Video over IP Tony Johnston Cable & Wireless Optus Principal Consultant Data & Business Services

Agenda Evolution of Video over IP IP Data Transport Options Network QoS Requirements Video over IP services trialed by Optus Future Developments

Evolution of Video over IP Early Adoption Mainstream Adoption Mature Market We are Here! Normal Technical Adoption Curve Time % Market Share

IP Data Transport Options –Core Technology - ( covered by Allan ) –Access (Tail) technology ISDN xDSL Frame RelayATM Gig Ethernet etc… –Lots of Options now available

Network QoS Requirements –Packet loss –Network Delay –Priority for Real Time data. Same issues as Voice over IP Unlimited bandwidth is not the only Solution

Video over IP Tests Aim –As a carrier to understand the limitations and issues over core networks and platforms. –to compare Internet based services performance to ISDN based services.

Video IP Equipment used GVT supplied PictureTel 900 Videoconference system PictureTel 600 Videoconference system. PictureTel 330 Multiconference Unit (H.323) InnoMedia IP VideoPhone (2)

Carrier Services utilised –Internet Services (Optus ADSL). 2 Melbourne locations 2 Sydney locations –IP Datacentre with High speed connection to Internet. (Fibre) –Residential Internet services –Optus Cable modem –Telstra ADSL.

C&W Optus Internet GVT, MelbourneGVT, Sydney Cisco Systems AGS + Video-conference Bridge 5Mb PVC(Internet) NetAccess ADSL 2 Mb/256K Optus MDC Melbourne NetAccess ADSL 2 Mb/256K NetAccess ADSL 1 Mb/256K NetAccess ADSL 1 Mb/256K ADSL Modem ADSL Modem ADSL Modem ADSL Modem Optus, Sydney Optus, Melbourne Cable Modem Bigpond ADSL ADSL Modem

Point to Point Tests Optus ADSL connected V/C units gave best performance at 128K throughput settings. »Capable at 256K but higher loss ratio »Included Netmeeting & IP Videophones Residential Internet services –Optus Cable modem »PictureTel K quality –Telstra ADSL. »NetMeeting - 64K Quality

Multipoint Tests Videoconference Bridge connected and worked with all V/C units. –PictureTel 900 & 600 Videoconference systems, Optus ADSL and Cable modem –IP Video phone over Optus ADSL –Netmeeting over Otpus ADSL –Note: Telstra ADSL NetMeeting connection not tested in Mulituser session. Best performance at 128K throughput settings.

Future Developments All new Videoconference products are supporting functional IP based services. Carriers to consider implementing a Public Video IP network and ISDN Gateway links.

Summary Latest versions of Videoconference devices are reliable and functional for IP. Dedicated IP-VPN networks provide required QOS for a Video over IP Service Internet services work, but are not yet of reliable QOS for commercial usage. Future Plans for carriers may include a Video over IP Public IP-VPN and Gateway services.
