11. The History and Future of Token Ring The Madge Perspective

14. Communications Revolution Transaction Processing Client-Server Applications Intranets & Web-based Communications Multimedia Communications Ubiquitous Email Office Automation Network Demands 1970 1980 1990 2000

15. Network Impact of Changes Smaller shared segments Shared 10Mbps Switched 10Mbps in backbone 100Mbps in backbone Switched 10Mbps to desktop 1Gbps in backbone Switched 100Mbps Ethernet Major technology change every 2 years Users forced to upgrade every time

16. Token Ring Meeting the Challenge Smaller shared segments Shared 10Mbps Switched 10Mbps in backbone 100Mbps in backbone Switched 10Mbps to desktop 1Gbps in backbone Switched 100Mbps Token Ring Shared 4Mbps Shared 16Mbps Switched 16Mbps in backbone Token Ring has consistently been able to meet demands placed on it by new applications

20. The ROPE Fallacy For existing Token Ring installations, incremental upgrades will almost always be easier to implement and cost less than attempting a change of network technology at every desktop R ip O ut Token Ring P ut in E thernet

21. Token Ring Performance 16 + 16  100 Switch DTR is the same or faster than 100BaseT for server backups Switch TR Workstations run significantly faster into TR based servers compared with those 100BaseT based DTR DTR

31. High Speed Token Ring Explained

35. HSTR End Stations Token Ring ISO Layer PHY Physical Data Link Network MAC Interface Protocol Driver - NDIS/ODI TCP/IP, IPX/SPX, NetBEUI 16/4 100 Token Ring Network 16/4 - Manchester Encoding LLC - I & II 100 Mbps - 4b/5b (as used in Fast Ethernet & FDDI MLT-3)

43. HSTR Delivers  Fault Tolerance  Scalability  Compatibility  Simplicity  Performance  Ethernet Co-existence SR support enables multiple redundant paths, and duplicate MAC addresses Scales to 100 Mbps and 1 Gbps Uses native Token Ring frame formats and packet sizes No new protocols to learn Native TR: Good client server performance 4.5K bytes frame size: faster backups Supports 802.1Q VLAN tagging enabling Ethernet packet transport over HSTR High Speed Token Ring  Cost Leverages low cost high volume components for best value

46. HSTR networking example 4/16/100 Mbps Server NICs HSTR used for inter-switch links HSTR Power-users connected into Ringswitch HSTR up-link for workgroups 4/16/100 Mbps NICs
