VPLS Network Infrastructure
Carrier-Grade Private Backbone Built for Voice Reliability
At Ringcent, our voice and messaging services are powered by a high-availability VPLS (Virtual Private LAN Service) backbone, engineered to deliver secure, low-latency, and predictable performance for wholesale VoIP traffic across global interconnect points. Our infrastructure is designed specifically for real-time communications, ensuring stable call quality, high uptime, and seamless scalability for enterprise and carrier partners.
What is VPLS?
VPLS (Virtual Private LAN Service) is a Layer-2 VPN technology that allows geographically distributed network sites to operate as if they are connected to the same Ethernet LAN.
Unlike public internet routing, VPLS enables a private, controlled transport layer that provides consistent performance—ideal for SIP trunking, DID services, and carrier-to-carrier VoIP traffic.
Why Ringcent Uses VPLS for Voice
Built for Low Latency and Voice Quality Voice traffic is highly sensitive to jitter, packet loss, and delay. Our VPLS network ensures:
- Stable routing paths across the backbone
- Consistent latency across major regions
- Minimal jitter for clean RTP streams
- Reduced call setup failures and signaling issues
This results in superior MOS scores and reliable audio quality even during peak traffic periods.
Fully Redundant Core Architecture
Always-On Carrier-Class Resilience Our network core is built with redundancy at every layer to eliminate single points of failure. Key design elements include:
- Multi-node VPLS mesh topology
- Redundant routing and switching infrastructure
- Multiple carrier handoffs at each POP
- Automatic failover and route convergence
- Real-time traffic balancing across core links
This allows Ringcent to maintain consistent service availability even during carrier outages or fiber disruptions.
Fully Redundant Core Architecture
Key telecom regions, enabling:
- Shorter media paths for lower delay
- Local interconnect access to carriers
- Optimized termination routing
- Higher call completion rates
Our VPLS backbone connects all POPs into a single private transport fabric, ensuring traffic remains within controlled routes rather than unpredictable public networks.
Strategically Located Points of Presence
Ringcent operates multiple Points of Presence (POPs) across
Secure Private Transport
Isolation from the Public Internet. Our VPLS infrastructure provides a closed transport environment where voice traffic remains isolated from internet congestion and routing instability. Security advantages include:
- Private Layer-2 segmentation
- Controlled interconnect access
- Reduced exposure to DDoS and route hijacks
- Strict traffic policy enforcement
This design ensures a trusted backbone for carrier-grade VoIP services.
Optimized for SIP and RTP Traffic
Purpose-Built for Real-Time Communications. Our infrastructure is engineered specifically for SIP signaling and RTP media transport with:
- QoS enforcement for voice prioritization
- SIP-aware routing optimization
- Dedicated VLAN segmentation for customer interconnects
- RTP monitoring and quality analytics
- SBC integration for session security and compliance
This allows Ringcent to support both high-volume wholesale voice and enterprise-grade SIP trunk deployments.
Proactive Detection and Fast Resolution Ringcent Network Operations Center continuously monitors the VPLS backbone and voice platform to ensure maximum stability and performance.
We actively track:
- Packet loss and jitter metrics
- Route convergence and failover performance
- Interconnect capacity and congestion trends
- SIP registration and call completion ratios
- POP-level alarms and latency thresholds
Our goal is not just uptime—it’s consistent voice quality at scale
