  1. Lesson 10. Examining the Protocol Suites

  2. Objectives At the end of this presentation, you will be able to:

  3. Differentiate between TCP/IP, IPX/SPX, NetBEUI, and AppleTalk. Describe the addressing schemes used by IPX/SPX and AppleTalk. Explain how IPX/SPX and AppleTalk relate to the OSI model.

  4. Network+ Domains covered: 2.1 2.2 2.4 3.2

  5. Protocol Suites Most Important for Network+ TCP/IP – Pioneered by UNIX and required for the Internet IPX/SPX – Pioneered by Novell in its NetWare NOSs NetBEUI – Used primarily in Microsoft products AppleTalk – Used primarily in Macintosh products

  6. The Router is a device that: Connects multiple networks together. Determines the optimal path to direct packets from one network to another. Router

  7. Network A Router 1 Router 2 Router 3 Router 4 Network D

  8. Router Tasks Determine the optimal path from one network to another. Switch the packet to the selected path. This is called routing. A protocol is routable if its packets can be routed from one network to another via a router.

  9. Routable and Non-routable Protocols TCP/IP – Routable IPX/SPX – Routable AppleTalk – Routable NetBEUI – Non-routable

  10. IPX/SPX Suite of Protocols used by Novell’s NetWare. Native protocol for early versions of NetWare. Starting with NetWare 5.0 you can choose between IPX/SPX and TCP/IP. Both are natively supported. Skinny and fast protocol suite compared to TCP/IP. Routable protocol

  11. NetWare 5.0 and Higher OSI Model Application Presentation Session TCP SPX Transport IP IPX Network 802.3 802.5 FDDI ARC- net PPP Data Link Physical

  12. Earlier NetWare Versions OSI Model Application Presentation Session SPX Transport IPX Network 802.3 802.5 FDDI ARC- net PPP Data Link Physical

  13. NetWare 5.0 and Higher OSI Model Application Presentation Session TCP SPX Transport IP IPX Network 802.3 802.5 FDDI ARC- net PPP Data Link Physical

  14. Ethernet Token Ring 802.3 802.5 FDDI ARC- net PPP Data Link Physical

  15. NetWare 5.0 and Higher OSI Model TCP SPX 4. Transport IP IPX 3. Network

  16. OSI Model NetWare 5.0 and Higher TCP SPX 4. Transport IP IPX 3. Network Required for Connecting to the Internet

  17. OSI Model NetWare 5.0 and Higher TCP SPX 4. Transport IP IPX 3. Network

  18. OSI Model NetWare 5.0 and Higher IPX 3. Network Handles Address Resolution and Routing.

  19. The IPX Address Format Node Address Network Address 48-bits 32-bits

  20. This unique, identifying address is called the MAC Address. MAC = Media Access Control.

  21. MAC Address A 48-bit address that uniquely identifies a node on a network. A node is defined as any device that has a MAC address.

  22. The MAC Address converted to Hexadecimal 000000000110011100000111110000011010101010011111 0000 0000 0110 0111 0000 0111 1100 0001 1010 1010 1001 1111 0 0 6 7 0 7 B 1 A A 9 F

  23. With IPX, the node address is usually the MAC address. Network Address Node Address = MAC Address 2F-3E-4D-5C 00-67-07-B1-AA-9F 48-bits 32-bits

  24. IPX is to the IPX/SPX protocol as IP is to the TCP/IP protocol. Both IPX and IP are in the Network Layer. Both handle Address Resolution and Routing.

  25. OSI Model TCP SPX 4. Transport Ensures that messages are delivered error-free and in the proper sequence.

  26. Microsoft Windows OSI Model TCP SPX 4. Transport Provide Connection-oriented Transport.

  27. Two types of message delivery services: Connectionless – Comparable to normal mail delivery. Connection-oriented – Comparable to Registered Mail, Return Receipt

  28. Connection-oriented Transmission: Through a series of hand-shakes, a specific delivery path is agreed upon. Each packet is acknowledged as it is received. Every packet follows the same route. A very reliable form of delivery. A relatively slow form of delivery.

  29. Connectionless Transmission: Packets are sent via any available path. Packets are numbered because they may become lost or duplicated, or they may be received out of order. Faster than connection-oriented transmissions. Less reliable than connection-oriented transmissions.

  30. NetWare OSI Model SPX 4. Transport The connection-oriented transport protocol for the IPX/SPX suite.

  31. SPX is to the IPX/SPX protocol as TCP is to the TCP/IP protocol. Both SPX and TCP are in the Network Layer. Both are Connection-oriented Transport Protocols.

  33. AppleTalk

  34. AppleTalk Developed by Apple Computer for its Macintosh line of computers. AppleTalk Hierarchy: Sockets, Nodes, Networks, Zones. Routable Through the use of the proper Client, it can connect to Netware, Unix, and Windows NT/2000-based networks.

  35. AppleTalk OSI Model Application Presentation Session AppleTalk Transaction Protocol (ATP) Transport Datagram Delivery Protocol (DDP) AppleTalk ARP (AARP) Network 802.3 802.5 FDDI LocalTalk Data Link Physical

  36. AppleTalk OSI Model Application Presentation Session Transport Network 802.3 802.5 FDDI LocalTalk Data Link Physical

  37. AppleTalk OSI Model Application Presentation Session Transport Datagram Delivery Protocol (DDP) AppleTalk ARP (AARP) Network Data Link Physical

  38. AppleTalk Network Addressing Scheme Network Address Node Address Socket Address 16-Bits 8-Bits 8-Bits

  39. AppleTalk uses Dynamic Addressing. As opposed to the static arrangement used by IPX/SPX. AppleTalk automatically assigns each node a network address each time the node connects to the network.

  40. AppleTalk allows the Network Administrator to divide the network into Zones. Zones are defined when the Network Administrator configures the AppleTalk Network. Zones are logical groups of nodes or networks. Examples: Finance Zone, Sales Zone, Engineering Zone, etc.

  43. Cross Platform Connections

  44. Connecting a Macintosh to a Netware Server Install Netware Client for MAC OS on each Macintosh workstation. Uses IPX to communicate on the network. Enables Macintosh user to access NetWare Servers. Allows users to access all resources to which they have rights. Does not allow Macintoshes and PCs to share AppleTalk Printers. Install NetWare Services for AppleShare on one NetWare Server.

  45. Connecting a Macintosh to a Windows NT/2000 Server File Services for Macintosh Print Services for Macintosh Collectively called File and Print Services for Macintosh. They allow Windows clients and servers to share files and printers with Macintosh workstations.

  46. File and Print Services for Macintosh Configures Windows NT/2000 servers with the AppleTalk protocol. Installed in Windows 2000 Server from the Control Panel using Add/Remove Programs.

  47. Cross Platform Network Printing The page description language is often a barrier to cross platform printing. Macintosh and many Windows printers use a page description language called PostScript. Macintosh and Windows machines can both print to the same PostScript printer if they use the same protocol, or if they go through a Print Server.

  48. Solving Cross Platform Network Printing Problems Install a print server. Install a special program or hardware (usually on the Macintosh) that allows the platforms to coexist.

  49. Connecting a Windows NT/2000 to UNIX/Linux Samba allows a Windows NT server or client to access a Unix server as if it were another Windows NT machine. A free software suite available from www.samba.org

  50. Differentiate between TCP/IP, IPX/SPX, NetBEUI, and AppleTalk. Describe the addressing schemes used by IPX/SPX and AppleTalk. Explain how IPX/SPX and AppleTalk relate to the OSI model.
