Abstract
In a network system comprising a plurality of secondary LAN's of different types operable at a relatively low speed, a single primary LAN accommodating the secondary LAN's and operable at a relatively high speed, and a plurality of bridges for connecting the primary LAN and the secondary LAN's, a communication frame transmitting on the primary LAN includes an identifier representative of the type of a secondary LAN to which a source terminal belongs and a bridge receiving the primary LAN frame carries out a protocol processing on the basis of the identifier representative of the type of the secondary LAN.
