問題文
An RTP stream test between two agents reports a rising Discards figure while the Loss figure stays low. How does the documentation define Discards, and what does it advise about the buffer that is involved?
選択肢
- Packets thrown away in transit because a queue along the path overflowed, expressed as a percentage of packets sent, with the buffer advised to be as small as the round-trip latency from the sender allows.
- Packets thrown away at the sender because the stream exceeded the configured duration, expressed as a percentage of packets sent, with the buffer advised to be as large as the path latency of the stream.
- Packets thrown away at the destination because the codec exceeded its own budget, expressed as a count per test round, with the buffer advised to be as large as the codec's frame.
- Packets thrown away at the destination because the delay variation exceeded the de-jitter buffer setting, expressed as a percentage of packets sent, with the buffer advised to be as large as the packet delay variation.
