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 and check error before transmission. Therefore, no
error packets occur when buffers are received from end users. It is
the best choice when a network needs efficiency and stability.
The Ethernet 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. An Ethernet Switch
can be easily configured in any Ethernet network environment to
significantly boost bandwidth using conventional cabling and adapt-
ers.
Due to the learning function of the Ethernet Switching, the source
address and corresponding port number of each incoming and
outgoing packet are stored in a routing table. This information is
subsequently used to filter packets whose destination address is on
the same segment as the source address. This confines network
traffic to its respective domain, reducing the overall load on the
network.
