transmission. Therefore, no erroneous packets will occur, making it the best choice
when a network needs efficiency and stability.
The industrial managed switch scans the destination address from the packet header
and searches the routing table provided for the incoming port and forwards the packet 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 the
overall performance. Ethernet switching can be easily configured in any Ethernet
network environment to significantly boost bandwidth using conventional cabling and
adapters.
Owing to the learning function of the industrial 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 on the same segment as the source address. This confines network traffic to
its respective domain and reduces the overall load on the network.
The industrial managed switch performs Store-and-Forward, preventing errorneous
packets and reducing the re-transmission rate. No packet loss will occur.
Auto-negotiation
The STP ports on the industrial managed 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 of both devices that are connected. Both the
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.
