IP VOICE (VoIP)

Toll bypass approach:• Keep existing telephones and PBXs• Use VoIP to provide connectivity between the PBXs

VoIP based on G.729 codec:• 8kbit/s CS-ACELP codex• Excellent voice quality • MOS 3.92 (compare to MOS 4.1 for G.711/pcm)

16

Page 18: Internet2 – Spring Meeting “INTERNET TWO – Is It The Future of GDLN?“ Dr. Vili Brajovic Global Communications Manager

VOICE HEADER COMPRESSION

• VoIP is based on 8Kbps algorithm, which with overhead requires

26.4Kbps IP channel (40 bytes IP/UDP/RTP header)

• When RTP header compression (RFC2508) is used, for the same algorithm only 11.2Kbps IP channel is needed

(40 bytes of IP/UDP/RTP reduced to 2–4 bytes)

17

Page 19: Internet2 – Spring Meeting “INTERNET TWO – Is It The Future of GDLN?“ Dr. Vili Brajovic Global Communications Manager

IP VIDEO

• Room based videoconferencing systems

• H.323 based videoconferencing

• 256Kbit/s per call

• G.711 for audio (64Kbits/s)

• H.261 for video (~180 Kbit/s)

18

Page 20: Internet2 – Spring Meeting “INTERNET TWO – Is It The Future of GDLN?“ Dr. Vili Brajovic Global Communications Manager

ASYMETRICAL SCPC SATELLITE CHANNELS

• 10 SCPC 768Kbps satellite channels combined into A single sub-group

• Each sub-group is served by a single 8Mbps outgoing channel and eight 768Kbps return channels

• Asymmetrical solution provides an excellent bandwidth utilization

• One single 256Kbps outgoing video stream is used to feed all eight nodes during multi-point video session

19

Page 21: Internet2 – Spring Meeting “INTERNET TWO – Is It The Future of GDLN?“ Dr. Vili Brajovic Global Communications Manager

IP MIGRATION BENEFITS

• Single communications pipe for voice,data and video

• Low operation and management costs

• Low communications equipment complexity (only router)

• Easy integration with local area networks (desk-top video)

• Improved quality of all services

20

Page 22: Internet2 – Spring Meeting “INTERNET TWO – Is It The Future of GDLN?“ Dr. Vili Brajovic Global Communications Manager

IP MIGRATION BENEFITS(continued)

• Simple re-engineering for future growth

• Automated videoconference scheduling

• Automated dynamic service interchange

• Full compatibility with Internet
