Straight through

- Mar 27, 2018 -

Through the Ethernet switch can be understood as the way in which the port is crisscrossed circuit matrix between the telephone switchboard. It detected in the input port when a packet, check the package in baotou, for the purpose of the package address, start the internal dynamic lookup table into the corresponding output port, the intersections on the input and output, the packets through the corresponding port, realize the exchange function. Because do not need to be stored, delay is very small, exchange, very fast, this is its advantage. Its disadvantage is that because the packet content has not been Ethernet switch, so can't check whether the transmission of packets is wrong, does not provide error detection ability. Since there is no cache, will not have different rate of input/output port connected directly, and easy to lost package
