Therefore, subnet level NSGs are really not necessary. In the Hub’s case, when all the computers send data packets, those are copied as a signal at the different ports of the hub. That means, the hub simply replicates the signal and the intended Repeating hubs are considered part of the collision domain and for reliable operation of a shared Ethernet network, the network diameter must not exceed the collision domain (see Figure 1). This distance limit is based upon the round-trip propagation delay between the two furthest stations on the network, and it cannot be such that collisions are not sensed by all stations within a prescribed We recommend an Ethernet switch over a hub, as we said, hubs are rarely even bought these days.
