Hi everyone,
I was trying to understand the following snippet in 4bitle:
void updateNeighborTableEst(am_addr_t n) {
minPkt = BLQ_PKT_WINDOW;
...
totalPkt = ne->rcvcnt + ne->failcnt;
if (totalPkt < minPkt) {
totalPkt = minPkt;
}
if (totalPkt == 0) {
ne->inquality = (ALPHA * ne->inquality) / 10;
}
...
updateNeighborTableEst() is only called when at least BLQ_PKT_WINDOW of
packets are received, meaning totalPkt is equal to or larger than
BLQ_PKT_WINDOW. Why is it necessary to compare totalPkt with minPkt and
consider the case totalPkt is zero? Thank you for clarification.
