4.4 Store-and-Forward
Store-and-Forward is one type of packet-forwarding
techniques. A Store-and Forward Ethernet Switching
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 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. A
Ethernet Switching can be easily configured in any
Ethernet network environment to significantly boost
bandwidth using conventional cabling and adapters.
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.
The Switch performs "Store and forward" therefore, no
error packets occur. More reliably, it reduces the
re-transmission rate. No packet loss will occur.
