7. SWITCH OPERATION
7.1 Address Table
The Switch is implemented with an address table. This address table composed of many entries. Each entry is used to store the address information of some node in network, including MAC address, port no, etc. This
7.2 Learning
When one packet comes in from any port, the Switch 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.
7.3 Forwarding & Filtering
When one packet comes from some port of the Ethernet Switching, it will also check the destination address besides the source address learning. The Ethernet Switching will lookup the
7.4 Store-and-Forward
The Ethernet Switch scans the destination address from the
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
