3 hub rule

by Raffi_ In reply to 3 hub rule

You are actually talking about PART of a rule here - the 5-4-3 rule

An Ethernet signal can travel through: a maximum of 5 segments, a maximum of 4 Repeaters/hubs, a maximum of 3 populated segments

(Populated segments have more than 2 nodes connected, un-populated segments have only a node at each end, so a 10baseT-segments is a non-populated segment).

There can be more repeaters/hubs in the complete network, and an Ethernet signal can pass-by more than 4 Repeaters/hubs, as long it does not have to go THROUGH more than 4 Repeaters/hubs.

If these rules are violated, the network becomes unreliable.

Here is a decent link on the subject:

It means you can not link more then 3 more hubs!

a -- b --- c --- d

a,b,c, & d are hubs. Each one is connected to the other from a crossover cable or port on the hub.

a -- b -- c -- d -- e

a,b,c,d, & e are hubs. This will not work because it breaks the 3 hub rule. Hub e makes four and nothing connected to it will connect to the network.

So the 3 hub rule is never connect more then 3 more hubs.

This rule mostly pertains to the latency of the signal. If the path becomes too distant or the intermediate equipment becomes too numerous, the latency (delay) introduced will degrade the communication, depending on the topology and protocols in use. Most repeaters will acknowledge delivery of a packet to the sender. Connectionless protocols, like IPX will fare better than some others through lots of network devices.
