Today's Topic

• I'm an ISP engineer from IMnet.• IMnet will make a field trial of Live

Streaming of APAN Meetings, Fukuoka.

• I'll explain about this field trial and make an announcement regarding it.

What is IMnet?

– IMnet is an academic Internet Service Provider (ISP) built for exchanging research traffic among research organizations and networks

– running since 1994– Funded by Japan Science and Technology

Corporation (JST)– Various research organizations and networks

are connected as our customers and partners – APAN is one of our partners (IMnet is given

some transit by APAN)– offering IPv6 connectivity, which is directly

given by 6TAP via Transpac PVC.

About this Field Trial (1)

– During APAN Meetings, we will make a field test of video streaming in order to evaluate robustness and video quality of today's streaming system through the IPv6 Internet.

– IPSec will be applied between the global IPv6 edges for secure data transport.

– Streaming Server and Client themselves use IPv4 for its video distribution, however, IPv4 over IPv6 tunnel is applied between Server and Client

About this Field Trial(2)– Following streaming servers are employed in this trial

• Helix Producer, Helix Universal Server (RealNetworks)

– There are several main components in this streaming system• Video camera, Encoder, Transmitter, Splitter, Client• Encoder will encode the video data from Video camera

and send it to Transmitter. Those are all set here (Fukuoka).

• Transmitter will relay encoded data to Splitter, which is set in the IMnet backbone (Tokyo).

• Splitter have an ability to distribute live data to many Clients.

– Client can use RealPlayer8 or RealOnePlayer to watch the live streaming.
