• They choose to join of the conference, this results in discovering all the active participants.

– As a result the UE reachability is programmed in the CCN FIBs for the new participants
Audio/Video flows
• The participant then enables his own Audio/Video stream, which any remote participants will be
able to request and receive. In the demo, we show two consumers requesting a mobile producer’s
content.
– We will demonstrate an all party conferencing scenario.
• A participant can join and leave the conference at will.
• Mobility-as-a-service will be demonstrated by, first having the conferencing application in the UE
explicitly requiring mobility support, which triggers appropriate control and data plane state in
created in the network. Then mobility is demonstrated by moving participants between subnets
without interruption during their video conferencing without affecting the user experience.
• The demo will be over Wifi, considering the fact that any other licensed transport can also be
accommodated with appropriate L3/L2 adaptation.
• We show seamless handover of the mobile A/V producer node by switching its Wifi interface from
one AP to another. The consumer side performance during this handover is shown in Figure 19. We
note for the demo system, the consumer’s session disruption is around 100ms equivalent of video
frame loss, ensuring seamless experience.
