GE-DS-242-PoE Managed Ethernet Switch User Manual 

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 pro-vided 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 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 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 reduce 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. 

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 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. 
 

If attached device is: 

100Base-TX port will set to: 

10Mbps, no auto-negotiation 

10Mbps. 

10Mbps, with auto-negotiation 

10/20Mbps (10Base-T/Full-Duplex) 

100Mbps, no auto-negotiation 

100Mbps 

100Mbps, with auto-negotiation 

100/200Mbps (100Base-TX/Full-Duplex)
