Error 404--Not Found

From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:

10.4.5 404 Not Found

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.

If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

Internetworking with TCP/IP Level I

Overview:

TCP/IP has become the most important protocol structure in the networking industry. It has replaced virtually all other layer three/layer four suites. Digitized voice, video codec output, HVAC control data, and traditional transaction processing data all use it. IP addresses are now contained in a wide range of devices from computers to watches. Understanding the dozens of protocols that make up the TCP/IP suite has become a prerequisite to success in working with networks.

This, the first part of a two-part class, is a solid overview of the TCP/IP protocol environment. The first class covers packet processing, protocol headers, Ethernet, SNAP, layer two and layer three addressing, subnets and masks, IP, ARP, ICMP, BOOTP, and DHCP. Furthermore, comparisons to similar environments such as Novell’s SPX/IPX are made to clarify the study. Students use protocol analyzers and test equipment in labs that elaborate on the concepts covered in lecture. Internetworking devices including bridges, switches, routers, and gateways are also covered in some detail.

If you have some experience in working with networks, this seminar will complete your training. It will also provide excellent exposure to the high quality tools used to troubleshoot and analyze TCP/IP networks. If you are a novice at networking but have some experience with other aspects of computing, you will receive an excellent overview of how the network works at a technical level.

This seminar will enable you to:

  • Understand the overall TCP/IP protocol structure.
  • Grasp the differences between layer two switches, layer three switches, routers and bridges.
  • Understand how packets are encapsulated by analyzing the data inserted by each layer as the message is created.
  • Work effectively with Ethernet and IP addresses.
  • Demystify subnet masks and learn how the logical view of the network changes when the mask is modified (Students have reported that this is one of the best sections of the class.)
  • Understand the codes in the headers that allow the implementation of quality of service.
  • Compare the theoretical seven-layer model to the actual implementation of TCP/IP by devices in the network.
  • Analyze in some detail how a router processes a packet and how it decides to drop packets.
  • Understand the role of the various levels of Ethernet in a TCP/IP internetwork.
  • Diagnose how the Address Resolution Protocol works, including how it can negatively impact network performance.
  • Gain an understanding of DHCP including the many options that are regularly added to the protocol.
  • Use a variety of protocol analyzers to study the packets that are transmitted.
  • Analyze routing methods.
  • Learn how ICMP reports on problems in the network. And, discover how to interpret whether the ICMP message indicates a network can’t be reached, a host can’t be reached, or the packet is being dropped due to some other problem.
  • Develop a sense of when and where the many protocols are used.
  • Use the Spanning Tree algorithm with your switches and bridges when it is required.

What students say about this course:

" This class was an excellent technical overview. I especially like the focus on TCP performance."

    • M. Altland, Verizon

" This class was challenging but very well presented. The hands-on with the test equipment was particularly beneficial."

    • G. Burkholder, Sprint

" The TCP/IP class was technically very solid. Dr. Hippensteel did a great job of presenting it. Our group found it to be very worthwhile."

    • G. Downey, Hershey Foods
