Dedicated Circuit Services for Global Enterprise Connectivity: IPLC, EPL & EoMPLS Pseudowire 

Dedicated Circuit Services from IPTP Networks are designed for organizations that require private, predictable, and SLA-backed connectivity between critical sites, data centers, cloud environments, and international offices. Unlike best-effort Internet connectivity, dedicated circuits reserve network capacity end-to-end, providing consistent performance, transparent traffic transport, and greater control over routing, latency, and operational risk.

Whether delivered as an International Private Leased Circuit (IPLC), Ethernet Private Line (EPL), or EoMPLS Pseudowire, each service is engineered for mission-critical workloads where security, bandwidth symmetry, low latency, and service transparency are essential. IPTP Networks combines global backbone reach, standards-based Ethernet service delivery, and carrier-grade acceptance testing to ensure every circuit is delivered with measurable performance, interoperability, and long-term reliability.

IPLC: International Private Leased Circuit

International Private Leased Circuit (IPLC) provides dedicated, point-to-point connectivity between countries, delivering the ultimate in control and predictability for international operations.

What It Does:

IPLC establishes exclusive, direct connections across international borders using dedicated fiber optic pathways. Your traffic never leaves a dedicated pipe from source to destination, ensuring maximum security and performance.

Key Features:

• Dedicated International Links: Direct connections between any two countries
• Sovereign Data: Guaranteed data sovereignty — no routing through third countries
• Premium SLAs: 99.99% uptime guarantees for mission-critical international operations
• Symmetric Bandwidth: Equal upload and download speeds for bi-directional applications
• Customs & Compliance: Meet data residency and sovereignty requirements

IPLC service is delivered in alignment with Metro Ethernet Forum (MEF) standards, specifically MEF 6.3 (Ethernet Services Definitions) and MEF 10.4 (Ethernet Services Attributes), which define the service as an E-Line (Ethernet Line Service) with point-to-point EVC (Ethernet Virtual Connection).

Key MEF-defined parameters applied to each IPLC circuit include:

• CIR (Committed Information Rate): Guaranteed minimum bandwidth contractually reserved end-to-end for the duration of the service
• CBS (Committed Burst Size): Permitted burst above CIR without traffic policing
• UNI (User Network Interface): Standardized physical and logical demarcation point at each customer site, defined per MEF 13
• EVC attributes: Frame Delay (FD), Frame Delay Variation (FDV), Frame Loss Ratio (FLR), and Availability — all measured and reported per MEF 10.4 and aligned with ITU-T Y.1731 performance monitoring

This ensures full interoperability with third-party carrier equipment and provides a standardized framework for SLA measurement and reporting across international boundaries.

Ideal For: Financial institutions, multinational corporations, and government agencies requiring secure international connectivity with guaranteed performance and data sovereignty.

EPL: Ethernet Private Line

Ethernet Private Line (EPL) delivers point-to-point Ethernet connectivity with carrier-grade performance and reliability. EPL provides the simplicity of Ethernet with the guarantees of a carrier service.

What It Does:

EPL establishes dedicated Ethernet circuits between two locations, providing transparent layer 2 connectivity. Your Ethernet traffic passes through with zero modification, enabling plug-and-play deployment of business applications.

Key Features:

• Native Ethernet Interface: Connect directly to your switches and routers via standard Ethernet
• Transparent Layer 2: Traffic passes unmodified through the carrier network
• Flexible Bandwidth: Choose from 1 Mbps to 100 Gbps per service
• Rapid Deployment: Simple configuration enables fast time-to-business
• Multi-protocol Support: Transport any protocol over native Ethernet

Ideal For: Organizations seeking simplicity and standardization, particularly those with existing Ethernet infrastructure who want carrier-grade guarantees without complex VPN configuration.

EoMPLS Pseudowire: Flexible Ethernet Over MPLS

Ethernet over MPLS (EoMPLS) Pseudowire technology encapsulates Ethernet frames within MPLS packets, combining Ethernet’s simplicity with MPLS’s traffic engineering capabilities and scalability.

What It Does:

EoMPLS creates virtual Ethernet circuits over the MPLS backbone, enabling flexible, scalable deployment of Ethernet services. This technology supports both port-based and VLAN-based pseudowires, accommodating diverse connectivity requirements.

Key Features:

• Flexible Deployment: Support for both port-mode and VLAN-based services
• MPLS Benefits: Leverage traffic engineering, QoS, and scalability of MPLS
• Simplified Management: Manage via familiar Ethernet interfaces
• High Efficiency: Multiplex numerous circuits over shared MPLS infrastructure
• Rapid Scaling: Add circuits without provisioning new physical connections

Ideal For: Service providers and enterprises requiring flexible, scalable Ethernet connectivity with the advanced traffic engineering capabilities of MPLS.

Service Transparency Acceptance Testing for IPLC, EPL & Pseudowire

For all transparent circuit services — including IPLC, EPL, and MPLS Pseudowire — IPTP Networks performs standardized acceptance testing at service delivery to confirm end-to-end transparency, end-to-end data circuit characteristics, and throughput in accordance with established RFC and ITU-T recommendations:

• RFC 2544 (Benchmarking Methodology for Network Interconnect Devices) and Y.1564 (Ethernet service activation test methodology): Used for Ethernet service turn-up testing, measuring throughput, latency, frame loss, and back-to-back frame burst capacity across the full range of frame sizes (64 to 9000 bytes). Results are provided to the customer as part of the service acceptance report.
• ITU-T G.826 (End-to-end error performance parameters for international constant bit rate paths): Defines acceptable error performance thresholds including Errored Second Ratio (ESR), Severely Errored Second Ratio (SESR), and Background Block Error Ratio (BBER) for high-speed digital paths. IPTP applies G.826 metrics when confirming BER compliance on IPLC circuits.
• ITU-T G.8021 / Y.1341 (Characteristics of Ethernet transport network equipment functional blocks): Referenced for OAM (Operations, Administration and Maintenance) functionality on Ethernet transparent services, enabling in-service performance monitoring of frame loss ratio (FLR), frame delay (FD), and frame delay variation (FDV).
• ITU-T Y.1731 (OAM functions and mechanisms for Ethernet-based networks): Applied for ongoing per-service performance monitoring after acceptance, providing continuous measurement of MEG-level KPIs on EPL and Pseudowire circuits.

Bit Error Rate (BER) target for all transparent services at acceptance is ≤ 1×10⁻¹², consistent with ITU-T G.826 allocations for international high-grade circuits. Customers receive a full BERT (Bit Error Rate Test) report and RFC 2544 benchmark results as part of service handover documentation.
