long live the king!

The domain name leasedline.com was registered on 24th of July 1996.

At that time, there was no such complex technologies of today. The logic was very simple: a dedicated, point to point line to carry any type of traffic. No congestion, no jitter, nothing bad. The worst thing that could happen was a break on the cable and if you had a diverse protection of your main link that wouldn't be an issue for you. The history of leased lines actually dates back even more to the times when Alexander Graham Bell invented telephone. It was working on a line but not leased.

“In this experiment, made on the 9th of October, 1876, actual conversation, backwards and forwards, upon the same line, and by the same instruments reciprocally used, was successfully carried on for the first time upon a real line of miles in length.”

Frequently Asked Questions about Leased Lines
What is a leased line?
Leased Lines in Wholesale Data Transport

Leased Lines in Wholesale Data Transport

1. Definition

In wholesale data transport, a leased line is a dedicated, high-capacity transmission circuit provisioned between two specified points, providing guaranteed bandwidth and performance characteristics. It's an uncontended, symmetric connection leased by carriers to other service providers or large enterprise customers as part of a wholesale offering.

2. Differentiation from Other Connectivity Services

Service Type Key Differences from Leased Lines
Broadband
  • Shared infrastructure vs. dedicated connection
  • Asymmetric vs. symmetric bandwidth
  • Contended service vs. guaranteed capacity
  • "Best effort" vs. contractually guaranteed performance
  • Consumer/SME focus vs. carrier/enterprise grade
MPLS
  • MPLS is an overlay technology that can utilize leased lines as underlying transport
  • MPLS focuses on intelligent traffic routing and QoS across a network
  • Leased lines provide the raw connectivity on which MPLS services often run
  • MPLS typically connects multiple sites; leased lines are point-to-point
Dark Fiber
  • Dark fiber provides physical fiber without active equipment
  • Leased lines include the transmission equipment and management
  • Dark fiber requires customer to light and operate the connection
  • Leased lines offer specified bandwidth rather than unlimited potential capacity
Ethernet Services
  • Modern leased lines often use Ethernet as the interface protocol
  • Carrier Ethernet services represent an evolution of traditional leased lines
  • E-Line service is essentially the Ethernet version of a traditional leased line

3. Typical Use Cases

Carriers
  • Backbone connectivity between POPs (Points of Presence)
  • Middle-mile infrastructure connecting metropolitan networks
  • Backhaul from cell towers to mobile switching centers
  • International connectivity via submarine cable landing stations
  • Direct interconnection with peering partners at IXPs
ISPs
  • Transit connectivity to upstream providers
  • Backhaul from local access nodes to core network
  • Aggregation of traffic from multiple access locations
  • Interconnection with content delivery networks (CDNs)
  • Extension of network footprint into new territories
Large Enterprises
  • Data center interconnection (DCI) for business continuity
  • Private WAN connectivity between critical sites
  • High-capacity connections to cloud service providers
  • Support for latency-sensitive applications (financial trading, etc.)
  • Media broadcast and content distribution infrastructure

4. Key Benefits

Reliability
Carrier-grade leased lines deliver exceptional reliability with redundant equipment, protected fiber routes, and automatic failover mechanisms. Wholesale providers typically offer 99.99% or higher availability guarantees, essential for mission-critical transport services.
Dedicated Bandwidth
The hallmark of leased lines is uncontended, guaranteed bandwidth. Unlike shared services, a 10Gbps leased line delivers full 10Gbps capacity 24/7/365, regardless of other network traffic. This makes capacity planning predictable for wholesale customers.
Service Level Agreements
Wholesale leased lines come with rigorous SLAs covering multiple performance parameters:
  • Availability (typically 99.9% to 99.999%)
  • Mean Time to Repair (MTTR) - often 4-8 hours for major outages
  • Round-trip latency (with specific ms guarantees based on distance)
  • Packet loss (often guaranteed below 0.1%)
  • Jitter (typically below 5ms)
  • Provisioning timeframes
  • Financial penalties for non-compliance
Network Transparency
Leased lines provide a transparent pipe between endpoints, allowing wholesale customers to implement their own protocols, encryption, and traffic engineering without interference from the transport provider.

5. Technical and Commercial Considerations

Symmetric Speeds

Wholesale leased lines deliver identical bandwidth in both directions, critical for applications like data replication, content distribution, and two-way video transport. Common capacities in wholesale range from 1Gbps to 100Gbps, with 400Gbps becoming increasingly available in major markets.

Distance Limitations

Physical limitations affect leased line implementation:
  • Optical transmission limits requiring signal regeneration for long-haul routes
  • Inherent latency based on distance (approximately 5μs per kilometer)
  • "Fiber distance" vs. "route distance" considerations in network planning
  • Economic viability decreases with distance due to rising costs
  • Metro, regional, and long-haul circuits priced differently based on infrastructure requirements

Interface and Protocol Options

Modern wholesale leased lines offer flexibility in handoff options:
  • Ethernet (1/10/40/100/400GbE)
  • OTN (Optical Transport Network)
  • SDH/SONET (legacy)
  • Wavelength services (specific lambda on DWDM systems)
  • Grey or colored optics specifications

Pricing Models

Wholesale leased line pricing is structured around several factors:
  • Distance-based: Cost increases with circuit length, often with banded pricing
  • Capacity-based: Higher bandwidth commands premium pricing, though not linearly
  • Term discounts: Substantial reductions for multi-year commitments (3-5 years)
  • Volume discounts: Pricing advantages for wholesale customers committing to multiple circuits
  • On-net vs. off-net: Significantly different economics depending on existing infrastructure
  • Competition factors: Pricing varies dramatically based on route competitiveness
  • Installation charges: Non-recurring costs for circuit provisioning, especially if construction is required
  • Diversity premiums: Additional costs for physically diverse route protection

Regulatory Considerations

Wholesale leased lines navigate complex regulatory environments:
  • Regulated vs. unregulated markets affecting pricing freedom
  • Rights-of-way permissions for physical infrastructure
  • Cross-border connectivity regulations for international circuits
  • Construction permits and wayleave negotiations
  • Licensing requirements in certain territories
