VC Infrastructure

• In the beginning, we had this:

• That’s right; nothing!

Videoconferencing Growth

• Cairns and Townsville were two islands connected via ATM link

• ISDN BRIs kept in place for redundancy after migrating to IP• No firewall traversal, ports had to be opened as required• Overall an expensive and labour intensive solution• Does not scale very well – if at all...

.The present

Videoconferencing Endpoints

Benefits of current infrastructure

• Call Access and Control (CAC) including bandwidth management, interworking between IPv4 and IPv6 and interworking of SIP and H.323

• Scalability – addressing using E.164 Alias and SIP URI• Quick and easy way of neighbouring with other organisations such as Qld Health• Provisioning of JabberVideo (Movi) clients• Secure firewall traversal

Transwhatnow???

Transcoding and transrating; we all do it Serving all comers: H.323SIPH.320, HDSD

JCU Singapore

• 7 end-points + desktop videoconferencing• Initially experiencing critical packet loss• Old firewall found to be part of the problem• Moved all VC traffic to separate VLAN bypassing old firewall,

and using a temp Linux firewall instead.• JCUS end-points routed externally and registers with VCS-E.• Awaiting LAN upgrade and new firewall replacement.
