The OSI model is used as the reference model for networking, IT professionals know it like the back of their hand and it's regularly used to describe various hardware capabilities such as a 'layer two switch' for example.
Knowledge of the OSI will immediately give you more confidence with networking. You will quickly learn exactly where IP lives in the process of sending a data packet from host to host, and it will also give you a far better understanding of how to troubleshoot basic networking problems.
This short course is your gateway to networking and as an AV professional you should know it's structure and you should be able to reference it when needed.
The term IP is consistently part of everyday conversations between AV professionals. We use it as a general term for packet switching over a network. But what exactly is IP, and what does it do?
This course will answer those questions, and give you clarity on how IP affects every part of an AV design and installation.
In many applications, a single Ethernet switch is sufficient to displace a single matrix switch. It makes a very compelling proposal when a 16x16 matrix switch, consuming 440 watts and seven rack units of space can be replaced by a 48-port Ethernet switch in a single rack unit, consuming only 161 watts.
Sometimes though, a single switch isn’t enough whether you’re using matrix switching or AV over IP. As systems grow larger and larger, the scalability, space saving, and cost advantages of SDVoE over the traditional matrix switch grow quickly.
Objectives:
- Follow a specific example of how to create a 144-port SDVoE AV-over-IP system using the NETGEAR M4300-96X switch as a base.
- Discover the rack-space saving and cost advantages of SDVoE
Network infrastructure has never been so important. As we move more and more packets of data across the 'physical layer' it's vital to ensure the medium we choose is up to the job.
In this course Andrew Jimenez from Anixter explains how an IP-based infrastructure supports an SDVoE installation.
As more AV distribution moves to IT infrastructure, it is critical for AV system designers and installers to understand some of the basic networking protocols that make this possible. Multicast is a crucial technology that allows high bandwidth streams to move around a network without overwhelming the entire network.
Objectives:
- Learn what multicasting is, and why it is necessary for any practical AV-over-IP solution
- Identify tools for configuring and troubleshooting multicast networks
- Understand the difference between multicasting and VLANs, and a little bit about how they interact
