Understanding Hops
In its simplest terms, 1 LAN is equal to 1 hop, where the LAN is the span between
two AVB switches (also known as ‘bridges’). Take a look at the examples below. These
examples are fairly straightforward: one LAN connection equals one AVB hop.

In this next example, the EarMix 16M has a third hop because the input
channels from the NSB16.8 stage box are being routed to the StudioLive
16, where they are processed by the Fat Channel and added to FlexMixes
before they are then sent back out to the network and on to the EarMix 16M,
making three total hops between the NSB 16.8 and the EarMix 16M.

The more switches or devices that are cascaded, the more potential for additional
hops being added between devices on your network. As hops are added,
the potential for the latency between the source and destination to exceed
the limits set by the AVB specification is increased. Because of this, PreSonus
recommends a maximum of six hops between source and destination.
