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 Gigabit 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 Gigabit 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 Gigabit Ethernet Switch performs “Store and Forward" therefore,
no error packets occur. More reliably, it reduces the re-transmission
rate. No packet loss will occur.
3.5 Auto-Negotiation
The STP ports on the Gigabit 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 detect 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. 1000Base-T can be only
connected in Full-duplex mode.
