4. ERATION 3 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 information comes from the learning process of Ethernet Switch 3 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 3 3 Forwarding amp 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 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 different port from this packet comes in the Ethernet Switching 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 increase the network throughput and availability 3 4 Store and Forward Store an
5. d 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 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 the 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 Nego
