Network protocol

  1. 1. Network Protocol(IP, IPX, and NetBEUI) Drew Belisle 2nd Hour PC Networking 11/20/09
  2. 2. Definitions• Network Protocols are rules that control the communications between computers on the internet.• Internet Protocol (IP) is the method for data to get from one computer to another over the internet.• IPX is Internetwork Packet Exchange.• NetBIOS Extended User Interface (NetBEUI) is a program that allows computers to interact within a local area network.
  3. 3. How IP Works• IP accepts data from a higher-level protocol and it formats the package that has the addressing information.• It sends the packet, to where it is suppose to go, by underlying physical network architecture.• The info. in the IP datagram header is used for a hop-by-hop basis to get it to the right destination.• IP doesn’t check to see if the packets got to the right address and the packets may arrive out of order, which means IP may be unreliable sometimes.
  4. 4. IP Packet
  5. 5. How IPX Works• IPX operates at the OSI Network layer. IPX addresses and routes the packets from an area to another area on an IPX internetwork.• It uses the address fields to make routing decisions in its header and from other information that it receives.• It uses this info. to forward the packets to the correct destination node or to a router that provides the path to the correct node.
  6. 6. IPX Packet • Checksum-Indicates that it isn’t used when the bit field is set to 1’s. Structure • Packet length-Specifies the length. • Transport Control-Indicates the number of routers the packet has passed through. • Packet Type-Decides what upper- layer protocol should receive it. • Destination Network, Node, and Socket-These specify the destination’s information. • Source Network, Node, and Socket- These specify the sources information.
  7. 7. IP and IPX• These computers are using IP and IPX for the internet.
  8. 8. How NetBEUI Works• NetBIOS provides communication interface between a application program and an attached medium.• It provides services described in the OSI, but it doesn’t handle all of the frame formatting.• NetBEUI handles all of the frame formatting that is not handled by NetBIOS.• It provides transport and network support to NetBIOS.
  9. 9. History of IP• 1974-IP is invented by Vinton G. Cerf and Robert E. Kahn.• Late 1980’s-IP is largely adopted.• Early 1990’s-They determine that they are going to run out of numbers for the numbering system.• 1995-IPv6 is released to prevent running out of numbers. It provides trillions of more addresses than IPv4.• 2004-RCN used Voice over Internet Protocol technology for phone service.• Today-The internet uses IP still and will for many years.
  10. 10. History of IPX• 1983-LAN is based on IPX by Novell.• 1992-Development of IPX stack for Mac computers.• 1997-IPX became the most common protocol and many legacy networking applications will work on it.• 2002-Microsoft notices that companies were eliminating IPX from their operating systems.• 2004-Novell was having performance problems with IPX.• 2006-IPX has been pretty much replaced in newer products.
  11. 11. History of NetBEUI• 1985-IBM and Microsoft introduce NetBEUI.• 1991-NetBEUI is a newer version of NetBIOS.• 1996-You could install a dial-up adapter using NetBEUI protocol.• 2001-WindowsXP was introduced without NetBEUI.• 2002-Many people set aside NetBEUI as worthless and Microsoft decides that they are not going to use it anymore.
  12. 12. Types and Manufacturers of IP• The 2 main types of IP are IPv4 and IPv6. – IPv6 was created because IPv4 was running out of numbers.• There are no real manufacturers of IP because it comes with the internet when you get it.
  13. 13. Types and Manufacturers of IPX• There are no types of IPX.• There are no real manufacturers of IPX, but it used with Novell.• There are no manufacturers because it comes with certain types of programs.
  14. 14. Types and Manufacturers of NetBEUI• There are no real types of NetBEUI• There are no real manufacturers of NetBEUI, but it was created by IBM and Microsoft.• It comes with certain programs is the reason why NetBEUI really doesn’t have any manufacturers.
  15. 15. Purchase Prices• IP-It is comes with the internet, but the programs that has it on them, cost money.• IPX-It comes with certain programs, so it is free, but you have to buy the program with it on it.• NetBEUI-It is on certain programs so you don’t have to pay for it but you have to buy the program.
  16. 16. Purchase Prices• Programs that have IP-Windows NT, Windows 2000, Windows XP, Windows 95/98/Me, Windows 7, and Macintosh: Cost=$25-$160• Programs that have IPX-Windows NT, Windows 2000, Windows XP, and Windows 95/98/Me: Cost=About the same as programs that have IP.• Programs that have NetBEUI: Today programs don’t have NetBEUI so it doesn’t cost much. Windows 2000 is the program with it on it and it costs $38-$165.
