A network switching system is described. The network switching system comprises a first port coupled to a source, a second port coupled to a destination, and multiplexer means coupled to the first port and the second port for transferring data between the first port and the second port by selectively connecting the first port with the second port. The data is transferred from the source to the destination through the first port, the multiplexer means, and the second port. The network switching system further includes processing means coupled to the multiplexer means for assisting transmission of the data by receiving the data from the first port when the first port does not indicate a port for the destination. A method of transferring data from a source to a destination via a network switching system is also described.
