1. ABCs of Network Design ICCM 1998 Bill Jack

2. What this session will NOT cover Detailed Discussion about Netware Anything about Unix / Linux Windows95/98/NT internals Details about the fine art of TCP/IP Lantastic, Arcnet, Baseband, Pathway, etc…..

3. What this session will cover How to layout an efficient network Ethernet and network Protocols Hubs / Switches / Routers Wiring configurations Principles of adding Internet to your local network Acknowledge Token-ring exists

4. Elements of an Effective Network Media - wiring Hardware Configuration Topology Operating System Protocol

5. Media Thickwire (AUI cable) Thin Coax (10Base-2) –Bus - 30 node limit - 185m max Twisted Pair (100Base-T / 10Base-T) –Cat5 cable - Star - 100m max Fiber Optic ( 100Base-FL / 10Base-FL)

6. Topology Ethernet (10 mbps) –EtherTalk (Apple) Fast Ethernet (100 mbps) Token-Ring Future –GigaEthernet (1000 mbps) –DSL, Fiber Channel, ISO Ethernet

7. Network Equipment Network Interface Card (NIC) Hubs & Repeaters –Unmanaged hubs –Managed hubs –Limit of four hubs between any two nodes –General broadcast to all nodes

8. Network Equipment Switches –Filters and forwards Ethernet packets based on their source and destination addresses. –Provides bandwidth matching between 100Base-T and 10Base-T equipment Switching Hubs –Bandwidth matching, no filtering

9. Network Equipment Transceivers –Devices to interface different types of media into a hub or switch Routers –Similar to a switch in that they filter and forward packets to another network segment. –Protocol specific

10. A Simple Two Node Network 2 Network Interface Cards Ethernet 10Base-T or Coax Windows NetBEUI

11. Multi-node 10Base-T Net

12. Multi-node Coax Network

13. Multi-Node / Multi-Hub Net

14. Switched Backbone

15. Operating Systems Windows for Workgroups Windows 95 Windows 98 Windows NT Novell Netware

16. Protocols AppleTalk - Localtalk IPX - Netware NetBEUI - MicroSoft TCP/IP

17. Network Protocols

18. NetBEUI Simple –No Brainer Setup –NO maintenance Broadcast mode Practical limit of 25-30 nodes Not Routable Do not confuse with NETBIOS

19. IPX Simple –No brainer setup –No maintenance Broadcast mode with cache Routable but … Novell based - HP JetDirect support

20. TCP/IP Scalable protocol of choice Integrates with Internet Direct Addressing Routable Skills needed for design, installation and maintenance
