Calrec IP Primer Part 5: Latency/Jitter

Welcome to the fifth in an eight-part series of articles on AoIP!

Over the next four weeks, we will be releasing an IP chapter every Wednesday as part of Calrec’s latest IP Primer. The IP Primer will build up your knowledge of IP and will enable you to create reliable AoIP networks to meet the needs of your desired workflow without defining or compromising operations.

We’ll look at Latency/Jitter, QoS, Switches and Network Design. This week we dive into Latency/Jitter in more detail.

On any network, latency and jitter are inevitable. They are inescapable consequences of having multiple clients sending and receiving packets of data on the same network. The good news is that for the most part, latency is deterministic, and there are ways to plan for jitter across an IP network. This chapter of Calrec’s IP Primer looks at what latency and jitter is, as well as how to plan for it to minimise any network disruption.

Calrec IP Primer Part 5: Latency/Jitter 

Network latency is inevitable – there is no getting around it, it is a simple scientific consequence of distance.

Latency is a key component to audio networks – in fact, it’s all around us, at all times. Mostly we learn to deal with it; what we hear has a natural latency which we have learned to anticipate and adjust to.

On the other hand, jitter is a change in the amount of latency within a specific transmission path, and this can change depending on the pressures on the network. Individual packets of data can be delayed more than others, or they can arrive in a different order from what they were sent.

In this chapter of Calrec’s IP Primer we look at how these fundamental principles can be anticipated and planned for, and which parts of the network we should be concentrating on to help keep them to a minimum.

We look at the impact of packetization and switch residency time, QoS policies and in-flight delay. We will also take a look at where jitter can be introduced and how we can mitigate that through buffering and clever configuration of link offsets, designed to work in tandem with the network.
