IEEE standard for gigabit Ethernet is IEEE 802 3z The only cabling media approved is the fiber optic pair The IEEE has already begun discussions to standardize 10Gbps 10Gig Ethernet Ethernet Products Hub One of the earlier connection solutions for Ethernet a hub also called a repeater operates by broadcasting data to all ports simultaneously and repeating the process until the data is received by the intended node The hub works through a shared network with all of the nodes in the network segment sharing the same collision domain Switches and bridges emerged because of a need to separate collision domains that are too large therefore improving performance and network reliability User s Manual 17 Switch A switch solves the collision problem by working as a single domain A Switch maps the physical Ethernet addresses of the nodes residing on each network segment and then allows only the necessary traffic to pass through Packets of data are transmitted along with the destination and source segment There are two basic architectures of LAN switches cut through and store and forward Cut through switches consider only the destination address before forwarding it on to its destination segment but store and forward architecture accepts and then analyzes the entire packet before forwarding This allows the switch to stop certain packet errors from propagating through the network The store and forward switch eliminates
