CSMA/CD only requires that you back off if there actually is a collision. CSMA/CA additionally requires that for every frame sent, after sensing the medium as clear, that you wait for a random amount of time before sending it to avoid collisions. If the medium is frequently clear, CA will still have the overhead of this initial wait where CD will not.
- anonymousiam 10mo agoDepending upon how it's actually implemented, CSMA/CA may have the same (untended?) behavior of CSMA/CD in the sense that setting TCP_NODELAY will also set the backoff timer to zero. It would be interesting to test. (My other post in this thread mentions it.) https://news.ycombinator.com/item?id=46360209#46361580 https://news.ycombinator.com/item?id=46360209#46361580
