from the frames before transmission. No error packets
occurrence, it is the best choice when a network needs
efficiency and stability.
The Industrial Fast 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 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 Industrial Fast Ethernet
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 on the same segment as the
source address. This confines network traffic to its respective
domain, reducing the overall load on the network.
The Industrial Fast Ethernet Switch performs "Store-and-
Forward" therefore, no error packets occur. More reliably, it
reduces the re-transmission rate. No packet loss will occur.
Auto-negotiation
The TP ports on the Industrial Fast Ethernet 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 at the second of
both device is connected and capable of, both 10Base-T and
100Base-TX devices can connect with the port in either Half-
or Full-Duplex mode.
