  1. 1. IBM Network Products Strategy
  2. 2. IBM Strategy  Network Computing –Definition –Migration plans –Future direction –Product set.
  3. 3. The Networking Environment The Network Applications Collaborative Working Multimedia Client/Server
  4. 4. Network Computing  The integration of all IT services Mainframes Servers Desktop PCs Laptop PCs Video conferencing Video distribution Audio conferencing Telephones Fax
  5. 5. Network Computing  Integration across one common carrier The Network  So that any one user has access to all services required  When needed  Without disruption
  6. 6. 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

  9. 9. 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
  10. 10. 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 EtherStreamer Switch LANStreamer Switch 8274 & 8260 Intelligent Hubs
