[ih] Better-than-Best Effort: Lower latency

[Toerless Eckert]

Seems though as if hollow fiber may be making a comeback:

Latency (old):

Loss (this is what seems new):

Guess it first needed HFT to pump money into radio links in the last decade before there was
enough financical interest to do more research into reducing loss for hollow fiber to make
it compete.

Hey, finally something good coming out of HFT ;-))
