Embodiments of the invention relate to the dynamic creation of TT paths in a large computer network having computer nodes, communication channels, and distribution modules (DMs), which all have access to a global time base, wherein a scheduling instance, aimed at establishing a time-controlled path with specified path time characteristics from a transmitting to a receiving node along an existing virtual connection (VC), requests from each DM in the VC all the TT path descriptor lists (TTPDLs) confirmed by said DMs, then transmits the specified path time characteristics and all confirmed TTPDLs to a dynamic scheduler that creates a new TTPDL for each DM in the VC, the existing reserved TTPDLs of the DMs affected remaining unchanged, wherein the corresponding new TTPDLs are transmitted to each DM in the VC, and wherein each DM in the VC reserves the TT path requested and confirms the reservation to the scheduling instance.
