Why WebRTC for remote camera?
 Web Cam
• need IP reachability, low quality video, no voice,
one-way communication
 Live Streaming
• latency (sec order), one-way communication
 Proprietary system
• low interoperability, expensive, license issues
Before WebRTC …

Why WebRTC for remote camera?( cont. )
 no need of IP reachability (under NAT is ok)
 low latency ... (msec order)
 Interoperable
 Be able to use 3rd party PaaS
with WebRTC …

WebRTC
in edge computing
scenarios.

Typical use cases for Edge Computing
Alert
• Local monitoring
• Intrusion detection
• Noise detection
• …

What makes Edge Computing easy?
• Location independent setting
• Center control authentication
• Minimize security policy setting (e.g. FireWall)

Remote monitoring, Big data Analysis
• No global IP address setting
• No firewall setting
• Same monitoring architecture

Location free. Portability
Signaling
server
No reconfiguration is needed for
reachability
Every single connection is dynamically
established on the fly.

Also applied to generic devices
Signaling
server
Zero touch provisioning
for all single IoT
devices.
No need of relay server
for real time sensor
monitoring.

Three benefits of WebRTC for Edge
computing use cases
• Ease of management
• Security
• Fault tolerance

Point 1 : Ease of management
Signaling
server
• Dynamic establishment of
reachability
• No configuring firewall
• Every connection is
managed by Signaling
server

Point 2 : Security
• No open tcp/udp inbound port is needed.
• All single data is encrypted
• Every connection is managed by signaling server

Point 3 : Fault tolerance
When local analytics system has trouble …
-> Establish new RTC connection and switch to another edge system.

Easy ad-hoc provisioning
WebRTC brings us flexible, secure and fault tolerant Edge computing system
Easy to build in an Ad-hoc way

Special announcement: SkyWay IoT SDK
• Global accessible “Janus Gateway”
even under NAT environment.
• Real time camera monitoring
• P2P full mesh pub/sub API
• P2P REST API

Headless WebRTC SDK for linux box

Summary
• WebRTC for IoT
• Several existing use cases
• Easy to setup, low latency, interoperability
• Be able to build system within eco-system.
• Edge Computing
• Ease of management
• Improve IoT security
• Fault tolerance
