Future Interactive Video• Compressed Video Switched Service

• Generation II MCU’s and Coders – Decoders• Excellent investment• Excellent quality

• Migrating to Generation III (H323/320/321)• Limitations (Speed – Switching – Cost)

• Smattering of H323 Point to Point Testing• Lucent• Cisco• Intel• VTEL – PICTEL – ACCORD – Video Server

Future Interactive Video Switching

• Marriage of the old and new

• H323/320/321 switches in the main hubs

• Dial Switched – H323 – H320 – Video Streaming

• Migrate older switches to the peripheral edge

• Maintain quality of services and integrate newer technologies

Future Internet – January 2000• More Plans and Talking • New Internet Services

• QWEST - UMCP• QWEST – UMB

• Scalable 10Mb/s to 155Mb/s• Redundant (Physical)

• Internet 2• Mid Atlantic Crossroads• net.work.Maryland

• Bandwidth or Fiber ?

Summary• Demand

• Internet use is on the rise -beyond exponential• Video use is going up – demand for H.323 and H321 ATM!… it’s stable and profitable …• Costs for ISP services rising –well sort of…• Committed institutional services can not be met• Virtual classrooms on the rise –they’re everywhere

• Future Infrastructure• Need to shift from multiple T-1’s to DS3’s at the edge • Need more funding –serious funding• net.work.Maryland –reduce interlata costs, perhaps?• Must prepare USM for access to emerging networks and technologies

• Internet 2 – MAX - NGI
