Abstract:
Methods, systems, and apparatuses for scheduling a plurality of Virtual Links (VLs) in a Time-Triggered Ethernet (TTE) network by determining a subset of a group of bins allocated to TT traffic; restricting the subset bin groups to a specified harmonic subdivided pattern with a certain duration; allocating the subset of bin groups in accordance with bin group equated with a rate at least twice as high as a highest TT traffic rate available in the network to enable control of partitioned traffic by using a set of media reservations; checking whether a bin selected via a bin selection process for scheduling a TT Virtual Link (VL) is a valid TT bin, else proceeding to a subsequent bin until a valid TT bin is returned for the TT VL, and reserving using at least one media reservation for a TT VL to be scheduled by temporal partitioning at the restricted rate.
