20. Whats Next? Conferencing Limits Access local and wide area Equipment/security Bandwidth Audio requires 5-64 kbits/sec, video requires 150 - 500 kbits/sec Latency Infrastructure

21. Whats Next? Web Fast growing use anywhere no install (saves a lot of money) Lack of standards opportunity for bridging between web and traditional clients like NetMeeting Conference Servers In-house or via ISP (hosted) Security, management Bridging communications – IP and PSTN Services – web proxy, recording Development of infrastructure More bandwidth QoS in VPNs predictable bandwidth predictable latency charging
