High speed lan

Details about High speed LAN

1. HIGH SPEED LAN PRESENTED BY M.RAMYA M.SC[CS&IT]

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.

8. 10Gbps Ethernet Configurations

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)

10. FRAME TRANSMISSION ON THE LINE LAN

11. ETHERNET ALN NETWORK CABLE

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
