2. HIGH –SPEED LAN’S
• Speed and power of personal computers has increased. LAN viable essential
computing platform.
• Client /server computing dominant architecture. Web – focused intranet.
• Frequent transfer of potentially large volumes of data in a transaction – oriented
environment.
• 10-Mbps Ether net and 16 –Mbps token ring not up to job.

3. CHARACTERISTICS OF HIGH – SPEED LAN’s

4. USES OF HIGH-SPEED LAN’S
Centralized Server Farms
Client system draw huge amount of data from multiple centralized servers.
Example- Color publishing
Servers holds tens of gigabytes of image data that must be downloaded to
workstations.
Power workgroups
Small number of users drawing data across network.
Example – Software development group, computer – aided design(CAD).
High – speed local backbone
LAN’s grow at a site.
High = speed interconnection is necessary.

5. Extension made to older LAN standards to get higher data transmission speeds:
 Fast Ether net – 100 Mbps for Bus networks.
 Gigabit Ether net – 1Gbps.
 FDDI – 100 Mbps for Token Rings.
 ATM LAN’s

6. USAGE OF LAN
A work to internet connection would most likely require broadcast network
(LAN) with a connection to the internet (packet switched network).

7. THE EMERGENCE OF HIGH – SPEED LANs
Trends
Computing power of PCs has continued to grow. MIS organizations
recognize the importance of LANs in the transfer of large volumes
of data in a transaction oriented environment.

9. TYPES OF COMMUNICATION NETWORKS
• Traditional
 Traditional local area network(LAN)
 Traditional wide area network(WAN)
• Higher – speed
 High – speed local area network(LAN)
 Metropolitan area network(MAN)
 High – speed wide area network(WAN)

12. BACKBONE NETWORK(BN)
• Backbone Network – a large high – speed central network that connects all the
terminals, microcomputers, mainframes, local area networks, and other
communications equipment on a single company or site.
• Some times called Campus Area Network(CAN). Use Higher speed circuit for
connectivity.

13. FAST LAN’s
Advances in transmission speed and distance.
Technology
FDDI
Fast Ethernet
Application
Inter – LAN backbones
100Mb/s and upper bandwidth is needed
