2. Agenda
Conferencing applications in NDN
Conferencing control and management
A proposal to a control system for
conferencing applications
Summary

3. Conferencing Applications in NDN
Conferencing applications
Media + Control
Media: data exchange among participants
Control: registration, floor control, etc.
Advantages in NDN
No traffic concentration point
Efficient distribution through caching inside network
Examples
ACT
Server-less approach
XMPP-based whiteboard and audio
Hybrid approach: server-less media plane + server-
based control plane
HUAWEI TECHNOLOGIES Co., Ltd. Page 3

4. Conference Control and Management
Control and management functions
conference agenda, updates, feedback
conference registration
conference floor control
etc.
HUAWEI TECHNOLOGIES Co., Ltd. Page 4

5. Server-based Conference Control and
Management
Server functions
Repository (agenda, updates, registration form,
feedback form, etc.)
Speaker list
Q&A list
Aggregation (form return, Q&A request, etc.)
HUAWEI TECHNOLOGIES Co., Ltd. Page 5

6. Challenges
Server-based conference control and
management:
Single point of failure
Server load overflow
Server cluster
Maintenance of cluster membership
Maintenance of server-participant binding

Server cluster
An organizer initiates the server cluster.
Participants sign on with one of the server in
the server cluster.
Server cluster expands/shrinks with the
footprint of the participants.
No cluster membership
No fix binding between server and participants
