Abstract
An arrangement and method of operating a network switch arrangement in a packet switched network connects a plurality of multiport network switches which is in a circular, serial manner so that data is transferable between the network switches only unidirectionally. When it is determined that data is to be transmitted from a first network switch to a port in a second network switch, the data is transmitted over an expansion bus from the first network switch to the second network switch in a continuous stream of data bursts. This extremely fast transmission between the networks switches allows multiple multiport network switches to be cascaded together to effectively form a single network switch with at least twice as many ports.
