Dedicated Internet Access (DIA)

Dedicated Internet Access, commonly referred to as DIA, is an enterprise Internet connectivity service that provides a customer with dedicated and guaranteed bandwidth.

Unlike shared Internet services, where multiple users compete for the same available network capacity, DIA reserves the contracted bandwidth for the individual business. This provides more stable speeds, predictable performance and lower exposure to congestion during peak usage periods.

Lancom DIA is delivered through Lancom’s proprietary backbone and is designed for organizations that depend on reliable connectivity for cloud applications, real-time collaboration, hosted services, customer-facing platforms and other mission-critical operations.

The main difference is how network capacity is allocated. Standard broadband and many business Internet services use shared infrastructure. Although the advertised speed may be high, actual performance can vary depending on network congestion and the activity of other users connected to the same service.

Dedicated Internet Access provides reserved bandwidth that remains available to the customer. This results in more consistent performance, lower latency and greater predictability for applications that cannot tolerate fluctuations in network quality.

DIA can also include enterprise features such as symmetric bandwidth, dual IPv4 and IPv6 support, proactive monitoring, redundant routes, smart traffic routing and integrated DDoS protection.

Lancom Dedicated Internet Access is available with bandwidth starting from 100 Mbps and scaling up to multi-10 Gbps capacities.

The appropriate connection speed depends on the organization’s number of users, locations, cloud workloads, hosted services and daily traffic patterns. Requirements such as large file transfers, cloud backups, video conferencing, Voice over IP, remote access and customer-facing applications should also be considered.

Because DIA is scalable, bandwidth can be increased as the organization grows or as additional services and workloads become dependent on the connection. Lancom’s team can assess current traffic requirements and recommend a suitable capacity with room for future expansion.

Yes. Lancom Dedicated Internet Access provides symmetric bandwidth, meaning that upload and download traffic can operate at the same contracted capacity.

This is important because modern businesses increasingly generate and upload large amounts of data instead of only downloading information. Cloud backups, video conferencing, remote collaboration, hosted applications, data synchronization and file transfers all depend on strong upload performance.

A symmetric connection helps prevent upload-intensive activities from becoming a bottleneck and provides more consistent performance for users, cloud systems and services hosted within the organization’s own infrastructure.

Lancom DIA is delivered through the company’s proprietary multi-gigabit backbone, providing greater control over network routing, capacity and performance.

Smart routing selects efficient network paths to reduce unnecessary hops, minimize congestion and support low-latency connectivity. The backbone also interconnects with Internet Exchanges, network service providers and international carriers, enabling optimized access to destinations in Greece and abroad.

Diverse, high-capacity network routes can provide additional redundancy if a primary path becomes unavailable. Combined with 24/7 proactive monitoring and enterprise-grade infrastructure, this architecture helps maintain service stability and reduce the risk of connectivity disruptions.

Yes. DDoS protection can be integrated with Lancom Dedicated Internet Access to help protect the availability of Internet-facing systems and services.

A Distributed Denial-of-Service attack attempts to overwhelm a network, website or application with large volumes of malicious traffic. Without appropriate protection, legitimate users may experience severe delays or lose access to the affected service entirely.

Integrated DDoS protection helps identify suspicious traffic patterns and filter malicious traffic before it disrupts business operations. It is particularly relevant for organizations operating e-commerce platforms, customer portals, online applications, hosted infrastructure or other services that must remain continuously accessible.
