson to explain the differences for us non-technical folks and provide guidance on which solution works best in different situations. Here's a quick and clear overview!
IP-VPN – Coordination for company offices
IP-VPN (Internet Protocol Virtual Private Network) enables a shared and secure connection for companies with operations in multiple locations. By integrating the company's network, employees can work as if they are in the same office, regardless of geographical location.
With IP-VPN, a dedicated virtual private network is created that connects multiple local networks. This means:
- Security: Communication flows through a protected, private connection, separated from the Internet.
- Efficiency: All devices and departments can communicate directly with each other without going through headquarters.
- Prioritization: Business-critical functions can be given priority in the network.
- Flexibility: Mobile employees connect easily via APN (Access Point Name) or mobile network.
IP-VPN is a scalable solution for optimizing business security, efficiency, and cost control.
EVPL – Point-to-point Ethernet Access
Ethernet Virtual Private Line (EVPL) is a capacity service primarily used by operators, system integrators, and IT resellers. This service connects networks point-to-point and is often used to:
- Link branch offices to headquarters.
- Connect end-user premises to the operator's point of presence.
Features and benefits:
- Dedicated bandwidth: Enables high-quality video conferences with good audio and video.
- Flexibility: All connections can use the same data system, regardless of geographic location.
- Foundation for IP-VPN: EVPL can serve as a base for building more advanced any-to-any solutions.
The dedicated bandwidth and point-to-point connection make EVPL ideal for companies requiring high stability and performance.
DIA – Dedicated Internet Access
Dedicated Internet Access (DIA) is a premium service for companies that need a secure and reliable internet connection. Unlike shared services, DIA offers exclusive bandwidth to a specific location or business.
Key benefits:
- Consistent performance: Speed and quality are not affected by other customers' usage.
- Optimal for cloud services: DIA guarantees consistent upload and download speeds, which is crucial for cloud-based applications and critical operations.
- Exclusive connection: The service functions as a private highway to the internet, without bottlenecks or traffic congestion.
DIA is particularly suitable for companies with high bandwidth and reliability requirements.
Wavelength Services (CWDM and DWDM)
DWDM is used to transport data over longer distances, and with high capacity, it becomes a preferred solution for operators and large enterprises.
Wavelength services use fiber optic technology to offer high capacity and fast data transfer. By converting electrical signals to light pulses in fiber optic cables, dedicated channels can be created for specific services or customers.
Technologies:
- CWDM (Coarse Wavelength Division Multiplexing): Uses fewer wavelengths and is cost-effective for shorter distances.
- DWDM (Dense Wavelength Division Multiplexing): Has denser wavelength spacing and can be amplified, making it suitable for long-distance transmissions.
Benefits of wavelength services:
- Typically up to 96 channels per fiber pair, with each channel up to 400 Gbps.
- Suitable for both point-to-point and large-scale network solutions.
- Efficient handling of large data volumes over long distances.
- Support for special protocols, e.g., fiber channel for connecting storage systems between data centers.
