5.4 Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques. A Store-and-Forward Managed Switch stores the incoming
frame in an internal buffer and do the complete error checking before transmission. Therefore, no error packets occur; it is the
best choice when a network needs efficiency and stability.
The Managed 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
existence hubs, which nearly always improves the overall performance. An Ethernet switching can be easily configured in any
Ethernet network environment to significantly boost bandwidth using the conventional cabling and adapters.
Due to the learning function of the Managed Switch, 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 in the same segment as the source address. This confines network traffic to its respective domain and reduce the overall load
on the network.
The Managed Switch performs "Store and Fforward"; therefore, no error packets occur. More reliably, it reduces the
re-transmission rate. No packet loss will occur.
5.5 Auto-Negotiation
The STP ports on the Switch have built-in "Auto-negotiation". This technology automatically sets the best possible bandwidth
when a connection is established with another network device (usually at Power On or Reset). This is done by detecting the
modes and speeds both connected devices are capable of. Both 10BASE-T and 100BASE-TX devices can connect with the
port in either half- or full-duplex mode. 1000BASE-T can be only connected in full-duplex mode.
