Network architecture

An electronic-time-division multiplex circuit-switched network comprising:

• a plurality of nodes, each node comprising one or more transceivers and being configured to implement time-division multiplexing such that each node, at a given time, belong to one of a plurality of transmitting groups or one of a plurality of receiving groups;
• a plurality of one-to-many switches, wherein each transceiver of each of a transmitting group of nodes of the plurality of nodes is connected to a one-to-many switch of the plurality of one-to-many switches;
• a plurality of many-to-one switches, wherein each transceiver of each of a receiving group of nodes of the plurality of nodes is connected to a many-to-one switch of the plurality of many-to-one switches;
• and
• a plurality of subnetwork units, wherein each port of each of the one-to-many switches and the many-to-one-switches connects to a different subnetwork unit, and wherein each subnetwork unit is configured to connect a respective different set of nodes belonging to the transmitting and receiving groups.
