Abstract
The switching circuit comprises an interface to the interior which comprises two-way gates which are connected to internal interfaces of other switching circuits of said network, each of said gates comprising a l-input and n-output receive circuit and an n-input and l-output transmit circuit, one input of the transmit circuit being connected to the output of a receive circuit different for each of the n inputs, and the input of each receive circuit of a gate being connected to the output of the transmit circuit of a gate of another switching circuit of said network.
Claims10
A digital data curst switching circuit for "self-routing" data bursts, i.e. data bursts which are capable of traversing the network simply by means of a header or preamble placed at the beginning of the data burst in accordance with pre-defined transmission protocol applicable to the network, comprising an interface to the interior of the network which comprises two-way gates which are connected to internal interfaces of other switching circuits of said network, each of said gates comprising a 1-input and n-output receive circuit and an n-input and 1-output transmit circuit, one input of the transmit circuit being connected to the output of a receive circuit different for each of the n inputs, and the input of each receive circuit of a gate being connected to the output of the transmit circuit of a gate of another switching circuit of said network.
