Evolution of a „„IP
IP World
“
World“
Migration from circuit switched applications to
wireless internet
—Terminals need IP addresses
—Multimedia applications
Convergence of wireless and wireline services
—Common infrastructure/services
Higher bandwidths available
—Greater need for differing QoS
—Possible to tolerate more signalling
Switch from call-oriented to always connected
model
Desire for push services

Different Mobile Technologies
Pico Level - Bluetooth, IR
Link Level - Access Network like Cellular
(GSM, EDGE, WCDMA) , 802.11(b)
Network Level - MobileIP, GTP
Application Level - SIP, H.323 Mobility,
Dynamic DNS
Common denominator is IP
— Then security, mobility and QoS should
also be solved at the network layer by IPv6

ON GOING WORK
Multimedia will stress LAN design, but
issues are identifiable and fixable
Much work remains, progress will be
steady towards integrated audio, video,
data over LAN and WAN with network
transparency
ISDN (H.320) and IP (H.323) will coexist for
several years
Implement prudently, remember QoS
