Simultaneous Network Communications - HP ProCurve 2224 Installation Manual

flood - whenever a new destination address is found in a packet received
on a port, the destination address will not yet be in the switch's address
table and the Switch 2224 cannot know whether to forward or filter out
the packet. In this case, it sends the packet to all the other switch ports.
This is referred to as "flooding". When the destination device receives the
packet, it replies, and the switch learns the new address from the reply
packet. Then, all future packets destined for that address are forwarded
or filtered out appropriately.
Network Moves and Changes. When devices are moved in the network,
and become connected to a different switch port, the Switch 2224 automati-
cally recognizes the change and updates the address table with the new port
location of the device. Communication with the device is automatically main-
tained, without any address table manipulation being required.

Simultaneous Network Communications

As a part of the traffic isolation benefits provided by the Switch 2224 address
table operation, the switch enhances network performance because it can
conduct multiple, simultaneous network connections. Instead of sharing the
network bandwidth, as in connections to a hub, each connection has its own
10 Mbps, or 100 Mbps.
