8+ Hours of Video Instruction

This video considers the engineering problems to solve when transporting data from one device to another over a network and the solutions available for those problems. The presentation follows the pattern of the Recursive InterNetworking Architecture, or RINA, model, in breaking the problems down into marshaling, multiplexing, error handling, and flow control. For each of these four problems, a set of solutions is presented, such as marshaling grammars, addressing, forward error correction, and windowing. After the theoretical foundation is in place, several implementations are discussed to fill out the problems and solutions presented. The video also considers the problem of interlayer discoveryand some of the solutions available in this spaceto provide a complete picture of data transport in a computer network.

Many engineers find themselves sipping from the firehose, trying to learn and understand a rapidly-changing set of technologies to solve ever-changing business requirements. The problems that need to be solved to carry data from one host to another, whether physical or virtual, however, were discovered early in the process of designing networks and protocols. The set of solutions to these problems, while expressed in a bewildering variety of products, technologies, and protocols, is also more constant that it might initially appear.

By learning the basic problems required to transport information across a network, and a common set of solutions to those problems, engineers can anticipate new technologies. New technologies are almost always a new implementation of some already known solution, designed to solve a problem that is already well-understood. By learning these common problems, and a range of solutions for each one, engineers can learn to ask the questions needed to quickly guide their learning in new technologies and products, as well as in quickly understanding where any solutions may face implementation or theoretical problems.

Skill Level

  • Beginner to Expert

Learn How To

  • Understand the problem space of transporting information across a network
  • Explain the most common solutions for resolving the problems involved in carrying information across a network
  • Gain a solid understanding of many common protocols and solutions
  • Learn about a common, but often neglected, area of network operationtransporting data through a network
  • Develop the mental tools required to think about how networks work
  • Develop the mental tools required to ask the right questions about new technologies and protocols as they are developed, allowing you to quickly understand new technologies and products as they are released by relating them to previously developed technologies
  • Develop the ability to understand why particular implementation choices were made, and what the tradeoffs are in each situation
  • Enhance troubleshooting ability by understanding how each technology works and what problems might arise with any particular solution

Who Should Take This Course

The target audience for this video includes:

  • Beginning learners just starting a career in network engineering
  • Intermediate-level network engineers who have some experience, and perhaps an associates or professional-level certification, who would like to take their career to the next level
  • Experienced network engineers who would like to fill in their knowledge, or understand why things work the way they do, rather than simply how they work
  • Programmers who would like to understand the operation of networks in order to improve their ability to write network-based applications
  • Development operations engineers who would like to understand why networks operate the way they do, and possible migrate into full-time network engineering roles
  • College students who are taking courses in or majoring in information technology who would like to supplement their learning in the network engineering space
  • College students taking a course, which uses the Problems and Solutions in Network Engineering book as course material, and would like additional material to help them to better understand the material

The market for this product is not restricted to a small subset of learners, as it addresses fundamental concepts in a way that is applicable for many different kinds of students in a wide variety of learning situations.

Lesson Descriptions

Lesson 1: Modeling Network TransportLearn the importance of layers, the DoD and OSI models, and then meet the Recursive Internet Architecture (RINA) model used throughout the rest of the course.

Lesson 2: Fundamental ConceptsDiscover connection-oriented vs. connectionless networks, as well as how they translate to circuit switching and packet switching. These are foundational ideas for all network transport.

Lesson 3: MarshalingInvestigate what makes a frame a frame, and what makes a packet a packet. We'll explain this by discussing grammars and dictionaries, fixed vs. variable-length fields, and maximum transmission unit sizes.

Lesson 4: Error HandlingFind out what network errors are, learn how network errors are detected and corrected, and then consider the tradeoffs of bothering with error detection at all.

Lesson 5: MultiplexingUnderstand how multiple network consumers can use the network at the same time to transport data. This is done through addressing as well as various types of casting.

Lesson 6: Flow ControlDiscover different flow control techniques that avoid network congestion and improve overall transport efficiency in this discussion of collisions, goodput, and TCP algorithm fundamentals.

Lesson 7: Lower Layer Transport ExamplesView WiFi through the lens of the RINA model as we examine full wireless frames, radio theory, the impact of radiated power, frame prioritization, error checking, and more.

Lesson 8: Higher Layer Transport ExamplesAgain using RINA as our reference, probe IP, IPv4, IPv6, and QUIC with us. Although these protocols vary in details, the patterns are similar as we move up and down the stack. Being able to see patterns is key.

Lesson 9: Interlayer DiscoveryNot every layer of the transport stack knows what it needs to know to put a packet on the wire. Using DNS, IPv6, and CLNS as examples, we'll explain how layers inform one another so that a packet can be sent.

Lesson 10: Transport SecurityConsider authentication, authorization, and privacy, all building blocks for a secure transport. We'll explain these concepts by way of WireGuard, a modern virtual private network protocol.
