Networking requirements(latency, bandwidth, throughput) for EP vs TP?

I'm curious about the differences in networking requirements between EP and TP, particularly regarding latency, bandwidth, and throughput. I know that both distribution strategies are highly demanding in terms of networking performance, but I'm not sure which one has higher requirements from latency, bandwidth, and throughput perspectives. Could someone elaborate on this a little for me?

I also know that NCCL wasn't well-optimized for all-to-all which EP requires, and that's why DeepEP was introduced. But why can NCCL meet TP's requirements? Is it because NCCL is well-suited for allreduce, or is it because TP is more tolerant of networking limitations compared to EP?

Thanks.
