Switch Operation
Address Table
The Switch is implemented with an address table. This address
table composed of many entries. Each entry is used to store the
address information of some node in network, including MAC
address, port no, etc. The information comes from the learning
process of Ethernet Switch.
Learning
When one packet comes in from any port. The Ethernet Switch
will record the source address, port no. and the other related
information in address table. This information will be used to
decide either forwarding or filtering for future packets.
Forwarding & Filtering
When one packet comes from some port of the Ethernet Switch,
it will also check the destination address besides the source
address learning. The Ethernet Switch will lookup the address
table for the destination addresses. If not found, this packet will
be forwarded to all the other ports except the port which this
packet comes in. And these ports will transmit this packet to the
network it connected. If found, and the destination address is
