Lumen® CDN Mesh Delivery is an advanced implementation of the WebRTC standard that enables delivery of live and video on-demand (VOD) content across a meshed topology from a CDN and between end user devices.
Tier 1 broadcasters can access the following technology for live streams, catch-up TV, user generated content, as well as ad or subscription-based VOD content.

Security features
- Mesh network cryptographic integrity checks
- Domain whitelisting
- App secret key whitelisting
- Fully encrypted communications with the backend (HTTPS & WSS)
- DNA backend authentication and matching features
- Fully encrypted DTLS mesh network communications
DNA dashboard - Web GUI to monitor and control
- Monitor DNA vs CDN traffic in volume and throughput
- See number of concurrent users over time
- See details per stream and per platform
- QoS data: buffering ratio over time
Data API
- Basic Data API:
- DNA & CDN traffic over time
- Concurrent viewers over time
- Buffering ratio over time
- Top 100 streams in traffic, bandwidth and audience
Advanced data analysis
- Advanced Insights API (to be released in December) allowing multidimensional queries including:
- Platform
- Live & VOD
- Stream
- SiteId
- Country
- ISP
- Custom Efficiency Reports per customer upon request (paid service), accessing and compiling data from our Hadoop data pipeline
Dashboard real-time monitoring
- Real-time monitoring panel showing top streams with DNA vs. CDN efficiency and audience
Alerting and reporting
- Automatic reporting interface that can send daily, weekly and monthly reports on efficiency and traffic
- On-demand alerting service from our customer support if we detect anything unusual in different metrics: efficiency, audience, QoS, new release, etc.
Dashboard configuration
- Create properties to use different configuration options for different types of content (live vs. VoD, premium vs. free, etc.)
- SSAI detection
- Range request detection
- Wifi and cellular network upload and download configuration
- Activation Ratio feature for easy ramp-up and full control over the mesh network
- Activation threshold for VOD: activate the DNA plugin only on the most popular streams with more than 3 active users in the last 20 minutes
Client-side configuration and API
- Configuration: ContentId, asynchronous loading, siteId for DNA Enterprise
- Client API:
- Per-user traffic data
- Upload and download control API per network type
Client-side optimization features
- UDP-based delivery, better resource utilization than for HTTP/TCP
- 100% transparent for end-users: nothing to install
- In-segment multisourcing: pre-fetching each segment from several peers at the same time
- Adaptive Device Resource Usage: our module constantly monitors core health metrics on the device (CPU, memory, QoS, battery, etc.) to adapt the efficiency algorithms to the capabilities of the device in real time
- Advanced congestion control algorithms
- Protection against uplink saturation
- Pre-buffering from other peers
- Dynamic buffer level configuration (patented)
Matching features
- Smart matching via machine learning by network topology, ISP, region, city, etc.
- Can restrict matching between specific ISPs or inside specific ISPs
SLA
- 99.99% uptime
- Instant and seamless fallback to CDN in case of any issues
- Multi-region backend for better resilience and high availability
- Can overcome short CDN downtimes by offloading delivery to the peer network
