Table 5.4: PLM network diameter guide

A cable connection from one network port to another is often referred to as a hop.

The maximum size of a network is often referred to as the network diameter. The optimal network diameter is defined by the time it takes for a packet to get from one device to another across the furthest point in the network, in terms of communication time.

Most of the time consumed in the path, generally referred to as latency, is the hardware reaction and transmission time. The time consumed for the packets to travel over the network Ethernet cables themselves is very small in comparison. If we assume 100 m copper cables for all hops, we can present some simple rules for how many hops are permitted from any Dante source device to any of its recieving
