(1) You trigger image acquisition and during this time period, the camera acquires and transmits
a frame. The bandwidth reserve setting would allow 5 resends during this time period, but no
resends are needed. The accumulator pool started with 15 resends available and remains at
15.
(2) You trigger image acquisition and during this time period, the camera acquires and transmits
a frame. The bandwidth reserve setting would allow 5 resends during this time period, but 7
resends are needed. The 5 resends available via the bandwidth reserve are used and 2
resends are used from the accumulator pool. The accumulator pool is drawn down to 13.
(3) You trigger image acquisition and during this time period, the camera acquires and transmits
a frame. The bandwidth reserve setting would allow 5 resends during this time period and 4
resends are needed. The 4 resends needed are taken from the resends available via the
bandwidth reserve. The fifth resend available via the bandwidth reserve is not needed, so it is
added to the accumulator pool and brings the pool to 14.
(4) You trigger image acquisition and during this time period, the camera acquires and transmits
a frame. The bandwidth reserve setting would allow 5 resends during this time period, but 10
resends are needed. The 5 resends available via the bandwidth reserve are used and 5
resends are used from the accumulator pool. The accumulator pool is drawn down to 9.
(5) You trigger image acquisition and during this time period, the camera acquires and transmits
a frame. The bandwidth reserve setting would allow 5 resends during this time period, but 20
resends are needed. The 5 resends available via the bandwidth reserve are used. To
complete all of the needed resends, 15 resends would be required from the accumulator pool,
but the pool only has 9 resends. So the 9 resends in the pool are used and 6 resend requests
are answered with a "packet unavailable" error code. The accumulator pool is reduced to 0.
