Re: [Cerowrt-devel] anyone using sunshine?

Yes I have been using it successfully for the last couple of years and it works well. However the vaapi encoder path needed for non nvidia encoding has some bugs with how bandwidth calculation works for FEC insertion. So YMMV for anything above around 30mbit encodes (which is plenty for 4K

Whilst I understand it's not designed for High Bandwidth uplinks - how does it scale to 1 to 10Gbit symmetrical (or near symmetrical) uplinks ? One of the problems i've had with Cake is that it becomes CPU bound beyond around 3 or 4 gigabit. On Sat, 16 Apr 2022 at 07:41, Andrew Somerville

Re: [Cerowrt-devel] a smart SFP

Those are really high split rates. We (as in UFB in NZ) looked at 32:1 splits but it's rare - in practice it's often half that. Splits end up based on contention of regulated L2 plans which are sold to RSP's to on-sell to customers. Based on available backhaul bandwidth rather than any factor. i.e

Heat issues you mention with UTP are gone; with the 803.bz stuff (i.e Base-N). It was mostly due to the 10G-Base-T spec being old and out of line with the SFP+ spec ; which led to higher power consumption than SFP+ cages were rated to draw and aforementioned heat problems; this is not a problem
