Networks
work up and running. In this era of rapid expansion, response time was sec-
ondary to just making sure the network was functioning.
10Base2 (thinnet). As a result, the network was one large collision domain--
not to mention even one large broadcast domain. Despite these limitations,
Ethernet was used because it was scalable, effective, and somewhat inexpen-
sive compared to other options. ARCnet was used in some networks, but
Ethernet and ARCnet are not compatible, and the networks became two sep-
arate entities. ARCnet soon became history.
but the network was still one large broadcast domain. More and more users
were attached to the hubs used in the network, and soon the performance of
the network was considered extremely slow.
pus networks. Bandwidth helps compound these problems. The three per-
formance problems in traditional campus networks included collisions,
broadcasts and multicasts, and bandwidth.
devices could see and also collide with each other. If a host had to broadcast,
then all other devices had to listen, even though they themselves were trying
to transmit. And if a device were to jabber (malfunction), it could almost
bring the entire network down.
