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 …

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

18. Copyright © NTT Communications Corporation. All rights reserved. 18
Remote monitoring, Big data Analysis
• No global IP address setting
• No firewall setting
• Same monitoring architecture

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

22. Copyright © NTT Communications Corporation. All rights reserved. 22
Point 1 : Ease of management
Signaling
server
• Dynamic establishment of
reachability
• No configuring firewall
• Every connection is
managed by Signaling
server

23. Copyright © NTT Communications Corporation. All rights reserved. 23
Point 2 : Security
• No open tcp/udp inbound port is needed.
• All single data is encrypted
• Every connection is managed by signaling server

24. Copyright © NTT Communications Corporation. All rights reserved. 24
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
