5. SWITCH OPERATION
5.1 Address Table
The WGS-5225-8UP2SV is implemented with an address table. This address table is composed of many entries. Each entry is
used to store the address information of some nodes in the network, including MAC address, port no, etc. This information
comes from the learning process of WGS-5225-8UP2SV.
5.2 Learning
When one packet comes in from any port, the WGS-5225-8UP2SV will record the source address, port no., and the other
related information in address table. This information will be used to decide either forwarding or filtering for future packets.
5.3 Forwarding & Filtering
When one packet comes from some port of the WGS-5225-8UP2SV, it will also check the destination address besides the
source address learning. The WGS-5225-8UP2SV will look up the address-table for the destination address. If not found, this
packet will be forwarded to all the other ports except the port, which this packet comes in. And these ports will transmit this
packet to the network it connected. If found, and the destination address is located at a different port from this packet comes in,
the WGS-5225-8UP2SV will forward this packet to the port where this destination address is located according to the
information from address table. But, if the destination address is located at the same port with this packet comes in, then this
packet will be filtered, thereby increasing the network throughput and availability.
5.4 Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques. The WGS-5225-8UP2SV stores the incoming frame in an
internal buffer and does the complete error check before transmission. Therefore, no error packets occur; it is the best choice
when a network needs efficiency and stability.
The WGS-5225-8UP2SV 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
existence hubs, which nearly always improves the overall performance. An Ethernet switching can be easily configured in any
Ethernet network environment to significantly boost bandwidth using the conventional cabling and adapters.
Due to the learning function of the WGS-5225-8UP2SV, 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 in the same segment as the source address. This confines network traffic to its respective domain and reduce the
overall load on the network.
The WGS-5225-8UP2SV performs "Store and Fforward"; therefore, no error packets occur. More reliably, it reduces the
re-transmission rate. No packet loss will occur.
