34. DIFFERENCES

35. DIFFERENCES (CONT.)
• Improve real-time
– Low latency
• Decrease cost
– Low server usage
• Secure communication
– DLTS mandatary
– A Study of WebRTC Security

36. MINIMUM SYSTEM REQUIREMENTS
• For P2P establishing
– Signaling server
• For NAT traversal
– STUN server
– TURN server

37. [AD.] SKYWAY

44. CURRENT TRAFFIC MODEL
North to South

45. WITH WEBRTC
North to South
East and West

46. TWO LAYER MODEL WILL BE APPLIED
North to South : Non real-time data
• Archive contents
• Management data
East and West : Ralt-time data
• Audio / Video stream
• Control stream

47. HOW TO HANDLE EAST AND WEST?
• Requirements
– High BW, Low latency and packet
loss
• Methods
– QoS control
– Elastic Traffic Management
NFV
+ SD-WANwill meet

48. HOW TO HANDLE EAST AND WEST?
(CONT.)
will meet
IaaS / Fog Computing
+ NFV
+ SD-WAN

49. FROM NW OPERATOR PERSPECTIVE
• Handle next flow for East and West
– Two layer model
• Everything is on Software
– SaaS, Paas, IaaS, NFV, SD-WAN
• Elastic operation with high scalability

50. SUMMARY
• What’s WebRTC?
– Just a feature, now in early majority stage.
• What business innovation does it lead?
– Embedding real-time streaming feature on top of bunch of services.
• What technology does it involve?
– Protocol framework with existing technology under on going
Standardization .
– Expectation : all major platform will support in the near future.
• What is the impact for us, network operator?
– Brings us East and West flow
– Elastic traffic management with all virtual systems
