Video conferencing
Video distribution
Audio conferencing
Telephones
Fax
Network Computing
 Integration across one common carrier
The Network
 So that any one user has access to all services
required
 When needed
 Without disruption
Network Computing
 The network is the heart of the IT system
 Everything else is peripheral
 So the network must
Be reliable
Be secure
Perform
Be flexible
Have a future strategy

How to move forward
Shared Medium LANs
– Shared bandwidth
– All adapters same speed
– Poor for isochronous
traffic
Switched Ethernet & TR LANs
– Higher segmentation
– Dedicated bandwidth for
servers etc..
– Full duplex
 20 Mbps Ethernet
 32 Mbps Token-Ring
– Perceived speed
– Uplink connection
– Poor for isochronous
Switched Advantages
– Reduced contention
– Very easy to install
 plug and play
– An inexpensive solution
EtherSwitch LANSwitch
How to move forward
Switched LAN backbone
– Ethernet or Token Ring
– 100Base Tx or 100VG AnyLAN
– FDDI
– Etherpipes and Tokenpipes
 load balancing
– 100Base Tx, 100VG AnyLAN & FDDI
 extra speed
– But all are still shared media
