CCNxCon2012: Session 2: A Distributed Server-based Conference Control and Management for NDN Conferencing Applications

1. A Control System for Conferencing Applications in Named-Data Networks Jun Wei Huawei US Innovation Center www.huawei.com FUTUREWEI TECHNOLOGIES, INC

2. Agenda Conferencing applications in NDN Conferencing control and management A proposal to a control system for conferencing applications Summary HUAWEI TECHNOLOGIES Co., Ltd. Page 2

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 HUAWEI TECHNOLOGIES Co., Ltd. Page 6

7. A Control System for Conferencing Applications in NDN 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 HUAWEI TECHNOLOGIES Co., Ltd. Page 7

25. Discussion Server-based conference control and management: Repository (agenda, updates, registration form, feedback form, etc.) Speaker list Q&A list Aggregation (form return, Q&A request, etc.) Server cluster serve one or both of server functions HUAWEI TECHNOLOGIES Co., Ltd. Page 25

26. Discussion HUAWEI TECHNOLOGIES Co., Ltd.

27. Summary Dynamic and distributed control server cluster management: scalable and robust No specific membership maintenance No specific binding between server and participating clients Dynamic and scalable Cluster changes on demand Efficient and robust Participates always interact with the nearest server HUAWEI TECHNOLOGIES Co., Ltd.
