V3 Fundamentals of Datacom and Networking - full quality preview · Video Tutorial V3: Packets vs. Frames · Datacom and networking training on DVD

In this course, we'll begin by establishing a model for a data communications circuit, then provide examples and context for each of the components of the model, and review different circuit configurations including LANs and WANs.

In the second chapter, we’ll look at how data is formatted for transmission, beginning with the older concepts of “synchronous” and “asynchronous”, then cover the newer ideas of frames and packets, how frames and packets are related, and the addresses on frames and packets, and the structure of IPv4 packets.

We'll complete this course with an understanding of the “Network Cloud”, why people use clouds to draw networks, and what is really going on inside that cloud.

This set of topics, particularly the understanding of packets and frames, the addresses on each, and how they are related; and the idea that there are three kinds of network services – and three kinds of edge equipment - is the foundation for all further study of LANs, WANs, IP and just about any other kind of communications, including Voice over IP.

V4 Understanding Networking 1 - full quality preview · Video Tutorial V4: The OSI Layers: The FedEx Analogy · Networking training on DVD

This course builds on the basic packet, frame and IP networking concepts of Course V3, Fundamentals of Datacom and Networking, to put in place a solid understanding of protocol stacks, the OSI model and layers and IP addressing including address classes, static vs. dynamic public vs. private and network address translation.

In Part 3, we move to the next higher level of knowledge, understanding packet networks and bandwidth on demand services from telecommunication service providers. After understanding the core concepts, including virtual circuits, we use the grand-daddy of packet services, X.25 to explain jargon: connection-oriented vs. connectionless and reliable vs. unreliable packet networks.

Then we progress through technologies: Frame Relay, ATM and finish with MPLS. We'll trace the flow of TCP and IP packets from server to client across Frame Relay, then see how the same TCP/IP works over MPLS.

IP over MPLS will end up replacing all other services including ISDN, T1s, Frame Relay, native ATM. Understanding the OSI layers, how a protocol stack works and TCP/IP over MPLS is career-enhancing knowledge.
