If you want low latency, you need to support datagrams, and have some 
way to fragment long frames over series of datagrams. But then, if you 
require reassembly of fragmented frames at each step in the relaying 
chain, you can easily run into head-of-line blocking. That's something 
we can handle in MoQ. I don't know whether HESP does that -- the specs 
do not appear to be publicly available.
