  1. Total Standards Picture • Client PC and Server Must be Compatible at All Six Layers Application Application Transport Transport Internet Internet LAN Subnet (NIC) LAN Subnet (NIC)

  2. Upper Layers • Application Layer • Standard depends on the application • File service • Print services • Electronic mail • Etc. Application (service)

  3. Upper Layers • Transport and Internet Layers • All new servers use TCP/IP standards • Transport layer: TCP • Internet layer: IP Transport (TCP) Internet (IP)

  4. Upper Layers • Novell NetWare • Now uses TCP/IP • Before, used NetWare’s proprietary IPX/SPX • Many old NetWare servers still use IPX/SPX Application Other NCP Transport SPX Internet IPX IPX

  5. Upper Layers • Novell NetWare • IPX at the internet layer • NCP at transport & application • File service, print service, etc. • SPX sometimes at transport Application Other NCP Transport SPX Internet IPX IPX

  6. Upper Layers • All Servers on a LAN Use the Same Subnet Layer Standards, which are implemented by NICs • Servers can differ in upper-layer standards App App App TCP SPX NetBEUI IP IPX 802.2 802.2 802.2 802.3 MAC 802.3 MAC 802.3 MAC 100Base-TX 100Base-TX 100Base-TX

  7. Upper Layers • Client Software is Flexible • Speaks TCP/IP to Windows NT Server, UNIX, new Novell NetWare Servers • Speaks IPX/SPX to older NetWare Servers • Simultaneously! TCP/IP IPX/SPX
