ABSTRACT:
A switch for high rate transfer of data and/or telecommunications includes several switchport devices for traffic cells and a switchcore device connected to the switchport device for routing the traffic cells inside from one switchport device to another. The switchport devices are provided in several groups. The switchcore device is formed by several switchcore units provided in rows and columns in a matrix. Each switchcore unit has at least as many inputs and outputs as there are switchport devices in a group of switchport devices. The switchcore units in each row have their inputs connected to the switchport devices in an individual group. The switchcore units in each column have their outputs connected to the switchport devices in the group of switchport devices having the same order as the order of the column in the matrix.
