Slowness in an IP WAN connection is generally much more difficult to diagnose and repair than can be remedied by answering a list of question or implementing a few steps.

In this month's Byte-Sized Lesson, we examine this protocol, a cornerstone of the world wide web that’s currently undergoing significant modifications.

In this lesson, we explore the data link level, one which is particularly important in the delivery of audio and is used in every implementation of TCP/IP.

In the second of a two-part lesson, we address some basic IP principles that seem to be overlooked: half duplex versus full duplex and statistical multiplexing.

In the first of a two-part series, we address some basic IP principles that are often overlooked in debates involving AV problem solving. Do you know them?

Latency is discussed widely in the AV industry. However, we’ll now focus on one aspect that is almost never considered: the impact of latency on TCP based video flows.

In the second part of this series, we dive into deeper detail about AV and IT standards, support tools, and the bridge that pro AV may provide for these two groups to move closer together.

The IT industry has recently begun devoting increased attention to the important role of network buffers, which are central to the delivery of data.

In this month's Byte-Sized Lesson, Phil Hippensteel discusses how to use ping and traceroute to troubleshoot network connectivity problems.

ICMP is a mandatory operating system extension that helps explain how IP traffic is functioning. In this lesson, we review the protocol and delve into how its applications can be used effectively.

By using a traditional IT tool to do a deep analysis of Netflix's video flow, we can learn techniques that are widely applicable to troubleshooting and to analyzing other types of audio and video.

Dr. Phil Hippensteel explains how the layered model of communications can guide a better understanding of network protocols.

To assess how well an IP video connection is working, it's important to consider the role of the users' method of accessing the network.

The decision to use Ethernet as a method of transporting audio is well established at this time. However, little discussion has been given to the way audio can impact the IT network.

When networks are used to deliver multimedia, timing becomes an issue. This lesson covers the technical mechanisms behind IP-related timing, as well as some of the many ways of managing it.

The AV industry is concerned with how its systems mesh with IT standards. But what about the other side? What exactly does IT care about when it comes to AV?

Internet RFCs (Requests for Comments) are one of the most significant influences on the conduct of the internet—and understanding their importance could hasten the integration of IT and AV.

We go over the pros and cons of a newer protocol for low-latency transport, Reliable Internet Streaming Transport, or RIST.

How well do you know your IT terminology? Dr. Phil Hippensteel breaks down the differences between terms like switches, routers, and gateways.

A central point of conversation around video delivery in pro AV is latency. Dr. Phil Hippensteel explains why ABR is limited in transmission rapidity.

Secure Reliable Transport (SRT) Alliance is publicizing its new protocol as a good way to deliver video, but is it backed by a solid technical design? Phil Hippensteel offers his verdict.
