I like to think of the transport layer as the layer of the OSI Model that enables more interesting traffic. While we network engineers may love a lot of the simpler uses of the IP protocol and ...

The two most common transport layer protocols are the transmission control protocol (TCP) and the user datagram protocol (UDP). One of the main differences between the two protocols is reliability.

Here's a pretty interesting experiment by someone curious if it was possible to implement a new transport layer protocol, basically something totally different than the existing few than everything ...

In the last newsletter we started discussing the protocol stack used for transporting voice over IP. Today we’ll move to the control for those conversations. By the way, before we get all those e-mail ...

In this first installment of a two-part lesson, we will discuss the difference between IP video that is carried by TCP and IP video that is carried by UDP. They behave very differently on the network.

In the previous two articles, I described the hardware and software required to build an IoT device. These devices (the “Things” in the Internet of Things) are an essential part of an IoT system.

Do you remember when we used multi-protocol routing for IPX, AppleTalk, and TCP/IP running on the same network? In the 1980s and early 1990s many enterprises had multiple protocols running on the ...

All too often we shy away from the depths of IP protocols, leaving the application vendors such as Microsoft; Wowza Media Systems, LLC; RealNetworks, Inc.; Adobe Systems, Inc.; and others with more ...

Trying to understand every detail involved in creating an embedded product that communicates via Internet protocols can be a daunting task. These protocols were created for systems that generally have ...

Welcome! Throughout this course, Network Systems Foundations, you will delve into the fundamental layers of network communication. You will start with a thorough discussion of the Link Layer and its ...
