3.4 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. 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 Ethernet Switching, the
source
address
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.
3.5 Auto-Negotiation
The STP ports on the Switch have built-in "Auto-negotiation".
This technology automatically sets the best possible bandwidth
