Re: [Question #229367]: three parameters


Question #229367 on rohc changed:

    Status: Open => Answered

Didier Barvaux proposed the following answer:

ROHC feebacks may be transmitted in 2 different ways: with a ROHC packet
(piggybacking) or alone. The 1st way is preferred by the library (every
ROHC packet generated will try to piggyback several feebacks), but it is
not enough sometimes. If traffic is asymmetric, there are perhaps not
enough reverse traffic to transmit all the ROHC feedbacks. In such a
case, feedbacks are recorded in the compression context
(feedbacks_first, feedbacks_first_unlocked and feedbacks_next are a ring
of feedbacks) and must be flushed by the application manually. The
flush_feedback() function does this.
