So, since Corundum is open source, you can plug in whatever arbitrary transmit scheduler you want. Corundum also supports 10,000+ transmit queues (I have synthesis tested on the ultrscale+ to 32,768 transmit queues). This is super interesting for all sorts of networking applications, as that's a large enough number of queues to give individual flows or connections their own hardware queue, so the scheduler on the NIC can directly control the flow of information leaving the NIC. TDMA is basically a simple demonstration scheduler that enables and disables queues on microsecond timescales, based on PTP time. One of the original reasons for building Corundum was to enable optical switching research, where data transmission into the switch must be precisely coordinated with the configuration of the switch itself. We have tried to do this in software, but the precision is limited and the CPU overhead is high. With corundum, the schedule is enforced in hardware, so it is extremely precise and does not add any CPU overhead.
