At the core of large-scale telecommunications is the physical and logical network that carries the traffic. LANCK Telecom operates a global network built on a foundation of over 1,200 direct interconnections. This web of connections, spanning five continents, is the engine that handles more than four billion minutes of voice traffic annually.

The strategic placement of Points of Presence (PoPs) is critical. By establishing a physical presence in key data centres worldwide, the network minimizes the distance data must travel. This geographic diversity is not just about reach; it is a fundamental strategy for controlling the quality of real-time communications.

In wholesale voice and SMS, the goal is to pass traffic from one network to another as efficiently as possible. The standard internet routing approach often involves multiple 'hops,' where data passes through several intermediary networks to reach its destination. Each hop adds a potential point of failure and introduces delay.

LANCK's architecture is built on a '0-hop' routing logic. This means that for our interconnected partners, we establish a direct, private link. Traffic doesn't traverse the public internet or third-party networks. It flows straight from the partner's network to ours. This is the shortest possible path, eliminating the variables that degrade quality in multi-hop scenarios.

This direct architecture has a measurable impact on the three enemies of real-time communication: latency, packet loss, and jitter.

• Latency: The delay for a data packet to travel from source to destination. By taking the most direct route, 0-hop routing minimises this delay.
• Packet Loss: When data packets fail to reach their destination. Fewer network hops mean fewer potential points where packets can be dropped.
• Jitter: The variation in latency over time. A stable, direct connection provides a consistent delivery time for packets, leading to clearer voice calls and more reliable message delivery.

A global carrier network must be fluent in multiple languages of telecommunication. LANCK's infrastructure is designed to bridge the gap between legacy and modern systems. We handle traditional Time-Division Multiplexing (TDM) traffic, often carried over IP networks using protocols like Sigtran, as well as native IP-based signaling.

This versatility is managed through a suite of protocols:

• SIP (Session Initiation Protocol): The dominant standard for initiating, maintaining, and terminating real-time sessions that involve voice, video and messaging applications.
• H.323: An older, but still relevant, standard from the ITU-T for real-time multimedia communications over packet-based networks.
• Sigtran (Signaling Transport): A protocol suite that enables the transport of traditional PSTN signaling (like SS7) over IP networks. This is crucial for interconnecting with incumbent carriers.
• SMPP (Short Message Peer-to-Peer Protocol): The standard for exchanging SMS messages between messaging centres and external systems.

Underpinning this entire operation is a proprietary monitoring and routing management system. This platform provides real-time visibility into network performance, analysing metrics like latency and jitter for every potential route. It automatically reroutes traffic to ensure it always travels along the highest-quality path available, maintaining the stability required for carrier-grade services.

By combining a strategic physical presence with sophisticated routing logic, a global carrier network can effectively manage the complexities of modern telecommunications.
