AfterUpSwitchBufferBandwidthRule is an emergency rule based on BufferBandwidthRule. It kicks in if the last fragment downloaded is higher quality than the previous one and it recommends a lower bitrate if the current quality is cleary unsustainable.
It works like the BufferBandwidthRule, only on a single fragment (the last downloaded) and only if that fragment is the first from a higher quality level. In addition to the BufferBandwidthRule, this rule will not kick in (will return a zero-confidence recommendation) if the bandwidth is above an acceptable level.

|---|---|---|---|
 | bufferFragmentsThreshold : Number
The number of fragments in the buffer above which no lower bitrates are recomended.
For example, assume the bandwidth has a value of 3000 kbps and the actual bitrate is 5000 kbps.
If the number of fragments in the buffer is below the threshold, the rule will recommend 3000 kbps; otherwise, it will recommend 5000 kbps
