33. TECHNOLOGYW H A T T E C H N O L O G Y D O E S I T I N V O L V E ?

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

38. ADVANTAGE?
• Technical features
– no What’s new.
• Advangate
– Everything is standardized !!
• Decrease the cost of development
• Increase interoperability
• Easy to deploy in multi-device environment

39. IT WORKS ON

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
