Technologies generally described herein relate to waved time multiplexing. In some examples, a command flit can be transmitted from a sender node of a network-on-chip (“NOC”) to a destination node of the NOC via an intermediate node along a circuit-switched path. The command flit can include an interval period and a release duration. When the command flit has been transmitted, one or more data flits can be transmitted from the sender node to the destination node via the intermediate node along the circuit-switched path. The sender node, the destination node, and the intermediate node can be configured to reserve router resources of the sender node, the destination node, and the intermediate node respectively for circuit-switched traffic during a use duration of the interval period and to release the router resources for packet-switched traffic during the release duration in a waved time multiplex arrangement.
