The Ethernet Switch will lookup the address table for the destination
address. 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 located at different port from this packet comes
in, the Ethernet Switch will forward this packet to the port where this
destination address is located according to the information from
address table. But, if the destination address is located at the same port
with this packet comes in, when this packet will be filtered. Thereby
increasing the network throughput and availability
Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques. A
Store-and-Forward Ethernet Switch stores the incoming frame in an
internal buffer, do the complete error checking before transmission.
Therefore, no error packets occurrence, it is the best choice when a
network needs efficiency and stability.
The Switch scans the destination address from the packet header,
searches the routing table provided for the incoming port and forwards
the packet, only if required. The fast forwarding makes the switch
attractive for connecting servers directly to the network, thereby
increasing throughput and availability. However, the switch is most
commonly used to segment existing hubs, which nearly always
improves overall performance. A Ethernet Switch can be easily
