FogVDN - The Video CDN in the Fog with Crowdsourcing

FogVDN proposed by Pear, future oriented, focuse on online video streaming service. It is an important component of the Pear Fog. It has the following features

Integrate Easily, CP or CDN can "Click to Start"

<video id="v1" src="https://example.com/v1.mp4"></video>
<script src="PearPlayer.js"></script>
<script>
    var player = new PearPlayer('#v1', token, opts);
</script>

Web friendly, uses the Web open standard (No plug in, just need HTML5 and WebRTC)

Integrate with your project easily , only need few JS code.

Crowdsourcing, Massive Node, Wide Coverage

  • Massive, stable service node.
  • Most bandwidth, storage and computing resources were collected by crowdsourcing from the stabilize online edge devices owned by users.
  • Service cover all regions, all operators, all edge of the network.
  • Dynamic, real-time monitoring and scheduling, data transmission distances would be "zero hop".

节点架构

Low Latency

Through massive node and dynamic, real-time monitoring and scheduling, data transmission distances would be "zero hop".

Multi Source, Robustness

  1. In data transmission, the traditional CDN is one-to-many relationship, that means, the average of the user quality of service is inversely proportional to the number of users. Pear FogVDN schemes to get file data from multi channels, reducing the dependency on a single point or single link, solve the HD video play back problem that the single link may not meet the bandwidth, also solve the problem of weak network packet loss problem through the UDP channel, users will have a better watching experience.

multisources

  1. It will dynamically explore the status and service capabilities of other nodes, automatically switch to the optimal node group and adjust the data ratio to guarantee the user experience.

Support International Open Standard Protocol

Web Friendly, "Connect the World"

High Effciency, Customized Algorithm in VoD, Live, VoIP.

Safe and Reliable

It ensures the secure storage and transmission, prevents the data from being tampered, avoids the leakage of the copyright document and the content hijacking.

  • All edge nodes support TLS, HTTP use HTTPS(HTTP2.0) by default.
  • WebRTC channel tranfer data encoded by SCTP and DTLS.
  • Signaling communication by WebSocket, also encrypted by TLS/SSL.
  • Optional data encryption, segmentation, fragmentation and blocking.

Low Cost

Compared to the traditional CDN which relying on expensive servers and bandwidth. Pear FogVDN with massive nodes and sharing economy, the price is lower than traditional CDN.

Network Awareness, Content Prefetching, Personalization

  1. Accurate service

    • Get user's real IP address (although use OpenDNS or VPN), and mapping the area, ISP with a probability of 99.9%, choose the "zero hop" node for service.

  2. Efficient content distribution and distribution network

    • Accurate, real-time get the high frequency data, push the content to the edge node quickly.

  3. Big data based recommendation, prediction and prefetching

    • Provide API and other service, for the CP which have user personas and content feature,content prefetching can be accurate to one user and the "Small-world"(A social networks concept).
