In our last meeting, we had a lot of good discussions on the latency objective and we ended up with a draft latency objective as below
“ Support a low latency mode of operation with ≤ 1.5usec latency for constrained link segment specifications (e.g., insertion loss or noise)”
Personally I like this wording because it links the low latency to constrained link segment in IEEE 802.3 language.
There is one point that is not quite clear to me is that “ ≤ 1.5usec latency” is for transmit, or receive or the sum of transmit and receive. Based upon what we have discussed in last meeting, this “ ≤ 1.5usec latency” should be the sum of transmit and receive latency. I would like to propose the following modification as highlighted in red to make it clear.
“ Support a low latency mode of operation with ≤ 1.5usec of the sum of transmit and receive latency for constrained link segment specifications (e.g., insertion loss or noise)”
Any comments here?
